Any reset would probably do that. I assume you are pressing it out of sequence. Some controllers monitor these inputs (most grbl seem to) for ANY activity and halt the machine. So if I’m understanding you, it’s probably normal.
You might have to check with the manufacturer to see if resetting these values is the default operation of that machines controller. I know at least one manufacturer resets many of the control registers you need to change. Bad idea…
I’m sure there are firmware upgrades, but don’t know your machine so I really can’t advise you about much along those lines. You usually lose your warranty coverage.
If you don’t mind… There is another Sculpin user that is having issues… Maybe you can help, they are looking for another user of the same type of machine… At least ‘hook’ up, maybe you can help each other out…
I’ll drop this link over there also…
Good luck
Take care
