We do the same thing as 190. Our machine only has 20" of X travel, so when we cut our frame rails we cut the left-most bearing housing pocket, the center bearing housing pocket, and all the gearbox mounting/access holes. We then slide the part all the way to the left, so that everything to the right of the center bearing housing pocket is inside the x-travel envelope. We probe off of the bore (since we have the part probe), but if you were to make this same part, you know the distance to offset your tool from the top face of the 1x2 to the center of the bearing bore and you can go to that distance, then just use an edge finger to find the left or right side of the bore. You can then offset the correct amount to find the center. This becomes even easier if you have a square/rectangular feature you want to locate off of.

Haas has a lot of good documentation here. I would suggest downloading and completing the Mill workbook. When I was taking CNC classes we used it and it was very beneficial to learn the formatting of various g-codes.

Will you be using a CAM program or writing G-code manually?

Best advice I can give-don't get ahead of yourself at first. You may think you've got something down pat and get over comfortable. That's when you break things (badly). Always have a second pair of eyes look over any code you intend to run for the first time, just to be sure (that, and single block with the rapid override on 5% whenever you run a program for the first time).

If you have any questions, feel free to contact me.
