I got a really cool sensor that will be going into my next printer design. Got a special fancy force sensitive resistor that has a thruhole in it. Normally meant for bolts and strain sensing, but from fooling around with it with a multimeter, I got consistently good signals at low force. Meaning it should be effective for a tap probe.
Working on design hardware now that if it works, would make for tap upgrades being trivial.

@npub1yrl…8gpm @npub12at…me5y use iglidur I say.
It's hard like ABS, doesn't creep, and is like the slippiest filament you can get.

@npub1yrl…8gpm @npub12at…me5y weird question. Is your sensor wire running alongside your steppers and hotend power? And how long is the run.
My observation is you can see weird EM noise if the thermistor line isn't shielded. Standard 100k thermistors aren't as affected by it, but with a PT1000 it was super obvious. I was picking up radio waves on the thermistor lol.

@npub1yrl…8gpm @npub1u5p…uljc @npub12at…me5y I had it happened where it would just jam up or kink up in the extruder.
I was also trying to go stupid fast so ymmv.
PetG when I made it crosslink at 280, I had to scrap the nozzle, I only ever got crosslinked PETG out on a high temp nozzle. It more burned than melted out at 450 lol.

@npub1yrl…8gpm @npub12at…me5y on my direct drives, I had to undo the idler tension all together. Or feed it in and then yank.
Though a few times I got a clog out with something called the force feed. Involves jamming a 1.8 mm stainless steel wire down the extruder. Then It either flowers clean or I could cold pull

#caturday look at this polite little girl, she's been hanging out in her cathouse all morning since vacuuming happen.
Not even scared, just looking interested.
