Hi folks,
Title pretty much says it all. I understand the convention of A+ A- B+ B-, which maps wires to wire colors on datasheets, and I've confirmed that A and B are in fact A and B with a simple continuity test. What I haven't been able to confirm after a couples hours searching is whether AB is A- A+, or the reverse.
I understand that I can simply hook it all up and watch the motors to see if the polarity is correct. But couldn't it be simpler? It just seems like the convention ABCD could match up to A+ A- B+ B- more transparently. I've found that preparing molex connectors is the most unpleasant part of my Prusa build so far. I have the color codes matched to A- A+ B+ B- for my motors, and ABCD specified on the (in this case) Printrboard docs. Do I really have to figure it out by trial and error, pulling wires back out of the Molex pin housings and swapping them around until they work?
Thanks for any insights!
