Prusa Mini 4.0.2-4.0.5RC

Behavior

Prusa Mini Firmware (4.0.2 - 4.0.4) uses Junction Deviation
shown with M503

Recv: echo:Advanced: B<min_segment_time_us> S<min_feedrate> T<min_travel_feedrate> J<junc_dev>
Recv: echo:  M205 B20000.00 S0.00 T0.00 J0.02

But PrusaSlicer uses Jerk settings:

M205 X8.00 Y8.00 Z2.00 E10.00 ; sets the jerk limits, mm/sec
the values from slicer are ignored by the firmware.

@rtyr @DRracer ?

It is firmware issue, so it should be discussed here prusa3d/Prusa-Firmware-Buddy#292. Junction deviation is used only temporarily. Closing here.

ok. opend the ticket here. no reaction on firmware ticket... :-(

[rtyr]

I understand. We found a bug in classic jerk, it needs to be fixed by FW team.
