oozing 120mm, normal?
when heating my bed and nozzle up from around 23-30 degree room temp to PLA (Silver prusa , came with printer filament) 215/210 degrees(layer one/after) for the nozzle and 60 for bed, I get about 120mm oozing straight down from the nozzle, measured with calipers. I am using the default profile provided in Prusa slicer 2.0. Every thing is Default, is this normal?
do you guys change your setting around even though you have filament from Prusa and are using the default profile settings for the filament?
Best Answer by bobstro:
A bit of ooze is common if you heat the nozzle up then have it wait around for the bed to heat up. There's a bit of pressure built up that can be released as the filament melts in the nozzle. A common and effective work-around is to heat the nozzle in 2 stages. First, heat it to a "no ooze" temp (I use 160C) so it's soft enough to not damage the homing and bed during mesh bed leveling, but not hot enough to ooze, then wait for the bed to fully heat and any other startup steps, and finally heat to printing temps only once everything is ready to go. This is done by inserting custom gcode into the printer settings in PrusaSlicer or your slicer of choice. I've got my startup gcode documented here if you'd like to see an example.
