Jann, Thanks for posting pictures. Was there any code or electronics changes needed for the optical switches?

Jann, More pictures would be great. Thanks! Have you seen improvement in performance with the optical limit switches?

Great job! Can you provide more detail on the optical switches used and what parts you needed to change?

Thanks for posting your build progress. Really impressive! I would be curious to see how you end up storing in a case when you have that done.

Nhan, I am still sourcing electrical items including wiring. Any update on your results? Jeff

John, I am working on control box layout for a new AR4. I would be interested in seeing completed photos of your build! Jeff

Thanks for posting the enclosure CAD file. Stepper Online has the stepper driver CAD files under the Download tab.

Mateo, I have started sourcing parts for a new AR4 build and I have not decided on the enclosrue. I would be interested in the CAD files if they are available online. Great job on your build by the way! Jeff
