Well I've had a crap day with the uc400 and uccnc today. Mashed up two pieces of stock when uccnc failed to stop at the coordinate and dro continued on. Have run the program many times with uc300 and uc400 and it runs fine.
Funny never once had this issue with the usb uc300.
Got to be software issue right if the dro continued.
The line both occasions was diffrent and both were simple X y moves.
Hope uccnc is now not another cnc control software that corrupts itself like Mach 3. Without swearing I could not explain how I feel right now.
