If you've followed a few posts you'll see that some of us have had issues with the power supplies that were sent with the printer. I'm feeling that my current situation with getting thermal runaway errors is because the power supply cannot keep up with the movements of the printer, run the fans, mainboard, and LCD, and keep the hotend at the correct temperature. I've talked about it but now I'm at the point where I need to build this to get the printer to work.
Here's the BOM:
Mean Well LRS-350 24v
15A 250v switch/fuse/mains connection
14-16 AWG wire
Here's a render of the case I'm printing to hold the power supply and provide cover for the terminals.
Thingiverse has exploded so I'm not sure where to put my STLs for the moment.
Currently my materials are on order. They should be here this weekend so I'll do the full write up then. Essentially, we're going to put the ground, neutral, and line from the switch block to the corresponding terminals on the power supply. The supply has several rails for 24v out. With 14-16 AWG wire you should only need to run a pair over to the mainboard. The connectors listed are a convenience factor. You'll run the wires internally from the board out through one of the holes for the barrel connectors. Then you'll solder on a connector. The wires will exit from the enclosure and go a length before terminating to the opposite connector. The mosfet system for the heated bed will no longer be necessary and can be removed. The power for the heated bed will plug into the mainboard where the current wires come off to the mosfet.
When mine gets here I'll clean up the STLs with better measurements. This really holds true for the opening for the switch block. I might put some feet on it or make it look cooler somehow. Then I'll post a follow up showing each of the steps.
