If you add numbered parameters to your .var file, the added variable numbers should become persistent.

[edit]

 
www.linuxcnc.org/docs/html/gcode/overvie...:numbered-parameters

As an example if you want parameter #1000 to be persistent you would add this line to the top of your .var file (mind the <tab> in between the two numbers and make sure LinuxCNC is not running when you modify the file):
1000    0.0

What should I do to ensure that the values ​​I write are not lost and persist when Linuxcnc is turned off and on?

modifying qtdragon - depending on what version of linuxcnc you are using...
open a terminal and type 'qtvcp copy' no quotes

A dialog for copying screen code to the user configuration folder should display.

looks like this:

You have W3 down (you picture is upside down)
so not supplying 5V to the 7I76 You need W3 up
if the 7I76 is Jumpered to get cable 5V (7I76 W2 left)

W3 is one of the group of 3 jumpers under P1 but closest to
P2

The gamepad also works fine using jstest. So Linux has no problem with it - just something wrong with linuxcnc seeing it

Category: General LinuxCNC Questions

1, Yes, the 7i76 has both 5V and field power
2. I believe that the flat cable is correct
3. The 7i76 is jumpered for power from the fpga card, however,
I am not certain of the 7c81 jumper w3. Is it supposed to be closer to the ribbon cable or farther from the ribbon cable.
The manual for the 7c81 says,
"Hardware setup jumper positions assume that the 7I98 card is oriented in an upright position, that is, with the Ethernet connector towards the left and the I/O connectors towards the right."

I'm going to study the manual, but I've never done it, I'll probably have several questions as I go along, I ask you to be patient with me, but I thank you for taking the time to answer

Thanks for the info. I tried modifying qtdragon, I think where I got stuck is not being able to find the .ui file to edit, it wasn't in the config folder. It would be great to have a look at that. I would want support for a tool height sensor and can program that if you mean qtdragon does not include it.

Can you elaborate on EtherCAT and how you set it up?

Tool resets to Z0 when starting program without being told to

Having some issues with running some Gcode. I'm using fusion360 and when I single step through the ngc on linuxcnc the Z axis plunges to 0 without being told to in the Gcode.

The origin of the the piece is a known position on the spoil board, its surface being 0. So I raised the tool head to 40ish mm above the work piece. I then single step through the program and before it hits N50 (line 23) the tool head plunges to 0.
I've dissected the G-code as best as I could, but I can't find any portion that moves the head to 0.

Start linuxcnc from the command line, read the error about the missing pin. It probably tells you the line number. Comment it out until Linuxcnc starts and review halshow to get the right spelling/pin name. This is just basic trouble shooting, not ethercat related.

linuxcnc -l 

is a very handy command (Lower case -L)

Yes, I was suggesting a totally new stepper driven Z axis/lifter assembly.

A few of us did  a lot with plasma before Plasmac burst onto the scene.

Generally, we used a touch off subroutine that was called before the M3. JohnT has a good starting example here (and some other resources)
gnipsel.com/shop/plasma/plasma.xhtml  I think I modified this to probe away until loss of contact before saving the torch height.

Cornerlock just needs to monitor the current velocity and disable the THC if it falls below a threshold (say 90%) of the feedrate. This used to be  a problem becasue Linuxcnc never saved the feedrate,   but a kind developer heard our cries and its now published in motion as motion.feed-upm and a few other variations. Here though your THC will need some kind of input that disables it.
linuxcnc.org/docs/stable/html/man/man9/m...9.html#MOTION%20PINS

I have attached a working cornerlock component

Probably start with qtdragon and customise it to suit. TTS toolng and a probe works well in it. I use it. If you premeasure tool length as Tormach does it, you don't need a tool height sensor.

Ethercat is certainly a lot easier to use today than it used to be but becasue you are interfacing linuxcnc with the ethercat master, there is some additional complexity in setting it up. But it only took  a day for me to get movement.
