@deckingman Could you please share your config.g?
Thanks!

@fcwilt yah, weird behaviour...
Let's try to bring @dc42 to this topic to help us understanding it

Hello guys, as I already said in my case the problem is that the 3HC card is not accepting the current settings of the motors, I believe that my config.g has the M906 configured correctly.

I have to check with M112 the status of the voltages as @Phaedrux is suggesting. All of my power wiring is 14 gauge.
Unfortunately only next Monday I will be able to do more tests but I will be following this topic carefully because I realized that I am not alone with this problem.
Thank you all for the support!

@fcwilt Thanks for you feedback!
Could you try what @deckingman is suggesting, sending just M906 without parameters to check the motors currents?
Thanks!

@deckingman Could you please share your config.g?
Thanks!

@deckingman because it's clear that there's no torque.
I'm using the same type of nema23 in all axis, the 4 Z motors are connected to the 6HC and I can set the current and it's working,
X and Y not, if I replace it with a nema17 just for debugging it works ,but without a strong torque.

I'm not using 1XD I'm using 3HC with 3 integrated drivers...

@fcwilt Thanks for your reply!
How to set the current in the 3HC itself not using M906?

Hey!
This is my first topic and I hope to get my problem fixed

I don't know why but my Duet3 3HC is not accepting the stepper motors currents settings... Maybe it's a mistake in the config.g

Do not be alarmed by the size of the printer, it will be really giant ... as soon as I have permission I will publish some photos

Thanks in advance!

Here is the config.g
