Firmware for Sanguish
Sanguish Home ----- Build Sanguish ----- Use Sanguish
General Guidelines
The main changes that need to be made to firmware in general are the following.
1. Change the motor enable pins to non-inverting ie. active high logic, Dont forget. 2. Change the step pulse delay if needed to at least 10us. 3. Change the power on control to active high. The power on pin only controls the stepper driver power relay. 4. Add Pin assignments if needed
Repetier
Repetier was tested early in the Sanguish Beta test program and works well. There are settings in the config.h for power on logic, enable inverting, and step pulse delay. Below is the Pins.h entry I added to define the pinout.
