Warm (not hot) Molex.
I’ve got a 600 Watt AX power supply driving the 3DR. It’s doing so using one of the MOLEX plugs as it was the easiest female plug I could find.
The ATX side gets warm (the 3DR side does not) from the molex for about 4 inches down the cable, where it returns to ambient.
Thoughts? Concerns?
Sounds like one of the pins may have been poorly stripped and crimped. Are all lines equally warm?
Seems like it’s the 12v Ground…
Stop using ATX supply wiring for your printer. I used to want ATX and got a Gen7 board. The motor and heaters were on the same strand intended for hard disks with 2 molex connectors, that whole deal got warm. Now I have a flat ATXish server supply under the printer with 2 beefy 12V lines and grounds trimmed and in my Teensylu screw terminals. All other wire and shitty molex connectors removed from the PSU, it’s far nicer, and stuff is not getting warm.
Short answer: molex sucks!
I’ve been meaning to clean up the spaghetti…
@Bracken_Dawson - Underspec’d connectos suck. Molex has some beefy connectors if you want to spec correctly!
@Joseph_Chiu I use Molex Ten60Power quite a lot at work, they are really good. Other than that, every single connector from Molex I’ve ever encountered is crap.
