Setting the MAX_JERK

[Emad-Shamsaki]

In the ini file, when i set the MAX_JERK, it will not be considered the first time.

I have to close and open linuxcnc, then the MAX_JERK will be applied.

What I observed was:

1. Changing the value of MAX_JERK in the ini and open linuxcnc
2. Still the previous set value of MAX_JERK is considered.
3. Close linuxcnc and open it again.
4. The new value value of MAX_JERK will be applied.

If someone has observed the similiar issue?
