For the M4 board, it shows the input voltage as 9~28V 20A. I currently run at 12V but I am thinking of switching to 24V. But I do not see a jumper on the board and a quick test shows the fans are not voltage regulated. If I up the voltage to 24V I assume I would need to switch out my fans. But for the four steppers would I need to make any changes?

I switch my printer to 24V and I am having a strange problem. My prints all lean along the X axis by a few degrees. Along the Y axis there are random shifts to the left or right but always goes back to center after a couple layers. For the Z everything is prefect, layer thickness is consistent. The weird thing is this is a delta printer so if a stepper is missing a step then all three axis would be effected. I switched back to 12V and everything is back to normal and printing correctly. I only switch to 24V to speed up heating the hotbed so I can live with it. But any idea why I would get these shifts? For the switch to 24V I only switched to 24V fans and lower the amps on the stepper as they where getting hot.
you are right, the Fans need to be switch,but no need to switch the steppers for most of the printers.
