After swapping my motors to the correct ones and getting some functionality to the Lowrider 3 I am now faced with a new challenge.
I can get one of my Zs to move when I ask it to move via the screen. I swap positions of the wires for Z1 and Z2 and then the other side will work. So the gantry is only lifting at one side at a time (rules out any issues with the motors). Swapped drivers around and same issue (not a driver issue then?)
Weird thing is when I home the X; Z1 raises a small amount maybe 10mm but Z2 will keep raising and ignore the endstop. When I move the X via the screen Z2 also moves…so it looks like X is also controlling Z2 and no manual signal to z2 is getting through. I have 3 LEDS on on the middle of the board and a single LED on at Z1 at the jumper
I’ll probe them tomorrow to make sure but I’m pretty certain they are in the right place. When I run M119 they are all open so that doesn’t explain why Z2 doesn’t move alongside Z1 or why Z2 moves with X
What control board are you running? And did you buy it from V1? If so have you reflashed it? That sounds to me like you are running Primo firmware/config file instead of LR.
It’s an SKR Pro 1.2 - Got it from Aliexpress and flashed it with what I thought was the right firmware. I’ll need to check tonight.
Is there a direct link to the firmware package just to make sure I get the right one?
That seems to be a common issue with the skr. The easiest way to fix it is to break that led off of the board. The other way is to add a pull up resistor. There are several threads around talking about it. I will try to find one and link it.
