This is the xml.file. I copied it without renaming it. Really curious if you find something! Many thanks in advance

"Go to Zero" is a system function within Mach3.
I do not see any issues with your XML and it responds normally here.
Perhaps it is associated with your "Xulifeng-Mach3-USB-Motion-Card", assuming there is a plugin for it.

Looks good here otherwise.

Thank you! Do you think it is plugin related or hardwarerelated? As mentioned , maybe my old plasmacutter with HF ignition damaged the Xulifeng? Still weird that running a g-code works normal and so do the arrow keys.

 can buy a fairly cheap second hand nvum mach 3 controller. Maybe it's wise to replace the xulifeng by that one?

Hi,
when Mach starts it defaults to a low 6% of max speed.
Craig
.... actually, it defaults to 6.00 units per min.
Inches would be quite "visible", but mm's would barely creep.
Increase override 200% and that DRO goes to 12  :)

What is showing in the attached pic while your machine is invisibly moving after hitting the "Go to Zero" button ?

The set feedrate is 1000
Units/min runs between 9000 and 10000
Units/rev is 0

I really really don't know what i have done but it seems to work fine now.... Maybe I hit the button softlimits but I cannot imagine that did the trick.

I have to come back to that. As I tried to Ref all Home at a better point on the table and moved evetything afterwards the same problem occurs. I dod ref all home and moved the X and Y in the max position. Pressed.go to zero and it was slow again. to

I think I figured it out! Each time I change the Ref all Home point on the table, the machine has to run one pass to that point in a very slow mode. Once finished, from that moment on it moves fast and normal.

Can anyone confirm this is normal?
