There really wasn't a need to do a video but I wanted to and that's about all the reason I need to shoot videos.

The upgrade is to place spacers between the frame and the rack on the Y axis so that the pinion will achieve 100% engagement on the rack. As designed, the pinion had about 75% engagement on the rack because the rack is bolted directly to the frame and that means you can't utilize all of the rack or the pinion would hit the frame (better explained in the video).

Several of us Saturn owners pointed this out to Nate and we discussed options for improvement. What Nate came up with is spacers that simply drop into place. I haven't had time to shut the CNC down but Friday afternoon all was quiet, no orders pending, and I figured this was as good a time as any. Good thing, too, because I got some Etsy orders today! Great!

Anyway, here's the video on installing the spacers -
