I’ve been busy getting the CNC Router assembled, aligned, powered, and controlled via software.  After MUCH learning, I was able to have my first trial run today!

Using CNC code that produces a 2D ‘sketch’ of the RoadRunner, the Router was run through its paces.  I ran the first couple runs ‘dry’, that is, the router bit wasn’t spinning and I just made sure the trajectory seemed correct.  Good thing, too, as I had a few loose items become ‘looser’ as the machine literally ground its way around the pattern.  But I was able to tighten things up, and, while still ‘temporary’ and needing some tuning, overall I was impressed with the results.  They were promising enough that I think I’ll try some 3D models next before I buckle down and fine tune the unit!

There was a lot of machining and alignment today.  As a result, I now have the X Axis pretty much ready to be tested.  The lead screws, pulleys, timing belt, and motor are in place.  Now all I need is the Stepper Motor driver to run the motor.  The driver is quite literally on a slow boat from China…  sigh…

Y Gantry riding on top of the X Axis. The X Axis has the two lead screws, pulleys, timing belt, and motor installed.

Today I was able to mount the Y Gantry onto the X Axis tracks and align the tracking bearings.  Happily, the gantry rolls very smoothly, without drag or observable play.

Yesterday was busy, cutting pipes, etc, but not much to show for it.  Today, at least, there is some observable progress with the X Axis tracks and frame in position…
