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.

 

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

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 systemalso 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.

Thanks for that.

Dziękuję działa .

The trajectory seems a bit crude but as long as it works
For higher speeds and if the motor stutters you can try something like this.
Especially the starting and stopping can be smoother.
But don't overdo it, if it works, it works
 

Witam czy ten komputer nada się dla linuxcnc

Halfway down in this post rodw describes how to add a udev rule for /dev/EtherCAT0
forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

For the interface, there are many ways. I have the following in /etc/network/interfaces for my ethercat interface
It brings the enp2s0 interface up, without IP address

Check what's in syslog (sudo dmesg) if there are more problem

Hey, sowas in der art hab ich mir schon gedacht…
Dank dir, werde es nachher mal ausprobieren.
hast du dann nur DEFAULT_LINEAR_VELOCITY runtergesetzt oder auch noch andere werte und auf welchen wert hast du's runtergesetzt?
 

Did you try this?
Look for the heading : 2.8.2. Handler Patching - Subclassing Builtin Screens
linuxcnc.org/docs/stable/html/gui/qtvcp....cp:modifying-screens

Look for the direction on handler file placement.

Running linuxcnc from the terminal can give more info too.

you might try to read the firmware by glitching the voltage, I did that with an STM32F0 part in the past (but another application), I was even able to re-flash the image. I don't know if it also works with the G0, but you might try. Most importantly is to remove the capacitors.

I will take a photo of the wired USB version later this week since my pendants are in the shop
