License key that supposedly should unlock the USB controller hardware. The included software was obviously a copy ofĬommercial software from PlanetCNC and included a handwritten Shipping time (it landed on my desk in only a few days) and best of all no hidden extraĬosts like import duties and other taxes. Individual had already imported those CNC mills into Germany. I could order my CNC 3040 from the German Amazon webshop. In the data stream with an imperfect piece as a result. (over 100 kHz) and not much is needed in a non realtime OS like Windows to get a hickup The CNC software isĬontrolling the data pins of such a parallel printer port directly at very high speed With a parallel printer port which is the other very popular way of driving a CNC millīut, of which I have big doubts if this can work 100% all the time. With ball screws which should be more precise.įor the controller, I opted for a USB capable one since I have no old PC’s around anymore There are quite a few versions of the CNC 3040. More than big enough for my needs (I thought). That CNC mill offers a working area, as you canĮxpect, of roughly 30 by 40 cm. Interesting (no more chemicals) and researching a bit more I decided to invest in one of Then I found some videos of people making their PCB’s with a CNC mill. That looked promising but this would still involve chemicals that I’d prefer not to use One interesting one was using the laserĪnd rotating mirror of a laser printer to draw the PCB design on a photo sensitive PCB. LookingĪround, I found some other ways to make PCB’s. Once that was done, etch the PCB with ferro-chloride.īoth ways of working involve, not so innocent, chemicals that I’d like to avoid. directly drawing the design on a blank copper PCB with tape and water resistent ink.Thenĭeveloping the PCB (just like a photograph) and etching it with ferro-chloride. The sun…) and photo sensitive PCB’s to transfer the design to the PCB. drawing/taping the pcb traces on transparant/chalk paper and then use a UV light (or.
Breadboards are nice for experimenting but at aĬertain time it would be nice to have something more permanent on a PCB to build in a Once I decided to pick up my electronics hobby again (around 2017) I had to think on how A bit of history - A small series about my CNC adventure.
