Yeah mate clean the plate, I wipe my glass with 60% alcohol before every print. Most people recomend 90% isopropyl alcohol and sometimes dish soap and hot water for deep cleaning.
I dont think you have problem with too hot room, but you might need to lower bed temp a bit to get the same actual surface temp. What temps are you using? Printing pla?
Too hot bed can help with adhesion, but can cause lifting, so I print first layer at 60 and rest on 56 C for example. Big prints are more likely to lift mid print, its not bad to use brim and maybe even mouse ears. If you surface is not clean it might be painful tho
I'm printing PLA+ at 200C nozzle, 60C bed temp. It's been fine so far with a few failures I've filed under "User Error".
OK, now I'm curious how I change the bed temp settings after the first layer -- something in the slicer? I'm using Ultimaker Cura, and have just recently been digging into the advanced settings.
Yeah you can change the settings in cura. I believe it’s under the materials section after you injure the setting
Its called initial layer bed temperature. You can tune different settings for initial layers (temps, speed, fan speed etc). You deffo need 0 fan on first layer as well.
Alternatively you can use Change At Z script or just manually change temp on your printer lcd
