ACRO 1010 with custom Z axis

The ACRO frame is unmodified from the stock 1010 kit that can be purchased in the Openbuilds part store.
My custom Z-axis will be the main focus of the build as it was inspired by and adapted from one of the designs in Mark Carew's Sketchup file that is attached to the Openbuilds NEMA 17 leadscrew linear actuator build page, but has been modified for my purposes.

I got the final part in and installed. I did some testing and have done a couple of small projects. Having the z-axis makes getting the focus correct much easier for me. I still need to try having it step in between passes when cutting to see how much difference it will make.

I'm going to mark the build as complete, but if you are like me, a build is never truly complete...

I like pictures, and not so much words... If you have any questions feel free to ask...


I started with a 500mm 2040 v-slot rail, and cut it approximately in half.


I mounted one half at the height I wanted and took measurements to get the final length I wanted for both of the pieces. My mounting piece is about 10" long and the sliding piece is about 6" long.


Getting all the parts ready for assembly. I purchased the shortest lead screw in the openbuilds parts store, and cut it down to about 6.5 inches for this build.


At first I tried to mount the v-slot directly to the ACRO x carriage plate, but I ended up running into clearance issues.



To fix the clearance issues I repurposed the acrylic spacers that go between the 2 plates for the original height adjustment setup. The 6mm thickness provided by the acrylic was more than adequate to eliminate any issues.



I have it on the table, and almost ready to go, but I'm waiting for another motor wire adapter to be delivered. Hopefully it will be here tomorrow.
