Z-axis not working with Duet Wifi Firmware

[coolm8 0]

Hi,

I want to use my Duet Wifi Controller Board for my modified Ultimaker original with a custom heatbed.

I have been trying to configure the Duet according to the Marlin configuration and the X and Y axis work just fine. However, the Z-axis does not move to printplate at all. The sound it makes is pretty much the same as it is when it was working with the original Ultimaker Board.

Here you can see my Motor configuration:

What am i doing wrong here?

Hi, your M566 is setting the Z jerk to 24mm/min, is that right? Seems very low to me but I am not familiar with that machine.

Well, that is because in Marlin (https://github.com/AmedeeBulle/Marlin/blob/Marlin_UMO_Unified/Marlin/Configuration.h) it is configured to be 0.4 mm/s so that is 24mm/min.
