Works fine on this end. Flashed the firmware I uploaded for you. Heated the bed. Attached a screen shot, I went to 40 and realized you wanted 70 (pretty hot, normally use 45 for pla). Lets see your temp graph, mine is set at 10min.

Are you sure you have a 30A power supply attached? If it isn’t at least 20A it won’t heat up and will fail for taking too long.
