Make sure that you have MAX_BED_POWER set to 255 (which normally should be, since it is the default).
Other than that, I found that the following measures help speeding up the heating of the heat bed:
Other than that, I found that the following measures help speeding up the heating of the heat bed:
- Put some heat insulation underneath your heatbed, e.g. a layer of cork sheet.
- When heating up, start with a layer of corrugated cardboard on top of the bed and take it away when getting towards the target temperature.
- If you can, increase the voltage of your powersupply by 1 or 2 volts. (e.g. increasing from 12V to 13V will give you 17% more heating power.)
