Last weekend was the first time I got my cnc router to do something recognisable. After some tuning I got it to plot out a simplified version of my blog logo, backwards…
I was having some difficulty understanding what was going wrong with my circuit. This week i got some probes for my oscilloscope, and that at least helped me see that indeed when the servo turned the best, the control signal looked most like a square wave
I ordered some new bolts with allen key heads, and some nylon insert nuts. The idea being that I’d get more torque on my tightening, higher locking force and better resistance to coming loose.
For some time I’ve toyed with the idea of building my own cnc router, or perhaps a 3d printer. The idea, of having a tool which allows me to fabricate parts using a computer to control the process, is pretty compelling.
