Color changing gondola V0.5

thingiverse

The design is based on ZarPlotter's gondola. To achieve the desired movement, a servo will be used to move the gondola up and down. The other servo controls the rotation of the pen holder, which holds four pens. According to this design, this servo must be activated three times to rotate 90 degrees the pen holder. A stop piece locks the system in place so the pen holder stays where it is placed. Springs or elastic bands are needed to keep the moving parts against the pen holder. The software is still being developed and is based on the great work of Rick McConney, available at https://github.com/RickMcConney/PenPlotter. To achieve smooth movement, a servo will be used to move the base with pens up and down. The other servo rotates the piece that holds the pens in place. It must be activated three times to rotate 90 degrees the pen holder. A stop piece locks the system so the pen holder stays in its correct position. Springs or elastic bands are needed to hold the stop piece and the moving arm against the pen holder.
