Hi @ShawnBoyle , tysm for your reply.

I’ve vacuumed and blew out the lasers with special attention towards the collinear holes but the discrepancy between lasers still persists. I’ve taken my sensor down temporarily while i’m troubleshooting and will likely pursue sourcing a replacement sensor. I’ll shoot you a dm to discuss what my next options are. Thanks again!
