Throat(Tube) broken inside the heatsink (x-axis holder)

Printok

Hello Community,

I have a big problem:

I have managed to brake the throat in the heatblock (the one with the teflon tube inside). Sadly it broke apart directly at the connection into the big heat sink (which is mounted on the x-axis). I wasn´t able to extract the part of the tube which is stucked into the heat sink. I have nothing left of it outside to hold it tight to unscrew it.

I fear i will not manage to unscrew it, so the complete heatsink-block including the x-axit mount is useless.

Do you have any idea what i can try?

Part of me already accepted the loss and i searched for new extruder possibilities. But as i am totaly new to 3d printing (that´s why i bought this complete printer;)) i have no idea how i can build these hotends (i found e3d v6 for example) to my x-axis, as the heatsink included the whole transportation system in this printer.

So how is it possible to put a new extruder on there or can i get the original heatsink/carriage as spare part?

I hope my problem became clear. Maybe someone can help?

With kind regards,
André

Hi André,
in hardware stores or online you can get screw extractor tools, which look like a thread tapping tool, but has a left turned steep spiral. 
see https://en.wikipedia.org/wiki/Screw_extractor
You can get sets of such screw extractors in different sizes for a few € / $. For the case that filament has "glued" the remaining throat part into the heatsink I thing its supporting if you heat the dismantled heatsink (without all other parts like linear bearings, fans, etc) to ease removal.

Replacement throats M6x30 with inside teflon tube are available on e.g. Amazon

Hope it helps

You may be able to remove the broken throat by undoing the grub screws on the side of the x-carriage. 

If you just need a new throat that is not expensive: https://sampin.ch/bg-A5-throat

However, if you need a new x-carriage block too, that can be purchased from JGAurora directly:

Thanks, both of you. I have tried to extract the threat without success. But i have ordered the replacement you mentioned from AliExpress, hadn´t found hat on my own.
