Power on for flashing firmware ?
Posted: Sat Apr 25, 2020 3:23 am
Hi there,
I got a new GT2560 from geeetech to replace the original one that was defective. I connected :
- the old and new motherboard
- on any of my 3 linux PCs
- with 3 different USB cable
and none of the computer is seeing a USB connection (like in "dmesg -k").
It was just the board and a computer. The printer itself was elsewhere.
I did Arduino programming in the past, and just the 5V USB power was enough but I'm now coming to wonder the basic question if i should also power the motherboard with the regulard 220 V plug ?
. I prefer no to try to not roast my computers with a potentially defective manufacturing before being sure i have to do it...
Thanks for any of you already having USB plugged the motherboard to flash it to confirm or not.
