I asked there but didn't get much more of a reponse. Thought I should update here though. The main chip (AT90USB1286) takes in the E-therm on pin 60. This is what has failed. It has caused an internal fault to ground with a resistance of .217ohm. So in order to fix this, I have to replace this chip..... I can get replacement chips for around $25, but then I have to unsolder a chip with 64 piby cjensan - Ormerod
Thanks Matt, I had found a number of topics on this forum, hence asking again. Sorry about thatby cjensan - Ormerod
I have managed to find the schematic here. With following this, I believe that I likely have a failed capacitor on the E-therm circuit as the reading is way off compared to the B-therm. I will go to my electronics store tomorrow and get a couple 10uF surface mount capacitors, and replace them, and post an update..... I hate surface mount soldering btw.... thankfully I have solder wick and suby cjensan - Ormerod
Hello all, I'm a new user to the forum, but have had my printer since the end of Dec 2013. It's a printrbot machine that a local fellow assembled setup and sold to me. However I have had numerous difficulties (including a mainboard failure). Most recently, I started to print with Taulman's 645. Excellent product btw! I did roughly 12 hours of printing with this.
