Laser questions

So it's just the fan0 mosfet that is blown.
-
Hopefully. What's it look like. Where on the board is it? Sorry I'm not super familiar with it all
-
It's the 3-pin device labelled TR5, close to the fan voltage selector jumper.

thats a little small but I might be able to manage it. I don't think I've soldered much smaller than that. Also why would the other things act up per my above post. Not to mention that in the web gui, I know only see Fan0 and no fan 1. under the misc. area at the bottom. Did I change something in the config file to remove it?
-
Also is there a way to make header P1 the default vs P0? If not I will use P1 for now until I get a mosfet for P0

Which fans you display in DWC is selectable in the Settings/User Interface page.
I suspect you have a poor connection in the bed thermistor wiring, perhaps in the crimp connection where it plugs into the Duet.

Perfect, I was wondering how they went away to begin with. either way thanks for the help on the user interface page. That worked out great. Last question because I want to make sure I get the correct Mosfet, do you possibly know it's part number or have a link to the ones used on the board?

There is a wiki page giving connector and spare part numbers.

Thank you, I didn't even think to check the wiki for something like that. while I wait for the mail. I'm using another header.
I wonder if I could use a different header all around. Do you have any suggestions? I've seen talk about using the extruder… I think it was.

Got the MOSFET installed, I now have fan control again… it looks a little rough but it works.. Gah those things are small.
anyway, still have an issue with the fan not turning off when 12v psu connected to 12vin on module and ttl connected to fan header. If I don't use the TTL it works via fan to pulse the laser on and off.
