Taking note of the findings after rough tramming of Z-axis on the Movable Gantry CNC Machine, I decided that the Movable Gantry Z-axis drive mechanism needed a major makeover as there were too many inaccuracies. These inaccuracies came about because […] ↓ Read the rest of this entry…
Recently, I came across some techniques for stippling pictures which were suitable for cnc milling. The strippling technique was ideal for the pen plotter, but since I had already installed a milling spindle for cutting, I thought it would be […] ↓ 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…
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…
While I was looking at the assembly of the CNC machine from afar, I found that the left side wall was not exactly perpendicular to the movable bed. It was noticeable because the wall was relatively tall, and when viewed […] ↓ Read the rest of this entry…
