This fixes #1000 (comment)

resolves #1000

Have you checked you solution also with a non trivial kinematics?
IMHO you will need to check the kinematics type, as for jogging in a non trivial kinematics and state not homed, you will need to display the JOINT Button and in a trivial kinematics the axis BUTTON.

@gmoccapy When there is any tripped limit switch, then it would be mentioned in stat.limit, right?
In that case I enable the "ignore limit" checkbox to be able to switch on the machine and move away from the limit switch.
The action is the same as when toggling the estop (except the button manipulation).
'Trivial kinematics' also has its limit switches on joints, so that makes no difference IMHO.

Here is it done in nearly the same way:

linuxcnc/lib/python/rs274/glcanon.py

Lines 1041 to 1044 in 9d0954a

	def one_or_more_on_limit(self):
	for i in range (self.stat.joints):
	if self.stat.limit[i]: return True
	return False

Now it is working perfectly. I verified this on a real machine.

Ready to go then?

Yes!
