Homemade CNC Plasma - hypertherm, Mesa, gear drives, nema 34.

Category: Show Your Stuff

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.

Ethercat installation from repositories - how to step by step

[Forum/internet is being really unresponsive, bear with me]

Thanks gents for having a look.  Here's the terminal outputs:

You need to use sudo for systemctl and journalctl. Can you redo and share?
Warning: Spoiler!


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?

Wechsel Mach3 auf Linux CNC bestehendes Handrad weiterverwendbar

Category: Deutsch

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.

Gruß, Thomas

Ethercat installation from repositories - how to step by step

Category: EtherCAT

check the output of these command

systemctl status ethercat.service
sudo journalctl -xeu ethercat.service --no-pager
dkms status | grep -i ethercat        # module built for running kernel?
uname -r                              # running kernel matches?
lsmod | grep ec_                     # loaded?
sudo modprobe ec_master              # manual load - shows real error

Wechsel Mach3 auf Linux CNC bestehendes Handrad weiterverwendbar

Category: Deutsch

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

Wechsel Mach3 auf Linux CNC bestehendes Handrad weiterverwendbar

Category: Deutsch

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

from what I understand, that would likely run but the screen preview might have a big spasm!

I've never seen the sysv error before. 
Odd others have got the new method working already.

New builder hardware suggestions

Wow that just got expensive. This is a portable table, the cut dimensions are adjustable at the design stage and I am probably going to make mine 1000x800. The designer suggested a Nema 23 stepper kit with DM542 drivers and a Mach 3 controller from Aliexpress at about $235. I was hoping to use something like this probably with just a different break out board. Is this not possible? This is for hobby use and I am in QLD Australia if that makes any difference. This is also my first build, hopefully learn something and able to modify or make a MK2 at some stage.

I'm also  in Queensland also (Brisbane). You can find my email address on my @MrRodW YouTube channel. You can use a parallel port breakout board.I bought 2 off Amazon for $20. I might have a THCAD which you can use with the encoder component to read torch voltage for THC. If you went with Mach3, you'd probably need to get a Proma THC or similar so it will get expensive quick too. The DM542's should be fine. Very hard to kill. Geckos are way overrated.
