I am having an issue with heating the filament and decided to use a slightly higher temperature. However I noticed that the temperature monitor reports that the nozzle never seems to reach the desired temperature. For example, when set to 180 the monitor says 178, 190 only gets to 182 as does 195, and selecting 200 degrees seems to lock the software up, both in Manual Printer Control and while printing a file where I have changed the Slice filament settings.

The effect I am seeing is that the diameter of the filament being deposited on the bed is about 33% of that being fed to the nozzle mechanism and it curls around the nozzle rather than depositing correctly on the bed.

Perhaps the nozzle clogged with old filament?

What type of printer, control board, etc? With those readings, and the software issue, I’d think bad connection to either the sensor, or the extruder. The low extrusion rate/curling is likely due to a lack of sufficient heat to melt the filament.

I think you are correct in your diagnosis. The printer is the V3 , I haven’t checked the motherboard. I have taken the print nozzle out of the printer and I remembered that the heater did not fit fully flush with the block when I first assembled it - it is about 2mm proud of it and I couldn’t get it to go any deeper.

I can’t extract the heater from the block.

Also I am not sure if the end of the heater should be concave.
