General Mach Discussion / Re: Intermittent movement along toolpath
« on: February 09, 2008, 01:50:03 PM »
Hood!

Just hooked up some steppers. And they're moving exactly as the crosshairs on the screen I've tried to cut a simple circle and it's moving along in 3-5 mm steps accelerating/decelerating all the time ending up with maybe 20-30 green dots along the contour on the job screen. Tried the G64 as well just doesn't do it.
I'm running mach3 (35kHz Pulse) on a dedicated 3.0GHz CPU with 4GB of RAM can't really go higher then that. Tried higher acceleration, read something about that, but just makes the whole affair a bit crisper. It just looks like im allways in Exact Stop Mode yet if got G64 on.
Just stumps me man.

General Mach Discussion / Intermittent movement along toolpath

Hi folks,

I'm sorry to warm up a old topic but I have not been able to find a suitable answer despite rooting through the forum.
I'm just in the process of refitting an Aciera F5 kneemill and I'm trying to get to know Mach3 without havin any harware hooked up.
Question is, when I run for example the roadrunner file or any old G-code for that matter, the tool is not moving along in a reasonably smooth fashion, rather it runs along a short stretch and stopps then starts again and so on.  Now when I look at Art's tutorial video his job seems to be cut in a smooth continous movement. I've tried fiddling with the CV-,Speed- and Accs  settings but it doesn't really seem to make much difference at all.
Sure somebody has an easy solution for that one.

Dave
