The Y axis for the movable gantry cnc machine was originally designed to be driven by GT2 timing belt. However, the results obtained after undergoing detailed 2.5D scanning parallel cuts showed that the tool tended to lag when it encountered […] ↓ 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…
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…
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…
Since the testing of the 3 axis stepper motors interface with the computer program was successful, my next task from now on will be to fabricate the mechanical parts of the cnc machine. The dot matrix printer ink carriage […] ↓ Read the rest of this entry…
