Duet 2 Maestro Microstepping settings

jaymcd0626

Hi - I am setting up my Maestro and it shows a M350 line like this inthe config;

M350 E8:8:8:8 ;micro-stepping

Not sure if I should assume that is 1/8 micro stepping or ? Not how most people show the settings.

I am trying to set my steps for a build using lead screws for Z with 2mm lead / 2mm pitch. My stepper motor is a 1.8 degree / 200 steps per rev.

I would like to set my microstepping to 1/32. Based on teh above what would that look like.

Then I assume my Z steps would be 3200

The parameter is explained in detail there.
Modes (nn)

1 = full step
2 = half step
4 = quarter step
8 = 1/8 step
16 = 1/16 step
32 = 1/32 step
64 = 1/64 step
128 = 1/128 step
256 = 1/256 step

There is a calculator for the steps per mm here

if you calculate your steps/mm at 1/16 and use that in your M92 line and make sure it is before any M350 line in your config files then any change to the Microstep rates in the M350 will automatically re-calculate the steps/mm for you.
