Cleaning build plate (was How hot is too hot for FDM printing?) (midwest.social)

I recently had two print failures on my Ender 3 Neo. In both, it looked like the part came free from the heated build plate after about an hour or so of printing. Both had good starts in the first 15 minutes or so. I had a successful print finish two days ago.

It has been hot and humid here today, and my printer is in a non-AC shed not connected to the house.

I'm wondering if I should wait to kick off the next print until this evening when it should be cooler. Do I need to clean the build plate? I've not done that at all, other than make sure these isn't any filament left on the plate when it finishes.

UPDATE: It's apparent the problem isn't the heat, but the fact that I haven't cleaned the build plate since... well, ever. Adjusting the title to reflect that.

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
