7i76e: MPG and Analog inputs with pncconf?
then connect the scaled rate to the signal 'jog-speed'
analog_input -> scaled component -> jog-speed
You'll have to look up the actual pin names and component detail.
they would probably be best to put in the postgui_hal file
Other's may have better ideas.

i have this in the custom postui hal:
setp hm2_7i76e.0.7i76.0.0.analogin3-scalemax 460
net halui.maxjoganalog <= hm2_7i76e.0.7i76.0.0.analogin3 => halui.axis.jog-speed
something is a bit strange: if i start linuxcnc i can run a cnc programm without a homeing sequene (the last position is stored) but i can't move the machine with the mpg and the joystick.
with the arrow keys on the keybord it is possible directly after starting the machine.
mpg and the joystick are working after a homeing sequence, or after starting an stopping a ngc file!?

I am a bit confused as I have an up to date version of master and changing the value of halui.axis.jog-speed has no effect on the jog speed slider in Axis.trilobyte wrote:

I think this is a result of the 2.8's Joint-axis separation, you cannot jog axis until homed (only joints)

PCW is on the money. In master, you can't jog until you home all. This is to prevent a gantry from racking by moving a single joint on one side.
I did it like this with PCW help. But this is on a simple mill no dual motors.
setp axis.x.jog-enable true
setp joint.0.jog-enable true
## The above line is to be able to jog without homing ##

In master, you can't jog until you home all. This is
to prevent a gantry from racking by moving a single joint on
one side.
In general, the above statement is incorrect.
Joint jogging is allowed prior to homing except for special
cases where joints specify a synchronized final move by
using negative [JOINT_N]HOME_SEQUENCEs. In these cases,
joints that do *not* have a synchronized home sequence may be
jogged prior to homing.
See: linuxcnc.org/docs/master/html/config/ini....html#_home_sequence
Joint mode jogging of joints having a negative HOME_SEQUENCE
is disallowed. In common gantry applications, such jogging
can lead to misalignment (racking). Note that conventional
jogging in world coordinates is always available once a
machine is homed.The behavior is readily shown using the sim config (no
hardware required):
configs/sim/axis/gantry.ini
In this XYZY config, joints that correspond to the
Y coordinate (1 and 3) are synchronized; joints 0 (X) and
2 (Z) are not synchronized.

Strangely the original developers of the linuxcnc motion controller didn't give it an internal jograte or jog increment memory.
My understanding of this is because in the beginning it was a design requirement to be able to be controlled with multiple user interfaces at the same time - which typically used a switch mechanism to select jograte/increment which of course can't be automatically adjust by another interface..
Consequently, each ui has it's own idea of jograte/increment and there is no easy/universal way to communicate it around.
You would have to hack into AXIS to connect the halui jograte to AXIS's jograte - maybe possible within the .axisrc file.

Yes, it can be done with either .axisrc or a user_command_file.
This was asked for in this post so I assumed that a successful result meant that it had been achieved...
