Redeem version 2.1.1
OK, so you're wanting to set up your shiny new Replicape and get printing, but you can't make heads or tails of the configuration. Never fear (well, maybe fear just a little, but bear with me..), this will walk you through generating your local.cfg to hopefully get you running. If if have questions, feel free to come over to the Slack channel and ask for help.
This page is also assuming you've read through the Printer 101 page.
Your Redeem local.cfg handles the basic configuration for the system. Redeem will look for a needed option in the local.cfg first, and if it doesn't find it there, will look in printer.cfg (if you have it set), or default.cfg, in that order. Any time you change your local.cfg, you'll need to restart Redeem.
You can edit the file either through the Octoprint interface, or if you're linux-savvy, at the command line. The file is located at
Any time you add a section to your local.cfg, you do need the section header, which is in brackets.
Your local.cfg may have only a few entries, or it may have nearly every entry listed here. It's strongly recommended to use local.cfg instead of modifying your printer.cfg or default.cfg, as those may be overwritten during an upgrade. local.cfg will never be overwritten, unless you completely wire the BeagleBone and reload the system.
The first section is System related. For the most part, you don't need this in your local.cfg, as the values probably won't need to be changed.
[System] # CRITICAL=50, # ERROR=40, # WARNING=30, INFO=20, DEBUG=10, NOTSET=0 Very seldom will this need changed. 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 # location to look for data files (temperature charts, etc) data_path = /etc/redeem # 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
Next up is the printer geometry. You'll define dimensions of the print volume, directions, and end stop locations here. You probably won't need all axis entries here, so just use the ones you do need (X/Y/Z/E and possibly H usually). A/B/C axis are included in case you're running a Reach board on your Replicape.
[Geometry] # Select which type of printer you have here # 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. # This is not the print volume dimensions, but how far to travel when searching for an endstop. # Safe values would be your bed dimension for the axis plus 10mm or 20mm # Remember, all measurements are in meters travel_x = 0.2 travel_y = 0.2 travel_z = 0.2 travel_e = 0.2 travel_h = 0.2 travel_a = 0.0 travel_b = 0.0 travel_c = 0.0 # Define the origin in relation to the endstops. # Origin is usually the Left Front of the print bed, or in the Center for a Delta. # 0.0 tells the system that your limit switch for that access is at the minimum (zero) end of travel. # If you have the limit switch at the maximum end of travel, you need to tell Redeem how far 0.0 is away on that axis # For example, if your X axis has the end stop at max travel, you would use offset_x = -0.300 # to tell the system that 0,0 is 300mm away. # Note the negative in the above example... this tells the system to go back once it homes on X, instead # of trying to continue heading right offset_x = 0.0 offset_y = 0.0 offset_z = 0.0 offset_e = 0.0 offset_h = 0.0 offset_a = 0.0 offset_b = 0.0 offset_c = 0.0 #This is for bed leveling.
