For the movable gantry cnc machine, it was rather easy to notice and to adjust the X and Y axes so that they become perpendicular to each other. The movements of the tool would be rather large and would be […] ↓ Read the rest of this entry…
My Movable Gantry CNC Machine has already had T-nuts in place at the baseboard. What the machine needed now were holding down clamps. With the holding down clamps, I would be able to machine thicker objects instead of using double […] ↓ Read the rest of this entry…
When I am cutting materials by hand for my projects, a lot depended on whether I can mark out the designs accurately, particularly the right angles. I have a cheap engineer’s square (L-square) which I used for my projects, which […] ↓ Read the rest of this entry…
I had been experiencing several incidents of lost steps in the movable gantry cnc machine and I had been going through all the root cause analyses to find out the cause(s). Apparently, there were a few causes for these and […] ↓ Read the rest of this entry…
The timing belt mechanism for the Y-axis drive was constructed in such a way that there was a loop over an idler roller to ensure maximum engagement of the teeth of the stepper motor pulley with the belt. This arrangement […] ↓ Read the rest of this entry…
As I was planning to move the movable gantry cnc machine to my house in Butterworth, I had to consider how to fit it in place at the new location. The movable gantry cnc machine had to be placed at […] ↓ Read the rest of this entry…
One day, I was surprised when my computer did not give any response when I pressed the start button. Only a few days back, I had been using it, and it did not show any problem at all. As always, […] ↓ Read the rest of this entry…
Previously, I had to keep the computer, video monitor, keyboard, and mouse in a separate trolley on wheels so that they could be brought near to the movable gantry cnc machine when connecting to the breakout board of the stepper […] ↓ 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…
When I was building the moving gantry cnc machine, I was concentrating more on the machine itself, thinking about how to secure all the parts together to make a strong structure. Actually I realized that almost all the diy cnc […] ↓ Read the rest of this entry…
