so here is the deal .. i have an atmega2560 based board for the vellman vertex k8400 3d printer..
power went out when i was flashing the firmware - (NOT my printer.. a loaner of sorts)
so now it dont work and with the usbport built on it wont recognize what device it is. to attempt reflash
*usb does find a device tho.. so its breathes a bit*
i am a noob to arduino but it s on my list. .with the broken printer tho i am rushed and not in the mindset to the depth of these forums and docs and etc..
so i need help just to make it live.. so i can take the atmega2560 i bought off amazon to use as a jump start programmer to force the new firmware or old firmware on the printer and make it go
i got the new atmega2560 standard board flashed with the arduino as isp sketch and it talks..
but when i push the firmware or boot loaders to the printer
