Heat bed not up to temp
Filament suddenly stopped adhering. Tried different filaments, pla & PETG. The lcd said the bed was at 60C, but it was just warm to the touch. Should have been HOT!
The thermister seems to work. Responds to heating with a hair dryer & shows the bed temp rising when prints start. And yes, it’s firmly attached to the heat bed. But the bed is nowhere near what the display shows
I tried tuning a print from 60 C to 88C and adhesion improved.
Any ideas would be appreciated!
thanks!
The bare heatbed is losing heat to the air, the temperature underneath a layer of extrusion will be higher. For poor adhesion the number one criterion is a truly clean print sheet. Narrow footprint adhesion can be improved with a higher bed temperature with the trade-off that elephant's foot will increase.
Cheerio,

Thanks for your reply, Diem, but I don’t think that’s the problem. It’s worked fine for a long time until this suddenly started happening.
