IS M201 or M204 valid in klipper? https://reprap.org/wiki/G-code#M201:_Firmware_dependent ? https://www.klipper3d.org/Config_Reference.html https://www.youtube.com/watch?v=RgTvi0QqXho "max_velocity:

1. Maximum velocity (in mm/s) of the toolhead (relative to the
2. print). This value may be changed at runtime using the
3. SET_VELOCITY_LIMIT command. This parameter must be specified.

max_accel:

1. Maximum acceleration (in mm/s^2) of the toolhead (relative to the
2. print). Although this parameter is described as a "maximum"
3. acceleration, in practice most moves that accelerate or decelerate
4. will do so at the rate specified here. The value specified here
5. may be changed at runtime using the SET_VELOCITY_LIMIT command.
6. This parameter must be specified.
7. minimum_cruise_ratio: 0.5
8. Most moves will accelerate to a cruising speed, travel at that
9. cruising speed, and then decelerate. However, some moves that
10. travel a short distance could nominally accelerate and then
11. immediately decelerate. This option reduces the top speed of these
12. moves to ensure there is always a minimum distance traveled at a
13. cruising speed. That is, it enforces a minimum distance traveled
14. at cruising speed relative to the total distance traveled. It is
15. intended to reduce the top speed of short zigzag moves (and thus
16. reduce printer vibration from these moves). For example, a
17. minimum_cruise_ratio of 0.5 would ensure that a standalone 1.5mm
18. move would have a minimum cruising distance of 0.75mm. Specify a
19. ratio of 0.0 to disable this feature (there would be no minimum
20. cruising distance enforced between acceleration and deceleration).
21. The value specified here may be changed at runtime using the
22. SET_VELOCITY_LIMIT command. The default is 0.5.
23. square_corner_velocity: 5.0
24. The maximum velocity (in mm/s) that the toolhead may travel a 90
25. degree corner at. A non-zero value can reduce changes in extruder
26. flow rates by enabling instantaneous velocity changes of the
27. toolhead during cornering. This value configures the internal
28. centripetal velocity cornering algorithm; corners with angles
29. larger than 90 degrees will have a higher cornering velocity while
30. corners with angles less than 90 degrees will have a lower
31. cornering velocity. If this is set to zero then the toolhead will
32. decelerate to zero at each corner. The value specified here may be
33. changed at runtime using the SET_VELOCITY_LIMIT command. The
34. default is 5mm/s.
35. max_accel_to_decel:
36. This parameter is deprecated and should no longer be used."

"rotation_distance:

1. Distance (in mm) that the axis travels with one full rotation of
2. the stepper motor (or final gear if gear_ratio is specified).
3. This parameter must be provided.

microsteps:

1. The number of microsteps the stepper motor driver uses. This
2. parameter must be provided.
3. full_steps_per_rotation: 200
4. The number of full steps for one rotation of the stepper motor.
5. Set this to 200 for a 1.8 degree stepper motor or set to 400 for a
6. 0.9 degree motor. The default is 200.
7. gear_ratio:
8. The gear ratio if the stepper motor is connected to the axis via a
9. gearbox. For example, one may specify "5:1" if a 5 to 1 gearbox is
10. in use. If the axis has multiple gearboxes one may specify a comma
11. separated list of gear ratios (for example, "57:11, 2:1"). If a
12. gear_ratio is specified then rotation_distance specifies the
13. distance the axis travels for one full rotation of the final gear.
14. The default is to not use a gear ratio.

" 2025-06-9 The printer.cfg max acceleration is 3000mm/s**2 I changed the max accelleration in the gcode with M204 S100 right before the skirt. this was inserted using the Prusa Slicer. While Marlin allows separate acceleration values for X,Y,Z and E Klipper is more limited.
