Bart Dring's 6x CNC Controller is an ESP32-powered, FluidNC-compatible CNC controller board with support for 6 external ...

While the required external Ls and Cs (of course) vary wildly from topology to topology and chip to chip, (almost) all use exactly the same basic two-resistor network for output voltage programming ...

It’s interesting to note that while our conventions have changed in schematics by having negative ... have finite channel sizes and will act as resistors versus dead-short circuits.

You know what’s cool? Using your engineering knowledge to solve problems that you have while building something. This is exactly what [Reinis] did when his 3D printer’s endstop wasn’t working.
