Customizing Firmware to upload to UM2 Board

[Wcj97 0]

So I recently got a hold of a used control board out of a UM2 printer. I’m working on a custom printer design, and I’d really like to use the board to control it; at least for now, so that I don’t have to dish out a bunch of cash for a new printer controller (eventually I’ll be using a Duet Maestro).

 

The printer I’m building will be a CoreXY, not the typical Ultimaker geometry. Also, there will be no heated bed, and for now I plan to just drive the printer straight from a computer as I don’t have the SD reader or LCD. 
 

my question is: how can I go about changing the existing UM2 firmware to work for my project? Can I upload the standard Marlin build with the correct configuration.h for my setup, or is the pinout setup differently for the UM2 version of Marlin?

 

Thank you I’m advanced!

not a complete answer... but here's the pinout ;

In short: yes, it should be that simple.

 

Just choose the correct definition:

 

#define MOTHERBOARD 72

 

...or for newer Marlin version you can use the definition from boards.h as well:

 

#define MOTHERBOARD BOARD_ULTIMAIN_2

 

I'm not sure how (or where) the pin definitions are included nowadays..., the correct configuration seems to be in:

"pins_ULTIMAIN_2.h"
