I have this issue with my 3D prints on my Ender 3 printer bed. The first 5-8 layers are wider than the rest (exaggerated illustration shown in the 3D rendering below), I think this is because the 3D nozzle is so close to the bed during the first few layers of the print, thus creating a rim/bulge out at the bottom. However, I can't lower the bed any further, else the model will not stick to the bed like it is supposed to.
How do I fix this issue and still allow the nozzle to stay close enough to the bed to make the model stick properly?
- I am using a glass bed
- printing with PLA,
- that I print at around 185-200 °C
- and for the bed, I heat it at about 50C °C.
- I have tried lowering the bed. Outcome: the print doesn't stick to the bed as it should and just falls off.
- Lowering the heat of the bed. Outcome: The same thing.
- Increasing the initial layer height. Outcome: The same plus the additional layers on top all go out of wack.
