Descrição
This is the latest version of my pen plotter project, updated to use aluminium v-slot extrusion for a more stable x-axis.
For easier versions see these things: https://www.thingiverse.com/thing:4037180 and https://www.thingiverse.com/thing:3986756
Full details of the project are on my website and in the Github repo
Support my work!
If you like this project or would like to say thanks, you can buy my plotter artwork from https://penuppendown.square.site. I'd really appreciate your support :)
2020 or 2060?
Note, there are files for two different versions of the plotter her, one that uses two lengths of 2020 for the x-axis, and one that uses one length of 2060. The 2060 files are more recent, and have some nice touches like an integrated electronics housing, but otherwise, they are very similar. I would suggest you make whichever one is most convenient. If you have 2020 lying around, use it!
Improvements over earlier versions
- More stable x-axis (and so less drooping of the pen at it's furthest y-extension)
- Much quieter motion on the x-axis, after swapping out linear bearings fora wheeled gantry
- X-axis can be screwed down to a solid base for greater stability
- Improved brackets for timing belt and linear rods on y-axis so belt can be more easily removed or tightened
- Simplified and more compact pen lifter
- Housing for Arduino and CNC shield can be removed or re-modelled easily (e.g. to fit a smaller Nano-based CNC shield)
- Base has a rebate to fit a 60 cm cutting mat, to allow easier alignment of paper for plotting
Other parts you'll need
- 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: http://www.thingiverse.com/thing:2354961
(In the UK, I'd recommend Ooznest for all the materials you need to buy.)
