Motors do not react

I have been here since beta stage, but have not been cutting anything since December. Just upgraded from 0.99 to 1.10
firmware upgrade went ok and ground control looks fine, but I cant get any motor to move
I have verified that there is power to the arduino and pcb, connection is ok too… What’s next?

Connected on port COM3

PCB v1.1 Detected

Old position data detected.

Please set $12, $13, $19, and $20 to load position.

Grbl v1.00

I will see if I can figure out how to Wipe Eprom
