SEEKING HELP TO INSTALL DRV8825 STEPPER DRIVERS

[mechaneil 20]

Hello. I'm in the process of replacing the original stepper drivers on my UMO. I got the DRV8825 from amazon https://www.amazon.com/gp/product/B01N3YHJ9J/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

and would like to get some pointers and steps on how to install them. Here's some of my questions.

1. What is the orientation on the board of the stepper driver for the X, Y, Z and Extruder motors?

2. Are there any hardware adjustments (ie, pins, wire plugs orientations) that I need to follow?

3. What are the changes needed on the firmware?

4. What are the stepper voltage values that I need to set each drivers. In what direction does the "pots" rotate to increase/decrease the values?

A clear cut step by step guide would be greatly appreciated. Thank you very much.

Huuu... If you have a chance, change them to e.g. SilentStepSticks aka SSS aka TMC2100 or TMC2130.

There are a great tutorials for the mod available here (did it on my UMO and i´t damn silent now)

But maybe this tuts can assist in placing your drivers too...

Thanks for this great guide on the SSS driver. Might upgrade to it down the line, but for now just want to install the DRV8825 drivers. Really need a guide on how to install on the UMO board.
