I have been updating a Boxford vmc260 which has been running mach3 with USS and PMDX125 in windows 7 for 12 years.
The machine is now configured keeping the PMDX125 but changing to ESS and Mach4 in windows11. Having worked through getting tool change and probing working it was time to try running a simple program to drill a couple of holes centre drilling first to test the tool change.
After setting work coordinates and running the Gcode the machine carried out the tool change, started spindle (which is an ac servo set up as motor 5 step and direction) and immediately froze.
If you turn spindle off from the screen and back on again until the gcode reaches M05 and it pauses again.

I have stripped the gcode back to 2 lines:
S2000 m03
G90 G00 x25 y25
Run from MDI spindle starts but moves are not executed.
If I remove the S2000 m03 the move does work so it has to be due to the spindle command.
I have disabled ‘wait on spindle to stabilise in Control Spindle tab.
Mach4 V4.2.0.4809 licensed

Has anyone come across this or have any idea where I am going wrong?

Regards

This is the diagnostic log that shows waiting for 200 seconds (not sure where this comes from and also mentions laser

Problem found ignore all of above I cant figure out how to delete it.
a delay of 200 seconds in acceleration and deceleration was the problem
