Hi

I'm using modbus to control my Huanyang VFD and I use the scripts for M3, M4 and M5 from your blog. The problem is that when I load a .nc file i get the message 'Warning: LoopLimitCount=2' and the toolpath is not displayed. The .nc program runs as normal.
If I remove the script for M3 it works as normal, no warning message and the toolpath is displayed.

When g-code is loaded for display it goes into endless loop. You should modify your scripts to prevent this.
Use ACTIVE[] function
https://cnc.zone/gcode/functions/func-active
to detect if g-code is actively controlling machine.
For example default M3 script uses this code:

o<chk> if[LNOT[ACTIVE[]]]
  M99
o<chk> endif

to exit script af g-code is running for display only.

Where should this code be inserted into the script? I have the same issues with the MODBUS. Get the loopcount warning/error and can no longer see the image of what I’m cutting on the screen. Or has the MODBUS script been updated with this?
