    I am currently working on a BBC hybrid dual. I have gotten to step 7 in commissioning. This is where I hit a road block. When heating the left extruder, the nozzle will get to around 200°c (when I requested 285) then give me an error HEATING FAILED. The printer then won't respond and the only way to get it to respond is to switch off power and reset. Same happens with the right extruder. Please help!

    This sounds like it could be a dodgy connection somewhere, either in the heater or the temperature sensor. Double check you have connected everything up the right way round, and that all the connections are secure. You may want to also check the resistance of your heater cartridge to make sure it's in spec as per http://wiki.e3d-online.com/wiki/E3D-v6_Assembly#Heater_Cartridge

    It seems to be the sensor because it heats up fine then just stops. I'll look and try and figure it out when u get home.

    Can you post a photo of the hotend please. Clearly showing the heater block, heatbreak and heatsink.

    Thanks

    One thing I can spot there is your extruder isn't quite assembled correctly which could cause this. The nozzle should be screwed into the block first with half a turn or so to go before it tightens up.

    Then you screw the threaded heatbreak in after, then heat the nozzle and tighten it. There should almost no gap between the nut on the nozzle and the block and be a gap between the fins and the heater block and I'm guessing by the position of the nozzle on yours there is no gap.

    Reread the e3d assembly steps, And check what you have done there

    Also the heat cartridge does not appear to be screwed and clamped into the heat block.

    It is clamped in. I might have moved during clamping thought. Thank you for pointing out the gap difference. I will read read the instructions.

    Dr jeep you are amazing. Making the gap be between the heatsink and the block made all the difference. It will now heat up to 285 easily!
