@po3plestorm missing a M584 by any chance (I fell into this trap a few week back)

M584
M584 assigns motors? I cant get the nozzle to heat up

@po3plestorm yep but it completes the setup I had exactly the same issues.

@dougal1957 I did this but still no change

@po3plestorm I also just noticed none of the fans work either, always on and the pwm all dont work

I also measured a 12v voltage on the output and tried with multiple different heater cartridges. still nothing, the light does turn on for heating as well.
When you measured the voltage did it turn on and off along with the heater activation?
You're using E0 heater right now, can you change over to E1 heater port and change the config
M950 H1 C"e0heat" T1to match? -

Are you sure the blade fuses are intact? Have you tested them with a multimeter for continuity?
-
@phaedrux the e0heater has a voltage when the heater is activated and was tested with multiple heater cartridges. I just checked all the fuses with a multi-meter and no problems there.
I changed the config to
M950 H1 C"e1heat" T1and now its got a voltage on the e1 heater but still the same problem.
and
M950 H1 C"e0heat" T1was what is was at before

Supply voltage: min 14.2, current 14.3, max 14.4,
The supply voltage seems strange. What does a multimeter read for the PSU output voltage?
I also don't understand how there can be a voltage present on the heater outputs but no response from the heater cartridge itself.
Is your system supposed to be 12v or 24v?
-
@phaedrux my power supply is running 12.22 volts and so does the heater cartage. and my heater cartrage is running 115ohms.
Like I said before I had this issue with the non genuine duet as well but I assumed I broke the mosfet for some junk from a cheep board, but this one is a genuine with the exact issue.
-
How many heater cartridges have you tried? Are you using extension wiring for them?
-
@phaedrux i tried 3 different cartridges that were brand new, that I checked the resistance was all around 100kohm +- 10. I also tried putting just straight wires without the ferales. I just now checked with a mutimeter in series to measure current and it just read 0amps.

As a sanity check, since the bed heater is working, can you move the heater cartridge and thermistor to the bed heater terminals and command the bed to heat?
And yes, move the M584 earlier in the config.g it needs to be before any commands that reference a defined axis anyway.
Can you also send M98 P"config.g"?
You said before the fans were working, but now they are not?
And the fan fuse is intact?
Do the fans work when connected directly to VIN?
Do you get any voltage readings off the fan headers? -
@phaedrux okkkk I think I just have a bunch of bad heater cartrages, I plugged the cartrage and the thermistor into the bed pins and it doesnt work, so I think I just have a bunch of bad thermistors. thats unreal if it is true.

@po3plestorm
and there is the m98 commandM98 P"config.g"

@phaedrux @jay_s_uk Hey just wanted to thank you guys for helping me out. I found the problem.
the entire pack of heater cartridges I have are just bad. I got a huge pack on amazon and I just tested them on my room mates 3d printer and not a single one worked. The resistance on them is totally fine, they look fine, but all 8 of them in the pack are just bad, no clue how.
Im so angry but at least I got down to the bottom of it.
