But I suppose the 5.3:1 gear ratio plus the 8825's will get close.
Seriously though I still run X,Y&Z at 1/16th.  I think I'm going to change that tomorrow smile
Gotta love the options of the Rumba.

Yup, exactly.

To confirm, use a ruler to estimate how far the nozzle moves when you use the manual controls in RH - if you request 10mm, and the nozzle actually moves about 5mm, then it is likely the 8825's are doing 32x microstepping instead of 16x, and you need to either adjust the jumpers or double the step rate as you propose.

Anybody know what to change in the firmware?

It's a Pololu md09b. Is there a equivalent  driver that I can use?I have looked but I haven't found the exact replacement.
