Hi there,
I`m actualy on optimizing my Probe Basic Installation.
One of an Error, which i had since the beginning was the following

After confirming this message i didn`t have any problems.
I run an Latency test and i think my system should be OK.
Further I`m using a MESA 7I96S, so it should be OK.

Is there something i can do?
Thanks a lot.
 

With the latest deb's from the Test directory it did not boot.

I downloaded the image you put "Armbian-unofficial_24.11.0-trunk_Orangepi5_bookworm_vendor_6.1.75_cinnamon_desktop-002.img" and big surprise, it stuck when booting.

I used the image "Armbian_24.8.1_Orangepi5_bookworm_vendor_6.1.75_cinnamon-backported-mesa_desktop.img" (the one in your link on page 35), and it boots and I can apply rt kernel to it.

The answer lies in the differences between the two non real time images. One boots and the other doesn't.

Do you think that if you applied configuration for rt-kernel on the image "Armbian_24.8.1_Orangepi5_bookworm_vendor_6.1.75_cinnamon-backported-mesa_desktop.img" it would result in deb's that would work?

I cannot test this right now but looking at this makes me wonder if it could actually be this easy to add 'M7' and 'M8' to the list of remap-able Mcodes (considering that according to the documentation 'M9' should not be a remap-able Mcode somebody already seems to have done or at least tried to do something like this)  :

 

remapping is certainly a valid option for sure. 

Yesterday, i did some further testing and at least i could solve the issue with my tootlable.

Thanks to all.


 

Good morning, friends

Does anyone have an example of how the Z axis is connected and controlled in the axis movement for controlling the height of a plasma torch using the THCAD2 board on the ENCA+ input of the 7i96s? I am developing it for other purposes, but I think the example can help. It needs to be in LinuxCNC 2.8.4, if anyone has an example, even a simple one, it will help.

 

 

I was able to start the spindle, direction works fine, but I have a problem with the speed.
My lathe max speed is 3000 rpm, when I set this speed, the pwm value is 0.999 so almost 1, which I think is correct.
When I set 700rpm, I get 0.23 on the pwm.value, which is also correct, however, the voltage measured between SP- and SPV is 5.8V so it spins way faster than it should.
How can I scale the value of the potentiometer so that between SP- and SPV I get the correct voltage.
Between SP- and SP+ I have 10.75V so this would mean 3000 rpm, so for 1500rpm, between SP- and SPV, I should have 5.37volts or smth like this.

Hi , is there any way to connect encoder to arduino to count encoder pulses and send the count to linuxcnc 
i want to use 2000ppr encoder so i want to use arduino insted of pc to count pulses
any help will be appreciated

a text message to the phone number and telegram did not work either. so.. get a working email please...

if your drives are M-II (SGD7S-xxxx10A with a couple of USB-A type connectors) then yes, YMTL2P will work

Hi Arciera,

Nice you can start lcnc now.

So how would I now make it load the gcode file through the optimizer? Everything looks just like it always does.
Start lcnc with open terminal, so you can verify the optimized gcode file is written trough the terminal output.
The gcode is optimized when you press the program run button.
This then starts the optimizer and saves a file in the ~/linuxcnc_trajectory_planner/cmake directory, named validate_xx.ngc. xx=random integer value.

Best worked for me is use a gcode file included a G64 P5 Q0. Then in next line a G61.

Then load the new produced file, and verify content.

I guess this is what made you comment that the install does not work?
Yes that is wrong filepath. The relative attached path"../../rtlib/motmod.so" is ok.


I think I may have found the underlying issue, something in the installation process of your repo seems to point motion.so to the 'lib' directory in the root folder (ie where a deb install would put them).
Maybe, the system would find them always in root lib dirs. I can remember me doing a "export" terminal command adding a
search dir to the system. Something like "sudo ldconfig".

In the link you can set your settings for the G64 P & Q values. With some more settings.
This is now compiled as fixed. To avoid confusion for me in earlyer stages of writing and testing the code.

Good luck. I hope you can get something out.





 

I think this topic revolves around “comfortability” and is not something that is urgent right now. For this reason, I don't think anything needs to be moved here.

But while we're on the subject of the window layout. Is there a possibility, via the Custom_config.yml or custom_probebasic.py, to make the code window a little narrower and the preview window wider, e.g. in the main mask?

Something like this:
 

Good morning Master PCW

I made the suggested change and it was not successful, an error appears, can you please help me?

The image below is before changing the line 214

 

The image below is after changing line 214

 

The image below is the error reported after the change

 

Attached are the error and hal configuration files


 

 

Please, can you help me?
 

I try it:
- Debian Version 6.1.0-26-rt-amd64
Rest as a screenshot.
Is there an easy command finding out all the versions? (for debian, i found "uname -r")
The rest as screenshots.
Hope this is the right info..
Debian (Xfce):

sudo apt update sayes everything is up todate

Thanks a lot

Just noticed this looks a bit odd:I guess this is what made you comment that the install does not work?

Hello everyone,Could you help me set up the control for my milling machine? The following setup is available:PC Lenovo ThinkCentre M91p i5 2400 8GB RAM
Mesa 7i96S Power supply 24V 10A or 2x 48V 7A
4 JMC closed loop stepper 3Nm / servos 180WThe milling machine is a self-built gantry designNow my questions:
0. Is there a well-documented example of setting up a control? There is a lot of information on the subject, but as a beginner it is very difficult to filter out the good explanations.
 

1. Are the axis designations fixed/relevant for LinuxCNC? On professional machines, manufacturers differ in X / Y

In the axis gantry.ini example, the Y-axis is doubled.

1. In the Axis example there is a special version gantry_jjog Do I understand correctly that with this version I can drive the double axis separately to a certain extent in order to align the portal?
2. End switch type Can someone recommend a good small end switch? I bought some but they are very large, about 8cm long. This is rather unfavorable for the construction. Alternatively, I have these small microswitches. Inductive limit switches are also an option. However, these are significantly more expensive and only come into question if there are real advantages. I don't see the accuracy as being so critical. With a 1K temperature change, I expect a difference of about 0.02mm over a length of 1500mm. So a sensor of 0.01mm is not really necessary.
3. End switch mounting/control If I attach an end switch to the moving part, I only need one switch for min and max, one cable and one input on the Mesa card. However, it cannot be distinguished whether min or max was triggered. Does this limit the function or is there anything else against this solution? Does anyone have an example of the wiring?
   
   That's it for now, but I'm sure I'll have more questions as we go along.

Thank you for your support.Best regards Erwin

I think I may have found the underlying issue, something in the installation process of your repo seems to point motion.so to the 'lib' directory in the root folder (ie where a deb install would put them). Since I only have rip installs on this machine the 'lib' directory in my rootfolder (ie /lib) contains nothing related to linuxcnc (eg there is no ' liblinuxcnchal.so.0' in root/lib/)

As a test I copied it into the root/lib folder:
and ran 'build.sh'. There is no longer an error about 'liblinuxcnchal.so.0' but about another one:

If I now also copy that one to the root/lib directory and run ./build.sh I can start the config.

So how would I now make it load the gcode file through the optimizer? Everything looks just like it always does.
