Pinecil - Tip Disconnected

[molzy]

I have a feeling you may have some soldering problem inside, so it may not have connection of temperature signal pin for example.

Thanks VaZso!

I opened the unit and quickly found a dodgy looking connection of a resistor (R2), which doesn't appear to be anywhere near the tip detection according to the schematic. It's for grounding after a power regulator associated with the USB-C VBUS. The rest of the components have been populated, and I can't find any other obvious soldering imperfections.

I'll repair that connection and give the unit another pass when I next have time, and if I don't find anything else, I'll open a warranty case to see what I can find out.
