SmartBOB controllers and dedicated accessories / Squaring the Gantry on the PMDX-424 without functionality
« on: August 06, 2020, 11:32:21 AM »
I'm attempting to find a solution to squaring the gantry on a AVID CNC CRP4824. The 424 does not have a gantry squaring feature so I have thought of two options:
1. Using LUA I would have to un-map the two Y stepper motors Y1, and Y2, Move them both to Y home waiting for both proximity sensors to trip and then once this is complete, establish a machine home and re-map the two motors back to the Y axis. Am I missing anything?
2. (Current method) where I move the axis manually to a known alignment fixture. This is only an eyeball method and works "okay" now.
Does anyone have any better methods? I'm digging into the LUA code base and it could take some time to get a working script.
Thank you
