The Polargraph factory (my living room) is in full swing today. I had a bit of downtime when my 3d printer decided to start acting the goat, but I stripped down the heated print bed and rebuilt it, and it’s going gangbusters again. I’m printing in ABS. It doesn’t look that nice, but it’ll be better at taking the heat that these more powerful stepper drivers can pump into the motors.
I’m hoping to have this first handful of PolargraphSD kits on their way to their owners during next week, and at that point I’ll take a little stock to figure out how much they really cost all-in. The boards themselves are really cheap, but they use all SMT (surface mount) components and I know a lot of folk are wary of that – so will probably offer an assembled shield as part of an upgraded vitamins kit. I’m getting the hang of it. Don’t know what all the fuss was about!
Also, doing lots of drawings. These micro-stepping step-stick drivers are wonderfully civilised, so quiet and gentle. I miss the L293D’s singing a little though.
