Revision to Choosing the power supply
|* A 24V bed heater takes half the current of a 12V heater of the same power. So you can go to double the heating power before you need to use an SSR to control the bed heater. This means that 24V is generally advisable for printers with a bed larger than about 200mm square unless you use an AC mains voltage bed heater. See [[Choosing a bed heater]].|
|-||* You may need to use 24V to achieve the travel speed you want without losing too much torque. See [[Choosing stepper motors]|

|* If you intend to use the resume-after-power-fail facility, a 24V supply will be able to power your stepper motors for longer before the voltage falls too much. This makes it more likely that it will be able to complete the power fail script.|
