E-Stop After Zeroing an Axis
« on: November 24, 2009, 11:17:35 AM »
Sometimes when I click zero for the X or Y axis, the machine goes into e-stop. Does not happen every time. I'd prefer it to not go into e-stop. Any suggestions?

I am running a SmoothStepper in case that makes any difference.

You need to provide a lot more information. What type of drives? Does the machine look/sound any different when the EStop happens? How are your home/limit switches connected?
Happy machining , Jeff Birt

Are you meaning the Zero button at the side of the Axis DROs? If yes then that is really weird and I dont see how that could be happening as all that does is zero the work offset and does not do anything electrical.

Yes, those are the zero buttons I am using. It just hit me that I may be the culprit. I have a Mach Brain that monitors encoders on the y and the slaved y-axis and issues an e-stop if they differ by more than a pre-defined amount. Perhaps the Brain is firing. However, I am pretty certain this also happens with the X-axis which should have nothing to do with the Brain. I'll disable the brain and see if the problem goes away.

Thanks,
