i have a davinci 1.0 that ive used a ton and have done a ton of work to but this last issue has got me. the extruder temp will not read anything but 10 deg and the fan only comes on for a couple secs when turning on the printer. the extruder heats up fine but the temp wont change from 10. ive gotten the thermistor from filastruder and tried it but no change. anyone got any ideas???
If both thermistors only show ten degrees, then there is break in your wire between the head and the main board. i would try to ohm them out with a DMM. If both wires show continuity from the head to the PCB then there is an issue with the main board. I have not looked at the thermal circuits to see if they have discrete AD converters or if they are part of the CPU. If they are discrete then the one for the head is bad. If the connections for the head and the bed are the same on the board you could just try to swap them and see if the readings stay the same or the problem follows the connection. Just lower your temps to avoid over heating. Also if it is not reporting the correct temp, it may not be setting the correct temp and your head could be getting way too hot. As with the current issue the machine would think the head is always 10 degrees.

This morning while tinkering. I unplugged the plug on the right side of the extruder to clean the tip. When I did that the fan went off completely and the lcd screen display, showed 10c. Definitely ohm it out to see if you're getting connection there. Start with the easy stuff!
thanks guys for the advice, i really appreciate everything i've learned from this forum. i'm thinking it may be a problem with the board in the extruder so i broke down lol and ordered a new extruder assembly from xyz. ill let you all know if it works when i get it in next weekend. thanks again
hi carl, you were correct. i checked the wire harness from the main board to the extruder board and the black wire has a break in it somewhere so i replaced the black wire with a slightly larger gauge wire but i still have a new extruder assembly coming. oh well. spare parts. im sure ill need them as ive done a ton of work to this printer already but have learned a lot and redesigned it a little to work better. thanks again guys

Glad I could help, we are all learning here with this new animal. I am about to make the jump in to the E3D change over I think.
ya ive learned a ton from this printer. im using it to make parts for a potentially $570 million invention until i can make enough money to get the molds for injection molding. you can see it at dudad.net if youd like but ive been thinking about and looking in to e3d extruder myself
