Need some help on MOSFET for Heat Bed/ Config file

Darren_Anton_SW · June 14, 2017, 9:49pm

So I had it setup with a SSR but after 2 years it burt out, I think the 2.5 Big mosfet on the card also went out, shows 12 volts on it all the time.
(24 Volts Heat Bed only)

So rechecking the docs I see there is now a way to run in SSR mode

So I got this Wangdd22 3D Printer Parts Heating Controller MKS MOSFET for Heat Bed/Extruder MOS Module Exceed 30A Support Big Current
from Amazon

To replace the SSR If I read right it’s better then a SSR??

I set it up on pin 2.5 and the ground next to it
(had it on 2.4 but that is the cooling fan)

But having a hard time understanding the code in the config file …

Here is what I have (I think all wrong)

the only way I can get it to work was to set “temperature_control.bed.heater_pin 2.5”

does not seem right…

Its the “Switch” part I’m having problems with

Seems it messed my code all up… Can not seems to add the config file here… How does one do that?

Post it on pastebin.com and give us the link, is the simplest method.

Note : to get to the forum you should have had to go through this page : http://smoothieware.org/forum-welcome-mat which explains the rules of this forum, but also how to post config either using tags, or pastebin. Read it.

Ok a few comments based on your config file and your email.

You seem to be confused about temperaturecontrol and switch, they are very different modules, see the documentation for each
You are rewriting your config file from scratch, that is a horrible idea. Please use the example config file and modify it *as little as you strictly need*
Yes there is a list of all config options, see the home page
All your questions so far have their answer in the documentation, I recommend you read the documentation
