PS_ON not working?

dc42

the 7.5a mini blade fuse blew. i wonder what would have caused that. i know i head a kind of pop when i tried to turn on my hotend.

Most likely you has a short circuit in the hot end heater or in the wiring to it.

@dc42

yes i discovered last night after i ripped my printer appart that there was indeed a short between the hotend wire and the heater cartridge. some kapton and a some silicone sleeves and all is well there!

@T3P3Tony i feel like im getting pretty close, i have come back to the original issue here is my M122 pre M80

not much has changed

joehsmash

i cant find any reference to M80/81 in the config.g file, and i dont see it defined any where else,

joehsmash

i have now added the M80/81 commands at the beginning of the config.g and again no change

M80 ; Turns on the ATX power supply
M81 ; Turns off the ATX power supply

joehsmash

i have also measured with my meter, that i currently have 3.3v on the PSON connector that is feeding onto the DUET. i assumed that the duet would just ground that pin. but irregardless of m command it still retains the 3.3v.

i also found a note in the forum from one of the duet employees that the GND isnt required so i have since removed it.

@joehsmash according to your config.g your supply turns on then the next line it turns off

joehsmash

@LeckieTech good catch, it still doesnt activate the psu tho

Topher

@joehsmash With that output, you can't really read it with a voltmeter unless you add a pull-up resistor. You could use any resistor you have between 1k-100k ohms and pull up to 5 volts.

Send M81 - you should read 5 volts on the middle pin.
Send M80 - you should read 0 volts on the middle pin.
(sorry for the horrible drawing)

Topher

@joehsmash I suspect that the output is working but isn't one of 2 things.

on the same ground plane as the PSU
not providing a strong enough ground to the PSU

joehsmash

I didnt test the board, i tested the voltage of the pson of the psu to which i have 3.3v

joehsmash

@LeckieTech i had a ground hooked up to the gnd pin on that header and it still didnt work. So i doubt that its a grounding issue. At least initially.

joehsmash

@LeckieTech so if i understand you correctly, you want me to pull 5v from the fan header and send it over to the pson pin through a resistor than from the pson to the meter and back to ground?

jjuuzzii

Did anybody find a solution ?
I got the same Problem!!

mitch

@jjuuzzii , I wired up my soft power control a little different.

What kind of PSU are you using?
