Disable jog in joint mode. SOLVED was created by Miselph
Hi Folks,
I have a gantry based machine that is running nicely, EXCEPT that sometimes it drops back from axis (world?) to joint mode when you try and jog. At this point, if I have the X axis selected, it just moves one of my motors and racks the gantry. This could potentially be disastrous as it could lead to me damaging the gantry. So what I need it either a way of disabling jog in joint mode or preventing it from entering joint mode once the machine is homed.
Ideas please?

Hi
If you insert a single line into /usr/bin/axis (save a copy first) you can prevent jogging in joints mode
From line 2688 (approx)
This will prevent jog working in joints mode
Obviously as with any edit, it will be lost when Linuxcnc is next upgraded.
Test this carefully to make sure it does exactly what you want on your machine, I just did it in the gantry sim
regards

c.jog(*args)This will prevent jog working in joints mode

This is a improved solution, because it allows jogging in either mode until homed
regards
def jog(*args):
isHomed=True
for i,h in enumerate(s.homed):
if s.axis_mask & (1<<i):
isHomed=isHomed and h
if not manual_ok(): return
if not manual_tab_visible(): return
if joints_mode() and isHomed : return
ensure_mode(linuxcnc.MODE_MANUAL)
c.jog(*args)regards
