Question about the Duet maestro,
I have a M3D Crane Quadfusion. It uses a Duet Maestro. In various groups we are working on dialing in our printers and figuring out the ins and outs, but the documentation varies. So I thought I would come here to the source for an answer that has been plaguing us for a while, with different answers appearing in different places.
In dialing in the motors with m906 you specify the current in ma. Question is what is a valid amount.

Indicates steps of 100 ma which are rounded down. (but maestro not specified)

comment here by dc42 indicates:
" Stepper motor current is adjustable in steps of 100mA on the Duet WiFi/Ethernet, and 50mA on the Duet Maestro. "
This would seemingly be the end of the question here. BUT for a few things.
- It would be great to see this somewhere in Maestro documentation.
- Someone else has been told by M3d support that 40ma is the minimum increment they should use.
- Firmware for the M3d Crane Quadfusion comes with a default of 480 on the extruders. (smaller motors than the others) Note that 480 is not divisible by 100, 50, or 40. So that could either indicate a smaller increment, or that it is just placed there for some readon to get rounded. (Why would you set it up that way?)
What say you?
