Got the Mean Well LRS-350-24. Printed a PETG cover on the other 3D printer for the terminals and holder for the fuse switch. Bypassed the Heated Bed MOSFET. Wired everything back up.
Recompiled Marlin with a bedtemp of 120 (realizing maybe it should be 110 maybe? When they say the bed can go to 110, is that with a 10-degree buffer? Or really should it be 100 max?)... anyway, i can get to 80-degrees for the bed now for PETG. Takes a long time. First attempt at PETG and I realize I messed up my Z-adjustment. Will play with it tomorrow and readjust.
And by the time it gets there, zoom in and take a look at the corners of that flex plate. Heh. Yeah, don’t think they will do 80C bed temps. The magnets aren’t enough to fight the thermal changes. Maybe you need glass for that hot.
You can just see my metal Z coupling.
I don’t trust this printer with just Octopi watching and mic/speak to hear alarms... I did get a bed temp runaway at about 103C when trying to get to 110. No idea what that was about, but beep is loud and doesn’t stop. :)
Oh well. 2am. Waaaaay last bedtime.
I ordered a 310x310 glass plate. I'm having warping issues like you are. Not quite as bad on the corners, but they're at lease a layer height off in various spots around the bed. I've turned mine upside down and am using hairspray.
I got 14 AWG. What are you using? I think I have some 16 AWG that I use for RC purposes so if you think 14 is kinda big that is kinda where I was when I was ordering, "should I go smaller? Nah, bigger is better!"
I was thinking about the same thing when reading over the notes on the psu. I may just use lighter guage from the the mainboard out to the XT60 and then go from there to one rail on the psu. Then just go fatty 14 from the mosfet to another XT60 and then on to another rail.
I'm running a BTT SKR 1.4 Turbo in this and my other printer. The way I have it set up in the other printer has the same Mean Well and it runs a single rail to the "in" on the SKR and then just goes out from the heated bed port to the bed. That's basically the idea I've outlined in the posts where I describe the upgrade.
Ohh wow! I like your design for the mount/enclosure much better than mine! Would you mind sharing the STL?
