I have been having a lot of problems with nozzle blocking.

In the course of removing the nozzle to clean I have broken the heater cable from the block. Is it possible to reconnect the cable or is a new hotend needed?

If new hotend is needed how do I find part number?

Thanks for your help!

You only really need a new heater.   BUT the screw holding the heater in place  is often difficult to loosen, 

the manufacturers E3D, sell a sock and block pack

Heaters

the Mk3 uses a 24 volt 40 watt heater
the Mk2 and Mk2.5 use a 12 volt heater... MAKE SURE THAT YOU GET THE RIGHT ONE    if you put the wrong heater in a Mk3, it will try and pull 160 watts, and will wither melt something you don't want melting, blow a fuse or burn out quickly...   the wrong voltage in a mk2 or 2.5 and you will not be able to achieve the temperatures you need to print! 

It's always a good idea to have a spare thermistor as well   (the wires are very fragile)  I suggest you get at least one, as there is a chance that you will damage the thermistor wires whilst trying to replace the heater

If all else fails...  you can get a complete hot end

Hi Joan,

Thanks very much for your reply.

Heater and thermistor ordered!

Didn’t realise there was a UK supplier.

Regards,

Barry.

E3D which makes the hotends is a UK company.  Bit a bit weird if they weren't available in the UK 🙂

In my book, parts from E3D are as recommended as getting them directly from Prusa.

And a heck of a lot cheaper on shipping.

Doubly nice in the states - E3D has a good selection on Amazon. Two day free shipping with Prime.
