XHC-HB04 wireless MPG pendant HAL module

I'm having a problem with my new xhc hb04. It's a wired unit. Turning the hand wheel clockwise moves as it should, i.e. 0.001 per click. However turning counter clockwise moves roughly 0.300 in the positive direction.

This is on a BBB with machinekit. linuxcnc 2.7.0~pre0

Running the 'xhc-hb04' command line utility gives the following:

It seems to me the counter clockwise click should produce -1 instead of +255

I thought I would apt-get update but there seems to be some trouble with that too:

machinekit and linuxcnc diverged quite some time ago, so we may not be able to give you the most accurate advice about your software.

It looks like machinekit has a fix for a bug that could be your bug, back in july 2015. I don't know how you determine the specific git version of your software when using machinekit. this bug and its fix were not forwarded upstream from machinekit to linuxcnc, so as of today linuxcnc lacks any similar bug fix. I don't have any of the relevant hardware so I can't do any testing regarding this bug.

which build of machinekit are you using on your bbb ,
i would concider grabbing the latest , that fix should be in the latest bbb build

Hello,

I have a working setup using the 5i25 by itself with the XHC-HB04 pendant. I'm trying to get a configuration going using the parallel port. The parallel port config works fine until I add the lines related to the pendant from the working 5i25 ini file.

Here is the error log. I can see that it's trying to link two pins to the same signal. I'm not sure what to do about it as it all works in the other configuration.

Any ideas?

Log Follows.

Thanks!

The problem is indicated by:

You likely used pncconf (or stepconf) which create numerous signals that are
connected to a source but not to a destination -- e.g,, it creates signals
which are not used.

So, in your config directory, find the hal file created by pncconf (or
stepconf) and look for a line like:
Remove that line or comment it out with a leading '#' character and try again

dgarrett,

Thank you very much. I will try that. I knew there something going on with the pins. I don't have enough experience with this to know what can safely be deleted and what can't. I went back and forth between the ini and hal files trying to see a connection as to where they are different.

As far as I can tell the hal files are indentical. That is what confuses me. One of them was indeed setup by stepconf as I wanted to use the paralell port. The 5i25 hal file was put together with help from andypugh and pcw. There is a thread here where I posted my hal file which works perfectly with the G540 and the 5i25. Smooth as silk. I realize that the 5i25 is overkilll for the G540, the paralell port is more than fast enough. I had already purchased the 5i25 before I understood that. I'm wanting to add probing routines to my mill and I thought that it would be simple matter to change over to the paralell port while I developed that capability.

It might be more effective to just make changes to the 5i25 file and work from there.

I don't spend enough time time working with the hal files to fully understand them. I have delved into them in the past but as soon as I get it working I don't work with the hal files enough to handle new problems.

I appreciate the time and effort you and the other folks here put into helping folks.

Regards,

Matt
