Can't get past initial setup. Bed won't calibrate

I just got this built this weekend and I was trying to do my first 3D print. I can’t even get past the calibration screen. I try to “Calibrate the Bed”, it pretty much puts the module in the top left and then bottom right, never touches the bed, barely moves on the Z axis. then goes to the around the middle of the bed and says to “Please level the last point”. The extruder is good 2.5" from the bed at this point. No matter what I do, I can’t get the “Save” button to turn blue so I can save it. I’ve pressed the damn .5mm button a million times try to get it to a place I can save it. I can’t do anything to get past this screen

I connected to Luban via wifi, and although I can move the Z axis with the controller, it will NOT move in Luban. it just sits there. X & Y moves as expected in Luban.

Any help is appreciated! Thanks for reading.

It’s worth ruling out swapped cables. The toolhead should start in the back left corner of the bed and then move to the front, then right, and continue in a counter-clockwise spiral when looking down from above.

Yeah I verified the cables were correct three times. Everything looks good. Thanks for the reply though.

When the power is off, can you push it all the way down? (power must be off or the stepper motors will try to keep it in place)
It will take some force, but it’s most definitely not like you should put your full weight on it.

If you pushed it down passed where it gets by itself, does it still move when you turn it on?

Actually what I want to verify is if it’s mounted parallel on the z-axis.

You can also unscrew the x-axis. Power it up and and see if they move down.

Really sounds like a swapped cable or build problem.

Also could be a faulty limit switch.

Or a dead linear module.

You’d better to check the booting log of the machine.
Please connect the machine with your PC via the provided USB cable.

  • Launch Snapmaker Luban
  • Select the correct serial port
  • Input the command in the console

You can see the length, module type in the booting log.
Three types:
- Snapmaker A150: 165
- Snapmaker A250: 256
- Snapmaker A350: 356

Three codes:
- 0 for X axis
- 1 for Y axes
- 2 for Z axes

If the controller does not recognise all linear modules, you need to find which one is missing.

I woulde suggest to mount the cnc module and try to jog all axis with the touchscreen to see if your machine properly works.

My guess is that your proximity sensor could be broken, so that its actuated all the time (is the red light on all the time?)

Hi all. I wanted to thank everyone for taking time to help me solve this issue. Snapmaker support contacted me and asked me to swap my Y and Z axes cables (after removing the X axis and bed). This showed that the Z-axes would work when plugged into the Y port, but Y would not move when plugged in the Z port. I then tried each Z-axis individually, by passing the splitter. That all worked as well. I ended up plugging Z axes back into the splitter and trying again, and it worked!

So, I’m really not sure what the issue was. I had everything plugged in the first time. My only thought is that one of the Z cables was just not snug enough or had some issue that corrected itself after unplugging and plugging it back in.

Anyway, I put it all back together and now everything is running smoothly. :slight_smile: Thanks again!
