XHC WHB04B development?

Category: General LinuxCNC Questions

If the interrupt endpoint is not continuously polled, you get the disconnects. But also the xhc-whb04b-6 component keeps it from disconnecting, at least in most situations. You can run that directly from the terminal, for instance with "xhc-whb04b-6 -a" to enable all logging, and you will see that the pendant will not disconnect.

So in this "easy" situation, there is not much difference between the three programs. We know that the pendant disconnects in a long-time stress test with the xhc-whb04b-6 component and LinuxCNC running. I'm not sure either of the other programs would do any better in similar situations.

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

Hey there

After having successfully used a NVEM flashed Remora via Ethernet for a while, I want to use an old 3d printer board (SKR E3 Mini v2.0) via SPI for my Plasma. It took me a while but eventually i got it to respond correctly via UART, and am currently sitting at

Starting the SERVO thread
Registering interrupt for interrupt number = 28
        power on Timer 2

## Entering IDLE state

Problem is that I struggle to make any communication via SPI. I think I triple checked every wire. As the SKR Mini Configuration in the repo seems to be for a version 1.2 of the board i modified the pins both in the firmware and config.txt, taking care of not using anything that may conflict with other function. But so far no nothing. 

Is there any way to approach debug/test anything further to narrow down why the comms doesn't seem to work?

Thanks a lot,
Alessandro

I mean, what do your program and usbhid-dump do that stop the disconnect/reconnects?
And why doesn't the whb04b component do the same?
Rhetorical question.

I looked briefly at the codes, but this is a big hurdle..

Configure Mesa 7i96s and pktuart with Omron MX2 (wj200)

Category: Advanced Configuration

I'm back !
With some good new !
I figured out my Problem. (read the fvck!ng manual :D )
For some reasons, you have to decrement the Register address by one for "run" and "reverse".

Now I'm struggling with the command-frequency.
I can run the Vdf using the Mesa pktuart. But I there is still a scaling of 2.56
If i send 10Hz to the Vdf, the displayed frequency on my OmronMx2 show me 25.6Hz
same as 100Hz. Vdf - 256 Hz

I checked all combinations of U_AB, U_BA, S_AB, S_BA, F_AB, F_BA.
Did i miss something or choose the wrong LSB/MSB ?

Same as Motor Current.
Heatsink-temperature works pretty well.

Na ja,
ich will Ehrlich sein.
Diese ist Luftgekühlt mit sicherheit sehr laut und hat wahrscheinlich Kohlebürsten.
Ich gehe nicht davon aus, das sie auch als Dauerläufer geeignet ist
Für den Preis bekommst du auch eine Chinaspindel mit FU Wassergekühlt.

Regarding the firmware for the pendant, I thought about trying to read it out with glitching or some other technique. But I have not seen the need for it so far. I did read out the firmware from the dongle, but also that was quite much work for what in theory should be simple:
github.com/finngineering/ch55x_firmware_extractor
The reverse engineering I have done for that is with Ghidra. But the dongle is based on the CH554 microprocessor, which is a "8051" type. And the support for that processor is not the best in Ghidra.

I'm not sure what differences you are asking about for the usbhid-dump Hakan. I haven't really checked the source, but I guess it's just polling the interrupt endpoint more or less the same as my test program and the xhc-whb04b-6 component. What would be interesting to know is if there are disconnects with all these program if left running long enough. Say, 1 day or so. Or if that happens only with the xhc-whb04b-6 component (and maybe only while LinuxCNC is running)... I could maybe leave it running overnight myself to check.

ooook. 

* Repasted CPU cooler.
* Took SSD out and wiped separately
* Reinstalled linuxcnc debian trixie package and did a couple tweaks from the links you posted.  All didnt work for me

Now im down to 21.2 microseconds in histogram with nobase.  10 glxgears and 4 x 4k youtube videos running.

HURCO KMB-1 Control Update

I replaced the spindle motor VFD, three phase outpout and the speed signal is 0-10v.
I notice that the speed varies in a random way and at say 1000 rpm, I get steps of 15 to 30 plus and minus.
The fuzzy line is an oscilloscope trace of the analogout5 pin on the 7i77.
The lower halscope trace is the same pin also nominally at 1000, offset and magnified to show what I can hear.
I have started the spindle using MDI with M3 S1000.
Any ideas what maye be going on?

Hi,
thanks for the feedback.
On the subject of E-Stop.
In CNC machines, E-Stop is triggered to prevent uncontrolled axis movements. 
In automated production machines with axes that move independently of each other, I agree with you. In most cases, an error message is sufficient here.

Hat jemand Erfahrung mit diesem Fräsmotor?
Eigentlich gefällt mir dieser recht gut.
Sowohl die Montagemöglichkeit als auch das Schnellwechselsystem gefällt mir.
Und mit ca. 1400W sollte da auch Aluminium zerspanbar sein.
Was mich etwas irritiert ist, das es auf YouTube kaum Informationen/Testberichte gibt.
Diejenigen, die einen ähnlichen Motor mal auf ihrer Fräse hatten,
sind auf eine HF-Spindel umgestiegen

Vielleicht gibt es hier ja jemanden, der diesen Fräsmotor im Einsatz hat und mit mir seine Erfahrung teilt

Danke und Grüße

So the drive didn't have Profile Position?
 

It has, I suppose, but I have only brief manual in chinese and can't configure driver properly.
I tried use configurations from other manufactures, but no luck.

Bom dia, eu tenho os procedimentos que vc precisa. Eu estou precisando da pasta C:NC500, poderia me enviar? 
Para carregar o software dele colocar o dip switch 1 a off e 2 a on, depois desliga a Rover. F4 manutenção, F9 inserir a senha 111, F6 backup software.
Após finalizar o carregamento do software que pode durar 10 min, desligar a máquina e colocar o dip switch 1 a in, e o 2 a off.

Found usbhid-dump github.com/DIGImend/usbhid-dump/tree/master
which already is in the linuxcnc system
# usbhid-dump --entry=all
also keeps the xhc from disconnecting.
What's the difference vs the component?
The whb04b component uses async transfers, but more?

FWIW, I put the usb dongle in my windows 11 computer. Disconnects/reconnects there also.
