So, lets say I have a machine that has non-tricial kinematics (I mill with the z-axis tilted 30 degrees) and I write the kinematics routines correctly. Then you are saying the machine will not honor accel and velocity limits?
But all machines are like this, not 30 degress certainly but some number of arcseconds. A nice feature would be to compensate for all the errors, not just the bed. I would not be surprised if non-trivial kinematics is broken as so few people have machines with not-square axis the code would not be well tested. That said, te velocity problem is proportional to the cosine of the tilt. It is going to be tiny.
