Got the Elefu RA v3 in - I’m impressed by the discreet dual z-motor attachment points, and the quoted amp figures in the documentation from the standard ATX power plugs. It heats up my extruder and bed really quick - but I’m having issues with the stepper drivers and limit switches. The motors move strangely or not at all (you can hear them engage), and despite trying a few different hookups to the limit switch connectors, triggering them doesn’t stop a y-home (only axis moving well so far.) I’ve turned up the poteniometer on the drivers from 0 until I got movement, but still am struggling. My adapted configuration.h is here: http://pastebin.com/8Bz4f75P . Maybe @nop_head or anyone else can spot a problem / give me some advice… Thanks!

Is that Sailfish, or Marlin based firmware?

Marlin

I’ve got the same one from the Kickstarter. Going to be hooking up the motors and sensors this weekend on a MendelMax2.0
