Re: Mirror alignment - how often?

forgot to mention, we have several machines, but the best for mirror alignment is Thunderlaser, I have a several Thunderlasers, some I have never had to adjust the mirrors and they have been used over 3 years, yet the rabbit machine we had to adjust daily ( until I fitted lock nuts )
