On the topic of AC, other than for the most basic PLA bed sligners, you can quickly max out the DC power supply. High flow, high temp, high watts hot ends, large heat beds, large heated enclosures, high speed high power motors. At to that the DC conversion loss and safety limits, and you hit power constraints. That is why the bigger newer boards (eg BTT Kraken) support stepper motor voltage up to 60V, and often the heat bed is AC.
