hal and whb04b-06 hand wheel

Hi
I'm new to Linux CNC, I walked through the hal tutorial but I'm not sure if I understand everything correctly and I would need help.
I want to attach the whb04b-06 hand wheel to a example machine (HAL and INI files attached).

I use LinuxCNC 2.8.1, and a Mesa 7i76e. The xhc-whb04b-6.hal is from the documentation and i use the included driver and the given udev rule for the dongle.


I modified the ini to load the xhc-whb04b-6.hal and also included some MDI_Commands for the macros.

When I started the machine I had some double assigned signals, for example:
testmachine.hal
net axis-select-x halui.axis.x.select
net axis-select-y halui.axis.y.select
net axis-select-z halui.axis.z.select

xhc-whb04b-6.hal
net pdnt.axis.X.select whb.halui.axis.x.select halui.axis.x.select
net pdnt.axis.y.select whb.halui.axis.y.select halui.axis.y.select
net pdnt.axis.Z.select whb.halui.axis.z.select halui.axis.z.select

The issue in this case seems the halui.axis.*.select signal
I commented out the lines in testmachine.hal and I can start the machine now.

How do I solve this issue correctly?
Because it doesnt work correctly, for example I can't jog the axis, if I try it, I jog the feed controll but not the selected axis.
I checked the show hal config, it seems the axis get selected but the counter doesn't get increased.

Thanks for any help.

Hi

First, you do the good things with comment out.

Second, i think you only need to push button continuous or step for select the correct mode.
At startup the device is used as feed-rate override

Third, for now it's not possible to use again feed-rate override after using con or step due to a problem added in the driver included in Linuxcnc 2.8/2.8.1
A PR is on the way but we need to wait for acceptance and i think wait for 2.8.2 release (for buildbot install)

After PR accepted you can also use "spindle override" using lead position, after go back from lead you get feed-rate override until you set again continuous/step (or return to lead off course)

Thank you very much, the continuous/step button solved the jog question.

The I still can change the feedrate with the buttons, so I'm good for now.

Thanks again.

Best regards,
Andreas
