Opticals are logic devices, so you'd possibly need to add couple logic gates to avoid them interfering with each other. Best to direct that question at your sensor's 3rd party vendor for them to provide details on their product. Maybe maybe not. Or keep it easy and just go with docs:blackbox-x32:connect-xtension-limit [OpenBuilds Documentation] Autosquare: Rather just tram the machine? Tramming: A generic guideline - autosquare maybe has a use case for flimsy belted machines, everything else just build it square instead of using motors to pull an out of square machine into "fake square" forcing the linear components, causing unneccesary wear and tear. If you are constantly going out of square, something is wrong. Fix that instead
