Just started trying to wrap my head about how to wire this all up. I have a RAMBO board, LCD and the Z 84oz steppers wired up. I’m trying to raise and lower the gantry but its only moving down. When I flip the whole assembly upside down the motors will move in both directions but doesn’t seem to want to lift the weight of the gantry even without the weight of the router. I can rotate the lead screws with two fingers pretty easily when power is both off and on. I’ve also bored and cleaned up the hole for the lead screw nut in case warped parts is causing any binding.
Is there any settings or firmware things I need to worry about? I noticed the LCD looks like its set up for 3d printing. I’m all new to this kind of stuff, I’ve got mechanical aptitude, but wires scare me.
These are the steppers I’ve purchased:
Any way of testing them? If one goes bad will it affect the other?
