Its happened 3 times so far, (for I figured out what was going on) and lucky me no valuable work screwed up. Fine Line Automation Saturn 2 the newest one out. Mach3 licensed, ESS controller installed in the prewired control box and seems to work fine. I have ran some pretty complex g code files out of VCarve Pro 9.5.

So here is the issue, running a file starting out and I decide whoops thats not right, Stop raise Z, rezero and rewind the file. Restart from Line 1, and it goes and tries to run from the last place the reset file was at!! The cursor in Mach3 does not show it at that line. Remember I restarted the file from line 1.

So is this just the way it is in Mach3, just exit the file completely and restart Mach3?

OR is it the buffer in the ESS not being cleared out? If it is a buffer thing how do I clear??

Or just do what Gary suggested, go to the ACORN? If so I will need to bite the bullet and get Windows 10 Pro to run the program.
