Could someone measure the distance the first mirror is from their laser tube,

Could someone measure the distance the first mirror is from their laser tube, maybe with a picture so I know what corner your measuring to. I have a bunch of epoxy of the back on the back of my tube to seal a crack in the water section and it moved my tube forward a bit and I’d like to figure out where to redrill the mirror mounts. I have an idea with how I have it calibrated but wanted to start from the stock spot and I’m offset now.

@Eric_Rihm so annoying that you can’t post a pict. I re-posted it in the forum from my Photos alblum.

You can post an image url link where it’s hosted. Thanks

Can you get to this?: https://photos.google.com/share/AF1QipOaqtfbza1mB2dOH946pslAJ4YCK_diynGqzDDlaisK-NJ09LdYhXyipYhi3cfFbA?key=TE9BUDVySWtnSFJvdm1TZlo4Z3NhQ3VjZVA1V2t3

Yup! Exactly what I needed, much appreciated for the help.

Honestly that shouldn’t matter as long you can center the beam and send it back on to the other mirrors while keeping it centered.
