We have very similar goals. In the future, I also want an ATC and a fiber laser machine for metal cutting. I’ll be keeping an eye on BidSpotter as you mentioned, but I think I’ll end up buying the resonator and all the necessary parts for the fiber laser from some affordable Chinese supplier. Thank you so much for your support with the MPG, you’re a legend!

XHC-WH04b USB not detected in front port

Category: General LinuxCNC Questions

FOUND IT!

After 3 years since I bought the MPG, finally found the cause and solution of the issue of not being recognized on some (or all in my case) USB ports. It probably also solve if somebody got connection problems.

The main issue is that the XHC WHB04b receptor needs quite a lot of power (comparing to other USBs) to maintain a stable connection, and not all USB ports does provide such high current. So if the connection is not stable because the power issure, the kernel does not detect it. This can also happen on windows, but the windows specific drivers solve it on some cases. My computer is an industrial mini PC with external 12V PSU, so all USBs get their 5V from the main board. On desktop computers, front forts have usually lower power than rear ones, causing the issue.

There are a couple of really easy and cheap solutions:
-Use an USB HUB with external 5V power supply
-Use a Y cable (2 male, 1 female USB) either with both male USB connectors to the computer or the power only connector to a 5V PSU.

XHC-WHB04B-04 Got it working

Category: Advanced Configuration

You're welcome, I'm glad you got it worked out. On the topic of separate machines, the logic is there and holds water; it's almost like multiprocess welders, unless you drop some serious money, you're compromising. And I, for one reason or another in the past, needed both couldn't afford both, or didnt have the space, I know I'm basically handicapping the machine, whichever gui is loaded but not ot the point, parts are out spec, or customers bringing stuff back. The plan is to build another machine for a 3 to 5k fiber laser, ditch the plasma altogether, and mount an ATC spindle and vacuum holding to this current one. I've been really good this year, hopefully a smoking deal comes through on BidSpotter for a laser source. This is the 5th iteration of a CNC gantry-style machine I've built. I went HAM on it just because I'm tired of being tired of not being satisfied with it.  The .5" flat bar on top has a reference shoulder machined in and a skimmed on both sides im gonna use jack screws every 12" or so in pairs to get this thing as coplanar, square and level as pyhics will allow, me to and then use a metalized epoxy to bed the bar to the frame and finaly a few stitch welds to lock it in.  ce la vie i gues. Your set up is pretty gangster

First of all, thank you so much for your effort and for sharing your files—without them I never would have gotten mine working.
I learned the hard way that it’s not practical to have one machine serve as both a router and a plasma cutter, so I developed a very affordable “plasma router” that works perfectly, and now I keep the two machines separate.
I’m leaving a video so you can see it running in case it helps, and a link where you can download the 3D model and wiring diagrams. I’m sharing it as open-hardware to give back a little of the much that the community—and generous acts like yours—have given me.

I don't use the pendant anymore and rely on a touch screen and wireless keyboard because my machine is a dual-use plasma /router, and I couldn't get plasmac.comp to play nice with the pendant. But once I get the table put back together, I will revisit and see if the berry is worth the squeeze.

[SOLVED] XHC-WHB04B-6 on LinuxCNC 2.9.6 (QtDragonHD + 7i96S) — Beginner notes
(I am sharing the exact steps I followed, written simply. Many threads assume advanced users; I am a beginner.)My machine / system
  • Gantry router XYYZ (dual Y motors), work area approx. 1300 x 1210 mm
  • Controller: Mesa 7i96S (Ethernet, step/dir)
  • Spindle: 2.2 kW, 24,000 RPM
  • UI: QtVCP / QtDragon_HD
  • OS: Raspberry Pi 5, Debian 12 (Bookworm)
  • LinuxCNC 2.9.6
What actually fixed it (short version)
  1. Load the pendant HAL file as a HALFILE (before the post-GUI), same as the donor machine.
  2. Add MDI_COMMAND lines under [HALUI] so pins halui.mdi-command-XX exist.
  3. Keep qtvcp_postgui.hal clean (only GUI signals, no pendant driver).
  4. In my case, moving the WHB USB dongle to another port made the wheel/jog and DRO updates work.
STEP 1 — Copy the pendant HAL file
Place xhc-whb04b-6.hal in your config folder (the same folder that has your .ini and main .hal), e.g.:
~/linuxcnc/configs/YOUR-MACHINE/xhc-whb04b-6.hal
STEP 2 — Load the pendant before the post-GUI
Open your .ini and in the [HAL] section add this line and keep this exact order:
[HAL]
HALUI = halui
HALFILE = CNC-CARPINTERA.hal
HALFILE = custom.hal
HALFILE = xhc-whb04b-6.hal ; <<< NEW: load the pendant here
POSTGUI_HALFILE = qtvcp_postgui.hal ; keep this AFTER
SHUTDOWN = shutdown.hal
Important: do not load the WHB driver inside qtvcp_postgui.hal.STEP 3 — Create MDI pins under [HALUI]
In the same .ini, find (or create) the [HALUI] section and paste this block right under it:
[HALUI]
MDI_COMMAND = (DEBUG,<1>) ; <<< NEW (good for testing macros)
MDI_COMMAND = G10 L20 P0 X[#<_x>/2.0] ; <<< NEW (zero X at part center)
MDI_COMMAND = G10 L20 P0 Y[#<_y>/2.0] ; <<< NEW (zero Y at part center)
MDI_COMMAND = (DEBUG,<4>) ; <<< NEW
MDI_COMMAND = (DEBUG,<5>) ; <<< NEW
MDI_COMMAND = G10 L20 P0 X0 ; <<< NEW (Zero X)
MDI_COMMAND = G10 L20 P0 Y0 ; <<< NEW (Zero Y)
MDI_COMMAND = G10 L20 P0 Z0 ; <<< NEW (Zero Z)
This creates halui.mdi-command-00..07 (indexes follow the order above).
Add more MDI_COMMAND lines if your xhc-whb04b-6.hal uses higher indices.Notes so jogging actually works
  • E-STOP released, Machine ON
  • Manual mode
  • Fully homed (for XYYZ: X, Y1, Y2, Z)
  • On the pendant, use Continuous, or Step + Step size
  • If the wheel does nothing or DRO does not update: try a different USB port/dongle (this was the final fix for me)
Thanks and request
Many thanks to the original thread’s author for sharing files and guidance.
If possible, could you post a short summary of the final button mapping (what each macro-N does, Continuous/Step, ABS/REL, etc.)? That would help beginners keep their configs consistent.If anyone needs it, I can share my final .ini, xhc-whb04b-6.hal, and a minimal qtvcp_postgui.hal exactly as they ended up.

Axis configuration not fully working on 2.9.6

Category: AXIS

So I don't have to worry about the pins not being created?


No. Hal connections are created on startup when the hal files are read. If a hal pin used in any of your hal files was missing the config would not start at all. So your problem is not because of 'signals not being connected correctly'.
One thing to do is start your config from the terminal and check the output in the terminal. Another is to check the XHC WHB04B hal component using the halshow tool to confirm button press events are actually reaching your hal connections.

Axis configuration not fully working on 2.9.6

Category: AXIS

Hey guys,
my config works as i want it on linuxcnc 2.9.4. After updating to 2.9.5 (or 2.9.6) it does not anymore. It mainly is the pendant that is not working as before. I use a china pendant (XHC WHB04B). Most buttons don't work anymore. For example when staring my machine, I hit the "reset" button. With version 2.9.4 I can home my machine after that. With 2.9.6 nothing happens. Control via GUI seems to work just fine.
I think the problem must be related to one of these, or maybe both points in the changelog:
  • halui: on startup, set the first configured axis as ‘is-selected’ instead of X
  • halui: Don’t create ‘halui.axis.’- pins for unconfigured axes
I looked at all created HAL pins under 2.9.4 and 2.9.6. I compared the output and found some missing pins under 2.9.6. I don't see why i would need these pins, but I figured it maybe where my error is? See the atteched pic for the missing pins.
I hope someone of the pros on this forum can help me. I don't know how to solve this on my own.

Setting up kinematics for my Ballscrew articulated B-axis

Category: Basic Configuration

Ok, sorry for the images. Anyway, I performed all the math on Google Sheets, so you can enter the B-axis position on the ball screw, and it will provide you with the spindle angle, the tooltip x-offset, and the tooltip z-offset. The range of travel for the B-axis is 0 to 305mm. You can enter this in cell Y11, and it will spit out the results. I have also illustrated the drawings better here so that hopefully you can understand. Here is the link . I have looked at the Kinematics tutorial on the website, but I just learn better if I can see someone do a working example. After hours of reading that with Gemini helping with some of the explanations, I don't know how to start writing the code. Anyway, from the tutorial I posted earlier, there is an image of this person's kinematicsInverse function, which I will insert below.

File Attachment:


From what I've understood, the job of this function is to understand the required tool tip movement and spit out the number of steps each axis motor needs to make, correct? If that is correct, I should be able to modify the trigonometry here to accommodate my ballscrew articulated B-axis and get this going, hopefully. Because his setup also has an XYZAB setup similar to mine.

"pwm/dir" (Out1) switches for spindle CCW

Category: Basic Configuration

Hi there
A question about my configuration:
1. I have a HF milling spindle which needs only to turns clockwise. The PWM canal (Out0) works fine. My config for "pwm/dir" (Out1) is set to a relay output (P17/"GPIO7"). The relay should be on when CW is commanded but here it is on when CCW is commanded. How config it so that the relay switch on when CW is commanded?

Enable / Disable Output when Spindle is ON /OFF

Category: Advanced Configuration

Thanks for the tips! 

I applied it to my setup and realized that the 
xhc-whb04b-6 Hal code already used the spindle valve signal.
"
net pdnt.spindle.is-on whb.halui.spindle.is-on spindle.0.on"
After fiddling for some time, I came up with 
"net pdnt.spindle.is-on => hm2_7i76e.0.7i76.0.0.output-11" 

In my Hal file. Everything is working now. Thanks! :)

scale: already exists

./whb04b.hal:20: insmod for scale failed, returned -1

You are probably trying to "loadrt scale" in two different places.
You need to combine them into one "loadrt" that loads as many as needed.

(Or you can use HAL_TWOPASS, but that may be more work)

Thanks very much Finnengineering.

That's good to hear. I'll have another play with it in Halshow and see if I can set that pin.
