Update: Left side support file added.

I don't have fusion 360 install, does anyone has a solidwork file of this side support?

My 9mm belt and pulley arrive I am excited to do all the upgrades starting next week.

thanks

Attached are both left and right side supports in STEP format. Hope that helps.

Be sure to check dimensions against your machine before milling as these dimensions were taken from the SO3 model on the wiki.

Finally finished with FIRST Robotics season and had a chance to finish my write up on the spindle carriage plate stiffeners: http://engineerinback.com/shapeoko3-z-a ... stiffeners

My STEP files are also hosted there if anyone is interested.

Got a ton of use out of the machine during the FIRST Robotics season The stiffened carriage plate really helped speed up the 1/4 inch thick parts. The kids were pumped that they could design something on a Friday and I could come in Saturday with a finished part:

Great post, what is the approx rpm did you use on your set up?

I'm running the Dewalt at a '5.5' on the dial.

A super PID is in my future...but I wanted to get the things that would show the biggest improvements out of the way first.

Neppo, when you drill the steel Z plate do you also tap it ? or you just tap the aluminum support ?

The holes in the steel Z plate are clearance size for the hardware I used and are not tapped. Only the holes in the aluminum stiffeners are tapped.

I was running into issues with the z plate stiffness and decided to make a couple stiffeners..

Not nearly as pretty as several of the ones done here, but as much as I wanted to machine them I ended up just using some 1/4" aluminum angle I already had on hand.

I cut one leg down to half an inch and drilled and tapped it for 1/4x20 screws

After drilling and countersinking the z plate i assembled everything and then added the 2 1/4x20 bolts into the spindle mount.

It made a huge difference... Well worth it.

I am slowly and painfully doing the z axis plate upgrade and fixing all the wheel shim as well . I think it's going be worth it at the end.
