Hypertherm Powermax Voltage Divider, Preference for THAD-10

Category: Plasmac

It depends on your machine amperage. No scaling resistors are rwquired. Most people use 20:1 which gives a 200 volt full scale, 125 amps might be better at 30:1. (300 volts)
The thing is that the THCAD is rated for overvoltage of 500 volts. The voltage will only go over 200 volts on piercing when we do not care about the voltage then. During cutting voltage is between 100-170 volts. Keeping the max voltage range low means the readings are more accurate as more of the ADC's range is used. 50:1 is popular with a lot of non-linuxcnc THC's  (probably with a 0-5 volt ADC). That would be better for a THCAD5.

HOME_SEQUENCE = -1
on both your Y joints is needed. Refer to homing configuration in the docs.
Sometimes you need to invert the sign of the LATCH_VELOCITY to make it go the right way.

python hal glade

Yes, almost at the bottom:
AttributeError: Handler hal_button_pressed not found

So, in your .ui file there is a button that triggers the event "hal_button_pressed" and no handler for that event in the python.

Looking through the .ui file in a text editor:
cnc11.ui:34: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:49: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:93: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:108: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
cnc11.ui:123: <signal name="pressed" handler="hal_button_pressed" swapped="no"/>
Found 5 matches for "hal_button_pressed".

in the Python I see:
    def hal_button_pressed(self, widget, data=None):
        print ("on_button_press calllllllled")
        s.poll()

So you have written the handler, but in my editor the entire code body in the Python file appears to be triple-quoted (lines 15 and 120) and is highlighted in red. It may be that this is causing the whole handler file to be ignored.

Yes, there is no non-volatile information stored in the FPGA.

Have you connected the index-enable to the PID? That is intended to prevent a PID "bump".

Script to update 2.9.x ISO to use Linuxcnc Version 2.10 (master branch)

Category: Installing LinuxCNC

Cool, the ISO install points that file to the Linuxcnc.org repositories so deleting it let it us overwrite it to use buildbot2
Also we have a preferences file we delete to ensure Debian chose the Linuxcnc version at Linuxcnc.org, not the obsolete one in the Bookworm distribution. I don't think we need that here because  version 2.10 is > 2.94 (it worked for you)
If we do, we can edit the saved preferences version from the apt folder in your home folder or get it from the linuxcnc-livebuild (the binary versions are what we use, chroot is just for the builder)
github.com/LinuxCNC/linuxcnc-live-build/...worm/config/archives

Finally, I might add that this install is not best practice for apt. If you look at the Ethercat list.binary file, the key is explicitly referenced in the Deb archive line

Fusion 360 probe on probe_basic - Probe tripped during non-probe move

Category: General LinuxCNC Questions

As Andy says, the error is from Linuxcnc core, not the GUI.
I would be running the probing from probe basic and not get F360 to do anything with the probe (I didn't know you could)
I've used a probe with F360 and qtdragon and it all worked perfectly.

I should be able to just swap that fpga right? Assuming the EEPROM and whatever else is still good.

That worked. Was it supposed to overwrite the content of the linuxcnc-uspace.list?
That's what it did anyway. If you just wanted to add a new line at the end, "tee -a" is the answer.
Considering you did that in the previous commands with echo and >>

PCIe - No parport registered at "0x " . This is not Always an error.Continuing.

Category: Advanced Configuration

I wonder if there is a way to force these Sunix cards to load parport_pc driver and module from the I/O ports address?

So it will showup in dmesg as a proper enumerated parallel port.

It would make my life easier. I wrote a bash script to automate PCI card report creation ( forum.linuxcnc.org/18-computer/54368-pci...-box?start=30#325532 ) and I have a bunch of PCI cards to test and report, and some of them are Sunix.

Do any of you guys know a way?

Thanks. I checked the physical wiring and the MESA I/O config. The Limit switches were not patched correctly in I/O config. Was able to successfully home everything.

I just need to adjust the z settings because the spindle isn't going low enough to the table.

Re the ISO in a hurry, you could fork the Bookworm branch of Linuxcnc's live-build which I have maintained
github.com/LinuxCNC/linuxcnc-live-build
Follow the instructions to install and run the builder after cloning

Append your build script to this file 
github.com/LinuxCNC/linuxcnc-live-build/...linuxcnc.hook.chroot
or add a seperate file starting with 520-
clone your repository into a folder under /tmp and you should be able to  build and install anything you need.

You would need to delete this file which installs Linuxcnc from the repository at Linuxcnc.org
github.com/LinuxCNC/linuxcnc-live-build/...-lists/linuxcnc.list

Add any additional dependencies to 
github.com/LinuxCNC/linuxcnc-live-build/...e-lists/desktop.list

You probably need to delete all 6 files containing Linuxcnc in the name as these are the apt settings
github.com/LinuxCNC/linuxcnc-live-build/...worm/config/archives
note preempt_rt is a dependency of linuxcnc-uspace so you will need to explicitly install it.

This will install the Ethercat repositories :)

You may wish to update some of these fields
github.com/LinuxCNC/linuxcnc-live-build/...bookworm/auto/config

Note that the Debian live build inherits the version of Debian you run this on. eg if you run this on Trixie, you will get a Trixie ISO

If you have any questions, just ask.

Won't work, redirect of output is not done by superuser but by the invoking user.
Some solutions here stackoverflow.com/questions/84882/sudo-e...egedfile-doesnt-work

Ahh thanks, all my scripting has been done in installers as root
I tested this on my chromebook but there the user has root permissions
Something like this should then work as a script.
mkdir ~/apt
sudo cp -r /etc/apt/*.* ~/apt
sudo wget http://buildbot2.highlab.com/buildbot-archive-key.gpg /etc/apt/trusted.gpg.d
sudo rm -f /etc/apt/preferences.d/99linuxcnc-uspace.pref

@Endian,

I am not ready with the .iso, but you can try this archive. Unpack it where you want.
Then : ./install.sh

I didn't test it on a fresh .iso so i can not confirm it works straight away.
After installing goto : ~/linuxcnc/cmake/configs and do : ./run_axis_9

At your own risk:
repository.qtpyvcp.com/repo/linux-distro/lcnc_archive.tar

 

I will check it in my virtual machine and let you know but the best path will be to wait for your iso file because of all the components and stuff around ...
