M571 to turn on Fan 0 everytime the extruder is started.
I'm trying to configure M571 to turn on Fan 0 everytime the extruder is started.
I've tried this but I think I'm missing something
M571 P0 F200 S255
I'm trying to trip a 5-volt small solenoid every time the extruder comes on.
The P parameter is the logical pin number, not the fan number. See https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins#Section_Logical_pin_numbers. Note, to use a heater or fan pin you have to make the pin free first before M571 can use it.
is this correct
M106 P20 I-1
M571 P20 F200 S255
No, it should be M106 P0 I-1 because it is fan 0 that you are disabling. The M571 command is correct.
I'm using 2 extruders and I need to lift my second extruder when it's not printing. So I'm trying to use.
How do I address the second extruder using this command
