Hi,
I have a question about the configuration of the XHC WHB04B-06.
I already asked this question in the German forum but unfortunately did not receive an answer.
First of all, the handwheel works perfectly except for the rotary knob button.
Here I can only set the increments. But I also want to control the feed rates.

I think the settings need to be adjusted here:

# GUI feed rate related signals can be used when program is running moving GUI slider
net pdnt.feed-override.scale whb.halui.feed-override.scale halui.feed-override.scale # needed for both FeedOverride+/- and rotary knob button
net pdnt.max-velocity.value whb.halui.max-velocity.value halui.max-velocity.value # needed for Mpg mode : button feed position% * max-velocity = Mpg feedrate

# take feed override min/max values from/to the GUI
net pdnt.feed-override.value halui.feed-override.value whb.halui.feed-override.value # GUI feed rate related signals
net pdnt.feed-override.increase whb.halui.feed-override.increase halui.feed-override.increase
net pdnt.feed-override.decrease whb.halui.feed-override.decrease halui.feed-override.decrease


I just don't know which ones?
 

See the "buttons" section:
linuxcnc.org/docs/stable/html/man/man1/x...6.1.html#HAL%20USAGE

The default config is set up just to say "macroN" when you press a button.
If you want to do somethng when you press the button you need to change (debug, macro4) to a bit of G-code (or a call to a subroutine) that has the desired affect.

Hi,
ich hätte auch Fragen zum XHC und der Titel passt auch zu meiner Frage.
Ich hoffe die wurde nicht schon 1000x gestellt.
Derzeit nutze ich die .hal Vorlage aus der Linuxcnc Dokumentation.
Die Oberfläche ist CMOCCAPY
Ich würde gerne den Vorschubregel Knopf für Eilgang UND Vorschub nutzen.
Derzeit funktionieren nur die Incremente.
Wie müsste ich die Vorlage anpassen?

# Minimale/Maximale Werte für die Vorschubüberschreibung aus/in die GUI übernehmen
net pdnt.feed-override.value halui.feed-override.value whb.halui.feed-override.value # GUI-bezogene Signale für die Vorschubrate
net pdnt.feed-override.increase whb.halui.feed-override.increase halui.feed-override.increase
net pdnt.feed-override.decrease whb.halui.feed-override.decrease halui.feed-override.decrease

Besten Dank schon mal im Voraus.





 

Is there a difference between the configuration of the XHC-WHB04B-4 and the XHC-WHB04B-6. I understand there may be more buttons on the -6 but I'm more concerned about the core functionality of the MPG wheel, axis selection switch, and the step scale switch. I got it working in Axis sim but not sure I have it working perfectly. I started out with the example config from the documentation page. I did notice that hitting the "W-HOME" button invoked a Macro 4 popup in Axis, which seemed odd.

Usually due to naming errors, like spindle.enable should be spindle.0.enable, axis should be joints, etc.

Hi Tommy

Thank you for the heads up, I did some reading prior to get the vfd signal going and did hear to other peoples warnings on this forum so I've got an abs component running successfully. The issue is the pendant won't send rpm signal to analogue output 5 were as axis will ?

It is enough to start a chain reaction, same as throwing a wrench on any complicated machinery, no matter how small.

As for the subject, i used a Mesa 7i77 to drive a car power amplifier as a servo drive, so i had to limit voltage from going above +-2V and it worked pretty good, given the limited current those amplifiers can deliver (it will trigger over current on any faster move), but i forgot how i did the limiting in hal, pretty sure it was the MAX and MIN OUTPUT set to 2, but fuzzy on what else.
I also did 0 to +5V and it also worked, but tried with those arduino PWM drives and that did not work as analog and PWM are not the same, you can do analog from PWM easily with an RC, but not vice versa.
This was probably 10 or more years ago...

Ouch! been there done that. I'm still amazed a 10mA signal could smoke like that.

A friendly warning, Mesa 7i77 can output negative voltages up to -10V, and most VFD's will complain about it vigorously and sometimes with smoke signals, so it would be advisable to wait for someone more experienced on how to limit the Mesa output going negative by probably editing the hal file and/or even using ABS component.

Hello all

I installed a 0-10v signal from my MESA 7i77 board to the vfd to control rpm and my XHC-W04B-6 pendant will enable the spindle but wont tell the spindle to turn at default spindle speed set in the ini file .  Any help would be appreciated.

Aha. Many thanks - commenting out that duplicated line did the trick, so I now have the machine moving in closed loop, homing correctly and e-stopping safely. That's a great step forward and it feels as if I'm getting close to getting this sorted out.

I now have to get the xhc-whb04b-6 MPG connected up (currently commented out) and the spindle vfd doesn't respond, so I'll need to check that out too.

Andy Pugh's macros don't show up in my GUI. I have the tab showing up but clicking on it does nothing - none of the graphics appear. There are several gmoccapy lathe sims that work but something's not right in my setup. Again, I'm not clear what files need to be where and what configs need to be set up. Is there any documentation for the lathe macros that I can refer to?

Many thanks
