This is a CNC test video, I am using my DIY pen holder to draw a pattern and write. The pen holder is just another DIY project, it took me about an hour to make it, including the figuring out of "how to make it" and from which readily available material.

My DIY CNC is upgraded. The mechanical parts are replaced, I made a new X, Y and Z axis. The upgraded CNC has 16mm supported round rails and 1605 ball screws and ball nuts. The speed is increased by 3 times, maximum speed is now 1500 mm/min, using the same NEMA23 steppers and 24V driving voltage.

Next in turn for upgrade is the electrical parts, new power supply and control box will be made. I have all the parts and will start as soon as I fixed a dust extractor as well. After that the spindle will be changed as well, probably a water cooled brush less VFD motor will be the one.
