Fan shroud touching olsson block.


Recommended Posts

Posted (edited) · Fan shroud touching olsson block.

I have recently been having underextrusion issues and figured out that it was due to the shroud touching the nozzle. Can i use a drill bit and make the hole bigger? I have a um2

    Normally it is enough to loosen the four screws that hold the whole unit with fans and the whole thing. You can then adjust using the screws or possibly bend the fastening arms to center the nozzle.
    That was all I needed to do.

     

    Thanks

    I've come to think that you may have the old type of shroud?

    Then there might be pretty tight.. In this case there is no problem, - but for stainless steel and drill bit "can be scary" ..

    Grinding with Dremel might be the choice.

    I've had that issue a few times and was always able to fix it by either rotating the round nut and raising the heater block or by loosening the 4 screws and adjusting the fan shroud slightly as Torgeir suggests.
