Hi I'm brand new to the Reprap world and have build a Prusa i3 with some students at the school where I work but have got bit of an issue and am trying to stay one step ahead of the students. The issue is the pins on the motor are labelled (A+,B+,A-,B-) as they leave the motor and the pins on the board are labelled (2B,2A,1A,1B in this order) The supplied cable follows the pattern on the motor which doesn't seem to line up with the label on the board.
I apologise for the lack of technical language but its really early days for the electronics side of things for me. If anyone can point out what is going on here and how I might procede without burning something out or frying a student I would really appreciate it. Eg what does the 1A etc mean in relation to + or - and is there a way to check all this.
Thanks for reading this.
