Think of GRBL as a signal generator. If you get proper stepper drivers like Gecko drivers they will work with GRBL. If GRBL does not work out you can always upgrade to MACH3 or other CNC controlers. (Cost involved with GRBL is only an Arduino Uno + some time.)

I am building a large cnc for 2400 x 1200 sheets, using nema 34s.
Really interested in Arduino and GRBL but have too much current draw I think.
Do you have any suggestions? Thank you and good luck
