Topic: Help with Home location on RUMBA and SD3

I swapped out the SD3 stock board for a Rumba, and doing some testing right now with just the x axis.  I realized the hard way that without xmax endstop jumpered, it wouldn't move...  However ran into a different issue.  I am using the firmware from here: https://github.com/mlaws/solidoodle2-marlin.git

I am using the stock settings other than switching the board type to SD3, and motherboard to 80.  The issue I am having is that when I hit the manual home button in Repetier or Octoprint, rather than going to the right and hitting the end stop as I am used to, keeps going to the left (well trying to, until I pull power before it hits the end.)   I feel like I am missing something stupid...  I feel like in my head maybe I've screwed up what I thought was xmin and xmax somehow?   

Thanks,

-Mike

Stepper motors could be plugged in backwards, as the firmware should take care of the homing direction and coordinates.

BINGO, thank you... I was going off the wiring listed on the board or the Rumba wiki page both were wrong.  Pulled up the Y connector and noticed the red/blue were reversed. THANK YOU.

No problem.

There is a setting in configuration.h where you can invert stepper direction. The instructions you were following were probably for the opposite of what the Solidoodle Marlin has.

That makes perfect sense.  Also didn't help I had the printer turned around so testing from behind, so wasn't noticing when using manual control it was moving in the direction I should have expected.
