Pinecil - Tip Disconnected - molzy - 12-30-2020 Hi all! I just received my Pinecil today, and was keen to try it out. However, the tip does not heat up, and before calibration the display showed a very high temperature readout (420+ degrees C) while the iron remained at room temperature. Enabling "Advanced Options" => "Detailed Idle Screen" reveals that the tip is not detected by the Pinecil. The message "TIP DISCONNECTED" persists, regardless of which tip I insert, and the status of the locking screw. I have not tried to use the grounding connection as yet, and my power sources tested so far have all been USB-C PD. This issue persists upon updating to the latest release of the firmware, using the provided firmware flashing documentation. I believe this may be a hardware issue or user error, hence my post here. Has anyone else experienced a similar issue with their Pinecil?

Has anyone else experienced a similar issue with their Pinecil? I haven't had similar issues with Pinecil. It showed correct temperature values from the beginning (so starting from around room temperature). I only receive "TIP DISCONNECTED" message if I disconnect the tip. 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. |
