You can detect belt slipage by using two rotary encoders, one on each pulley.
I’ve done this in robotics in drive reduction systems we put one encoder on the motor, and then, after a 9:1 gear reduction, put another encoder on the output shaft. Not using this to detect slipping but rather to account for play in the gears. Encoders are now dirt cheap. You can get AS5600 mounted on a breakout board, four boards for $6 on Aliexpress. > On Jun 6, 2025, at 11:50 AM, Dave Engvall <dengv...@charter.net> wrote: > > I apologize in advance for being off topic but need ideas (cheap and easy) > for shutdown of a machine (Jet 25” planner) when overloaded, eg the drive > belts are making high pitched sounds.
