How do I slow the rapid down? I tried searching the forum, but couldn’t find any XCP related topics on the matter.
My last project ended in disaster. Z plunged right into the table. The gcode looked fine. I don’t know if it was rapid related or if it was the $1=0 that caused it. I have it set to $1=255 now.
I would like to just slow the entire machine down to safe levels, but I don’t know the codes or the best settings. The default settings on most things are more than the machine can handle.
I’m guessing it had nothing to do with rapid.
The Z rapid is controlled via $112
The acceleration is controlled via $122
Here’s a good reference for understanding ALL of the machine’s Grbl Settings.
I installed a new 20 amp breaker and only the CNC runs on it. It’s like the machine is wired directly to the main panel with nothing else on the circuit. Should I still run a filtered UPS?
That’s way better. I decreased the rapid on XYZ by 50% and went with about a 25% decrease on the acceleration for XYZ. The machine feels less jerky now. I’ll carve something out tomorrow and see how it goes. Thank you!
What filtered UPS are you using?
Yes, I would. The separate breaker is nice, but you will still get feedback noise on the line. I plug the router directly into an outlet and then plug the controller into the UPS.
There’s 2 plugs on your xcarve pro? Hmm 
And depending on the filter method you might be turning a dive wave into a stepped square wave… 
APC RS 800, but I’m sure any filtered UPS will be fine. I had this one left over from a computer station no longer used. Basically inside the controller is an unprotected micro computer. Any electrical noise will disturb the program.
Correct - nothing to do with rapid. I was going slow and small cut trying to level the bed to the router, no hurry. I cut a variety of materials and adjust the speed depending on the material and bit size.
Additionally, keep the USB cable away from any power cords and use a good cable.
