Made from laser cut 3mm acrylic and a 3mm CNC mill. You will need additional components
3 & 4mm bolts and knots
2 x 25mm (outer Ø) bearings
1 x ~12mm (outer Ø) bearing
1 x Timing belt (~5000mm)
3 x pulley (Should fit the timing belt)
3 x Nema17 stepper motors
1 x Arduino Uno
1 x CNC-shield
3 x DRV8825 stepper motor drivers
1 x Aluminium 14mm tubing (~2500mm)
4 x 3d printed 'Linear Bearings'
1 x 9g servo
Load this special version of GRBL down on the Arduino Uno - https://github.com/robottini/grbl-servo
This enables you to use a servo for the penlift.
The servo can be lifted by sending "M03 S50" to the machine and "M05" for resetting.
Software for streaming gcode:
https://github.com/winder/Universal-G-Code-Sender software.
The attached grasshopper script (.gh file) can be used to generate and send g-code to the machine. http://www.grasshopper3d.com (Input 2d geometry on XY plane in mm)
