Hi to all. I have used the files attached interpcnc.iso (pcb project) in Mach3. But the execution is not fluid but intermittent and the padses are not sometimes aligned. The option Constant velocity in the menu Config | State is selected. The same files executed with Ninos 3.1 it is perfect. I prefer to use Mach3. Do you have a remedy? Thanks in advance. Giordano

CV Will not work in the file that you have posted... The G00 moves are not CV moves only G01,G02 and G03 moves. I have shown an example of your file so you can see all the G00's. I think if you changed them to G01's you would be VERY happy
