5amp Vs 30 amp Power Supply

I plan to build a cnc router with my MPCNC. I might do some 3D printing in the future. Do I need the 5 or 30 amp power supply?



Also would like to do cnc laser as well.

The 30A is only needing during 3D printing if you add a heated bed.

It would come in handy for Loe69’s Laser though, That’s how I do it.

Thanks. I ordered the 5 amp.
