Clear all code from Arduino

Mostly Printed CNC - MPCNC Advice

Hi Everyone,

I was learned very basic programming with Arduino for short time and I decided turn it into MPCNC so I want to know how to clear code from IC before install GRBL.

Regard

If you flash new firmware onto the Arduino, it will erase the existing firmware before writing the new.
