This was exactly what happened to me. Since mendel-parts seem to not respond to any message nor send the things I have ordered to repair the machine I am going to try to modify the Orca with a universal mini extruder instead.

Can you give us the URL where you are getting it from?

BTW, check the website: he's still alive!

Yes, I just read his blog. I have an order with him I would like to cancel, but on the other hand, I think that I will give him a few more days to ship. If I can get the spare parts I would have at least to extruders which probably would be handy the next time I break something The next time plastic is stuck in the brass I think it may be worth trying to leaving it in acetone over night.

I got it from http://www.ebay.co.uk/itm/RepRap-Univer ... 500wt_1170
I placed the order 24th and it was shipped 26th (saturday). I expect that I will have it today or tomorrow. This device is quite well-documented on reprap wiki page: http://reprap.org/wiki/RepRap_Universal_Mini_Extruder
and with a bit of luck it is possible to modify the carriage such that you still can use the V9 hotend if you at a later time would redecide.

Just wanted to let you know that I during the christmas holidays managed to install the universal extruder. To install the extruder you just need to make to extra holes in slide for the extruder. Everything works and I am now printing

Best,
Troels

Thanks for letting us know Troels.
