Changing the nozzle with the Olsson block

Recommended Posts

Posted · Changing the nozzle with the Olsson block

Hi,

I just started the UM2 today with the Olsson block that I mounted with the 0,8 nozzle...

My first printing...Amazing of course !

I am not too sure to have really grasp the right conditions to change the nozzle ? I understood the nozzle should be hot, I imagine the material has to be removed ?

I didn't manage to find any clear instruction...probably because I didn't search correctly ;-)))

Thanks a lot,

D

I like to do a cold pull to clean the nozzle before changing with a different one. You need to heat it indeed when you tighten the new nozzle. I heat it a bit hotter than my normal print temp.

You need to change it while it's hot.

I normally go to the move material screen. This heats the nozzle and you can retract it a little if you prefer.

Change the nozzle when up to temp then insert new one. Then you can prime it to make sure it's working good before you try to print.

I usually change the nozzle at 90C. That way I get a free atomic pull with the nozzle change. :D

In addition, too cold and it will be too stuck, too hot and you risk oozy material getting into the threads.
