No Z-Axis but still getting Joint 2 follow error was created by hatch789
Hi Guys, long ago I was helped with my LinuxCNC setup. The machine I use only has X & Y servos and no Z control (right now). One day I figured I might try to add the Z axis to it but that remains to be seen.
The reason for my post is that I'm still getting a "Joint 2 follow error" even though my Z axis is fully commented out in the TREE.INI file for my machine.
I would like to know if there's a way to eliminate follow errors or just make the Z allowance so large that I never get a follow error on that axis.

You can try to setin the ini file.
[TRAJ]
AXES = 2
COORDINATES = X Y

I can try that but I'm curious how the SIM-AXIS machine does it for all 3 XYZ axis? It works so well for this simulated machine that's kind of what I'd like to do for my Z axis. See it changing numbers but not give any errors.

You can do this by looping back the commanded position to the feedback position,
something like this:
net z-pos-cmd-and-fb <= axis.2.motor-pos-cmd => axis.2.motor-pos-fb
something like this:
net z-pos-cmd-and-fb <= axis.2.motor-pos-cmd => axis.2.motor-pos-fb
