This is a simple belt driven XY plotter using sliding elements for both X and Y axes. It can move relatively fast, 300-400 IPM (130-170 mm/s). The Y axes sliding elements are driven independently which allows larger X spans without loss of accuracy.
- Axis travel: X17" / Y11".
- Assembly time: approx 2-3 hrs.
- Accuracy: ~1/32"
- Original version has accuracy issues due to backlash in jaw motor coupling.
- New and improved version has pulley directly on the motor, eliminating backlash
- Structural Kit
- Linear Motion Kit
- Electronics & Motors Kit
- 24" angle lengths
- XL540 belts
Whatever happened, Happened
A larger version of the plotter with work area 17"x17" was used for Daniel Palacios' art project: http://danielpalacios.info/en/whatever_happened
