Poor Axis Performance run g-code
« on: May 22, 2015, 04:39:54 PM »
I am creating a automated machine to help in the production of some lights we manufacture.  I am using Mach 3 to control a 3 axis table but i am having trouble getting the axis to run smoothly when i run actual g-code.  I have tuned the motors using the suggest motor tuning in Mach 3 and they work perfectly when i just manually move the all axis's.  Has any one ever seen this issue before.  I must admit i am not the most experienced at this stuff!

My machine hardware
Drivers: DM524 on all axis
Controller: USB XHC 6 axis made by cdhctech.com
Steppers: 23HS2430B 1.8 Deg 3 Amp
I have Steps per at 80, velocity at 2500 and Acc. at 750

Thanks
Scott

Are your tool paths lots of short arcs or line segments? If they are and you have full stop mode selected the motion will stutter as the axis start and stop at the end of every segment. Use constant velocity contouring instead and Mach 3 will keep moving as smoothly as it can.

I am new to g-code mode commands but i believe G64 is listed on top of screen in Mach3.  I used the wizard to create the code to simulate cutting a 100mm radius circle for my test.  Is there something else I am missing?

Thank you for you help!
