Dopeskrit, thank you, if you push me the pico table I can add it to  the fw , soon I will do some update and also integrate latest fixes from repetier

I found it on the internet i dont tested it and cant test it because i have an e3d v6 in my printer. Maybe add a installer so its easier to flash?

Hello All,

I flashed my printer back in January or February and used it for months without any problem until I decided I wanted to upgrade and install the pico. Well when I upgraded I was having issues with the filament not feeding correctly which then eventually led to this heater decoupled error that displays after the extruder fails to heat up. So far I have:

Removed that clip connector completely for the extruder and soldered wire to wire
Replaced the whole wire to the extruder
Cut the plug that connects to the back of the printer and soldered it directly to the pins
Went back to the old extruder and still erroring out

I am pretty much out of ideas any and all suggestions are greatly appreciated.

Try upload this to your printer https://drive.google.com/open?id=0BykBb … k9HMjIxTHM I modifyed the thermistortable from https://github.com/luc-github/Repetier-Firmware-0.92 BTW BIG THANKS TO LUC for the firmware I LOVE YOU (NO HOMO ). Maybe you plugged the Thermistor into the Fan spot on the board. Maybe the mainboard in the back is broken if it is you probably have to switch to an ramps board. Have you tryed directly solder the wires to the mainboard in the back? Maybe try go back to the original firmware and look for the error code (https://www.youtube.com/watch?v=sU5G0EX_Q08) ?

if yes table are not corrects, davinci board is not a ramps unlike you modified it

I did, but that wouldnt explain why it didnt work when I installed the stock extruder again

The problem when back to stock  is another problem - Davinci is very very  fragile and very sensitive to error wiring - easy to blow fuse

heat extruder with hair dryer be sure your problem is extruder sensor and not bed and check temperature is up

I would suggest to connect only sensor at first, no need to connect heater, and check wires and fuses

After if sensor is ok, then connect heater and heat extruder using printer menu and check how temperature raise before error of decoupling happen

If no heat on extruder check this thread : http://voltivo.com/forum/davinci-peersu … r-fix#7045

Did you try looking at the R271 resistor near the 12v hotend connector?

I have not is this resistor on the mainboard itself?

The heater decoupled error occurs when the hot end or bed does not reach the set temp in an expected amount of time. For starters is it heating at all? What thermistor value did you select in the firmware? The PICO it's self will not be the problem. It is nearly fool and failure proof. Most likely it is s setting mismatch in the firmware. If you could post your configuration.h if possible.

My computer crashed and I had to reinstall the OS so I dont have the file anymore. Are you thinking I should reflash?
