To trip the limit switch, the printer simply lowers the z-height until the hotend “probes” the bed, defeating the magnets and breaking the current. Presto! No switches or P.I.N.D.A. probes.

Essentially, each pnp transistor compares a reference voltage on the npn emitter with the voltage across the lower limit switch circuit resistors R4, 5 and 6, directing current to the led if the limit ...

The most common limit switch is the single-pole contact block with one NO and one NC set of contacts; however, switches are available with up to four poles. Limit switches also are available with ...
