Could use a lil help here, in the process of building my Lowerider 2. Got everything but the ends endstops connected. Testing the motors and for some reason my Z1 will only go up. Flipped the steppers and the issue moved. Changed the driver and the issue still remained. Could use a lil guidance, sorry noob here
The machine should drop under its own weight. Something is binding. Have you lubricated the leadscrews? Or maybe they are over constrained, they can be sensitive to that. If you post a photo of the bad side, someone might notice if something is on there backwards (I’m always bad at that).
When you move down, does the bad side hold in place or does it move up?
If it moves but in the wrong direction it suggests the DIR pin may be shorted or somehow bad, or there could be a firmware issue causing that pin to get stuck.
Just realized I opps’d on my last response. The bad side always goes up. No matter what I do the bad side moves up. If I flip the connector for the bad side, it always goes down. I’m thinking its gotta be a bad board. If I swap the driver it still does the same thing. New board is on order now.
Best is probably if you unplug the drivers so you don’t accidentally short stuff.
Try moving up and down and see, if both drivers are being given the same signals. If the board is bad you might see the good axis switching between +5V and 0V, while the bad axis is stuck either on +5V or on 0V.
I’ll give that a shot as soon as I get home. I’ve gone through the firmware line by lone and it all looks correct. I’m thinking it has to be the board. Literally just came in on Friday, looks like it might be going back to Amazon.
