@SnowDrifter What is the purpose of this thread? Are you asking a question, making a statement, asking for advice, or requesting a change or additional feature?
Ultimately, the maximum motor speed will be determined by the torque curve of the motor(s). The maximum acceleration is a function of that torque divided by the mass to be moved and the maximum speed can therefore be calculated as sqrt(2x acceleration x distance/2). Most machines will never attain the maximum motor speed unless the axes travel distances are large enough to accommodate the acceleration and deceleration phases. In general terms, it is the rate of acceleration that the machine can withstand which will determine the maximum speed that can be attained. But that only applies to non-print moves. Print moves will be limited by the speed at which filament can be melted and extruded and those moves will be far below the motor speed limits.
It's a feature request. I want to limit individual motor speeds as the traditional X and Y speeds don't apply well to a corxy since everything's 'rotated' 45 degrees.
