I have a recurring problem, where the torch signal is not sent anymore on screen indicator stops working and the machine keeps running. Closing and reopening Mach usually fixes it, but we are always mid way though a sheet when it happens. Happens a few times a day.

Anyone have any idea on where to check first?

We are running windows XP, Candcnc DTCHIV Parallel port, Powermax 85.

Usually if we have show tool path off it does not do this, but I have been running mach for years without this issue.
