      I'm trying to set up stall detection on my Duet Wifi due to some rare layer shifting that has been occurring late into large prints. However, I'm having a lot of trouble dialing in an S value that works (for example, S2 will give constant false reports but S3 won't measure anything even if I yank the bed around by hand during a print). I've tried adjusting motor current, jerk and acceleration but I'm not getting any real results.

      In the wiki page for stall detection it mentions that it tends to be most reliable at faster speeds, but doesn't give any real indication of what range of speeds will usually work. I'm printing primarily PETG, so I'm generally maxing out at 40-45 mm/s for print speeds (and slightly slower on outermost perimeters). Is there something I'm missing that I could tweak to get more accurate stall detection, or am I somewhat SOL with such a low print speed?
