    Hi guys,

    I just broke my heat-break while disassembling the hotend (blockage problems). Now it seems the 1.75mm version is out of stock. Is there any chance to get hands on one of those without paying for a whole new hotend set?

    I am kind of desperate here.

    cheers

    These are EoL'ed, not produced anymore.

    I solved my problem, so in case anyone is interested, here's the plan, valid for 1.75mm filament.

    In case you have access to a well equipped workshop (mine was from a university). It it possible to cut an M7 threading into the end of the v5 heat sink, the hole has to be 14.8mm deep, the threading does not have to go all the way, around 12mm is enough. Then drill a 4.2mm wide hole through the whole heat sink. That's it - your v5 heat sink is now compatible to a v6 heat break and heating block. Works like a charm, you may run a PID autotune and slightly adjust the control parameters.

    This is not such a great idea, the v6 break requires PTFE and as it is you have no means of retaining the PTFE in the break (no embedded bowden coupling).

    All this to save what, $15?

    My intend was not to offend anyone, but it seems I did.

    Due to the 4.2mm hole through the heat sink, the PTFE tube fits into the heat break, as intended. My original problem was that the v6 is a lot shorter than the v5 and I am not smart enough to adjust my extruder design+everything surrounding it. For my case, the PFTE can not slip out because it is held in place by a plastic part that was already there extending into the v5 heat sink.
    All I tried was offering a possible solution with the same or related problems. It was not about saving $15.
    It is nice that you pointed out the pitfalls of this method, though.
    Still, you don't have to unterstand what I like to waste my time on.
