Various ramblings – Electronics, Radio, 3D Printing & CNC
A few pictures of a test run trying out isolation PCB routing. GCode was generated using the PCB-Gcode script for Eagle, using the backplane board from my 6502 project as input. Part way through the run I noticed that the mill was slightly out of alignment on the X-axis, this was causing shallow track cuts which got progressively worse the further...
Some pictures of the finished mill and the first cuts of my own design. Prior to this I had done some test cuts using the default “LinuxCNC” logo, the very first cut was actually flipped on the Y-axis… Configuration fail!
Another one of those cool “toys” I thought I would never be able to afford but lusted after all the same. With the availability of cheap stepper motors, driver circuits and free software (LinuxCNC), CNC mills are starting to become quiet affordable for home use. Of course there are limitations. Just like my lathe this mill is only a baby,...
While working on a small PIC project as an addition to a larger project (a JUMA RX1 DDS LSB/CW receiver) I had the displeasure of using Microchip’s IDE MPLAB. MPLAB looks like it was designed in the mid-90’s, and while it does let you piece together code and compile it into PIC compatible hex, it’s not the most user friendly...
