I have a CNC converted mill from International Hobbies. It is one like Charter Oak does now. I think it is called a column mill. It has been a pretty good and useful mill. I'm running Mach 3, still using a parallel port. It is a pretty fast computer running Windows XP. At times, I just need to do some simple operation and I try to use the MPG (manual pulse generator) pendant to do an axis move. The MPG is set up for 1X, 10X and 100X motion which can be selected. If I move at 1X, I can get smooth axis motion, but really slow. If I select 10X or 100X, the motion is jerky, like the software catches up, then pauses, etc.. Is there some setting in Mach 3 where it will provide some ability of moving the axis faster but smoother with an MPG? I don't want to change anything that makes the CNC control change as it works well now. I know moves can be entered in Mach but I'm just wondering if I can make the MPG more useful for simple cuts. Would external hardware like an ethernet smoothstepper help with this?
