The Movable Gantry CNC Machine will have a much larger cutting area than my Movable Bed CNC Machine. So this would, in fact, give me more flexibility in terms of the jobs that I could handle. What I could think […] ↓ Read the rest of this entry…
The movable gantry cnc machine that I am making would have a bigger working area than my previously made movable bed cnc machine. Therefore, using a drag knife to cut thin pieces of cardboard, plastic sheet and similar materials had […] ↓ Read the rest of this entry…
In my previous blog post, I mentioned that I had done many activities in order to make the dual motor x-axis work using Polulu A4988 stepper motor drivers. I also mentioned that I kept burning up the drivers due to […] ↓ Read the rest of this entry…
I have decided to document some of the activities that had gone on since the last time I burnt my stepper motor drivers. It was interesting for me and maybe it could be interesting for some of you too. As […] ↓ Read the rest of this entry…
This year, I am going to engrave a birthday greeting for my daughter on a CD. At this moment, I am experimenting with engraving on CD and I am very keen on letting people become aware of the verses in […] ↓ Read the rest of this entry…
My project for Moving Gantry CNC Machine had hit a snag! Because the moving gantry cnc machine was driven by 2 stepper motors for the x-axis, my full attention was focused on how to connect them from LinuxCNC software configured […] ↓ Read the rest of this entry…
Halfway through making the y-axis drive, I realized that I had made a mistake in the placement of the belt idler bearings. At that time my focus was on placing it in such a position that there would still be […] ↓ Read the rest of this entry…
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…
