2.9.4 is based on Debian 12 so might have better luck asking on Debian forums.

Ich würde das mit OR2 ,in der Maschinen hal versuchen

Hi, 
i installed Linuxcnc 2.9.4 , and would like to use Mouse with bluetooth(logitech m350s).
kommand sudo apt update shows that adding this repository is not safe and disabled by default.
WHAT TO DO ?
 

Hi All,

My Maho 400E is still running an old version of Debian, with XFCE, that would have been the live CD back in about 2019. For my videos, I need to install simplescreenrecorder, as pointing a camera at the screen is lame.

I have tried:
sudo apt-add-repository ppa:maarten-baert/simplescreenrecorder
sudo apt update
This fails with "unable to locate simplescreenrecorder."

Please help with this. I seem to forget all linux knowledge the instant whatever I was trying to do gets done :/
Cheers,
Mark

 

да пожалуйста.
According to my observations, the queue error simply replaced the error  Probe tripped during non-probe move.

Wow, that's a lot to take in.

 

Sorry, I think I made too big a deal about some of this. That is a nice mill you've got. With a few tweaks it'll be fine.

Do the 220v lines going from the breaker box to the VFD also emit interference?

Yes.
Not sure how I overlooked this part of your question previously.

那是正确的。

Hallo ,
Ich möchte den 3d taster und den werkzeuglängen taster
nutzen ,die haben aber beide den gleichen Namen probe input pin. Den 3d taster habe ich auf pin 22 .funktioniert einwandfrei solange wie ich den pin 24 auskommentiert habe ,wenn ich ihn nicht auskommentiert habe startet das Programm nicht ,es kommt der Fehler probe pin bereits vergeben wie bekomme ich das gelöst .der eine wird in der Maschinen hal angegeben und der andere in der postgui.hal. Wie kann ich das Problem lösen?

Depends partly on how much data each device needs to transmit/receive, and how often. Theoretically, rs485 can multi-drop a large number of devices. I have used rs485 almost strictly via modbus protocol, but I see you do not mention modbus.

Using modbus rtu (rs485) with the mb2hal component, I was able to operate 1 VFD per converter/adapter. I was reading/writing approximately 16 parameters per VFD several times per second. I could not reliably run 2 VFDs on one converter. It seemed I was pushing the limits on bandwidth. But I had it running a lot slower - I think it was 9600, I needed that for better interference tolerance.

I used the ebyte NA111 ethernet bridge. They seem ok. Maybe a bit sensitive to interference. (I was using them in a large cabinet with one 30hp, one 10hp, two 5hp, and one 3hp 480VAC VFD, so there was plenty interference available and they've been running relatively reliably since about 4 month ago when they started using it.)

I also tried using the ebyte NE2-D11 but was very disappointed with it. It was so sensitive to interference it did not work with the Allen Bradley VFD I tried to interface. Well, it worked, but froze every time, the instant the VFD was started. I want to try it sometime on a sensor, or maybe even multiple sensors, I expect it might be fine for that.

I also have on another LinuxCNC installation a cheap USB to rs232 converter reading a position sensor about 50x per second nearly continuously since about 2016.

mesaflash --device device_name [options] --sserial


mesaflash --help gives more stuff

or you can try

man mesaflash

Weird, the test/setuid in mesaflash is very basic:

    if (seteuid(0) != 0) {
        printf("You need root privileges (or setuid root) to access PCI hardware\n");
        return -1;
    }

No idea how that can not fail for a normal user...

I have three RS485 devices (each operating at 115200 baud) and one BNO08x IMU, which supports UART at 3,000,000 baud, as well as I2C and SPI.Currently, I am using three USB-to-RS485 adapters and one USB-to-UART adapter to connect these devices. This setup is bulky and inconvenient.I am looking for a more integrated solution, such as a single controller or I/O board, that can communicate with all these devices independently and reduce cabling and USB usage.Any recommendations?

I have most of the electronics mounted to a piece of sheet metal, which is connected to main ground by the green/yellow terminal block by the contactor. Should I not do this?

That should be fine. I mount a lot of stuff to DIN rail like that on top of metal plate, seems to me sheet metal should be about the same. I try to keep low voltage DC circuits completely separate from AC circuits. Sometimes it is inconvenient to do so then I run them together a bit like you did. And then sometimes it just doesn't work then I have to separate them.

It seems as soon as there are some electronics directly connected to a PC's parallel port or PCIe slots a bit like these BOBs work, things get a lot more sensitive. Lately I've been using mostly ethernet connected 'BOBs' Mesa electronics or Beckhoff etherCAT because I rarely have interference troubles with those. (ethernet has very good isolation)

I used a BOB some years ago on a cnc plasma cutting table retrofit, I was happy with it. I probably went to the extreme shielding that BOB. Mounted it inside a die cast aluminum box that cost more than the BOB. All shielded cords to the die cast box, and no AC power into it. You should not need to go to that extreme. Plasma cutters make more interference than most VFDs.
