Printing issue after upgrade to Cura 3.6

[prof2034 0]

I got printing issue after upgraded to Cura 3.6. At last, I found that the problem is related to the initial layer. After upgrade, it added a setting to set the height of the first layer, so it raised the print head to 0.1mm, but it doesn't allow to set the first layer height as 0.0mm. This caused the initial layer not attaching well to the print bed. Any way to fix it or any work around?

The initial layer height is meant to compensate for a non-flat buildplate. It is generally a good idea to keep it a bit higher than the rest of your layers. Lowering the initial layer height willmean that less material is extruded for the first layer, so you DON’T get better layer adhesion that way.

 

To do what you wanted to achieve (squish the print into the buildplate), install the Z Offset plugin. That will allow you to move the whole print down into the buildplate a little, up to the height of the initial layer.
