So I have been working on setting up a third extruder on my spiderbot. I managed to fry part of one of my megatronics boards when I turned up the stepper current too high. I found part of my problem, the step and dir pin numbers are flipped from what is specified on the megatroics schematic (D23, D24). I replaced the megatronics board and stepper driver with brand new ones but I still cannot get the 3rd extruder to turn from the LCD or computer GUI.
Everything else works so I am wondering if there is a bug somewhere in the firmware? The motor is stiff so I guess it is getting an enable signal, but it won't rotate. The motor and wiring is fine (I tried it in one of the other extruder driver connections).
I attached my config and modified pins file, this is from v0.91r7 (most recent). I had to make one other minor mod to get 4 rows to show up on my smartLCD (attached ui.h file).
Any suggestions?
