It appears G10 L2 and G10 L20 assume machine is actually Homed physically, and no amount of data entry can change that.

I don't understand what you are doing. Without homing the machine first there is really no point in setting offsets.

Hello everyone,

I have a strange problem with LinuxCNC on a machine that has been configured for a long time and was working perfectly.

Until a few days ago, everything was working fine. Then I modified my Python Touchy GUI file (adding dynamic multi-language translation using `set_label` on some buttons), and from that moment the problem appeared:

> "joint 0 following error" immediately after clicking "Start".

The problem still remains even if I completely delete all the translation modifications (`LABELS` and `on_combo_language_changed`);


Code I had added:

LABELS = {

@cakeslob , I had a look at your hal file again and copied your spindle stuff exactly just changed for my pins etc and it's still the same. So I think that rules out a hal file problem. I don't think it's the vfd because I can change the speed manually by pressing the + and - manually in the  Axis GUI and it responses quick with no dips when changing speeds.
