Hi Simongts
How are you stopping and starting? Feedhold, Estop, cyclestart, jump to line?
Do you have a sample test file?
Did the method you are using work in the previous software version?
What is the previous software version?
What is the version you are updating to?
Are you using the G2 or G3? 3, 4 or 5 axis?
Can you share your printable settings file if you are using a G3?
Cheers Peter
