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…
The timing belt mechanism for the Y-axis drive was constructed in such a way that there was a loop over an idler roller to ensure maximum engagement of the teeth of the stepper motor pulley with the belt. This arrangement […] ↓ Read the rest of this entry…
As I was planning to move the movable gantry cnc machine to my house in Butterworth, I had to consider how to fit it in place at the new location. The movable gantry cnc machine had to be placed at […] ↓ 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…
Previously, I had to keep the computer, video monitor, keyboard, and mouse in a separate trolley on wheels so that they could be brought near to the movable gantry cnc machine when connecting to the breakout board of the stepper […] ↓ 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…
When I was building the moving gantry cnc machine, I was concentrating more on the machine itself, thinking about how to secure all the parts together to make a strong structure. Actually I realized that almost all the diy cnc […] ↓ Read the rest of this entry…
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…
