Hi guys,
I'm having a problem where the bottom layer of my prints start off smaller than they are supposed to be, causing the bottom to be caved in. This happens consistently up to around 3mm height, then the dimensions return normal. How can I fix this?
I've tried various prints fiddling between the following range of settings, but they didn't have much effect:
Material: PLA
Print temperature: 190 - 200C
Heat bed: 50-60 degrees C
Extruder dia: 0.4mm
Print speed: 20 - 45mm/s
Layer height: 0.15 - 0.2mm
Raft/support: Yes
Cheers,
Ben
