Meanwell power supply 350W PRUSA CoreOne mount

Back ground

In case you are like me, don't have the CoreOne Black Power supply, but have a better power meanwell power supply LRS-350-24 and want to use it for your coreone printer.

But why don't I have the official prusa black psu? because my coreone is a CoreOne upgrade kit, the black psu is Not included, and it's quite expensive to buy one + international shipping + tax duty.

I upgraded my MK4S to CoreOne using the upgrade kit.

But why don't my MK4S have a black PSU ? because my MK4S was upgraded from MK3S.

and at the old time a silver Silver PRUSA PSU was provided. and it's broken (silver is bad quality, that's why they change it to the black version). I have been using meanwell psu (350W 24V) for MK3S and MK4S for many years.

HW required

if you want to power down power panic function, the small PCB from the old PRUSA silver PSU is needed.

if don't need that power panic function then this part is not needed. I installed that pcb for my MK4S and this coreone.

 M3 hex socket head screws 8mm 

M3 heat insert

M4 8mm screws to mount the printed part on meanwell psu

M3 pan head screws X 2 for side mount since the screw head is larger it 's better than socket head.

Warning

Make sure you know electricity when handling live wires and parts, since obviously 120V and 220V voltage is dangerous and can cause life threatening injury or death.
