I have a Mendel with Ardiuno 2560 and Ramps 1.4 and mechanical endstops. It's the very early Mendel, I bought the parts late 2010 I think but illness stopped me building back then so now I thought I'd use the old parts to build rather than buying new stuff.
I'm using Marlin, the latest version with auto bed levelling although I've not got that activated as yet. When I home the axes after bootup X and Y home fine but the Z motors don't move, there are no circumstances where I can get them to move either with manual stepping before or after homing.
I've swapped the stepper drivers and that leaves the problem in the same position thus proving the boards are good, I've swapped the motor plugs on the RAMPS between X and Z, this makes the Z motors move fine when I step the X axis in Pronterface but X does not move. This last test has told me that the problem must be in the configuration as the electronics are working ok.
I've tried downloading a fresh copy of Marlin and just setting the minimum settings,ie board 33 and thermo's, nothing else but everything is just the same.
I've attached my Marlin Configuration.h and Configuration_adv.h files to this post, though I haven't altered the _adv.h file. I'd be really grateful if some nice coder out there would take a look at my configs and comment, maybe make the alterations too for me.
Thanks guys
Keith
