glad to hear that you figured it out.

if you what to share your Project (arduino THC) it will be great.

vital Systems or CSLab offer Motion Controller for servos (+-10V and Encoder  Feedback) or also EtherCat.
but nearly all servo Controllers can also run in step/dir mode (open Loop).

i think we have to wait until one of the lathe guys can help, my knowledge in lathe will be to less.

important is, that X-axis DRO is getting smaller if tool is moving to Center of spindle.

Motors are tuned to 6400 steps/ and velocity of 200 with pulse of 5/5 using 1/2-10 5 start lead screws.

that means your Motors are set to 3200Steps/rev.
i would try to half (1600) this and test.
for test run a simple G_code for one axis like:

Code: [Select]

F20
G1 X10
G1 X0
G1 X10
G1 X0
G1 X10
G1 X0
G1 X10
G1 X0
G1 X10
G1 X0
M30

and have a look. also reducing the acceleration might help.
how are the step/dir signal's  wired?

softlimits are allways based to machine coords. so Switch to achine coords to check the values.

Mach3 under Vista / Re: Setting up mach 3 on good used cpu win7

« on: April 11, 2021, 05:49:47 AM »

some more Information about the breakoutboard would be good.

about the Profile XML file, there should be a file named Plasma.xml in your c:\mach3 Folder.

-are Motors wired Serial or parallel ?
-is the Setting for Motor current adjusted on the m542 to the Motor current from Motor datasheet?
-is the microstepping set correct corresponding to your step/per Setting?

when you get your Pictures uploaded pls. also add your Profile .XML file so we can have a look. without your Pictures of wiring
and to identify your components ist very hard to help.

ob es in Mach4 was gibt, kann ich nicht sagen, da ich es nie benutzt habe.

there are several posibilties to do that.

1st modify your postprocessor to make a G31 and the commands to lift Z-Axis before every Torch On (M3)
2nd modify your M3 macro so it does the G31 and commnds to lift z-axis before fireing torch
