all temp readings show 'def' and printer goes offline

Post by frankjoke »

Dear all!

I printed an ABS part and after 3h (about half of print) theprinter just stopped.

After switching it on/off it shows after very short period <1s the temperature reading as 'def' and after connecting the stepper motors work but as soon as I set any temperature printer goes offline again.

I assume problem is in controller because steppers work and therefore powersupply should work as well.
Just heating kills the system. What do I need to do with Felix?

Not sure if what you saying is the case, but I get "def" reading once there is any disconnection of any of my two thermistors. Maybe check connections. Or maybe faulty thermistor?

Regards,
Jan

This was a good tip!
I checked the thermristor and found that the one of extruder1 is disconncted if head is on right (x=0) side, so it seems to be a break of cable. If I move head to left(x=200) then I get no error.

Will have hard time 2morrow to re-cable the thermristor :(

I also re-cabled the thermistors and as somebody made a point here a put them completely separate from high amp wires.
