I wrote support about this, but thought I’d post it here as well, while I wait for a reply.
Yesterday when I powered on my machine, before I got around to initializing it from Carbide Motion, it started making a knocking sound. After looking/feeling around I located it coming from the right-side y-axis stepper-motor. I’ve looked for loose connections and tried powering it off over-night, but no luck.
Did some more troubleshooting and when switching the Y1 and Y2 connectors on the controller the problem moved from right-hand side stepper-motor to left-hand side indicating a problem with the controller.
Thought I’d update this post in case someone experiences the same in the future.
Interesting. I have the same noise, but only when moving. I literally took a video yesterday in hope of reaching out to support to see if it’s normal. It’s on a SO PRO XL
I’m not able to use my machine at all. I tried to initialize my machine once to see if it was just a warm-up problem, but had to shut down the machine immediately as very bad noises were coming from the stepper. Only tried it once as I don’t expect a different result and don’t want to damage more parts.
