Ok, that was great. I clearly missed a few things here when setting up my RF45 (2018 almost new). Locking up the head does cause quite a few thou deflection so I see why it's important. I was lucky enough to talk to Stephan Gotswinter a few months ago on a youTube live thing he had going on. He's got an RF45 as well and we discussed rigidity issues with the mill.

Exactly what I was looking for, thank you!

Thank you!

What's the best way to secure the machinists square to the table when checking these things?
