HI all.  Running a laser with Mach3.  Yesterday I was cutting a PCB and hit feed hold to check something with the laser.  Mach3 stopped as it should, I did my checks and then hit Start.  As soon as I hit start, Mach3 reversed, then did a big circle on the PCB, circling back to the starting point then continued on as normal.  Needless to say, a ton of money went down the drain. 

I've used Feed Hold before with no issues.  Do I need to restart, reboot each time I use Mach3?  Any idea?

Thanks,  Pete

That did the same to me I was using the mill a circle pocket to check my servos and hit feed hold and when I restarted it  the tool path went  in reverse.

I hit feed hold again and it started up in the right direction.

Sorry I didn't answer your question but your not the only person who seen this.
