the machine will heat the bed and wait until the top plate has reached at least 32°C
the ideal probe temperature is at 210°C to minimize PEI damage, but these temps are too low for filament on a dirty nozzle to be squished out of the way as the material will be solid, so instead the machine will probe at above the melting point of the material (220°C for PETG, 240°C for nylon). These temperatures are set using the idle temperature box in the filament settings tab
after probing, the machine will then preheat to the actual print temperature before printing, but due to the elevated temperature, the hotend will expand downwards resulting in too low of a first layer height, a fixed, tuned offset is applied (+0.02mm for PETG and +0.05mm for nylons). These offsets are found in the custom g-code of the Filament settings tab for each material
