Beginner at 3d printing. PLA oozing over heater block and down the nozzle

[MrTeacher 0]

Hi,

I am new to 3d printing and only managed a handful of small prints so far on my UM2+.

On the last print the PLA has oozed out over the heater block and over the nozzle which caught on the print and separated it from the bed.

Although I have tightened up the nozzle I think I should probably tighten something on the top side but can't see how. Can anyone help? Please??

It sounds like you need to take the fan shroud off and clean up all the melted plastic. Just heat up the nozzle to soften the plastic and pull it of. PLA starts to soften at 55deg so slowly raise it till you can start to remove it.

While the nozzle it hot turn the stainless steel round bit the has all the holes in it

Put an Allen key in the hole and turn it from right to left and till it feels firm. Do not over tighten though or you will shorten the lifespan of the coupler.
