Open a terminal and type while LinuxCNC is running
sensors
What are the temperatures shown?
Then, reboot and enter the BIOS and check what the voltages are in the "hardware monitor" section.

The LinuxCNC "Rigid Router" an open-source dual z-axis gantry machine

Category: CNC Machines

Thank you! Yep, they're 4590 extrusions, but I'm not sure who makes them. They can be ordered cut to length from 8020.net/45-4590.html though, which is super convenient. And yes, I agree, the flexibility of being able to loosen and move then re-tighten the bolts/t-nuts around is great!

Find some of those doughnut shaped ferrite rings and wind the pup wires twice through it.
Plenty of those on old equipment.

When can you use -not and when can you not use -not?

Category: HAL

You can list all pins by running LinuxCNC and issuing
this command in a terminal:

halcmd show pin > pins.txt

Which will create a file: pins.txt containing all available
pins in the running LinuxCNC configuration.

Remora - ethernet NVEM / EC300 / EC500 cnc board

Hey guys

After a bit of tinkering (was confused by the non-cpp repo) I got my NVEM setup. I attached my Servo on the X Joint and it works a treat in test mode (not on the actual machine). I went for the basic configuration without DMA and cl even though servos would certainly allow for that.. but thats a topic when the machine actually moves.

What I struggle is the inputs, limit switches and E-Stops. I attached them too. But I can't seem to register/read them. Granted this is my first play with LinuxCNC so I'm probably doing/looking at it wrong. But i tried to understand the PIN mapping and I'm a bit lost, where is it actually? The txt file that I upload only seems to name pins but doesnt actually map it? I looked at Mesa configurations and there it seems obvious because Pins are referenced in the HAL config. How is it here actually? Sorry I didnt find it mentioned in this thread.

Hi..trying to switch from Mach 3 on Windows XP ....I have the following on same PC but have wiped out Windows and Mach 3 and have only:

Debian GNU/Linux 12 (bookworm)
64 bit
xfce version 4.18
GTK Version 3.24.38
Kernel Version 6.1.0-23-rt-amd64
cpu Intel core 2 cpu 6400 @ 2.13 ghz x 2
Memory 3.8 GiB
GPU Mesa Intel 965Q (384.0 MiB)

and keep having linux stop working and bring me to login after a few changes on screen like open another file or open another application or even resize window..
Will be thankful for any help!!..

When can you use -not and when can you not use -not?

Category: HAL

Whether a component provides a '...-not' pin to invert a signal depends on the author of that particular component. You can use the 'Show HalConfiguration' tool to see all available hal pins loaded in your current config. Mesa provides those for many pins as a convenience but usually you will need to use a separate 'NOT' component that is included in the hal component library.

[edit]
Example:
#load the component
loadrt not
#start an instance
addf not.0 servo-thread

# usage
net your-signal                  <= some_pin_here           => not.0.in
net yoursignal-inverted     <=not.0.out => your_destination_pin

Wiring limit switches to MESA 7i96s

Category: Computers and Hardware

So for these switches I've bought they need supplied with 24v to operate? Is 24v input not too high voltage for the 7i96s? Would it be possible to wire them in normally open to the output pins with no supply voltage to the switches. Then when the limit switch is hit, there is a 5v signal from the 7i96s which results in linuxcnc recognising that a limit switch has been hit? Sorry for all the questions. I'm working on this project as part of my internship and I am very close to the deadline and still not finished so I'm starting to panic.

When can you use -not and when can you not use -not?

Category: HAL

I'm a bit of a newbie with HAL logic, and I wanted to change a 2 input OR gate to a 3 input OR gate so that when I toggle machine power off the spindle would also stop in addition to any table motion related to the servo's.

Initially I tried driving the 3rd input to the OR gate with motion-enable-not and this did not work, so I added an inverter driven with motion-enable and then used the output of the inverter (named stop-the-spindle) to drive the 3rd input of the OR gate and that works.

It's not obvious to me when you can append a signal with "-not" to invert the signal and when you can't?
If there is an obvious more elegant solution to my approach, please let me know.

I have included the hal file, with the original 2 input OR commented out and the new 3 input OR with inverter implemented. "#A12"  highlights the changes. Also attached logic diagram that shows the change in magenta.

I made another video :)
Most likely I also have a problem with electrical noise. When I turn on the lubrication pump of the spindle, the screen flashes (the display is connected with an hdmi cable). Also in two weeks twice lost connection with 7i73

Wiring limit switches to MESA 7i96s

Category: Computers and Hardware

4 Limit/home switches should be enough since LinuxCNCs soft limits
will prevent travel past machine limits.

Typically you would wire limit switches in a normally closed (NC) configuration
to 7I96S isolated inputs with the 7I96S input common wired to GND

so

+24V --> Switch common  --> switch NC contact --> 7I96S input

Normally closed is used so that a broken wire will result in an immediate fault

With normally closed contacts, you need to invert the hal inputs for the switches
