Re: hotend no longer heats up

I originally purchased a Taz 4 and have since upgraded to the Hexagon hot end (to include Q2015 firmware). After my Hexagon extruder became clogged, I really wanted to print something so I re-installed the original Budaschnozzle 2.0c.

After heating up to the almost desired temp of 230C, the extruder head stopped heating and won't heat anymore. Did I mess something up by using a Budaschnozzle 2.0c with the Q2015 firmware? If I place the clogged Hexagon hot end on, it heats just fine.

Note: I did not go above 230C with the Budaschnozzle (even though the new firmware lets you).

The heater resistor in the Buda is probably smoked. The firmware for the Hex hotend allows a lot more current to the heater cartridge in the Hex. The Buda's resistor can't take that and tends to burn out. Also the Hex and Buda use different thermistors so the temp reading is off if using the wrong firmware.

Thanks!

Kcchen, I'm confused as to what hot end kv1 was using when he went to the heater cartridge. Can you use the heater cartridge on the buda V2 hot end

I've only had experience with the metal hotends. The hexagon and E3D both use a heater cartidge with is inserted into the heater block.

From what wantmys2000 wrote, it sounds like the buda uses a heater resistor.
