The next set of tweaks is done on the drawing, we’re going to try to get the new carriage assembly set up and cut out in the next couple weeks, and this time around – we’re planning to mount a Dremmel with a grinding burr as part of the test. (Prior to that I have to make up some blanks with paper taped on, and create a marker holder that can be mounted to test some of the pattern logic out. I’ve uploaded this plan to the 3D Warehouse for those that are interested.
