Comment on [Troubleshooting] It's the clog guy again - temp readings are bad!
tristan@aussie.zone 6 months agoWell the reason I asked about the hotend was because of you’re using the little glass bead version of the thermistor, and the hotend has the hole to feed through, I had an issue on an old Frankenstein ender where it wasn’t touching the metal inside correctly… As it heated up, it would kind of move the thermistor away from the metal. I solved this by putting a DIY metal shroud on it that held it in the middle while touching the hotend all around. I also used thermal paste to make sure there was no gaps.

I see; though, a thermistor not making good contact with the heat block would imply the heat block is hotter than reported, not the other way around.
This glass thermistors are a nightmare. I kept accidentally ripping the leads off mine. During this whole debacle, I treated myself to a fancy thermistor that is built into the end of an M3 bolt - it screws in to the hole meant for the grub screw that normally keeps the glass ones in place.
