New XZmotors problem
-
Hi,
Duet 2 WiFi board, I changed XZ motors, CoreXZ printer, and started having issues with X movement staggering at higher speeds.
Video of the problem below.It is not slicer related as it is happening in every X movement regardless if printing or just moving.

@aceranic post your config

@aceranic I had to change direction as I was getting Phase warnings....
Also I have 2 motors on Y axis, connected to 2 Z axis drivers. -
@aceranic it could be a result of the fairly low jerk (M556) settings you have.
Your acceleration settings are also very low (M201) -
@jay_s_uk Ok, I didnt have such issue before with same settings. They are set higher is slicer.
-
Increased current and accwl, jerk, still the same.
-
Incresed all values but still no luck
-
@aceranic i guess its mechanical issue
-
@jay_s_uk Not sure still. After board restart it was moving fine few times full X travel. Then I started the print and same issue again.
I tried one older print large size, same. -
Are you using mesh compensation? Can you try disabling it if you are?
-
@Phaedrux Hi. Will try. Only thing I didnt try yet.
-
Yep. It seems that 25mm grid was too much to chew. Thanks!!!!
By the way Phaedrux, I ordered BTT extension for 3 drivers for my MMU. Will need help with that

If it's this board https://github.com/bigtreetech/BTT-Expansion-module/blob/master/BTT EXP-MOT/BTT EXP-MOT V1.0User Guide.pdf then I think you can only use two of the drivers with Duet 2 WiFi, as it has to be connected in STEP/DIR mode, not UART or SPI mode. Is that correct @jay_s_uk ?

-
@droftarts yep, thats correct. Step/Dir only with no UART or SPI control
-
@droftarts yep, that is the one.
The plan is to use 2 drivers for MMU.
This should be no problem I believe.
Is there a guide enywhere for the configuration of this board? -
