I ran a bunch of tools on our marposs toolsetter last night.
Length measuring is coming out to be +/-.0001
When having it measure the diameter of a tool I am getting +/-.020+
I'm taking some gauge pins home this evening to re-calibrate it but wanted to ask if there were any settings I should check??
Although my laser is on an okuma vmc, I am having the same issue you are; no one seems to know anything about them. I have yet to be able to find any osp programs/subprograms that will check tool diameter. I keep getting told that "no one uses the laser to check diameter", which blows my mind. I would love to get my hands on information about programming the damn thing, all I have been able to find is an installation manual.
Have you inspected the laser to make sure its tightened down to the table? The air pressure from the laser blower could be shifting it when it checks the cutters.
Also, is it possible that your tool holders or spindle chuck cavity has wear or damage and is giving you runout?
Lastly, have you tried hand indicating the cutters when they're in the spindle to check run-out and diameter. For fussy jobs, I usually indicate every tool in the spindle rite off the bat. I rarely have been over .0004.

well sence its still going,
make sure the pad is tight and square, then do all your calibration.
those pads come loose every once in a while. use a heigth gage and get it within .0001 flatness.
is it giving you diameter errors when you check the tool that you use for the calibration program?
If so have you tried checking the reference tool for any type of run out? It is possible that that tool got bumped and is off, there-for screwing up your calibration, furthermore screwing up everything afterwords.
Its a long shot but an easy fix if that's whats going on.
You could also try indicating the laser itself to make sure its still square and hasn't been moved at all. If it was bumped at all then it wont be lined up with the work offset in the calibration and gauging programs.
Seems to be some confusion here whether it's a laser type or probe type. Laser types can have issues with tool diameter for sure.
