Bed not heating
Yeah I feel ridiculous asking this seeing as there are two other posts about it but I cannot get my Keenovo 1500w bed to heat up. Im in the process of setting up the V-Core 3.1 500mm with Octopus V1.1. No red light on the SSR despite trying to imitate linked wiring posts...maybe im blind. Photo of wiring attached.😕

I should add that I am following the klipper configuration documentation and I am sending 50 deg celsius to octoprint.
Are you using Rat-OS?
I noticed you have stacked the terminals on your PSU. I would change that to distribution blocks as they make a more reliable connection
yeah using rat-os. appreciate the advice i will get some blocks. continuity is good though.
Ok, you are using Rat-OS - so when you say you are commanding via octoprint. Do you actually mean octoprint or do you mean via the mainsail interface?
Mainsail I think
i set target to 50 and hit enter
Ok, and when you set it to 50, what happens? Does it time out and throw an error?
State changes from "off" to "100%" and when i hover my mouse over it there is an avg % that slowly ticks up to 100% and then it throws "Klipper reports: SHUTDOWN
Heater heater_bed not heating at expected rate
See the 'verify_heater' section in docs/Config_Reference.md
for the parameters that control this check."
Ok. Did you use a multimeter to confirm that bed out is producing DC voltage?
no dc voltage at relay or bed out
Did you confirm you are getting DC in the bed in?
4V is what it reads
thats got me scratching my head a bit
If you disconnect the wires from the board and test, is it still 4v?
I disconnected all of the power cables and now the voltage is 0 essentially
Well, not sure what is going on, but sounds like your PSU isn't working correctly?
maybe i just need to adjust the output
there is a small white screw i assume it is a pot
what should it be....24V?
yeah bizzare the voltage adjust isnt doing anything...ill be bummed but also relieved if this is not a me problem
Yes it should be 24 volt DC output from the PSU. Are you in a country where the AC is 120v and you forgot to change the PSU to the 120v input?
you know that is possible...i am in the USA and the voltage is 120v.
#!@$ #!#@ #!@#
yup that was it what a dummy I didnt even think about that "obviously"
thank you for assisting me an my incompetence
