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.
