This is rather annoying as G28 U0 is very much not a LinuxCNC style thing.
It's valid G-code but I don't imagine very many LinuxCNC lathes are using the U and W axes.

G28 U0 W0 is a carry-over from Fanuc dialect. The U and W are not referring to U/W axes, they refer to incremental moves in X & Z.

If the control is in G90 (absolute) mode you can make an incremental move without switching to G91 by programming a "Gn Un Wn" line.

The G0 G28 U0 W0 the F360 post puts out is Fanuc for 'Go to home position, with no intermediate stops.'

Regarding G43... yes, it omits this. I've modified my post - still in progress TBH - to include a number of changes, including stealing a few ideas from the Tormach lathe post:

- INCLUDE G43 ON SAME LINE AS M6
- ADD M210/M211 AIR THROUGH TOOL
- CHANGE DEFAULT FROM G28 TO G53
- CHANGE DEFAULT RETRACT TO ONLY-Z
- ADD APPROACH SCHEME COPIED FROM TORMACH: X THEN Z

I've attached it in case anyone wants to use it. I'm not sure how successful the LCNC community will be approaching Autodesk in the hopes of getting the standard post fixed.

95% interference/shielding/grounding issue
5% brownout due to inadequate wiring in the shop and the subsequent voltage drop when plasma goes from pilot to cut
Since it was OK and lately developed this, first thing to check is shop grounding, earth dries up and does not conduct properly or at all.
-
Had the same issue a few years back at a client, i kept telling him the above, but he did reject that as reasonable so i asked him to wire machine ground to the water line as i recalled he has metal water pipes in the ground, never ever complained again.
The grounding rods are way to close to the surface if this happens to be the issue.
For the 5%, use a DVM with memory and check where does the voltage fall to when plasma triggers.
Might also be the power supply caps are drying up.
For interference, a scope would be nice, but you can use a DVM set to manual AC voltage range and measure between GND points and metal case and/or metal machine parts. If you get any reading above 5-10V, that is not OK so grounding and shielding must be corrected. Although i have seen machines with 60V still working properly, but i would not risk it, ever.

Thanks guys,
Triggers most when the following criteria are met. move to location-touch off-pierce =ERROR.
Then I can often tell it to start again and it will pierce and continue on its way. However it will ERROR after it cuts a little.
Yes triggers on pierce.
I'm cutting in the middle of the table. The joint 1 sensor is a proximity sensor that is below the left side of the table.

I used the 3D job i was working on today, set xy and z-steps to very low values, in the cam. The resulting file has 1601179 lines / 38.1 MB It took about 2 minutes to load. Then i doubled the file to 3202358 lines. 16 GB Ram and 1 GB swapfile was insufficient, Linuxcnc crashed. It seems, if there is enough memory, very large files can be loaded.

Is your /etc/ethercat.conf properly set?
Yes. Added MAC addr for enp2s0 and "generic"

check the output of these command

mill@debian:~$ sudo dkms status | grep -i ethercat
[sudo] password for mill: 
ethercat/1.6.9: added

mill@debian:~$ uname -r
6.12.86+deb13-rt-amd64

mill@debian:~$ lsmod | grep ec_
typec_ucsi             69632  1 ucsi_acpi
typec                 114688  1 typec_ucsi
roles                  16384  1 typec_ucsi
usb_common             16384  3 xhci_hcd,usbcore,typec_ucsi

mill@debian:~$ sudo modprobe ec_master
modprobe: FATAL: Module ec_master not found in directory /lib/modules/6.12.86+deb13-rt-amd64

So it looks like something didn't get installed properly despite just pasting the linuxcnc-ethercat apt stuff from GH instructions.

I am pretty sure i have used bigger than 20MB files, probably 55MB, but a bit fuzzy on that.
dmap2gcode that i use for engraving/scratching and laser, makes huge files.

Sorry for the rambling post.Since I ended up with a huge NC file when I was CAM-processing a project, I got curious—how big do NC files have to be to be considered “big” for you guys?

Das klingt doch für den ersten Schuss schonmal gut!

Das Handrad ist über den LPT-Port für den Drehencoder, und über USB als "Tastatur" verbunden.
Hat mir da vielleicht jemand einen Link auf die Doku?
Ich würde gerne QT-Dragon ( also nicht axis ) als Oberfläche verwenden, aber das sollte da ja auch klappen.

Wenn sich dein Handrad als Tastatur einbinden lässt, sollte es über die Bearbeitung von axis.py möglich sein.

Hallo zusammen!!

ich wollte mich erstmal kurz vorstellen, ich heiße Thomas, kratze am 50er und hab damals 2006-2008 eine Wabeco F1210 auf CNC umgebaut. Von damals steht noch ein alter Pentium 4 mit Win XP und Mach3 als Steuerungsrechner rum.
Dass ich den USB-Smoothstepper nicht übernehmen kann ist mir bewußt, aber mein geliebtes Handrad von Einfach-CNC würde ich sehr gerne mitnehmen.
Ich hab mal ein Bild angehängt das zeigt um welches Handrad es geht.
Ich hab in der Doku auch gefunden welche Scancodes / Tastaturbefehle gesendet werden, und auf meinem Mintrechner mit "showkey -a" auch rausgefunden dass es soweit anzukommen scheint.Nun meine Frage an die Spezialisten, meint ihr ich kann das Kandrad in der HAL-Datei mit eurer Hilfe soweit einfügen dass es wieder funktioniert?

Danke euch schonmal, Gruß, Thomas
