Yeah the motor pulls in the filament, we even tried to push it in while it was loading. Then we tried a using a panel pin up the nozzle, but it wouldnt fit, I couldnt believe how small the holes are, as I dont think even a pin would fit.... We did notice the plastic wasnt even warm when we took it out,, so even tho the printer says its getting to 230c+, it might not be at all and I don't wand to touch it to find out.. Im am thinking though, if I took it somewhere to be sorted out, would they be able to get the parts any better then me?
So if the worst comes to the worst, the printer can use different sort of head, but Im guessing the carriage will need changing aswel to accept the E3D V6 head.
I have been trying other peoples settings in Slic3r for my printer but I keep getting quite rough prints if the print outs are slightly complicated, like I did 2 chess pieces and they printed out quite rough.
It looks to me that the hotend is not heating up. Don't trust software you haven't setup correctly.
The obvious answer is it heat it up the touch with a bit of filament. The hole is 0.04 in size.
As I said get the one hotend working first. Now shop can help you.
As for changing the head first you have to print out parts(which you can't do) you would have to print a carriage as well.
Then find the right bearings for it. Not easy.
If it printing then you have to dial it in. We all have to do that and it takes time.
