I had been quite successful doing single depth of cut engraving for some time now. Now I was looking for new capabilities. I had previously cut some 2.5D graphics on wood or phenolic boards. It was during one of these […] ↓ Read the rest of this entry…
As my movable bed cnc machine was quite small, the whole machine, computer CPU, monitor, keyboard, and power supply were able to be placed on a trolley. This made it easier to move the whole assembly around. This feature was […] ↓ Read the rest of this entry…
I had engraved many old CD’s with words and pictures with my cnc machines. Initially, I used to clamp the cd’s onto the waste board with the help of wooden clamps. I had to arrange the setup so as not […] ↓ Read the rest of this entry…
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…
The Y axis for the movable gantry cnc machine was originally designed to be driven by GT2 timing belt. However, the results obtained after undergoing detailed 2.5D scanning parallel cuts showed that the tool tended to lag when it encountered […] ↓ 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…
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…
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…
