The bed consumes about 700W, so it is heated very quickly (2minutes/100C). I'm waiting unnecessarily for the extruder to warm up.
Or I have to edit the g-code manually, which is annoying.
Heatbed heat at 100C in about 2 minutes. I have a 12V bed MK3 200x300 connected to 24V. I control it with an external mosfet (STH315N10). The current consumption is 26A
Sometimes the desired temperature reaches the bed faster, sometimes the extruder.
