Hi , I am building a USB control box for a Gantry type CNC router with stepper motors.
I have seen both being used with an Arduino Uno , the GRBL "Gshield" and the more popular "CNC shield".
The main thing I see is the "CNC shield" has replaceable Stepper Motor Drivers and the Gshield has the Stepper Motor Driver soldered to the board.
I like the idea that if I screw up and fry a Stepper Motor Driver that it can just be pulled out , replaced and back to cutting ( yes figure out why it fried first)
Is there anything else I should think about ?
PS....it seems the Shapeoko community uses a Gshield , and was supplied with the Shapeoko kit
Thanks for your ideas
