Arduino CNC cum 3D Printer
Prerequisite
You can make it at small hobby project level(same as i made) or at a higher level.
For hobby level you'll require around 3 cd-rom drives while for higher levels you can utilise 3 dot matrix printers or buy rods and lead screw with motors of your desired choice according to your planned size.
Universal components include stepper drivers, 12v 5a power supply ,a laptop and some prior experience with arduino.
Construction
1.Dissasemble drives or dot matrix printers and keep aside the stepper motors and their frames.
2.Assemble the frame according for X,Y and Z directions.
3.Connect the wires and then to the stepper drivers which then should be connected to arduino.
4.Connect Power Supply of 12v and don't join 5v to arduino from stepper drivers if connected to pc.
Software
Install the Grbl software from my git.
Run Hex installer and install Hex file into arduino.
Run Grbl controller and connect your arduino on the correct port.
Try moving your steppers using the arrow keys.
Upload your design on onlinecam, export the grbl code ,upload in software and enjoy.
