I don't know that board so I can't help you but even so I'm 90% sure that jennyPrinter board will only control microstepping with jumpers. Probably near those 5 stepper drivers. Marlin does support M350 but not for all stepper drivers. Definitely not for the stepper drivers that come with UMO, UM2, UM3. I didn't google 8825 though. But if it didn't do anything then it's not supported (but you might need capital letters so try that also M350, not m350).
It's great that you have pronterface going! Instead/before homing you can move axes. So move one axis at a time.
for example center all axes and then:
G92 X0 (tell the printer X axis at now at position 0)
G0 X10 (tell printer to move X axis to the right by 10mm.
Then measure to see how far it moved. You can't update microstepping through marlin (I don't think - certainly not the marlin that comes with um2) but you should be able to set steps/mm through gcode M92. (not to be confused with G92 above).
For example:
M92 X80.1 sets the X axis to be 80.1 steps per mm.

Hi mate,
did you solve your problem? I have the same and would really appreciate your help. If you have some hints, please let me know.
Thanks, Oliver

Guys I have the same card, with the same configuration. I find myself with the same problem written above. How did you solve it? Thank you very much and happy 2019

Hi thanks for the reply
I tried adjusting the micro stepping via pronterface using gcode m350 command is that right? m350 x16 y16
nothing changed.
i still get the head moving to 50mm on xy axis when i hit the red target button in pronterface.
