All these while, I had been operating my diy movable gantry cnc machine as a milling machine. I knew that I could easily convert it to become a laser cnc machine, but somehow I had kept postponing it. Perhaps I […] ↓ Read the rest of this entry…
I had obtained a few pieces of phenolic boards that was discarded from a switchboard maker. As they were quite stiff I thought I could make use of them to make some clamps for my movable gantry cnc machine. I […] ↓ Read the rest of this entry…
Today, we look back at how we have progressed with our cnc machines. I started to investigate how to control cnc movement using a floppy drive. The floppy drive of a computer already had a stepper motor for moving the […] ↓ Read the rest of this entry…
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…
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…
I had been experiencing several incidents of lost steps in the movable gantry cnc machine and I had been going through all the root cause analyses to find out the cause(s). Apparently, there were a few causes for these and […] ↓ Read the rest of this entry…
One day, I was surprised when my computer did not give any response when I pressed the start button. Only a few days back, I had been using it, and it did not show any problem at all. As always, […] ↓ Read the rest of this entry…
Because I used LinuxCNC for operating my cnc machines, I was always interested in getting computers that were built with parallel ports. Normally this would mean that the computers were quite old and could be quite slow by present day […] ↓ 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…
