switch on the printer. Got green led light from the power unit. Got red led to the hotbed circuit board. But, the merlin board will not bootup, and no power to the fan. Any suggestion?
What I have done so-far
Repeat Step 8, re-load the firmware. But, only one hotend fan is running. But, not the electronic fan.
Don't if anyone will find this useful. Just confirmed got a dead power supply. voltage output is only 4V.
