FluidNC Config Files - bdring/6-Pack_CNC_Controller GitHub Wiki

You must create and upload a config file to FluidNC that describes your machine. The FluidNC wiki has very detailed instructions on how to do this. There are dozens of example configs in this folder. It is best to start with one of the examples that is close to your machine and modify it as required.

Stepping

The 6 Pack uses i2so expansion chips for the stepper motor signals. You must use I2S_STATIC or I2S_STREAM as the engine: type. See this page of the wiki for details.

stepping:
  engine: I2S_STATIC 
  idle_ms: 250
  pulse_us: 4
  dir_delay_us: 1
  disable_delay_us: 0

Modules

The fifth module (on right side) uses i2so pins. This means you can only use use it for digital (no PWM or analog) outputs.
