Within the last three weeks, from printedsolid...

The finger test works, but it takes a lot more force than the v2 I also have. Even setting the sensitivity to the lowest value it takes real force to trigger it. Doing a probe repeatability test shows it's only accurate to 0.2mm across 10 hits.

The printer I built is pretty stable, I was able to calibrate it using paper and the V2 and get really good prints still so I doubt it's the hardware, especially since I can swap a V2 on and use the default sensitivity and get repeatability in the micrometers...

I've been using a V2 smart effector for years and it works great. So much so, I sold someone on a new printer with a smart effector so ordered one.

What I got is useless crap. This new resistor arrangement is about as sensitive as old junk FSR mounted to the bed. I can watch the effector tweak as it literally crashes into everything, bending a three point mounted 3/16 aluminum plate as it does so.

I swap the not useless smart effector on and it'll calibrate with reasonable values, nothing else changed. Swap the new 3.0 over and I'd be better off calibrating manually.

Can I get a V2 smart effector still? Or do I need to make my own now?
