Having started printing parts for this cam-driven drawing machine I shall soon find out if an uncomfortable amount of trignonometry has been done correctly or not

#3dprinting #openScad

Screenshot of a Linux Mint desktop showing the application OpenSCAD. In the window the left hand pane has fragments of OpenSCAD language. In the right hand upper pane there is a multicoloured preview of a structure with a big blue cam with an irregular outline, just visible underneath a smaller red cam is just visible. The main structure is yellow with one pink part and looks like a pantograph with a parallelogram structure. Parts of the structure are pressed against the cams so as to drive its movement.

(If you would like the code it will be shared in full at some point once I know if it will work or not)
