Hot end Part issues

[jenjaw 0]

Hi,

I have been having issues with the hot end parts of the Ultimaker with parts shearing off when dismantling the hot end to clean out a blockage. Initially the problem was the PEEK insulator and the brass tube, of which we now have replacement parts, however the nozzle has now sheared off inside the aluminium block.

 

This means we now require a new nozzle and aluminium block as removing the sheared parts of the nozzle from the block would damage the screw thread. However last time we ordered from Ultimaker it took a while and I am on quite a tight time constraint, does anyone know of places in the UK where I could get the replacement parts from?

 

Thanks!!

 

Jenny

No idea sorry. It may be already too late to mention this but when unscrewing anything in the hot end you must heat it up to at least 100C (boiling) or preferably 180C before doing this and also be very gentle. Some people suggest using only fingers (with gloves of course) and avoiding metal tools which might tempt you to use too much torque.
