| Jun 26, 2017 at 17:08 | comment | added | Ecnerwal | This reminds me of a thing I had happening that appears to be a bug, albeit with different software. Are you looking at the first layer as it's printed? 3dprinting.stackexchange.com/a/4192/6853 I was getting no extrusion until the second layer until I figured that bug out - it made for some parts not unlike yours. | |
| Jun 26, 2017 at 9:25 | comment | added | Tom van der Zanden | Initial Layer Height is the height of the first layer. If you set it to 0.3mm, the printer moves the head up to 0.3mm for the first layer. This is normal. It is presumed that Z=0 means the nozzle is touching the bed, so it has to move up slightly to allow the plastic for the first layer somewhere to go. If you use the paper test this means that the nozzle will be slightly above the bed when Z=0. Having slightly more space between the nozzle and the bed than the first layer height is often desirable, but in this case you have a bit too much. | |

@TomvanderZanden I noticed when watching the print run on the printer that it was starting at z0.3. Looking at the g-code, just before it starts the skirt it does a G0 F3600 X76.789 Y75.642 Z0.3 Why? I have "Initial Layer Height" set to 0.3. Maybe I am misunderstanding what that means.

| Jun 26, 2017 at 6:32 | comment | added | Tom van der Zanden | How is the part popping off with "very little effort" consistent with "great bed adhesion"? You got extremely lucky that this part stayed on the bed for the entire print. A properly adhered first layer, especially PLA on glass, will be very hard to remove (and if your adherence is too good, chips of glass might end up stuck to the PLA). | |
