Automatic fan control via i2c - 4 years ago
Hey all, I'm hoping someone can help me. I've built a simple i2c relay to run my fans using an i2c expander and a relay, I can control this with the Gcode below: To turn relay off: M260 A32 ; i2c address 0x22 M260 B170 ; write 0xAA (on) M260 S1 ; Send the current buffer To turn relay on: M260 A32 ; i2c address 0x22 M260 B85 ; write 0x55 (off) M260 S1 ; Send the current buffer I haby jifop - Firmware - Marlin
