I tried posting this on the Repreppers part of this forum but haven't had much luck there...
I have just built my own Morgan but have run into some problems with my config. I can get the Z axis to operate and Home and when the extruder is at temperature I can move the extruder stepper.
The only way I can get the X and Y axis to move in Marlin is when I hit the home all axis button in Pronterface or if I run G28 (they only move a short distance, once either one of the axis hit an endstop, after multiple hits of the g28 command, they stop moving totally even when you hit g28 again).
I checked all my end stops and they are working when I run m119 they all say triggered or open when triggered or not
My x and y run on drv8825 which only has a jumper in MS3 for 1/16th and my z and e are running on a4988 which has jumpers in all 3 for 1/16th
I don’t believe there is a problem with the hardware as all motors move when I run the RAMPS1.4 TestCode.pde.
