Custom size 450x500
Would ratrig OS work of I built a rectangular size printer? 450x500 covers what I'd need and I could make the gantry a little lighter. I just don't know if the software for bed leveling and such would need tweaking or if it's even doable?

You'd only need to override
[stepper_x] position_max, the max points of [bed_mesh] and the last z_positions and points on [z_tilt] to make that work.
basically just copy those parameters from 500.cfg and subtract 50 from the max X values.Awesome, so the rectangular plate wouldn't affect the bed leveling geometry if the values are changed?
Fun fact about the kinematic coupling. It works regardless of bed shape. The intersection point just needs to be somewhere inside the bed area. The closer to 45 degrees the more rigid the mount is. But unless it's literally 0 (ie, the two arms at the front point at eachother, for example), it will do it's job, it just changes the "transform origin" 🙂
If that's what you're referring to by "bed leveling geometry".
The points probed are adjusted via
[bed_mesh] and [z_tilt] like i mentioned earlier.Great! Last questions is there a specific reason the tooling plate is 29mm larger than the bed?
Would rotating the gantry 90deg so that it moves left to right instead of front to back affect the software?

Would rotating the gantry 90deg so that it moves left to right instead of front to back affect the software?That would require a complete redesign of the X/Y gantry, and whether it affects the software depends on that redesign.
