Hello Balazs!
I am notice this issue.
I am open cutting program. Click on the START button - torch move to the first cutting path and wait for ArcOK signal. THC ON.
If I am click on the STOP button and then back to START button, SpindleCW command on M3 is not performed and torch not wait for ArcOK signal and move along the cutting path.
This issue only on the first cutting path of the program. On the remaining cuts all is OK.
