My Lead 1010 worked flawlessly for over 8 hours of milling but now the Z stepper motor stop homing

    I got my Leas 1010 bundle last week and built the unit over the weekend. I then went through all the calibrations and setup and all was well. I then built one of my Ultimate Barbecue Cutting Boards and the machine ran perfectly. I shipped out the board yesterday. Now my issue. The machine started getting some errors when I ran the flattening program.

    Then it just stopped homing and the Z stepper now just growls and cannot go up and just down. Here is a video of the problem.



    I have a 7 Ultimate Barbecue Cutting Board backlog for Christmas. My plan is to get them all out by this weekend. The board is big and complex so it takes hours for the machine to mill the board.

    If you can help me with this for I need to get back to production. I was going to do a complete video on how I use the Lead 1010 to build my boards but can only do that if it is working.

    Appreciate your help.

    Error 9 would come after some alarm. Probably alarmed because homing failed due to the motor not working
    Motor - from your video - looks like the classic symptom of only 3 of the 4 wires making good contact: See docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation]
    "Wiring is always fine until it isn't anymore" :) - things move and pull and tug and vibrate. Screws can rattle loose, wires can break. Redo all joints on that motor's wiring, or measure with a Multimeter from each end of the wire to find the break.

    NB: power off controller before connecting/disconnecting motor wiring!

    Peter,

    I just metered all 4 lines to the stepper and the blue wire is open but not at the plug but the wire itself is open. Now I have to go find some wire in town and replace the wire. Because it is the longest wire in the machine I am just going to buy a single wire and run in parallel to the other wire. I very much appreciate the fast response. Now I can get back on track and make some customers happy.

    Thanks,

    Fred Wiley Richardson

    I figured about time we also remove this confusing aspect of Grbl - always hard to help troubleshoot :)

    v1.0.266 coming out soon will now remember what the earlier alarm was, and include that detail for "error 9" error messages to avoid users having to look back at the log to see the history that led up to the error:

    I had the exact same issue but it was the green wire in my case. I think I ran the wires a bit too tight on my high z mod 1010 where you transition into the cable chain on the Y axis and cause a break. I just ended up ordering some more wire and rerunning it. No problems since then but was of course mid job when it decided to yeet itself into the waste board.
