Is the pinion rubbing against the frame (last photo)? Ours is about 1/8" away from the frame. I think Nate is working on spacers to retrofit the first Saturn machines or deeper racks for the newer models but I'm not aware of a release date - thought it was in effect for the machines going out the door now, though.

Nate will have to comment on that, there is about 1/8" on one side and even less on the other, there does not feel like there is any play in the pinion or pulley system.

Good to hear that the drives seem solid. I'm looking forward to reading about the build!

David,

We swapped out the washer under the pinion for a split lock washer. That moved the pinion inward a bit. It's about 3/64 from the edge.

Nate,

So is that supposed to be our solution? Still seems like a wider rack would be be better...

The ideal solution would be to space the rack out with some flat stock like cncrouterparts does vs the spacing the pinion gear out more. It's basic engineering 101. The flat bar would have much more contact area than the washer behind the pinion gear.

This wouldn't be a fix to me.

Also, note that the split lock washer was not designed to move the pinion closer. It was designed to replace a flat washer to reduce the contact area of the washer to just the inner race. The flat washer extended out one the bearing cover and in some instances caused binding.

In this case, the split washer just happens to be thicker and moved the pinion inward slightly.

We are still planning on moving to a wider rack. We have 3/4in wide rack being manufactured, which should give you more contact area than just using a spacer.

Right now though, the current 1/2in wide racks function fine. I am also still planning on offering the spacer to those that want it. The spacers are in transit and should be available in about 2 weeks. We have sized the screws on the Saturn machines long enough that you should just be able to unscrew the screws part way, drop in the spacers, and tighten back up.

Looking forward to getting and installing the spacers. I'm not having any problems since I replaced the R&P drives, but improving the rack contact has been on my list of needed improvements. Thanks for the update.

I too would like the spacers when they become available. Thanks Nate.
