Just finished the wiring on my Workbee 1510. Nema 23 high torq steppers. No matter what stepper motor gets plugged into the Y2 port. It will only go 1 direction. Tested all wiring, stepper motors for breaks and made sure i was using the right coils. I am running both Y motors on Y1 right now just to use the machine. Anything to look at for Y2 only going 1 direction?
Double check coil pair identification: docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation] Double check that the Y2DIR jumper is in place docs:blackbox:jumper-slaveaxis [OpenBuilds Documentation]
Coil pairs match up. Jumper is in place for Y2 to clone Y1. I have both Y motors wired in parallel to Y1 to use the machine. Y2 port only goes in 1 direction.
I pulled jumpers and reset them. In case they were not making connection. Wired in parallel to Y1 everything runs smooth. If I put any stepper motor into Y2. Moving positive direction it will go positive. If I move negative direction. It will move positive. When this happens. It moves smooth. Just the wrong direction. Same wires plugged into another port. Everything moves the correct direction.
No bent pins on interconnect between the boards. Y2 gets its DIR signal from the jumper, and jumper gets it from Y1. Y1 works so we know there is a signal, jumper is just passing it to second driver via interconnect between the boards. So worth a check
No bent pins. Ran a test. Changed jumpers to clone X. Y2 worked in both directions for X. Same for Z. Y2 just doesnt work in both direction for Y.
That is super weird. So the driver is fine (gets signals from X) Y signals of the ATmega is fine (else Y1 would also be affected). Between the two is just the jumper. Check soldering on the pins below the jumpers?
I dont see any cracks or damage to the soldering. I can remove the Y2-DIR jumper. It does not change a thing. Maybe faulty pin?
Still not sure what it is then, but I take it you've contacted the store by now? http://support.openbuilds.com/support/home
FWIW, I just had the same issue and I realised I hadn't changed BOTH jumpers, the Y2-step AND the Y2-dir jumper (it was in X), and so Y2 only went one way - changed motors ports, issue followed motor change.. changed to X motor slave, and Y2 motor followed correctly X motor.. then revising photo realised you have to change BOTH jumpers.. didn't read enough and hadn't looked at the photo correctly.. IMHO, maybe putting the word "BOTH" in bold and below each photo may help the idiots like me ;-)
