CNC – First 2.5D cutting

I have designed a bracket that I used as my first attempt to manufacture something with my CNC mill. Because I’m still using python code I wrote myself and have not yet calibrated my stepper coordinates into real-world measurements, I had to design the bracket in Inkscape, print it out, and manually move my router bit to each point to determine the stepper coordinates along the path I wanted to cut out. This really sucked, and I plan on switching over to the parallel port controller board and EMC2 very soon so that I do not have to keep writing code. (I had to add code to cut out the bracket that interpolates between two endpoints so that I could route semi-accurate 60 degree lines.)

The piece of wood was secured Continue reading
