How to configure a XHC-WHB04B pendant ?

Hi

I have try to change my config according to your information :

But like that i get any move from the pendant ??? so i did not understand why some user have issue with standard config ?

Is someone know more things about teleop ?

Or maybe this is on,ly related with XHC-WHB04-04 (4 axis variant)

Thanks a lot

So if i understand correctly with trivial kinematics the teleop mode is used only if machine is not homed ?

You mean after machine is homed this is no more used.

Signal managed by pendant is :
from Lcnc manual i see
So at the end i have not really understand what is really needed what is really needed.

Original component for machinekit did not use teleop mode at all, when i have start the conversion for Linuxcnc i get mpg working only using teleop mode, now i think this is maybe because i use a not homed machine for test ???

Another test done with machine homed and you are right pendant work very fine without the use of teleop, so i will now check for update the driver and remove or use teleop only if machine is not homed.

If some user are able to compile i have ask a PR for updated driver.

github.com/LinuxCNC/linuxcnc/pull/1049


hal config need to be restored :
hal config you need to add :

I know yes you are right but i have also check the driver for older unit and see nothing about changind mode.

github.com/LinuxCNC/linuxcnc/blob/master...er_comps/xhc-hb04.cc

I have push code to Github for manage both case (homed/unhomed)

I just debugged this part and it doesn't seem to work as expected. it will set teleop mode permanently (even before homed) here and I cannot drive beyond the designated area.

Does anyone know what the reason is why the pendant only works in teleop mode?
I checked the sourcecode and the implementation is certainly not correct right now.

Ok this is really broke, I modified the driver to expose joint signals as well. I'm just synchronizing the axis signal to joint signals (it could probably also be done in the configuration, but in the driver it seems to be straight forward).

before it's homed it will take the signals from joint.* once it's homed it will take the signals from axis.*
There's no need to manually switch between free / teleop mode at all it seems.

Also the M-Home option on the pendant doesn't seem to be useful for me, I use to home manually on my lathe (on the milling machine I do automatic homing), I'm going to expose new pins to allow homing the currently active axis (it's just an addition if someone doesn't want to use those pins just leave them unconnected)

I have added new pins to the driver home / unhome

- when wiring up the home / unhome joints it is possible to independently home all axis (and it's possible to drive outside the designated area for homing purpose)
- when pushing the M-Home button >1 sec it will send an unhome request
- when pushing the M-Home button <1 sec it will send a home request

the requests are sent when the button is released (I tested the haptic for this and it feels comfortable)

Those entries will be mandatory in order to be able to use the pendant when the machine is not homed.
(please note the joint 1 <-> joint 2 twist is related to my setup)

Todo:
- anyone volunteer to clean up the code? There should be a class for each timed button to tidy up the code. I'm absolutely overloaded at the moment on my side with various other tasks....
