Everytime I have to switch the hotend, I have to heat the nozzle first up to 100 Celcius degree to melt it unless the hotend is stucked in.
Is this supposed to be normal?
Because I have to grab gloves everytime I switch the hotend.
I was guessing you can switch the hotend even when the nozzle is cold.
There’s an unload button in the physical machines UI. I’m going to assume filament is loaded and you are heating it to 100c to pull it away rather then having the machine cut and retract filament.
ahhh. Thanks so much.
So I was supposed to execute “Unload Filament” first everytime before switching the hotend?
Yea, if filament is loaded there is a piece of plastic more or less welded into the nozzle. The tool heads have filament cutters (lever on the side) to guillotine slice it so you can remove the nozzle.
Thanks for the advice!
Using cutter or Using “Unload filament” which is supposed to be the official way to do before switching the hotend?
That is correct. Using the unload through UI is the reccomended way.
For me, I use the “Unload filament” button only if I’m switching filaments on the external spool. If I want to just switch the hotend but I’m using the same filament, I just press the little lever on the toolhead (No matter what bambulab 3D printer you use, there should be that lever on the toolhead) then I take off the sock, unlatch it, and swap the hotend.
