Ultimaker S5 Build plate Auto Leveling issue

[SparkytheProto 0]

My S5 won't print anything because the build plate never moves high enough to the nozzles, even after manual leveling. Help?

I cannot understand why it is working so bad. I get constantly an error that a difference between the print cores exceed expected value even if I print with one core. (why?) 

 

I have disabled the automated leveling with Ultituner.

Hi Viktor, I was wondering if disabling the auto leveling feature on your S5 is working or has it caused other issues?

 

My S5 is having the same issue.

Thanks 

Dan

I have disabled the automated leveling with Ultituner.

The printer always uses both nozzles for the bed level measurements. 

The first probe is done with  the right nozzle, and then the printer probes with the left nozzle. The printer then checks if there is ~1.5mm height difference between them. 
If you always get the “exceed expected value” error, please look closely to what happens and compare it to what I just described you. Especially watch closely if nozzle switching works correctly.

Create a support ticket on the Ultimaker website.

I have the exact same issue since a few weeks, thought I fixed it by replacing the spring and the lifter ring, but the issue is back again.

Done that, but problem remains. We've ordered a new print head, since we cannot afford to lose time trying new things to solve it.

 

Cleaning print cores did not work

Switching print cores did not work

Replacing lifting ring and spring did not work (the spring went through the lifting ring a few times recently)

Cleaning build plate and manual leveling did not work

 

Point of attention is that we did have a clogged nozzle recently which caused a material flood. It was a small print, so it was possible to remove the bulked material after heating the core. No optical damage was present to the print head after and the printer has completed quite some prints after.

To me it is not clear why it measuring with both nozzles even if the print would be done with one only.

After disabling of autoleveling and manual calibration everything is working fine.
