OK this might need some explaining.
Setup
Home built frame
Nema 17 motors,
Threaded rod X, Y & Z
Arduino Mega
Ramps 1.4 (Ebay cheapy)
A4988 drivers ( 3 off X,Y & Z)
Firmware - Marlin (with changes for setup, Configuration.h attached [attachment 52040 Configuration.h])
PC side - PronterFace
Home built 3D Printer/CNC machine which was nearly working
Z was a bit jerky, X & Y were fine.
NOW, after some adjustments
Z perfect, X & Y dead.
I think I fried the X & Y drivers by adjusting them too much and now they won't work but Z does.
I was hoping to finish setting up the board with the remaining driver while some more were in the post
BUT
If I try each motor on the Z driver/port on the Ramps board they work fine.
If I move the working driver to the Y position on the board and try the motors they just about move and are jerky and wont move correctly, same with the X postion.
Any ideas why when the driver board is in the Z position all motors work, but in X or Y position none of them work, could I have a setting wrong in configuration.h, or completely blown my boards ?
