The movable gantry cnc machine would be driven by timing belts because I did not have lead screws that were long enough to cover the lengths of travel of the x and y axes. Compared to the movable bed cnc […] ↓ 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…
In the previous post, I had managed to cut the gantry bottom plate reasonably square and accurately. That was a great help in the alignment of the two gantry sides. Using the same exact measurement as the distance between the […] ↓ 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…
My last post was about preparing the graphic photograph image of my son and converting it to g-code and then machining it on my movable bed CNC machine. That was when I found that the movable bed of my CNC […] ↓ 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…
