Hi All.
I’m a CNC / Chilipeppr newbie, but have a good deal of physical computing / general technology experience.
I’m working in the Sculpture Department @ the Milwaukee Institute of Art and Design, and we recently were given an old small CNC from Isel-Automation.
I’ve removed the old controller board, and replaced it with a TinyG, and have been playing around with Chilipeppr. All is going well enough, aside from an odd issue with the X axis. The jog controls are reversed. If I instruct Chilipeppr to jog left, the machine moves right. If I try to home the machine the X axis moves away from the limit switch. (Y and Z are fine).
However, the files cut in the correct orientation. If I reverse the polarity of the X stepper, the machine homes and jogs correctly, but the cuts are reversed on the x-axis (mirror image).
In all instances, the simulator works fine. I’m running firmware build 440.20.
I’ve tried the Chilipeppr logo file and a file generated with JSCut. Both behave exactly the same.
Everything I’ve read suggests I reverse the polarity, which I’ve done, but that doesn’t solve my homing problem.
Any thoughts?
