Hi ti all,
I am currently working on the 3D printer project which should have three separate stepper motor groups. To be more specific, each group should be independent and should have four stepper motors plus a heated bed. Which leads to the question, is it possible to run those groups independently just with one Arduino mega board? Also should take into consideration what is the maximum power which Arduino can receive and control? Usually, 3D printers are using 400W power supply but because of three heated beds, I would need at least 800W. So if such a thing is possible to do, what will I need to do it?
