I bought a broken ctc 2nd gen printer off craigslist for $50 and the owner had no idea what was wrong other than he had taken the hotpoint off and had cut the wires after some testing i have found that the only thing wrong is one of the wires had broken on both of them probably because he had thaken it off several times trying to figure out how it worked). I ordered a new extruder set off of ebay but have no idea which wires go where since he did not give me the old set. Can someone tell me which wires go where on the board?
