Hi Paul,

bit out of the way for me to come have a look but I have the same machine as you, I think. Did my alignments recently again too to make sure it was good. What seem to be the issues that you are actually having? Is the spot on each mirror not central? do you have differing intensity/focus with travel?

I find that if I am not getting good results it is usually warped wood being cut or dirty lenses. May not be your case but do give the optics a clean.

so let us know what happens and I will try and help you.
