Z Axis initialize doesn't work

When I try to initialize the machine, the router goes up all the way and just makes a rumbling noise. What should I do? I’d say about 1 in 40 times it gets past this and works, if I shut the machine down after it actually works, same thing happens again next time I go to use it. I have the z axis homing switch all the way to the top and I can see the router actually hitting it and moving it up a slight amount

Sounds like an intermittent with the Z sensor. If you have a spare, swap that in.

Otherwise, check the wiring, especially at the connectors, and where the wiring connects to the controller board.

New machine just assembled? Or machine which was working which has developed a problem?

Photo of the machine and its Z-axis and video showing what is happening?

did you get the email from my gmail account, i attached a couple of pictures and a short video. I can’t attach any pics on this forum.

If you’ve mailed in to support, we’ll yield to the folks there.
