Interesting one here - Checked simulation and it shows a milling plunge to Z0followed by a ramp down across the first span then flat mill as I want, around and around to the finish. Punch it through a Mach3 inc Post and input the txt file into Mach3 to create part and the ramping moves have changed to plunge to Z0 followed by cut then another plunge to Z-1 to mill the remaining contour?
Don't understand how / why it drops the Z move down to a seperate line?
I've attached the cad / cam & .txt G Code files - anyone have a guess?
Tried sending to Michael @ Dolphin but no word as yet (over a week now)
