Now that all the major modifications had been made to the movable gantry cnc machine, the final part was to calibrate and tram the z-axis again. As a recall, the work being done as major modifications were: The z-axis housing […] ↓ Read the rest of this entry…

Because I used LinuxCNC for operating my cnc machines, I was always interested in getting computers that were built with parallel ports. Normally this would mean that the computers were quite old and could be quite slow by present day […] ↓ Read the rest of this entry…
I have decided to use the same Z-axis design for both the movable bed cnc machine and the upcoming moving gantry cnc machine. In this way, I do not have to buy another spindle for the new machine, but can […] ↓ Read the rest of this entry…
Previously, I had tried to increase the speeds of the CNC machine with disastrous results. The reason was that the stepper motors which drove the movements in the axes would stall if they encountered more load than they could take. […] ↓ Read the rest of this entry…
I had been using my movable bed cnc machine to fabricate parts for my other projects. For example, I had machined out a pocket from a piece of wood for use as a sliding block for my drill bench press. […] ↓ Read the rest of this entry…
I always wanted to do something with my old CD’s. I must admit that I have a certain fascination for CD’s because the close lines on the surface causes interference of light which then breaks up into rainbow colours. By […] ↓ Read the rest of this entry…
With all the testing successful, it’s time to consolidate and improve on the overall machine. What I wanted to do was wire management. My wires had been dangling around, and were made up of all sorts of wires. In order […] ↓ Read the rest of this entry…
After testing the movement of the X-axis successfully, my next task was to fabricate the other axes, namely the Y and Z axes. The Y-axis was not much of a problem as it followed very much the same design as […] ↓ Read the rest of this entry…
At this juncture, I had to consolidate what I had available and decide what kind of design of the cnc machine I wanted to build. Most of the decisions that I made were based on the parts that were available […] ↓ Read the rest of this entry…
