Lo and behold after 9!!!!! hours of no go, it works.
A managed to get it to accept the firmware.
After reading this.
"As RepG does a few retries before it timed out again in the log, I just pressed the reset button with a pen tip and it started flashing."
I thought , hey i try to press the resetbutton every 2 sec until the green light start flickering.
So i pressed download, pressed reset,1, 2, 3,4 ,5 , 6 times and then it started to comunicate.
Now i have 2 lines in the LCD and the heatbed is warming up , as expected.
Best regards, Hasse.
