We have a new NL2500 with sub spindle and its the only Mori in the shop so all this is new to me...I am understanding the conversational programming a little more everyday but seem to have the most trouble with the milling process.
I am trying to mill a square with a X axis or O.D. live tooling holder using Y axis.
The material is 2 inch dia. and the square is 1.375 and it is from Z.0 to -Z 2.687 using a .75 endmill.I end up cutting in from z zero .150 and leaving stock on end and when looking at the simulation it is not going to full 2.687 location.
I also need to put a .687 radius on the end of the 1.375 square at Z.0 using the side of the end mill.
I am sure this is done easily thru capps, but when all you have is the Capps manual it is not all that clear and there is a lot of trial and era....mostly era!
Thanks for any help

Its a bit tricky to explain in 'CAPS terms' because there are so many different versions and menu changes between revisions and there are multiple menus to go through. It would be tedious to type up every single step on every single screen and every single menu option.
The only thing I can suggest is keep playing with it and read read read the manuals.

Most of the milling I do is simple so I usually program milling manually unless it's something really complicated.

A square on the diameter is very simple.

If I understand your description of the part correctly and you want to take it in one pass using 0.75" cutter (not using diameter compensation) something like this should do it using simple up and down passes in Y axis.

Also bear in mind NL2500 has +-2.0" Y axis travel so check the clearance as you approach the material

if you want to take a finish pass, copy it again and make the roughing passes come in to X1.4 then run it to size X1.375 on the 2nd pass.

note the Z is -2.312 because we're using center-line tool paths not diameter compensation. So 2.312" + half of the cutter diameter (0.375") equals a milled length of 2.687".
Maybe your program is similar and only going to Z-2.312? If yes that's why.

If this doesn't get you going, paste your generated program here and maybe we can see what is going wrong.
