There is an issue printing an 'a' while printing a name 'Matt' for my box. The blob in the middle of the 'a' does not stick well to the bed. I have tried 3 times and failed. It keeps coming off. Please advise..

    The problem is that the "island" in the a is not at the same z coordinate as the bottom of the mesh. So the island actually sits a bit above the mesh and does not get printed on the first layer. The difference is about 0.2 mm

     

    You either have to fix the model, or you have to sacrifice 0.2 mm of your model by lowering it "into the buildplate" in Cura (ie: set the z of the model position to -0.2).

    Many thanks for your reply. Where would I find the 'Z' in Cura settings ? A snapshot please.

    Hiya..........many thanks. It was my model which I found the 0,2mm different. I have corrected now but another issues arises after I printed the same model but with a different name to mind. Attached are photos shows the lumps. My settings in Cura was see attached snap shots. The thickness of the lid is 2,00mm and the depth of the name is 1,00mm.

    I did not turn on the fan on my printer machine then, maybe it was the issue with 100% speed and I have reprinted again and there are a small couple of lumps again with speed at 65% and the fan on this time. Oh.........I hate seeing these lumps appearing and what caused the problem. Please advise again and many thanks for your help and input. Take your time.
