Cartesian Plotter v3
by Thingiverse
Last crawled date: 6 years, 1 month ago
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
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)
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)
Other parts you'll need
2 NEMA 17 motors
2 GT2 timing belts
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
5 mm rods for pen lifter
Plenty of M5 and M3 hardware!
Large v-slot gantry kit
Servo motor
