Pencil Plotter
Project initiated May 2021.
Probably going to start with Andrew Sleigh's v3 design of pencil plotter and improve from there if I need to.
Required Materials
- 2 NEMA 17 motors
- 2 GT2 timing belts
- 2 8 mm linear rods
- 4 8 mm (8UU) linear bearings
- 30 or 40 tooth pulley for x-axis timing belt
- 20 tooth pulley for x-axis timing belt
- Large idley pulley for x-axis timing belt
- 2 small idler pulleys for y-axis (not the larger Openbuilds pulleys)
- 5 mm rods for pen lifter
- Plenty of M5 and M3 hardware!
- Large v-slot gantry kit (I got mine direct from China)
- Tower SG90 Servo motor
- Some GT2 belt clips, such as cable ties, or these nice removable clips:
Next steps
- Start printing the parts
- Gather as much of the electronics as you can
- For the rest, find sourcing and note pricing
