Robertspark's CNC Setup

what distro are you using?

what desktop application are you using?

you need to log out and back in before running
qtpyvcp -h qtpyvcp -i

I can get qtpuvcp to work and run up to there.

this line
sudo geany /etc/lightdm/lightdm.conf

is to set the automatic login.... it requires that you use the light desktop manager... and if you install the xfce desktop that should install...if you are using mate, qt or cinnamon or lxde I am not sure what desktop manager they use.

this was just my work in progress post... hence it has no text other than commands.

I installed a clean Debian bullseye install, built and installed linuxcnc then was working around to qtvcp....then wiped it when I was messing with probe basic as I wanted to check that my install of dependencies was correct to try another route.... hence this was not really set as a working config for anyone but just a list of commands that I was working through and tweaking

Thanks for this recipe, Robert!

I have a few, hopefully not too naive questions:

1. Is the dangling "libeditreadline-dev" just part of the sudo apt install, i.e. it should just follow "python3-pip"?

2. Referring to the following:
I assume this is optional just to improve real time performance? I've seen /etc/default/grub modified with the isolcpus parameters. What is /etc/lightdm/lightdm.conf?

3. Is this an installation of Probe Basic that will work with Bullseye and Python3 ? That's quite ground-breaking!

I think I understand the rest. After I hear back, I'll give it a try...

Thanks!
 

Did you edit your recipe? I think you clarified a few things since I saw it last. Thanks!

But, unless I missed it, I see no command to reboot. This would be necessary before checking the real time kernel with uname -a, correct?

 

I understand now that you are trying ... however I installed the linked image at the beginning of the post, only I left gnome instead of xfce. I try to install with xfce again I have a test disk, the working one is safe.

with gnome (never used it)

help.gnome.org/admin/system-admin-guide/...in-automatic.html.en

try

[sudo]
sudo geany /etc/gdm/custom.conf

[daemon]
AutomaticLoginEnable=True
AutomaticLogin=username
[/code]
Replace the username with the user that you want to be automatically logged in.

I got though the linuxcnc installtion with success! I can run axis!

But here are a few notes that might be helpful:

I rebooted after the first apt install (that included dpkg-dev linux-image-rt-amd64 linux-headers-rt-amd64.) I think that's necessary, correct?

For this step to succeed:
I had to install libtk-img
After the step above, you must cd .. to where the debs are, correct?

(I skipped the grub customization step because I wanted to do a before and after comparison. It didn't affect the installation.)

I didn't try it because it caused errors before, but would the no-docs option work?

I'm going to do a timeshift now, before installing qtpyvcp, so I can get back to a working lcnc if something happens. That might take a while...

Thanks again!
