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
The cam driven #openScad drawing machine seems mostly to work. It's also part of an announcement:
With other people around the area I live in I shall be exhibiting at the BS5 Art Trail on 7 & 8 September. I'll be in St Mark's Church in Easton & I'll have my H-Bot pen plotter and this one working - come along if you're interested in plotter art or if you want to see what art East Bristol is making :)
Next I probably need design a simpler pattern...
