It shows the real bones of the machine.

Auto calibration is the dream. I’m planning on big beads a fixed distance from the gondola and a calibration on startup that winds in each spool until the beads hit a switch. I’m going for cheapness rather than elegance. I would like to be able to do proper width calibration too, but I think simple measurement for that one is probably enough.

Just adapt your drawbot to use the same coordinate system as the gcode. By all means, go ahead and use the software. If you can help me with pen up/down that would be awesome! I’m also looking to auto-calibrate. If you or one of your readers is interested, please come check out my website and say hello.
