I understand that the X should be the shorter length vs there Y. I used to have another CNC and the X was about 50" long and Y was about 36". I want a cutting area about 22" deep vs 40" wide. Can V4 be configured that way or do I need to make the Y 40" long and the X 22 wide? If that’s the case, where is home on the machine located?
The X is the weaker of the two, so it is in your best interest to make it the sorter one.
So where is the home located? If the x and y form an L tipped to the right, is the home the bottom of the short length? Does that make sense.
The LR will home to the front left corner, with the Z at the max.
Machine coordinates are fairly universal, X is left right, Y is away from you, Z is up and down. Left close and down are machine minimums.

The way I need to orient the table the X will be N/S and Y with be E/W.
The link has a picture of home on a LR. The way you put your table in your shop dictates where that is.
Beyond that your CAM is how the project is oriented on the table. There really should be no issues with changing which direction the rectangle is longer.

Thank you. I guess I will need to build one (probably in April when it’s warmer) abs play with the machine. I used to use Vcarve Pro but might try something else. Or maybe start with Desktop and see how it lines up. I appreciate the responses.

You may already know, but keep in mind that Vcarve Desktop is limited to 24"x24".
Yes I am aware. I can always tile a project if I go larger.
As noted above, X in the standard build configuration should be the shorter axis. The reason for that is to make the gantry as short as possible, for maximum stability and rigidity.
It Is possible to re-arrange the motor wiring (and also the controller configuration, if using the SKR Pro V1.2) to make the gantry the Y axis. This still keeps the gantry as short as possible, but also uses a “Landscape” rather than a "Portrait) orientation, which may be what you are thinking about. The details differ slightly depending on the controller. Also the LR4 does have additional endstop screw holes to allow you to alter the homing locations when using portrait orientation.
As mentioned in many other threads, it is strongly advisable to build your machine as a standard build first, and then make any desired mods after you have climbed the learning curve and have worked out all of the bugs. This makes it much easier for you to get it up and running properly, and makes it much easier for the other forum members to support you and your standard build.
If you do decide to make mods after you get your standard build running, please remember to include a fairly detailed description of the mods in any future support threads,. Failure to do so may confuse new readers looking for support on standard builds, and answers from other users may refer to a standard build, rather than being applicable to your modified version,
