6 months ago Restoration of M204 settings is now implemented in 3.5.0-rc.4. Restoration of jerk settings has not been done because it is not clear that it is a good idea. The original reason for jerk settings was to specify the limits that the machine is capable of. Unfortunately some slicers now generate commands to set jerk limits. One possibility is in future to treat M566 as setting machine limits (just as M201 sets machine acceleration limits) but treat M205 as setting possibly lower limits for the current print only (just as M204 sets travel and printing acceleration limits for the current print only).

What happened?
I am using Duet 2 wifi with RRF 3.5.0 rc3.
sudden change in jerk and acceleration after resume APF, it's set random value which is not in config and not in gcode.
gcode in which jerk is 300 mm/sec & acceleration 500 mm/s2, when i run the power failure sequence and after resume the print there is sudden vibration in X Y axis, so i am rum M204 to check it's acceleration and the result of it is 50000 mm/s2 and jerk is 600mm/s but gcode generated on jerk 300mm/s and acceleration 500 mm/s2.
