I have been able to align my Beseler 45MX enlarger side-to-side and front-to-back with respect to the baseboard per the instruction manual, but I still have some un-uniformity in focus. I haven't been able to find any adjustment screws or instructions on how to adjust the lens board and negative carrier so they are absolutely parallel side-to-side and front-to-back. Any ideas.
It has been a while since I worked on one, but try this. On the underside of the lens stage is a nut just behind where your lens is while looking from the front. Take your lens off if you haven't already. Loosen that slightly and you should be able to rotate the lens stage independent of the neg stage. If you have fore and aft sag on your lens stage and or your upper housing it is a bit harder to figure out. There are nylon bushings that slide along the track that can sometimes wear out, there are small screws on each one that can be used to loosen or tighten the grip on the track, if you have play there it will let the enlarger head and or the lens stage sag. It has been a few decades since I did these procedures but this should give you place to start, hope this helped.

The nut on the lens stage will allow only swivel left/right, if you will. No easy adjustment for fore/aft.
Shim it.
The MX series is a huge downgrade from the older and more adjustable CB7. Everything about the CB7 is better, including larger condensers or diffusion plate.
CB7 also has adjustable speed power focus and shared the power elevation with MX.
The one advantage to MX is it's horizontal tilt capacity for murals.

The CB 7 came out well after the MX was available.Originally Posted by Randy Moe
Good to know, but mine are so old I can't find info on an Agfa color head.
Maybe the difference is commercial vs hobbyist?

This is what I use to align the lens: https://www.bhphotovideo.com/c/produ...able_Lens.html It's no longer available but you may still be able to find it or make one yourself.

No, different design team. I was the Product Manager for both of them.
Regardless of age, I prefer CB7.
Some parts interchange elevation motors, drive belts, lens boards, negative carriers, but heads do not
The Adjust-A-Tables are differently sized, yet identical in design. A really good design as it knocks down for shipping and the MX can be setup to enlarge to the lower shelf.
There was a website with detailed info & pics of MX, CB7 but it's gone....
The CB7 had to be way more expensive.

So, Bob, is there a way to align the lens board and negative carrier? Oh, and it is a 45MXT?
