As the holder for my spindle could be removed so that I could replace it with a laser module holder, or a pen holder, I sometimes found that this arrangement could very often cause inaccuracy issues. This was because the […] ↓ 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…
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…
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…
Some updates on the Movable Gantry CNC Machine: At the bed board frame, I found that the holes that I drilled for putting in the X-axis round rods were not positioned as accurately as I had wanted. The rods was […] ↓ 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…
Currently, what I did to obtain a zero position for my z-axis was to manually command jog linuxCNC to lower the z-axis until the milling tool touched the work piece and then set this position as the zero home position. […] ↓ Read the rest of this entry…
The previous test was only a simulation, but it was very useful. It served to teach me what to do in order to generate G-codes for the machine. Well, Christmas was over, but I did managed to have some time […] ↓ 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…
