I'm not sure if you were asking me to upload a video to YouTube showing what is happening - but that's what I did. The video link is here:

It's very hard to 'see' or hear - but as part of the homing function, the axis slowly approaches the limit switch, then moves away, then back and finally 'jumps' away from the switch.

I tried changing the MAX_ACCELERATION setting in the .INI - in both the AXIS_X and JOINT_0 sections. I halved them but it made no difference. I also attempted to move the sliders at the bottom of the LinuxCNC screen (below the jog section) way down one at a time - but that made now changes.

If I try to run even a simple shape (gcode for a small rectangle) it just 'locks up' like you see in the video when I attempt to press the 'SHIFT-(any arrow).

I'm just buffalo'd - I cannot figure it out.

Hi All,

I am in the process of converting our workshop homebuilt plasma table from MACH3 to LinuxCNC.
So far all the basic things work except for the plasma torch timing. The particular torch & inverter we have
needs a minimum of 15 second delay from the end of one cut to the start of the next. In MACH3 we have a
M3 macro that takes care of that. Is there a feature in QtPlasmaC / plasmac that can do something similar.?
I can do it using the retry logic - but that usually wastes a lot of time between cuts.

Scott.

The expansion board is "plan to sell it" but the prototypes is in making, so its need more time.

Well, you were right. I had to use the modified parameters in the DH method.

What version of linuxcnc are you using?
Can you post your config files?

Nein, bei der Y achse ist die HOME_SEARCH_VELOCITY negativ:

Das Problem mit den Limiten wird aber erst sichtbar werden, wenn die Achsen erfolgreich referenziert sind.
Für das eigenliche Referenzieren ist wichtig, dass 'joint.n.home-sw-in' False ist wenn der Referenzschalter nicht aktiviert ist.

Verstehe ich nicht bei der Y Achse habe ich die selben Einstellungen

Deine Einstellungen widersprechen sich.


bedeuten, dass der Referenzschalter am positiven Ende der X Achse angebracht ist.

Wenn das so ist dann müssten aber

When I open the axis sim the units are inch, when I open the axis_mm sim the units are mm.

In the [TRAJ] section of axis the LINEAR_UNITS are inch and in the axis_mm the LINEAR_UNITS are mm.

I was able to get the spindle torque figured out. This is how I did it:

loadrt scale names=spindle_load_scale,spindle_rpm_scale
setp spindle_load_scale.gain 10
setp spindle_load_scale.offset 0
net spindle-torque nyx.0.servo-05.trq-fb => spindle_load_scale.in
net spindle-load spindle_load_scale.out => qtpyvcp.spindle-load-indicator.in-f
setp qtpyvcp.spindle-load-indicator.max-val 150
setp qtpyvcp.spindle-load-indicator.min-val 0

HalloIch habe eine Problem mit  der Referenzierung meiner X Achse.Z und Y fahren richtig , die X-Achse fährt auf den Schalter bleibt kurz stehen und fährt dann in die selbe Richtung.   Egal ob die Vorzeichen bei Home_latch_vel   in minus oder plus mache . Wenn ich Manuel  in die richtige Richtung fahre  ich ins Minus.Anbei meine Einstellungen in der ini.

Hello, friend. First of all, congratulations on successfully using NVEM V5 on linuxcnc.
I have the same control card as yours, but I read scotta's reply and read the 230 pages, but still can't find a solution, and I don't see a complete process. Can I ask for your help?

Hello scotta, you are such a great programmer.
These days, my NVEM V5 RT1052 control card cannot connect to Mach3, and then I found your post on building linuxcnc on Google. The post shows how to flash Remora firmware on NVEM V2. I spent two days reading the entire post of 230 pages.
But since this is not my specialty, it took me two days to install debian12 linuxcnc.
I also want to revive my NVEM V5. I want to embrace linuxcnc and abandon Mach3. I need your help. I now have two ST-LINK V2, exactly the same. I changed how to flash Remora in the first step. After the V2 soldering pins are connected to ST-LINK, the control card does not light up the signal light as you showed on YouTube. It must be connected to 24V power supply.
I found that many people mentioned this problem in the 230-page reply. I hope to get your help. I want to record the whole process as detailed as possible and then show it to those who need it.

1) Reviewed 2009 Debian documentation which suggested $ dpkg-reconfigure locales.
Along the way found instruction to use the Spacebar to select a locale from the list offered.
This is missing from the menu-config instructions.
When locale is selected with Spacebar, the missing step in previous post appears.
Tried it the sequence, and failed to set locale.

2) Reviewed a June 2023 suggestion from www.server-world, suggesting $ localectl.
Ran the sequence and failed.

3) Debian Wiki from 2022, section labelled "Manually".
$ sudo nano /etc/locale.gen
Long list of locales, all commented out.
Uncomment en_AU.UTF-8 UTF-8
$ sudo locale-gen
Locales are generated.
$ locale -a
C
C.utf8
POSIX
en_AU.utf-8

LogOut/In.

$ locale
Full suite of en_AU.
SO SUCCESS.

Ran PnCconf again.
SUCCESS.

I don't know if the LogOut/In step is listed in the official LC 2.9.4 instructions.
If so, I missed it.

Prospect for cutting metal with LC 2.9.4 looking good.
John.

sorry for useless comment, but great job Atrex! 

do you have pcb files for that expansion board or you plan to sell it?
