Well done mate. Nothing like seeing the fruits of your labour come to life. I love the use of a bearing as a weight. You need to add a smiley face to it or some googley eyes just for laughs.
Yes, the pen currently doesn't lift from the page. I have the capability to move a servo to lift the pen, but the pen holder (gondler) needs a redesign.
Biggest challenge for me was to create good line drawings. Spend hundreds of hours writing software for that. Oh man... Been a long time since I've worked on that project. One day I'm gonna share 🙃
Yes, doesn't do straight lines well especially if they are long one. The trick I've found is you need to break each long line into shorter segments and then it comes out much better. But this is not the setup for perfection, a lot of hysteresis in the system.
