I have a visable wobble, which prob equates to about 0.5-1mm of runout on my y axis. If I loosen the step motor a little from its mounts you can see the motor wriggling as the ballscrew turns.
I bought the router as a pre built kit, the only part I did myself was wire up the electronics. As the machine is still under warrenty Im a little nervous about removing the ballscrew to check to see if the runout is only in the machine section of the screw.
Would runout be a potential cause of my motor stalling? The manufacture assures me with my setup I should be able to go as high as 7m/min yet I cant go much higher than 2m/min without the motor stalling.
Current is set as high as possible 3amps and the micro stepping is as per the manufactures suggestions.
Slowing the acceration appear to have no effect on the motor stalls.
Cheers
