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.

• 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:

• Start printing the parts
• Gather as much of the electronics as you can
• For the rest, find sourcing and note pricing
