I am running Debian on my Thinkpad T420
The mesa is connected to the Ethernet port and when I connect to WLAN the connection to the MESA Card fails, it happens both with 10.10.10.10 and with 192.168.1.121.

Network:
IP 192.169.1.10 Mask: 255.0.0.0 Gate: 0.0.0.0
IP 10.10.10.11 Mask: 255.0.0.0 Gate: 0.0.0.0

Yes, I had the Ohmic sensing into the B encoder input on TB2.

That's OK with 7i96dpl.bit firmware (that has three separate encoder 'A' pins)

Change quotes around D3 (note the different appearance when you try to open the attached XML):

 

Could you post your hal files (IE the one that uses caxis.comp and the one with the orient.comp)?

I made a new xml with only the beckhoff EK1100. Now i get a new error

Another way to fix that is to chose the output polarity of the PWM
so its 0V at startup or watchdog bite (the STEP- pin) and then invert
the PWM in the hal file.

Its still a good idea to disable the spindle when LinuxCNC is not running
If the enable is an optocoupler input, a single resistor (R1)  will do
If its a 5V logic input, you need R2.

Safest would be to implement both (0 PWM at startup which is just a
wiring and hal change) and drive enable.

i got my 32 relay card today and changed something in the setup, i will test everything again later.

you can now use func:6 and set the datatype (new option) to bool, as register the 112 (0x70) and Values = 16

 

Soldering Iron or Wood Burner temps will melt skin. Had a friend when I was 9 or 10 who picked up his mum's Wood Burner Iron. Old Greg was a built different to everyone else. Pretty sure when he was working on a trawler he just pulled the tuna in with his bare hands, bet he would of tried to bite the heads off a few as well.

Actually I've just had another thought, what version of RPi imager are you using and what particular OS ?
I'm not a windows user and some people have had issues with RPi imager ?
Do you uncompress the downloaded file or just point RPi imager to the compressed file ?

Cheers

The images are not Raspbian based, so any pre imaging before writing to SD card will not work. This is mentioned in the sticky regarding the RPI images:

forum.linuxcnc.org/9-installing-linuxcnc...the-rpasberry-pi-4-5

Yeah I haven't really been happy with the way locales are setup. I would really like to come up with a solid solution and add that to the sticky mentioned above.

Regarding wireless:
wiki.debian.org/WiFi/HowToUse#Using_ifupdown_and_wireless-tools

I'm thinking network-manager and gnome network tools would make setting up networks somewhat easier.

You need to connect the relevant signals in your .hal file as in the example linked in the post above.

And where is the PLC of the machine written?

Not sure which PLC or which machine you are referring to.

Are these positional updates coming in during execution of a gcode program or while an individual MDI command is being executed?

There has been a short discussion about a similar project recently:
forum.linuxcnc.org/38-general-linuxcnc-q...robot-control#319033

you can take a look at this (non-realtime) component,
there i use sliders in python(qt5) to move my robot-joints.

it can also change the target position while moving, like you need.

github.com/multigcs/riocore/blob/main/ri...s/robojog/robojog.py

the script is not big and you already have an insight or you can use it as a basis, throw out qt and simply replace the inputs with ZeroMQ

I guess you didn't use the sysfs patch, this is required for Linuxcnc to recogonise that the environment is a real time one.

Easiest option will be to download the latest RPi4 image on the downloads page, has a 6.12.11 kernel (with the required sys_fs patch), Linuxcnc version 2.9.4. Might pay to backup your home directory.

Hi unknown,

Thank you for your suggestion. I have burnt that image, and I am able to ping my 7i96s on 10.10.10.10.

1. I am not able to go very far with PNCConf -- I have locale problem, using menu-config, I have set my default locale to en AU.UTF_8, still no go. There are existing posts on this problem, I will try it again.

2. This image does not come with WIFI preconfigured. I am using the Pi Imager to burnt it, and WIFI setting did not take effect.

Thank you and best regards,

....behai.

Should I connect one transformer lead to ground (the plug is 3-prong, the chassis is grounded steel)?

NO!
Connect ground only to box/chasis and to shielded cables.
Amps should be enough, move on.
Transformers can handle a lot of abuse, small overloads are no problem at all. After you power everything and have it running for 10-15 minutes, do check if it is heating from time to time, and even if it gets hot after and hour or two of work, as long as you can keep your palm on it, it is OK.
Human hand will have issues above 50 degree C, at 80 it burns like hell, and you will always know if the temp has gotten over 100 as your skin will remain attached to whatever you are touching, and fingers will turn shiny!
