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.
