New XZmotors problem

[aceranic]

Increased current and accwl, jerk, still the same.

[aceranic]

Incresed all values but still no luck

[jay_s_uk]

@aceranic i guess its mechanical issue

[aceranic]

@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?

[aceranic]

@Phaedrux Hi. Will try. Only thing I didnt try yet.

[aceranic]

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 ?

[jay_s_uk]

@droftarts yep, thats correct. Step/Dir only with no UART or SPI control

[aceranic]

@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?
