Hi,
I'm new the cnc world and have decided to build my own laser cutter.
Having watched numerious how to videos on Youtube I've noticed that CNC Router builds tend to use dedicated stepper motor controllers with a hefty power supply whereas Laser cutters from what I can tell just use a cnc sheild that then has an A4988 Stepper Motor Driver plugged into it.
Would I be right in assuming that routers require more oomph hence the larger power supply and dedicated Stepper Motor Driver Board, or could the stepper motors for a router be powered/controlled by the A4988 Stepper Motor Driver plugged into the ardunio shield?
Would a laser cutter benefit from a dedicated Stepper Motor Driver Board?
What is the general concensus on such things
Rgds,
Stuart
