Advanced Search

just tried all that again, no luck. I did get a new message this time asking if I would like to force UEFI setup. But still failed at grub install.

QtDragon doesn't steer the oword/mdi path searches.
It does a check to see if the oword is path is valid from the info in the INI.
But even if the path isn't valid, it still passes it to linuxcnc's motion controller.

linuxcnc searches in this order:
[DISPLAY] PROGRAM_PREFIX
[RS274]SUBROUTINE_PATH
[RS274]USER_M_PATH

The 'File not open' error is from the motion controller not Qtdragon.
Maybe Qtdragon is polluting the command, but i can't know that without more information - like the debugging code I spoke about above.

As for docs...
What do you suggest I could add to this?:
linuxcnc.org/docs/devel/html/gui/qtdragon.html#sec:bridge

Disable secure boot, enable CMS, try UEFI and/or Legacy.
All in BIOS.
While at it, disable TMP if any.

It is plugged in and at that part of the setup there is no issues. Maybe I will try live and make sure.

Moved to "EtherCAT" section.

Connect it to internet.
Do ask me why, i have no clue as the Debian netinstall installs just fine without internet and so do all other versions.

I dont know what else to try. I had linuxcnc running but decided to do a fresh install to the newest. I have spent all day enabling csm, disabling csm. made a bootable usb with rufus, then tried making it one UBUNTU. No success. UEFI says grub efi amd64 package failed.  trying legacy install results in something wrong with the screen resolution and unable to read the screen so i installed a video card which fixed that problem.

legacy gives me the error grub pc package failed to install. what else can I try. B550 motherboard and ryzen 5 cpu.

I’m trying to tune my eethercat lichuan a5 servos but I’m getting around 0.02mm ferror instantly regardless the speed which then quickly drops to a couple microns steady. Can you recommend a way to fix it or is it ok as is?

I posted the question on the linuxcnc channel on the PrintNC Discord server too, and mikemacwillie pointed out the problem in my FlexiHAL-config.txt file. The Y limit input was inverted, so the machine thought it was already triggered when the carriage was nowhere near.

After changing it from True to False, I also had to revise the HOME and HOME_OFFSET parameters, as I interpreted them incorrectly.

Please, see my correct config files attached.

   

Ich arbeite gerade an eine ähnliches (aboer komplizierteres) Problem auf meine Schaublin Drehmaschine.

Als nicht programmierem habe ich mich auch von Comps gedruckt. Aber als schlechte Programmiere, mache ich es mit Unterstützung von Claude KI. Ein Comp to Komplieren is sehr einfach.

Das wichtigste ist die Aufstellung die Requirements:
Welche Ausgange gibt es, Welche sind Analog, welche digital. 
Welche Eingänge gibt es. Hat der 500W ein Spindle encoder? Getriebe positions Schalter?
Wird das Motor Open loop oder closed loop gesteuert?
Welche Inhibits braucht es? Gangwechsel lediglich beim Stillstand?
Muss der Spindle beim Gangwechel hin und her Oszillierien wie meine 400E?

Ich habe damals alles über der MAHO 400E Getriebe hier zusammengetragen.
github.com/jin-eld/mh400e-linuxcnc/wiki/...Gearbox--Description.
... dann eine Flowchart erzeugt.
github.com/jin-eld/mh400e-linuxcnc/commi...aed6b81e0642696bc8e1

Ein Freund hat es damals in zwei Durchgänge schon fertig programmiert gehabt. Mit eine ähnliche "Leistungsheft" wird KI es auch.

Das Kabel für den Encoder hab ich tatsächlich in 10 Meter. Das für den Motor mit Bremse in 10 Meter habe ich etwas gekürzt. Kann ich morgen mal nachmessen.


Edit: Das Motorkabel ist 6 Meter und die zwei Kabel für die Bremse etwas länger. 

Schade hatte gerade überlegt, ob ich den dennoch nehme, ich glaube aber nicht, dass du 10m Kabel hast für UVW + Bremse

Leadshine has two product lines. One is for the international and one is for the domestic market. EL = international, L = chinese market.

You can find the L7 on www.leisai.com. This is the chinese site.

Check the encoder resolution in the software. Mine were advertised as 24-bit and there are 23-bit. I have the L8EC drive and ACM2 motors.

Die sind noch ohne STO.

Indeed, QTdragon defaults to the linuxcnc/nc_files folder, regardless of the path set in SUBRUTINES_PATH.
Sometimes more information is needed about this, because unlike other GUIs, the path for these subroutines in QTdragon is always the same.
It would also be good to add information on how to use Bridge_HAL and how to connect these new pins to external buttons, thus expanding their use and not limiting them only to inputs that can be controlled through the HALUI pins.
In fact, no online documentation for QTdragon clearly includes this feature.
This might seem very simple to someone experienced with LNC, but from what I constantly read on the forum, there are many people, like myself, who initially don't know how to use these features.
