There is now a Debian Jessie package available. Please see Kamikaze#Manual_installation_of_package_feed for instructions on adding the feed manually, if you are not using the preferred distro which is Kamikaze.
- All units are in SI-units internally in Redeem, but g-codes often expose mm etc.
- default.cfg is the bible, all configs must be defined in there.
- All configurations in default.cfg can be overridden
- default.cfg and printer.cfg can be changed with updates. local.cfg can not.
- Here is the config hierachy: local.cfg > printer.cfg > deafult.cfg
Most of redeem is written in Python, but if you look at a typical G-code file you will see that most of it is G0/G1 codes, so that part has been optimized. That way you can have seldom used routines like homing and bed levelling done in a python with all it's garbage garbage collection and libraries, and just asmall part done in C.
For Redeem, the preferred way to handle configuration is through the web interface. The web interface is available through  assuming you have your BeagleBone on the local network and you are using Kamikaze
The config files for redeem are present in the folder /etc/redeem/. There are three files for setting the configuration. default.cfg is the catch-all at the bottom. It will contain all the possible options and should not be touched. Second is printer.cfg which is a symlink and specific to a printer. Look in the folder to find one that matches your printer. If you cannot find one, make it! Otherwise leave the existing one as is. Finally is local.cfg which contains quirks or other individual settings. The local.cfg will not be overwritten by new software updates and can contain stuff like microstepping, stepper current, offsets as well as any bed compensation matrices etc.
Now normally all settings can come from your specific printer.cfg config file, but if no one has made that file, you need to set this stuff up yourself. Most of the stuff in the config files is in SI units. This is perhaps different than what other firmwares do, where the focus is on optimization rather than ease of use. Note that it is important to keep the section headers in the same case as the examples or default.cfg as they are case sensitive.
Tip: If you edit a config file incorrectly, redeem will fail to load and you will be unable to connect in octoprint. You must use headers, as shown in the examples, and consistent spacing/formatting. Also the first time you load octoprint you will not have any config files listed in settings/redeem, you are supposed to load a blank local.cfg file. You shouldn't need to do this again unless you reflash the image. However, if you find that your config files suddenly when missing, simply close your browser tab and reopen octoprint and they should return.
If you are not writing your own new printer.cfg, keep all your printer settings in local.cfg to avoid getting any setting over-written by a redeem update.
There are some comments for the different config variables, but here is a more detailed explanation on some of them:
The system section has only Replicape board revision and log level. For debugging purposes, set the log level to 10, but keep it at 20 for normal operations, since logging is very CPU intensive and can cause delays during prints at high speed. On later versions of Redeem, the board revision is read from the EEPROM on the Replicape.
[System] # CRITICAL=50, # ERROR=40, # WARNING=30, INFO=20, DEBUG=10, NOTSET=0 loglevel = 20 # If set to True, also log to file. log_to_file = True # Default file to log to, this can be viewed from octoprint logfile = /home/octo/.octoprint/logs/plugin_redeem.log # Plugin to load for redeem, comma separated (i.e. HPX2Max,plugin2,plugin3) plugins = # Machine type is used by M115 # to identify the machine connected. machine_type = Unknown
Right now, there are only a few working plugins.
- HPX2Max: Dual extrusion with the HPX2Max extruder.
- DualServo: A more general dual extrusion using a servo for switching between hot ends.
DualServoPlugin, example config:
[DualServoPlugin] # The pin name of where the servo is located servo_channel = P9_14 # minimum pulse length pulse_min = 0.01 pulse_max = 0.02 angle_min = 0 angle_max = 180 extruder_0_angle = 87.5 extruder_1_angle = 92.5 [HPX2MaxPlugin] # The channel on which the servo is connected. The numbering correspond to the Fan number servo_channel = P9_14 # Extruder 0 angle to set the servo when extruder 0 is selected, in degree extruder_0_angle = 20 # Extruder 1 angle to set the servo when extruder 1 is selected, in degree extruder_1_angle = 175
The geometry section contains stuff about the physical layout of your printer. What the print volume is, what the offset from the end stops is, whether it's a Normal XY style printer, a Delta printer, an H-belt type printer or a CoreXY type printer.
It also contains the bed compensation matrix. The bed compensation matrix is used for compensating any rotation the bed has in relation to the nozzle. This is typically not something you write yourself, but instead it is found by probing the bed at different locations by use of the G-code G29. The G29 command is a macro command, so it only runs other G-codes and you can override it yourself in the local.cfg file or in the printer.cfg file if you are a printer manufacturer.
Note on homing
travel_*, offset_*, and home_* (not in this section, see the #Homing section) all make up how a homing routine works. They can all be positive or negative. Here is a quick run-down of what is happening internally:
- Travel the distance and direction set in travel_*. If an end stop is found, stop.
- Move away the distance found in backoff_distance_*, then hit the end stop once more, slower.
- Move the distance set in offset_*, opposite of travel_*. The offset_* sign is thus typically the same as the travel_* sign.
- If the values in home_* is 0, the routine is done and the position is 0, 0, 0.
- If there are values in home_*, use those values in the G92 command, so that the printer will then move to that point, changing the position.
Offset_* does homing in cartesian space, so for a delta, the values, typically have to be the same if you want the nozzle to end up in the centre, right above the platform. After completing the offset_*, a G92 is issued _with_ the values in home_* as arguments. If home_* is 0, the homing routine is done, but if there are some values in home_*, the head will move to those positions. the values in home_* are in the native coordinate system, IE delta coordinates for a delta printer. As a starting point, have home_* values = 0, set the travel_* to a small value and offset_* to an even smaller value. That way you can do some testing without ramming your nozzle into the bed.
[Geometry] # 0 - Cartesian # 1 - H-belt # 2 - Core XY # 3 - Delta axis_config = 0 # The total length each axis can travel # This affects the homing endstop searching length. # travel_* can be left undefined. # It will be determined by soft_end_stop_min/max_* # travel_x = 0.2 # ... # Define the origin in relation to the endstops # offset_* can be left undefined. # It will be determined by home_speed and soft_end_stop_min/max_* # offset_x = 0.0 # ... # The identity matrix is the default bed_compensation_matrix = 1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0
Delta support in Redeem is now pretty stable. variables needed for defining the geometry of the delta setup. If your printer is not a Delta printer, leave this.
Effector is the thing that is in the centre and moves. The one with the hot end.
The distance from the centre of the effector to where the rods are mounted is the effector offset.
Carriage is those that move up and down along the columns.
I've not figured out what the carriage offset does. You should think this was the offset from the carriages to the rods, but I've not gotten that top work. Seems broken. Instead, add the carriage offset to the effector offset.
calibrating convex/concave behaviour
If your delta printer is exhibiting non-planar behaviour, you can use #M665:_Set_delta_arm_calibration_values to calibrate the values. When you have found the correct values, save them with #M500:_Store_parameters_to_file. The saved settings will be in local.cfg
To see which parameter to change in which direction, looking at this page will guide you in which value to tune which way: Delta Calibration Study
To summarize, set your rod length L according to what you have measured, from center to center of the ball joints. Then adjust the behavior by adjusting the R parameter.
Use a thickness gauge (can be anything that doesn't compress) of a few millimeters thickness as a reference. First set the Z-height properly for X,Y = (0,0). Then move 10, 20 millimeters in X and Y around the center to see if you have a significant error in the planar behavior. If you don't, move out further and check with your thickness gauge how far off you are. A quick example of the order of magnitudes is if you notice a 1 to 1.5mm offset (upwards means you need to shrink R, too far down means you need to increase R) at 40mm off center out of a 3mm gauge. The error in radius was somewhere on the order of 2 or 3mm to adjust it. The further out from the center, the smaller the adjustment to be made to the radius.
Note: while the radial offset values exist, it has been reported that at present they do not behave as expected. The suggested fix is to subtract the offsets directly into your print radius value to get a better behavior. This note will be removed when the release branch of redeem has corrected the behavior.
bed levelling compensation matrix Redeem supports autoprobing the bed to generate a bed levelling compensation matrix. However it is no substitute for a poorly setup machine. Try to get your head as level as possible without bed levelling first, then use the #G29:_Probe_the_bed_at_specified_points command to generate the fine-tuning bed compensation matrix.
Using G33 for auto-calibration
When you have a working G29 probing setup in place, you can improve several parameters of your delta printer with the G33 command. The parameters to improve is end stop offsets, delta radius, tower angular position correction and diagonal rod length.
G33 will use the probe offset in the [Probe] section to adjust the end stops offsets, so be sure to set this to 0 initially to avoid offset errors.
The G33 in Redeem is an implementation of the calculations found in this web site: http://escher3d.com/pages/wizards/wizarddelta.php
[Delta] # Distance head extends below the effector. Hez = 0.0 # Length of the rod L = 0.135 # Radius of the columns (distance from column to the center of the build plate) r = 0.144 # Effector offset (distance between the joints to the rods to the center of the effector) Ae = 0.026 Be = 0.026 Ce = 0.026 # Carriage offset (the distance from the column to the carriage's center of the rods' joints) A_radial = 0.0 B_radial = 0.0 C_radial = 0.0 # Compensation for positional error of the columns # (For details, read: https://github.com/hercek/Marlin/blob/Marlin_v1/calibration.wxm) # Positive values move the tower to the right, in the +X direction, tangent to it's radius A_tangential = 0.0 B_tangential = 0.0 C_tangential = 0.0
Here is a visual depiction of what the length and radius looks like. Here is what the Hez looks like.
Ah, Steppers! This section has the stuff you need for the the steppers, such as the number of steps pr mm for each axis, the stepper max current, the microstepping, acceleration, max speed, the option to invert a stepper (so you don't have to rotate the stepper connector), and finally the decay mode of the current chopping on the motor drives. The decay mode affects the way the stepper motor controllers decays the current. Basically slow decay will give more of a hissing sound while standing still and fast decay will cause the steppers to be silent when stationary, but loud when stepping.
The microstepping_ settings is (2^x), so microstepping_x = 2 means 2^2 = 4. 3 is then 2^3 = 8. (One eighth to be precise)
Replicape Rev B
On Replicape Rev B, there are 8 levels of decay. Please consult the data sheet for TMC2100 on the different options.
There are three settings that are controlled on the TMC2100 by the decay mode or rather "chopper configuration": CFG0, CFG4 and CFG5 in the TMC2100 data sheet.
CFG0: Sets chopper off time (Duration of slow decay phase)
DIS - 140 Tclk (recommended, most universal choice)
EN - 236 Tclk (medium)
CFG4: Sets chopper hysteresis (Tuning of zero crossing precision)
DIS: (recommended most universal choice): low hysteresis with ≈4% of full scale current.
EN: high setting with ≈6% of full scale current at sense resistor.
CFG5: Sets chopper blank time ( Duration of blanking of switching spike )
Blank time (in number of clock cycles)
DIS - 16 (best performance for stealthChop)
EN - 24 (recommended, most universal choice)

Important note on the max current for a stepper: Never run the Replicape with the steppers running above 0.5A without cooling. Never exceed 1.2A of regular use either - the TMC2100 drivers aren't rated higher. If you need more current to drive two motors off the same stepper, use slave mode with a second driver (usually H). Yes, it means splitting off your wiring of the stepper motors you had going to a single driver, but it also means you avoid overheating your drivers.
If you want to enable slave mode for a stepper driver, meaning it will mirror the movements of another stepper motor exactly, you need to use "slave_h = Y" if you want the H-stepper motor to mirror the moves produced by the Y-stepper motor. Remember to also set the steps_pr_mm to the same value on the the motors mirroring each other, and also the direction. Most likley you will want the current to be the same as well.
- Enable the slave stepper driver (in_use_h = True)
- The syntax for selecting which axis is the master and which the slave is:
I want to slave H to Z (H follows everything Z does) then you use "slave_z = H".
- If you have any endstops acting on the master axis, then you should do the same thing for the slave axis, otherwise it will just keep on turning. For example, on a delta with Z1 connected to a bed probe and Z2 connected to the tower limit switch: "end_stop_Z1_stops = x_neg, y_neg, z_neg, h_neg" and "end_stop_Z2_stops = z_pos, h_pos".
# Stepper e is ext 1, h is ext 2 [Steppers] microstepping_x = 3 ... current_x = 0.5 ... # steps per mm: # Defined how many stepper full steps needed to move 1mm. # Do not factor in microstepping settings. # For example: If the axis will travel 10mm in one revolution and # angle per step in 1.8deg (200step/rev), steps_pr_mm is 20. steps_pr_mm_x = 4.0 ... backlash_x = 0.0 ... # Which steppers are enabled in_use_x = True ... # Set to -1 if axis is inverted direction_x = 1 ... # Set to True if slow decay mode is needed slow_decay_x = 0 ... # A stepper controller can operate in slave mode, # meaning that it will mirror the position of the # specified stepper. Typically, H will mirror Y or Z, # in the case of the former, write this: slave_h = Y. slave_x = ... # Stepper timout use_timeout = True timeout_seconds = 60
The accelleration profiles are trapezoidal, i.e. constant accelleration. One will probably see and hear a difference between Replicape/Redeem and the simpler 8 bit boards since all path segments are cut down to 0.1 mm on delta printers regardless of speed and there is also a better granularity on the stepper ticks, so you will never have quantized steps either. Further more, all calculations are done with floating point numbers, giving a better precision on calculations compared to 8 bit microcontrollers.
This section is concerned with how the path planner caches and paces the path segments before pushing them to the PRU for processing.
[Planner] # size of the path planning cache move_cache_size = 1024 # time to wait for buffer to fill, (ms) print_move_buffer_wait = 250 # if total buffered time gets below (min_buffered_move_time) then wait for (print_move_buffer_wait) before moving again, (ms) min_buffered_move_time = 100 # total buffered move time should not exceed this much (ms) max_buffered_move_time = 1000 # max segment length max_length = 0.001 acceleration_x = 0.5 ... max_jerk_x = 0.01 ... # Max speed for the steppers in m/s max_speed_x = 0.2 ... # Max speed for the steppers in m/s min_speed_x = 0.005 ... # When true, movements on the E axis (eg, G1, G92) will apply # to the active tool (similar to other firmwares). When false, # such movements will only apply to the E axis. e_axis_active = True
Replicape has three thermistor inputs and a Dallas one-wire input. Typically, the thermistor inputs are for high temperatures such as hot ends and heated beds, and the Dallas one-wire input is used for monitoring the cold end of a hot end, if you know what I mean... This section is used to connect a fan to one of the temperature probes, so for instance the fan on your extruder will start as soon as the temperature goes above 60 degrees. If you have a Dallas one-wire temperature probe connected on the board, it will show up as a file-like device in Linux under /sys/bus/w1/devices/. Find out the full path and place that in your local.cfg. All Dallas one-wire devices have a unique code, so yours will be different than what you see here.
[Cold-ends] # To use the DS18B20 temp sensors, connect them like this. # Enable by setting to True connect-ds18b20-0-fan-0 = False connect-ds18b20-1-fan-0 = False connect-ds18b20-0-fan-1 = False # This list is for connecting thermistors to fans, # so they are controlled automatically when reaching 60 degrees. connect-therm-E-fan-0 = False ... connect-therm-H-fan-1 = False ... add-fan-0-to-M106 = False ... # If you want coolers to # have a different 'keep' temp, list it here. cooler_0_target_temp = 60 # If you want the fan-thermistor connections to have a # different temperature: # therm-e-fan-0-target_temp = 70
The heater section controls the PID settings and which temperature lookup chart to use for the thermistor. If you do not find your thermistor in the chart, you can find the Steinhart-Hart coefficients from this online tool: http://www.thinksrs.com/downloads/programs/Therm%20Calc/NTCCalibrator/NTCcalculator.htm Some of the most common thermistor coefficients have already been implemented though, so you might find it here:

Below is what the configuration for the E looks like. The most important thing to change should be the sensor name matching the thermistor. The Kp, Ti and Td values will be set by the M303 auto-tune and the rest of the values are for advanced tuning or special cases.

With version 1.2.6 and beyond, the PID autotune algorithm is fairly stable. To run an auto-tune, use the M-code M303. You should see the hot-end or heated bed temperature oscillate for a few cycles before completing. To set temperature, number of oscillations, which hot end to calibrate etc, try running "M303?" or see the description of the M303 M-code.
Use this section to specify whether or not you have end stops on the different axes and how the end stop inputs on the board interacts with the steppers. The lookup mask is useful for the latter. In the default setup, the connector marked X1 is connected to the stepper on the X-axis. For CoreXY and H-bot this is different in that two steppers are denied movement in one direction, but allowed movement in the other direction given that one of the end stops has been hit.
Also of interest is the use of two different inputs for a single axis and direction. Imagine using one input to control the lower end of the Z-axis and a different input to probe the bed with G20/G30.
If you are not seeing any movement even though no end stop has been hit, try inverting the end stop.
See also this blog post and video for a more thorough explanation
Soft end stops
Soft end stops can be used to prevent the print head from moving beyond a specified point. For delta printers this is useful since they cannot have end stops preventing movement outside the build area.

Endstop troubleshooting advice
This was a short troubleshooting advice provided on Slack - it's being pasted here as-is until it can be rephrased and re-worked into the documentation properly:
Redeem basic endstop config! First and foremost make sure your endstops are working before trying to move. Now in redeem that is not quite as simple as you would expect. For these instructions make sure your bed is somewhere near the middle of its travel we do not want anything crashing into anything!
Go to your terminal in Octoprint and press your enstops with your finger one at a time you should get a response saying enstop # hit (# being what axis you just triggered) If you do not get a response Stop do not go further until you do get a resposnse!
Next go to your controls in octoprint and select 1mm and for Z press the UP arrow it should move 1mm away from bed for some printers with fixed beds that means usually the nozzle moves up! On others that have a bed that moves away from the nozzle because the nozzle is fixed in the Z plane it means the bed moves down!
We will stay with the Z axis now press the Z endstop and again try to move 1mm UP ( UP Arrow) if it does not move try moving the Z with the Down button it should move one or the other way this with tell you which way you have the endstop stopping movement.
For your particular printer and endstop location you need to edit the end_stop_Z1_stops = z_cw #stopping direction in a clockwise direction (I think you can use pos or neg as well) end_stop_Z1_stops = z_ccw #stopping direction in a counter clockwise
Soft Enstops You must have these set to outside your full travel in the min and the max soft_end_stop_min_z = -0.30 #300mm set to your printer travel plus some extra soft_end_stop_max_z = 0.30 #300mm you can configure to suit your requirements after! these settings are in METERS
If these are set wrong you will not move as expected you will not probe as expected!!!!
If you need to change direction of motors this is the line 1 or -1 direction_z = -1
The other Axis will be a similar procedure.
This section has to do with the speed of the homing and how much the stepper should back away for each axis to do fine search. Please note that there are two other variables in #Geometry section that are related to the homing routine: travel_* and offset_*. The offset_* values will move the print head immediately after homing, while the home_* settings found in this section can be used to set an offset to delta printers, so the head is kept by the end stops.
[Homing] # Homing speed for the steppers in m/s # Search to minimum ends by default. Negative value for searching to maximum ends. home_speed_x = 0.1 # homing backoff speed home_backoff_speed_x = 0.01 # homing backoff dist home_backoff_offset_x = 0.01 # Where should the printer goes after homing # home_* can be left undefined. It will stay at the end stop. # home_x = 0.0 # ...
Currently Redeem does not yet support tool offsets for dual or multi-extrusion. These offsets must be configured in the slicer, instead of in the firmware, for now.
You can control servos through Redeem and the way you do it is by using one of the left over channels on the PWM chip. A total of six channels are broken out through the expansion header named expand on Replicape A4A. Here is a list of the pins and which channel it is connected to:
- Pin 9 -> Channel 14
- Pin 8 -> Channel 15
- Pin 7 -> Channel 7
- Pin 5 -> Channel 11
- Pin 3 -> Channel 12
- Pin 1 -> Channel 13
The control signal is 3.3 V square waves which will probably not be sufficient to power larger servos without a level shifter, but some miniature servos can both be operated and powered with 3.3 V.
Servos are controlled by two on-chip PWMs and share connector with Endstop X2 and Y2.
- Servo 0 is on pin P9_14
- Servo 1 is on pin P9_16
Use G-code M280 to set the servo position. Note that multiple servos can be present, the init script will continue to initialize servos as long as there are higher indexes, so keep the indexes increasing for multiple servos.
[Servos] # For Rev B, servo is either P9_14 or P9_16. # Not enabled for now, just kept here for reference. # Angle init is the angle the servo is set to when redeem starts. # pulse min and max is the pulse with for min and max position, as always in SI unit Seconds. # So 0.001 is 1 ms. # Angle min and max is what angles those pulses correspond to. servo_0_enable = False servo_0_channel = P9_14 servo_0_angle_init = 90 servo_0_angle_min = -90 servo_0_angle_max = 90 servo_0_pulse_min = 0.001 servo_0_pulse_max = 0.002
Before attempting the configuration of a Z probe make sure your printer is moving in the right direction and that your hard endstops and your soft endstops are configured correctly please refer to the endstop section.
The standard configs for Z-probe should work for most. The real difficulty lies in making the macro for the whole probing procedure.
The offsets are the distance from the probe point to the nozzle.
Here are the standard values:
[Probe] length = 0.01 speed = 0.05 accel = 0.1 offset_x = 0.0 offset_y = 0.0
Hitwall's advice from slack
Z Probes are a great addition to the 3d printer! Having said that they do not take the place of careful initial manual config. For Delta printers they can be helpful for the calibration procedure but again they will not solve a badly built printer. I would suggest you should have your printer in a basic configured state.
First steps For a circular bed use : G29C #to create a macro for you( look at the wiki for details on it usage) M500 # to save to your local.cfg
For a rectangle bed use G29S # to create a macro for you( look at the wiki for details on it usage) M500 # to save to your local.cfg
Edit the local.cfg and add the appropriate G31 and G32 Macro.
G32 some Macro examples: G32 = M106 P2 S255 ; Turn on power to probe. G32 = M574 Z2 x_ccw,y_ccw,z_ccw ; enable Z2 endstop G32 = M280 P0 S-60 F3000 ; Probe down (Undock sled) G31 some Macro examples: G31 = M106 P2 S0 ; Turn off power to probe. G31= M574 Z2 ; disable Z2 endstop G31 = M280 P0 S320 F3000 ; Probe up (dock sled)
The same procedure as endstops First make sure your Z probe triggers the endstop Next make sure the Z probe stops motion (refer to endstop section for more detail.) Set your Z probe travel speed ...slow it down until your sure it works correctly. Test and happy probing!
Note: work in progress.
Meanwhile, see this blog post: http://www.thing-printer.com/filament-sensor-3d-printer-replicape/
[Rotary-encoders] enable-e = False event-e = /dev/input/event1 cpr-e = -360 diameter-e = 0.003

The watchdog is a time-out alarm that will kick in if the /dev/watchdog file is not written at least once pr. minute. This is a safety issue that will cause the BeagleBone to issue a hard reset if the Redeem daemon were to enter a faulty state and not be able to regulate the heater elements. For the watchdog to start, it requires the watchdog to be resettable, with the proper kernel command line: omap_wdt.nowayout=0
This should be left on at all time as a safety precauchion, but can be disabled for development purposes. This is not the same as the stepper watchdog which only disables the steppers.
[Watchdog] enable_watchdog = True
The macro-section contains macros. Duh. Right now, only G29, G31 and G32 has macro definitions and it's basically a set of other G-codes. To make a new macro, you need to also define the actual g-code file for it. That is beyond this wiki, but look at G29 in the repository, for instance: 
Tips: Each line in macros section needs to be spaced the same or you may not be able to connect in octoprint. Most Inductive sensors don't need probe type defined to work. To simply turn an inductive sensor on and off change the example macro with the g31/g32 macro's i have listed here. The g32 may need adjusting to match your z1 endstop settings. Undock turns probe on, Dock turns it off. Check your Macro and setup carefully, in the g29 example, at the end of each probe point it docks your probe then homes z before the start of the next point, which in some printers can crash your probe into the bed possibly causing damage.
- If you find that your probe routine is probing the air, your z axis is most likely moving in the wrong direction for the probing to work. It seems redeem only probes in one direction and this can't be changed in the probing settings. So, You will need to swap your z direction, in the [steppers] section using direction_z = -1 or direction_z = +1, then confirm your z stops/homing, ect work make corrections as required. You will also most likely need to change under [Geometry] travel_z direction. This should trick the probe into moving in the correct direction.

M561: Show, update or reset bed level matrix to identity
This cancels any bed-plane fitting as the result of probing (or anything else) and returns the machine to moving in the user's coordinate system.
Add 'S' to show the marix instead of resetting it.
Add 'U' to update the current matrix based on probe data
M562: Reset temperature fault.
Reset a temperature fault on heater/sensor If the priner has switched off and locked a heater because it has detected a fault, this will reset the fault condition and allow you to use the heater again. Obviously to be used with caution. If the fault persists it will lock out again after you have issued this command. P0 is the bed; P1 the first extruder, and so on.
M569: Set stepper direction
Set the direction for each axis. Use <axis><direction> for each of the axes you want.Axis is one of X, Y, Z, E, H, A, B, C and direction is 1 or -1Note: This will store the result in the local config and restart the path planner
M574: Set or get end stop config
If not tokens are given, return the current end stop config. To set the end stop config: This G-code takes one end stop, and one configuration where the configuration is which stepper motors to stop and the direction in which to stop it. Example: M574 X1 x_ccw This will cause the X axis to stop moving in the counter clock wise direction. Note that this recompiles and restarts the firmware
M608: Set stepper slave mode
Set stepper slave mode, making one stepper follow the other.
If no tokens are given, return the current setup
For each token, set the second argument as slave to the first
So M608 XY will set Y as a slave to X
If only the axis is given, no slave is set.
M665: Set delta arm calibration values

Makes the extruder interpret extrusion as absolute positions. This is the default in Redeem.
M83: Set the extruder mode to relative
Makes the extruder interpret extrusion values as relative positions.
M84: Set stepper in lowest current mode
Set each of the steppers with a token to the lowest possible current mode. This is similar to disable, but does not actually disable the stepper.
M906: Set stepper current in mA
Set the stepper current. Unit is mA. Typical use is 'M906 X400'.This sets the current to 0.4A on the X stepper motor driver.Can be set for multiple stepper motor drivers at once.
M907: Set stepper current in A
Set stepper current in A
M909: Set stepper microstepping settings
Example: M909 X3 Y5 Z2 E3Set the microstepping value foreach of the steppers. In Redeem this is implementedas 2^value, so M909 X2 sets microstepping to 2^2 = 4, M909 Y3 sets microstepping to 2^3 = 8 etc.
M910: Set stepper controller decay mode
Example: M910 X3 Y5 Z2 E3Set the decay mode foreach of the steppers. In Redeem this is implementedfor Replicape rev B as a combination of CFG0, CFG4, CFG5.A value between 0 and 7 is allowed, setting the three registers to the binary value represented by CFG0, CFG4, CFG5.
CFG0 is chopper off time, the duration of slow decay phase.
CFG4 is chopper hysteresis, the tuning of zero crossing precision.
CFG5 is the chopper blank time, the dureation of banking of switching spike.
Please refer to the data sheet for further details on the configs.
