Birth of a 4-axis CNC machine #12: X axis build (again)
I put off assembling the x axis rack and pinion until I was able to purchase the rest of the parts. The y and z axis has to build on the x axis. I bought the linear rails a long time ago, so the y and z were built on top of this. Well, now that I am ready to finish the x axis, I had to remove the y and z from the gantry. The pinion gear assembly took a bit of work but they are finally ready. Due to the depth of the pinion gear and the mounted flanged bearing, I had to build out the ends to get the correct spacing. I debated about banding the edges first or fitting everything then banding.When push comes to shove, I wasn’t certain I wouldn’t be remak...
