Nozzle doesn't reach temperature and not feeding PLA

The nozzle on my Snapmaker 2.0 doesn’t heat up.

During a recent print, PLA stopped being extruded. I thought the nozzle was jammed but I realized it was not heating up when I tried feeding new (straight out of the package) PLA through the manual controls. The nozzle never reached 200C and was cool to the touch.

It feels like the gears are grabbing the PLA, and I can see the marks when I reverse and unload it …

Does anyone have any suggestions?

Thank you.

Stays only the noozle cold or the heat-block also?

I think it was just the nozzle.
The bed was getting hot.

Toolhead? Dual or single extruder?
Machine?

Jumping to conclusions I’d say the heater element is either broken or the connector got loose. Check your connectors, and if you have, cross check with a replacement hotend.

For more help we’d need mor details - like the questions asked by Campinorod and xchrisd.

Need to know what’s happening on the touch screen.

Snapmaker 2.0 350.
Single Extruder.
The screen showed normal operation and the Luban software showed no errors and it looked like it completed the run…

I unplugged and reseated the cables and rebooted. Things seem to be working now…

If this issue repeats, check your connector of the hotend and if the thermistor is in the correct position inside the heatblock.

Do you have a diagram/ schematic for the thermistor?

Not sure what i should serve you..
