Turn ATX PSU on with GT2560
Posted: Sun Feb 09, 2020 2:23 am
I want to use the M80/ M81 command to switch a ATX PSU on/ off.
Ihave the GT2560 Rev A+ board that came with my I3 pro b.
What i managed so far:
I chganged the Pins.h so that pin 13 wich is the only pin off that i know the location on the board( since i used an BL touch in the past and this is the Servo pin) is now the PSU_ON pin. I disabled the Suicide pin and the Kill Pin in Pins.h.
Now it seems to work (kinda)
When i switch on /off via M80 /M81 i get Zero/ +5V on this Servo pin.
So from i read to control the ATX PSU i need to pull down the Green Wire on the 24 Pin Conncetor to ground.
WHile this works great with a wire stuffed into the connector, i dont know how use my 5V "signal" to switch it.
Any ideas , or even maybe your on Setups are welcome.
Thanks in advance
