On my LCD screen the themperture of the left nozzle just shows 0/0 while the right one shows the coreckt room temperture(29/0). I have no idea why whis happens i already checked the conecktions on the mainbord and on the extruder bord. Can anyone help me find the problem?
I take it you have 2 nozzles.
Have you installed the firmware for 2 heads?
Check the CTN circuit. The LCD displays 0/0 when there is no CTN connected.
I have the current firmware for two heads. Everything is wired as it should be i checked it twice.
Unplug the NTC from the controller board and measure the resistance between the contacts of the plug. It should be around 100KOhm.
If you can’t have a value do the same on the terminal where the thermistor is plugged (circuit board above the heads). If you still get no value (infinite resistance) then your thermistor (or its connexions) must be broken.
Is it a problem that my NTC is around 115 ohm?
