Get a better heater. Compared to spec, you're heated bed is producing up to 25% less heat than it's suppose to, and nearly 50% the heat other heated beds (1-1.2 ohm) produce. The Alumnium core acts as a giant heat sink. This works for you when you want even heat for your entire bed...but bad when you're already struggling to get it to temperature let alone maintain it.Quote

The heatbed has 1.9 ohm resistance. 0.3 more than they say in the datasheet.
