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…
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…
I always wanted to do something with my old CD’s. I must admit that I have a certain fascination for CD’s because the close lines on the surface causes interference of light which then breaks up into rainbow colours. By […] ↓ 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…
Chinese New Year 2016 holidays had already come and gone. I was hoping to complete the CNC machine before that, but was delayed due to other pressing matters. While waiting for the milling spindle to arrive, I tried out some […] ↓ Read the rest of this entry…
During my experimentation, I somehow made costly mistake(s) and found that the parallel port installed at my computer was not working properly after one initial successful testing. Subsequent testing were failures. I did not know why and when it occurred. […] ↓ Read the rest of this entry…
