Z+ Skipping with weight of router

[danc]

Hi,


I've assembled my M3 kit and everything seems to work, with the exception of the Z+ axis.  


The axis works without the weight of the router but pulses or skips when trying to lift the weight of the router in the Z+ direction.  Things seem to be fine in the x, y, and z- directions.  It also seems to have an issue with the pressure exerted by the spring at the z+ extreme.


I've tightened the belt and the set screws on the motor.  I haven't rechecked the voltage yet, but am reasonably sure it was close to .6v.


Any suggestions on what else may cause this and how to resolve?  


Thanks in advance for the help,


Dan

by skipping or pulsing I mean the router is lifted up 2-5mm and then fall back down.

Double check you driver voltage settings. Some people have mistakenly set theirs for 0.06V instead of 0.6V. Maybe this is more likely to happen with the cheap voltmeters that aren't autoranging, and it's easy to mess up the decimal point.

Hey.

Rowiac’s suggestion is a good one. 50% of the time on this particular system when the pulley and belt are correct and the motor won’t achieve position it’s the driver setting. I would also like to confirm that you have the jumpers set underneath the driver and that you have the right settings. Please type $$ in the command line and press enter. Copy and paste the settings here and I’ll have a look.

Thanks very much - I did indeed misread an analog multimeter and had things at .06v. Sorted, and seems to be working well. I appreciate the help.

Awesome. Glad all is well.
