Hello,

I just installed my first Linux version on an old Thinkcentre i have laying around. Iam planning onbuilding a new CNC using LinuxCNC so I thought maybe I can and lear how to use it before i finish my CNC. Kinda just to get used to Linux.

So after like 2 hours I finally managed to get debian 12.10.0 running on my Thinkcentre. Then I started to follow the instructions on the LinuxCNC page.

I did the updates:
sudo apt-get update
sudo apt-get dist-upgrade

Then I installed the Preempt-RT kernel
sudo apt-get install linux-image-rt-amd64

everything worked fine. After the restart it selected the right linux RT version.

So the issue starts here.
 

If i click on the link for the linuxcnc-install.sh file it doesnt download anything. So where exactly do I get the script? Iam probably just to stupid to understand it.
Also chmod +x linuxcnc-install.sh doesnt work. I have even tried opening an txt.file and naming it linuxcnc.install.sh with the script from the browser. But still nothing.

Found another thread with simillar issue
$ chmod +x besnik/home/Downloads/linuxcnc-install.sh
Or better yet
$ cd besnik/home/Downloads/
$ chmod +x linuxcnc-install.sh

Always says No such file or directory.

Does anyone have an idea what I am missing I can already deel its something easy to fix I just dont see it. Kinda embarrassing asking for help

Python's stacktraces are not helpful.

I always miss Java's verbose and informative stacktraces whenever Python enters my life (generally via apt (which seems to have Python components) and LinuxCNC, which seems to have a lot of Python)

Perl might be the "duct tape of the internet", but Python is definitely the duct tape of GNU/Linux.

Perhaps chmod -R 777 user_tabs will fix it.

Otherwise I have literally no clue.

Moved to QtPyVCP section.

After installing and configuring Probe Basic I always get these errors, the user_tabs folder is present:
Traceback (most recent call last):

Maybe someone can shed some light on the matter for me.

Normally we would not use hex files at all because the standard way to update
would be over serial. I will look into why the serial update fails.

Greetings,

I only gave you half of the equation.

Insert G64 P0.001 into the startup line at the top of the program.

The P parameter is what does the work.

If this cures the issue, modify your post to insert it automatically.

Cheers,

Dave

Thanks Snow,

You always do a great job, i'm just a bit different.

Using the laser button is 3 clicks and wait for lag. first to "laser" then "mark edge" then "set origin", then the machine moves.

With the user button, its a one click and the machine moves to where i need it, zero's, and i'm ready to start cutting. the code i'm using is the one I found worked many years ago and i have just kept it. i also have another button used for the air scribe offset (albeit still a work in progress). I have only had this issue since the update to 2.9.4.

My normal operation flow goes.
home machine
sheet on machine
import drawing
align x,y using laser
click laser offset to zero torch on where i lined up laser pointer
frame to check cut file will fit (done alot when cutting multiple parts from sheets that have already been cut)
then cut

I'll try the new code now and see how it all goes.
new code is G10 L20 P0 X0 Y0 \ G0 X-2.5 Y104.3 \ G10 L20 P0 X0 Y0
Works perfectly, thanks again Snow !!

The plants can be pretty rough as well.
The beer's good, no I no longer indulge.
The back roads are great for a fang & scratch.
Funny thing is Australia is hot & dry but Aussies have a rep for being pretty quick on a wet circuit, go figure.
Another good thing is the drive in bottle shops, ya can get beer, wine, spirits and chips and other party supplies without having to get out of your car. Unlike some nanny state countries where you can't even buy beer & spirits in the same place. The same country that was so scared of Trump they voted in the same party that made them a laughing stock that was led by Castro's son and used to club baby seals. The same country that you can't walk the street with a beer or other drink in your hand, and you pay for stuff with loonies. Oh and don't ask for a hamburger with the lot, they can't fathom it.

To be fair we only got electricity yesterday and fire the week before. Fresh water, that's for cowards that are scared to go to creek to grab some water cos there might be a salty wanting to eat you. Or a shark that wants to bite a leg off, a blue ring that wants to end your day.

Dear linuxcnc users,
i want to introduce my new open source project based on the W5100S-EVB-PICO . ~10 USD (raspberry pico clone)

features:
1 to 8 step generator with 255KHz maximum output in this version, (possible higher freq) enough for 15m/min with 0.001mm
1 to 8 quadrature encoder counter with 12.5MHz theoretical maximum counting frequency.

current version in the github page is support 4 stepgen and 4 encoders
linuxcnc driver supports multiple instances
planned direct SPI communication with raspberry-pi4 (with normal pico)

github: stepgen-encoder

Thanks
Best regards
Milko

Nice, thanks for sharing.

Hello everyone,

i was facing the same problem preview plot bug in LinuxCNC 2.9.4 with Gmoccapy 3.4.9 as described in this thread:  Question: Gmoccapy 3.4.2 and touchscreen
Preview only moves a couple of mm then stops.

So i decided to change the gremlin.py to use the Gtk3 Gestures. With the modified version you can rotate the preview with one finger again, but also zoom in and out with pinch gestures as well as pan with two fingers. In X, Y, Z view the rotation is locked, only zoom + pan. As of right now it will disable the mouse, but my machine only has the touchscreen so for me its no problem.

~$xinput list show my touchscreen as:

No further driver installed. Tested with fresh 2.9.4 live iso.

Just replace gremlin.py in /usr/lib/python3/dist-packages/

I just wanted to drop this file in here in case someone has the same problem. It does not work in Axis though! There the preview jumps to a random place, but it is the same behaviour with the original gremlin.

Also made a small video:

That looks correct.

thank you i will try this out.

Greetings,

I think I had a similar situation.

I needed to activate G64 to tell the controller not to move until the previous event had finished it's travel.

Cheers,

Dave
