My default profile has bulging corners but almost no visible ringing, but I'm happy to run some tests for you with more aggressive settings. (Looking forward to the new motion planner!)

Can you give me a table of test values you'd like to see? For reference, I'm on a CoreXY with a default profile of 180 jerk, 3600 accel, 60mm/s external perimeters. With these values, I have no observable ringing on the X-axis, and (if I squint hard and use a flashlight) 0.6mm wavelength on the Y for an 0.01s period, assuming it was up to speed at that point.

On 2.0RC6, DWC 1.21.1, I'm seeing the same thing as @zerspaner_gerd . When filament is loaded, I can click "Tool 0" to get a dropdown and select "Unload Filament". Once that's processed and the filament is unloaded, the menu is gone. If I click "Tool 0" at that time, it just cycles Active/Standby/Off.

M701 S"..."from the gcode console works fine, and once the new filament is loaded the menu re-appears.

With the RTOS port I assume it's now easier to add additional background tasks to the firmware. When a print starts, could the firmware also start running a simulation in the background, and when complete that simulation time could be fed back to DWC/PanelDue for an additional (and presumably more accurate) print time estimate?
