Need advice for "smoothing" motion during sequential small arcs.
« on: December 01, 2008, 06:45:12 PM »
Running Mach3 to a Vortech router. (Stepper motors)

 Straight cuts, circles and arcs all cut pretty decent, but compound curves (most of my work) cut painfully slow and "jerky".

Converting compound curvess to arcs and tangent line segments speeds the process up, but with hundreds of segments, the acceleration and deceleration appear to be applied to each and every segment in spite of continuity.

I have done some trial and errror setting accel and decel, but with no apparent affect.

I have also tried CV mode with no apparent value.

I suspect I am just overlooking something simple. Any and all suggestions appreciated.

Thanks in advance, Carver

Hey, don't get Phill too good at this CNC stuff as he may just give up the mallet and carving tools .....thus another good artisan will have gone over to the dark  >:D side of the craft. 
Liked the work on you site, Phill
