I had obtained a few pieces of phenolic boards that was discarded from a switchboard maker. As they were quite stiff I thought I could make use of them to make some clamps for my movable gantry cnc machine. I […] ↓ Read the rest of this entry…
This is a continuation of the improvement in the Z-axis for the movable gantry cnc machine. The previous post was about making a more accurate vertical z movement by changing the Z housing from one made of MDF to another […] ↓ Read the rest of this entry…
The movable gantry cnc machine that I am making would have a bigger working area than my previously made movable bed cnc machine. Therefore, using a drag knife to cut thin pieces of cardboard, plastic sheet and similar materials had […] ↓ 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 was now ready to explore what I can do with my new cnc machine. I happened to have a soft board lying around after I had cut some discs out of it for stopping my x-axis parallel rods from […] ↓ Read the rest of this entry…
After my first cut, I knew I had to fix a backing spoilboard on the machine movable bed so that I can protect the latter from being damaged when the tool cut deeper than the thickness of the work piece. […] ↓ Read the rest of this entry…
Chinese New Year 2016 holidays had already come and gone. I was hoping to complete the CNC machine before that, but was delayed due to other pressing matters. While waiting for the milling spindle to arrive, I tried out some […] ↓ 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…
