Corgi Controller

This is a FluidNC CNC controller for use with external stepper motor drivers.

Note: More projects are coming so, please follow me.

Features

• Most connections use JST XH connectors. Only the connections that could exceed the current rating of those connectors are terminal blocks. (voltage in and MOSFETs).

• The main voltage input is reverse voltage protected. For simplicity, the main voltage is now 12V only.

• The USB can now power the ESP32 if there is no main voltage in. This can be used to set up the controller. Several things (0-10v, FETs, pendants) on the controller require the main voltage and will not function properly without it.

• RS485 is now fully isolated. It has also auto direction control, so only 2 I/O are required (TX and RX)

• Built in RJ12 for pendants and expanders like the FluidDial and Airedale.

• (8) Inputs

  • 3 pin XH connectors, ground, signal and SW_Vcc

  • SW_Vcc selectable between 5v and 12v. One selector affects all inputs

  • All have LEDs to indicate when they are activated.

  • Reverse voltage protection.

• (6) External motor driver connectors. Each connector has 5v and Gnd to make it easy to use common ground

• (4) 5V digital outputs

• (2) 3A MOSFETs
