Ethernet connection to Mesa 7i76e disconnecting on its own after one minute

Category: Plasmac

I should note that I have a HP EliteDesk 800 G1 that could never run Ethernet cards reliably
 for more than an hour or so UNTIL I upgraded the kernel to 7.x

It also requires:

disabling irq coalescing
isolcpus=3
and pinning the Ethernet IRQ to CPU 3

With these changes, I never get dropped packets even after months of uptime
with a PC used for compiling, youtube etc etc

Unable to Jog When HAL_ToggleBtn Active was created by scsmith1451

Unable to Jog When HAL_ToggleBtn Active

Category: General LinuxCNC Questions

I have a standalone gladevcp panel that has a HAL_ToggleBtn configured and hooked up. The button activates an output that turns on my X/Y laser crosshair for locating program X/Y start. When the button is activated, the laser turns on as expected, however, I cannot jog while the button is active.  As soon as I deactivate the toggle button, I can jog.

I know it is not related to the laser itself as I have an override switch on my machine that allows me to turn the laser on. When the switch is on, I can jog just fine.

This issue occurs with both AXIS and GMOCCAPY interfaces, so it is something in the bowels of LCNC.  

Anyone have any insight on this issue or a workaround?

Recommended way to implement spindle enable conditions?

Category: HAL

Lut5 is the best solution, especially when condition is type of "if a=true and b=false".
BTW. Beware situations when your spindle turns off when axis moved. It is more dengerous than continue when something fails.

Mint is based on Ubuntu, Ubuntu is not Debian.
They are similar, but have important differences.
You can install some packages from Debian in Ubuntu (and vice versa), but not all, and in this case, soon or later, something become not works...
Making hybrid distro is bad way and prayer for troubles.
Linuxcnc is Debian based, so we have to stay with Debian, even if we dont't like them.

I just checked the NAS, i do not have the headers.
You can install a new RT kernel and headers, or older one, but do not use 6.1 as it had some nasty latency issues (no idea what exact version it was).
Should be 6.17 by now so give that a try.

C axis milling cycles. Anyone written any?

Category: General LinuxCNC Questions

An alternative to consider would be using polar interpolation combined with a 'standard' set of macros for XY-type milling.

As I mentioned earlier, polar interpolation is not in main-line LCNC but there is a working configuration available on the forums:

forum.linuxcnc.org/10-advanced-configura...oling?start=0#225787

Nojo's implementation works, but I think the hurdle for anyone else to use it is that Nojo hard-coded the live tool offsets to match his particular machine.  I'd think some editing of the comp would be required to make it a universal component/scheme.  (i.e. use the currently loaded tool offset, not a fixed offset)

If you found an existing 'conversational' configuration/GUI you liked, polar interpolation should permit programming using that conversational system.

However, it's understandable if you're not interested in falling down the comp file development rabbit-hole and just want some working macros.

I might be wrong as I have only used Debian for years because Mint let me down a few years ago when Python 3 became mandatory for Linuxcnc and have not researched this for you.
I have a feeling that 6.13 is not a standard kernel used by Debian and therefore its derivatives. I believe that 6.12 was a release version.
So if it was not released, there won't be a readymade set of headers so you would need to compile the kernel to a Deb file which will output the headers as a Deb to install.

Debian is a much easier path. Just install the Cinamon desktop on install and you'll hardly miss Mint.

Control panel

Category: Show Your Stuff

Oh, can't believe I hadn't even searched for Syntec here.
I have literally spent the last week looking for used SK panels and trying to figure out what's what with them.I would be very, very interested in hearing more about your exact board and what's underneath your Arduino and next to it.  
Now, feel free to skip to the bottom as next I was asking questions that you have actually answered already - I just didn't know enough to realize:)

Skip From Here...
Newer SK panels have a small "matrix chip" surface mounted to the button side of the PCB (just inbetween button switches), older ones have a larger one on the backside (often a Holtek) and even older ones have a whole daughter board attached to the back side with a what Syntec calls a "decoder module". I always assumed the chip would spit out a proprietary serial link. I had no idea they were talking PS/2... Well, I thought perhaps the older ones were based on the Holtek model numbers.

But I have been trying to avoid newer boards because I wanted easy access to the matrix. I also had no idea the matrix is actually availble on the "HK Connector" - but that's how it looks from your picture. It looks like the Arduino is connecting to the HK. Or is the HK sending out PS/2 to your arduino? In which case your panel must indeed still have a "matrix chip somewhere" and your Arduino turns PS/2 into USB? 

Also, how do you control the button LEDs? 

If you could find time to share some more on how you made this work, I would be very grateful. I would mostly likely go this way as apart from ideally wanting more overide knobs, the SK4/6M panels have a really nice set of control buttons - plus the alphanumeric keys, too.

On a related note - as for turning the matrix into USB, when I asked AI about how to hack older SK panels it suggested this approach but to also make a combo USB protocol of HID plus a gamepad or joystick library. That way, supposedly, when doing the HAL connections you don't have to venture into weird combo USB presses to map the buttons that HID has no library for. So, you'd use HID for the regular stuff it already has and then gamepad library for everything "CNC" and it would just be passed through as button 1, button 2, etc. 

Also, I did talk to a Chinese vendor had to check back with the factory on the protocols and how open they actually are but between the language barrier and me only wanting to buy one, he kinda lost interest, haha. But I think he said they could deliver bare matrix, USB-HID and more.  

Skip To Here:)
[EDIT] I really should learn to read. You specifically explained the SK panel does both PS/2 and matrix. So, now I think the PS/2 signal may be coming into your arduino from that 5 pin connector in the corner of the board that says "to keyboard" and the matrix comes out of the HK Connector. Also, you even said the matrix is shared for both buttons and LEDs. So, there we have it:) What wonderful detective work you have done to make these panels work! 
So... would you be inclined to share the code and pin mapping to help others along:)?

Every time I boot LinuxCNC, the Xg54 position reading increase 256

Category: General LinuxCNC Questions

First the Linuxcnc version you quote is invalid. What is it really?
Second, 256  is a very signiicant number for computers because an 8 bit number (1 byte) counts from 0-255 which a computer's way of counting from 1-256.
The  G54 values are stored in the var file. I could not see exactly what us the varibale number on a quick look. I would check this after you close to make sure its not being incremented on close,

My guess is that Linuxcnc will be OK but somehow outside of LinuxCNC, your encoder value is incremented by 1 X  8 bit byte.

Hi there.

When choosing the PROBE tab with the file in the indicated directory, a pop-up window comes with this error:
"Traceback (most recent call last):

(Attached the report)

In the other hand, I´ve set 99 tool number to probe, and after running a program if I go to TOOL tab, select it and push the M61 button to choose, it runs pretty good despite the down yellow line appears with the "cannot switch pages while in AUTO mode"
