[BUG] Z Max Jerk cannot be set via M205

[siteswapjuggler]

Bug Description

Unable to set Z jerk within the firmware limitation via M205 command.

My Configurations

A custom CR-10S Pro configuration
myConfiguration.zip

Steps to Reproduce

1. connect via serial command
2. send M205 Z0.4

Expected behavior:

Z max jerk behing set

Actual behavior:

Z Max Jerk is not set and I receive "Z Max Jerk limited to 1"

Additional Information

This is whith classic Jerk Mode enable instead of Junction Deviation. A hack was applied by changing the value in the firmware and making a M502 te reset default parameters in the eeprom.

That's a little weird... warning message is sent only when you have LIMITED_JERK_EDITING enabled, but you don't have it. Again limit is twice DEFAULT_ZJERK then limit 1 means DEFAULT_ZJERK should be 0.5...but you have 0.4.
Now I have my printer busy, I'll try it as soon as it will terminate...

Oh sorry for that I was in the process to refine my config files and I sent you the one where I temporarely get rid of the problem by commenting #LIMITED_JERK_EDITING. My bad

mmm code is a little bit weird in lkimit check....
LIMIT(val, 1, max_limit[lim_axis]);

jerk seems to be limited between 1 and max...but max is 0.6 when 'LIMITED_JERK_EDITING' is defined...
Need to investigate more
