Nozzle offset probe failed

[Qia 0]

Hallo everyone，

 

My printer is S5:

It shows at the beginning:

Difference between dected height of both print cores exceeds realistic values.   (nozzle and glass plate are clean)

Nozzle offset probe failed.?

 

And I found that the two nolzzes are not on the same level and the distance is too large.

 

What should I do ？

 

Thank you very much.

I don’t have an S5, but it looks like it uses the same nozzle lift switch as the UM3.

 

The reason your nozzles are at different heights is so only the nozzle printing is at the part layer level at a time and the other is reading above the part. The left nozzle, #1, is fixed in height. The right nozzle moves up and down by means of the “lift switch” on the right side of the print head. You can move this manually to see how it works.

 

normally the printer moves the switch by inserting it into a white bracket on the right side at the top of the machine. If it’s missing the gap it won’t switch.

 

it sounds like you need to do the lift switch calibration. I had the opposite problem with the switch rubbing noisily leading to some tips in this thread
