Dual Z stuttery mess, single z fine



  • Hello all, I appreciate any help with this. Tried to add to another thread about this but it was locked.

    Using just one Z output/jumpers the stepper works just fine, but using dual Z the movement is stuttered, loud and slow. Either Z stepper plugged into E,X,Y work correctly as well.

    Tried using the suggestion in the other thread of using E1 for the second Z stepper using below code "before any M350 / M906 commands". M584 X0 G1 S2:4 E3
    No motor movement after adding to config.g

    I've tried both with/without a M569 P4 S0 command

    would that not be M584 X0 Y1 Z2:4 E3

    Unbelivable that you didnt read this befor adding command to config.



  • @veti
    Thanks, that's the trouble with only being able to spend 20-30 min in the middle of the night trying to troubleshoot. Simple stuff slips by

    Some people might also find it unbelievable that you cannot spell unbelievable ☺ Come to that, "didnt" should be "didn't" with an apostrophe and "befor" has an "e" on the end. Which just goes to show that, unbelievably as it may seem, we can all make mistakes ☺



  • Yes, sorry for my comments, i sholdnt say like that. About my language - english is not my first language, so still learning and making alot of mistakes with it. At least i hope we can understand each other somehow.
