Because if you don't it buries the nozzle into the build plate.
Tiertime support is terrible. Great printer now bad software.

Yes I have been down that route already but still annoying that Tiertime have introduced a problem they don't seem to be aware of.
The auto level is as it says and should not be expected every print to set this manually.
Annoying to say the least when good printers are ruined by sub standard software.

Believe me it is not a feature and as they do not supply a decent calibration tool it makes the printing very inconsistent in the way the material is laid down. I have been trying for weeks now to get an answer as to what the exact thickness of the calibration tool should be. I was eventually told t...

The new version of UP Studio has a bug that is forcing a manual nozzle height check with the calibration card every time an auto level is performed.

Does anyone know of a more comprehensive manual or guide.
