the difference between closed and open must be according to the 3.3V logic. high ≥ 2.0V low ≤ 0.8V

connected V = 5V G= GND S= Signal pin

The voltage between G and S must be in the range high ≥ 2.0 low ≤ 0.8 depending on whether it is closed or open. Is the LED on and...


Then you have a problem with the sensor

Don't buy a new sensor. Buy 3DTouch. It's super

The malfunctioning fan, remap the fan pin and use the external MOFSET module https://www.aliexpress.com/item/32816837677.html?spm=a2g0s.9042311.0.0.27424c4dutw2hB

Pins 1.25, 1.26 and 1.0 cannot supply the fan directly, so a module with Mofset is needed. If it is a fan on the heatsink, or a fan for the...

FAN0 (pin2.3) is predefined for fiber cooling and is switched by g-code from the printed file. That's probably why it doesn't sleep at 50 ° C Use pin 1.25 to...
