Ive recently bought myself a Kobra 2 pro. After first assembly, i powered it, turned it on and it beeped 2 times, started loading and right before loading up, it powered off. I checked the voltage switch, the motherboard, all the cables and everything seemed okay.

A week later i randomly decided to power it back on…

And it successfully turned on without any problems. I calibrated it, printed myself a benchy and turned it off.

A couple hours later i decided to print myself another model, but it didnt turn on.

With the support, we came into conclusion that the power unit isn’t producing enough power ( this would explain the printer turning off after some time )

If anyone had/has the same problem as me, please send your solutions. I am currently waiting for the power unit to be delivered, but before replacing it, i want to make sure that i’m not just wasting time.
