Motors stall when using Goto Z's
« on: November 12, 2011, 09:57:43 PM »
I've been using my mill at lower speeds for awhile and decided to see if I can increase the speeds. The problem I am having is that I can go up to 45 IPM when I use the keyboard without issue, but when I hit GOTO Z's, it will stall the motor (as it ramps up to the desired speed). I've tried several acceleration numbers that seem to make no difference. I can lower the IPM back down to <20, but that's boring! Anyone have any idea why GOTO Z's would be different than keyboard pendant control and what I could do to potentially get this working at 45 IPM? Thanks for any help!

When you are jogging are you only moving one axis at a time? If so then could be your power supply is not quite up to it when moving multiple axis.

I'm only using one axis when jogging. The same goes with when I use the goto z's. I've only moved it away from zero on one axis.

I finally had a little time to try that out. When holding the shift key, jogging the axis has no problems. It runs easily up to 45 IPM. Any other ideas as to why the goto z is different?

If you attach your xml I will see if I can replicate here and maybe find the issue.

Try using the demo version. The one you are using is not supported. >:(

Had another look and  xml looks fine, just wondering however if it has anything to do withyour A Axis, can you disable the A in Ports and Pins and see if there is still a problem.
