I built a new, slightly smaller and lighter sled for my machine. Installed it, and ran through the calibration the first time. During the test cut, everything stopped between the 2nd cut and 3rd cut. No errors, messages or anything.
I shut everything down, the computer, maslow, everything. Powered everything back on, ran the calibration again, but now, the 2nd cut is “curvy”. (I stop it after the 2nd cut, so I don’t know what cut 3-4 look like) It looks like it’s lowering the Z a little too soon, and once it starts cutting, the curves.
Here’s the part that really worries me… I smell a faint “electrical” burn smell… At first I thought it might be the Z axis motor, since I kept hearing a squeaky noise when adjusting the Z - initially, I thought it was just the screw drive/rails, which I lubed (seemed to help, but didn’t go away)
But now I’m worried it’s the shield. Looks like the one I have (two processors with stick-on heatsinks) has a tendency to burn up. I’ve yet to get on a ladder and put my nose up to the controller.
Does this sound like it could be the controller?
