Tell us about yourself!
I revisited it again this morning and I needed to do was take the two files into the Extensions directory. I'm more used to 3D printers, so got a bit confused until I realised the motors needed to be connected the reverse of each other! just need to make the pen carriage drop when the servo drops, so maybe a bit more weight on the carriage as I dont want to make the holes too large...But it's moving :-)
The plugin that you hacked seems only to be Windows based. Is there instructions for OSX (if possible)? I've built the machine, just can't wait to see it do something!
