I was wondering if anyone has experienced a jumpy axis on a router table that was caused by the Motor Tuning in Mach.
Could a miss tuned motor somehow cause a slight jumping effect that is more pronounced with faster speeds?
I am pretty sure there is nothing with the gears or Nema 34 motor. It just seems as if there is a possible internal fight happening, but I could be crazy as well.
I am not losing steps nor is there any kind of noise, but you can see the table shake slightly.
The noticeable shake is at a speed of say around 120ipm but if you slow down to around 60-80ipm it is a lot smoother.
Hi,
if its not losing steps, it sounds like it close to doing so. I would guess its a mid-band resonance. 34 size steppers seem to be prone to this kind of vibration.
Hi Craig,
I figured somebody might have some great info on this forum. It is very odd, but I did notice something tonight as I was changing tools, I use my remote pendant or arrow keys and it is moving as smooth as a baby bottom.
I will also say I am noticing this more on 3d/STL type carvings like a waving flag type carve. I took a screen shot of the motor steps. Y is very similar but doesn't seem to be jumping.
Do you think I am off on the steps or maybe the velocity is to high?
Im using surestep motors and Automation drives.
