Axis reverse
« on: July 15, 2020, 05:49:45 PM »
I have a Harbor Freight Mini-Mill that I converted to a 3-axis CNC machine using a Heavy Metal ball screw conversion kit with Automated Technologies electronics. I use Fusion 360 for design and have installed the Mach4 post to my local library from Autodesk's website. I have made a small bottle opener to test. Every time I run g-code the part comes out mirrored. My y-axis seems to be inverted. When the y-axis is supposed to be traveling in the y- direction it travels in the y+ and visa versa.

It is easy enough to change the direction of your Y axis - Just change the direction pin output for that axis from active high to active low (or opposite to this if it's already active low) - this is in the pins setting of your motion controller configuration.

Already tried that with no luck. I just reversed the wiring. That seemed to do the trick.
