Looks like you are almost there Barry. Can't wait to see pics of the stuff you make with your wonderful machine.

btw. That lab is far too clean and tidy. If I worked there I could fix that in a couple of days.

I used to have a similar problem cutting lithophanes which have large files (320,000 or more lines of code) and found that the issue was related to a refresh of the LPT port. I never did discover if this was a Mach related or computer related thing but my cure was to reconfigure my limit switches and e-stop to 'push to make'. Not everybody will agree with this strategy but it worked for me.

I think it's an optical illusion Barry - you don't get to see the stuff that goes in the bin.

It would be helpful if you could provide more details.

Was anything shown in the Status box after the stop ?
Was it an e-stop or limit switch triggered (Reset flashing) ?
