NEW BUILD, need help with e-stop in tklinuxcnc

Category: Basic Configuration

Hello friends, thanks to everyone for the help. Unfortunately, it didn't work out, and after two days, I gave up and looked for another solution. I stumbled across an Arduino in my boxes and decided to go with UGS on Raspberry (VNC) & GRBL on Arduino. Everything worked flawlessly right away. I'm satisfied. Thanks again to all and best wishes.

Thanks,
Dragan

Since you have problems with the Realtek adapters, here is a tip.
Add an Intel PCIe network adapter. Of course you need a free PCIe slot. With an X4 slot you can use a board with multiple interfaces.
And if you only have an M.2 slot you can use that forum.linuxcnc.org/18-computer/55782-adding-a-m-2-ethernet-port

You don't need a handler for what you want.

Here is an example that creates a led connected to 'halui.machine.is-on' and a button connected to 'halui.machine.on'

Single-stepping through a G-file

Category: General LinuxCNC Questions

I recently completed a wire EDM machine (not my design) and LinuxCNC runs it, and though I have a sw background, I have zero experience with it.
The very first job it's running, "First Cut" is very simple, checking that the hardware works, powering everything up, making a simple straight cut, then backing out and powering everything down. Because of all the new hardware, I want to single-step through this short job. See below.
The issues:
There are two buttons, "Run" and "Step." I first tried repeatedly pressing Stop and it seemed to work at first, but after about the fourth press, the program took off as though I'd pressed Run. An online reference (AI generated) said to press Step once, then repeatedly press Run, which will advance one line of G-code at a time. Thing is, when I press Step, Run grays out and cannot be pressed, so I don't understand (hence why I pressed Step repeatedly.)
On a related note, when pressing Step, I expected LinuxCNC to indicate the line of G-code that's being executed, but it does not. It's possible that's because I'm not using Step correctly, that it's never being activated, but I don't know.
Lastly, after pressing Step once or twice (don't remember), I get the following error message: "Cannot use axis values without a G code that uses them." I don't know what this means. [Edit: looking online, it appears that this is due to the line "X20" appearing along by itself, with no G-code ahead of it. A puzzle is how the program advanced all the way to the X20 line when I only pressed Step a couple times...]

Thanks! 

PS: the last line of the attached file is G30 (it was on the following page)

Hopefully this should cover it, and there will no need to have 2 pages per thread, per instance.

I edited my previous post to reflect that it does require running both those lines.
Thank you.

You can configure it as C axis using the caxis or orient component, and work in both functions, i.e. in velocity or position mode.

Fear not My Little Ones. We have an answer.


sudo rm /etc/{initramfs/post-update.d/,kernel/{postinst.d/,postrm.d/}}z50-raspi-firmware
sudo apt purge *raspi*
as noted by tommy above.


For a belts and braces check
sudo apt update


Now everything is good.
