Mach4 General Discussion / Shift Z-axis workshift with scale on knee

« on: November 01, 2021, 03:46:54 PM »

Hello,

I have a three axis knee mill retrofitted with Mach4.  The Z-axis is on the quill and has only 5" of travel.

What I would like to do is use the scale that is on the knee (already interfaced to the DSPMC) to update the work shift when it is moved that way as the table is moved up and down the work offsets are still relevent.

The scale is interfaced to scale 6 of the DSPMC, what would be the most robust way to have it update the workshift when moved?

dspMC/IP Motion Controller / Motor tuned well in dspMC plugin but not when commanded by Mach4

I have tuned my axis well in the dspMC plugin and the test motion is very smooth and stable but when I command a move from Mach4 either jogging or g-code the axis has a considerable studder, the machine shakes and will trip on following error.

I have used the same max velocity and acceleration settings on Mach4 as the dspMC plugin and even tried adjusting these settings in M4 very dramatically but to no avail.
