Hi,
Ich habe die selben Probleme wie sonst im Forum zu lesen, die Lube.py kann nicht gefunden werden.

Ich hab den Pfad neu angeben, Lese/Schreibrechte gesetzt und es ausführbar gemacht. Dazu alles mögliche in der Datei mit Python/2/3 versucht.

Eigentlich brauche ich nur was, wo mir alle 2 Minuten für ein paar Sekunden den Ausgang öffnet, ohne Überwachung.

Kann mir da jemand helfen?

Danke
Grüße
Steffen

Your signal names don't match up.
replace

net spindle-on => timedelay.0.in

with

net spindle-enable => timedelay.0.in

the editor is buggy and messes up the formating when you edit things. Use the 'Source' button in the top left of the editor to see the tags and move them around.

Yeah, I was running a youtube video in the background but still, you're right, it's quite high.
I thought that this could be a possible cause so I've already made all of the recommended changes to the bios.
Thank you for the heads up on the core isolation, I must have misunderstood Talla83's video.
I will try to better understand kernel settings, unfortunately, there's isn't a lot of information about my dell optiplex 3020m.
Pinging the EC500 gives a latency between 0.130 and 0.25ms.

I'm trying to narrow down the possible causes, do you experience about the same ethernet latency as I do ?

EDIT: Using Halshow I can get so more debug information:

remora.read.time is between 5 to 700 000
remora.update-freq.time is between 4-700
remora.write.time is 5 to 800 000

Case is very nice, PC should be good (i have a similar looking one, works perfectly for Mesa), 5 phase steppers are nice as they vibrate less but also have less torque and yours seem to be the 5000 step per revolution ones!!! Damn, those are nice for some precise stuff. Vexta should be easy to find info on them, although lately google is failing miserably to find anything.
Power supply should do just fine, just do not expect record braking speed.

Thanks @Aciera
I've tried that but the machine does not move after that. Trying to run some gcode the spindle starts but nothing else happens.

Cheers,
Mateusz

P.S. Are the code blocks broken in the forum?

remove/comment this line in your spindle section:

net spindle-at-speed           <=  spindle.0.at-speed

Hi guys.
I'm just starting so please be gentle

I would like to add a delay for spindle to come up to speed. I'm using version 2.9.3

I have tried adding these lines:

loadrt timedelay count=1
addf timedelay.0 servo-thread
setp timedelay.0.on-delay 5
net spindle-on => timedelay.0.in
net spindle-timer <= timedelay.0.out
net spindle-timer => spindle.0.at-speed

But I get error with this text:

254: Pin 'spindle.0.at-speed' was already linked to signal 'spindle-at-speed'

The whole spindle section looks like this:

#*******************

loadrt timedelay count=1
addf timedelay.0 servo-thread
setp timedelay.0.on-delay 5
net spindle-on => timedelay.0.in
net spindle-timer <= timedelay.0.out
net spindle-timer => spindle.0.at-speed

Could anyone push me in the right direction?
Thanks.

If by workspace you mean offsets they are persistent and have to be cleared in gcode when your done using them.

Remora - Does Analog input syntax exist?

The latency is already high after such a short amount of time without running glxgears, so the latency might be the cause if it goes higher during operation. Isolating all cores makes no sense, you should always have one available for the system to run its tasks on. It won't hurt to try to find better settings in the bios and kernel parameters.
Network latency can also be a cause, pinning the Ethernet irq to the isolated core can help.

NativeCam on LinuxCNC 2.9.3

Category: NativeCAM

Hi Giovanni and others,

Didn't think it would take me an entire month to find time to try this, but that's what's happened. Giovanni, many thanks to you for your clear and thorough instructions, I have nativecam working embedded in a tab.

Linuxcnc version is 2.9.3.

Followed Giovanni's guide but had some issues/found solutions as follows:

I wanted to use Giovanni's latest edit of ncam.py as downloaded from p2 of this topic so extracted that to the Desktop and did:

> Desktop sudo cp ncam.py /usr/share/linuxcnc/gladevcp/NativeCAM
> Desktop sudo cp ncam.py /usr/lib/python3/dist-packages/

- I guess one of those is likely unnecessary but I'm not sure which, leaving them both there for now.

On my system there were already some lines pointing to gladevcp instead of aux_gladevcp, so where Giovanni's instructions say 'aux_gladevcp' I substituted just 'gladevcp'

I couldn't get the system to append the path: /usr/lib/python3/dist-packages/gladevcp to the pythonpath but it already contained: /usr/lib/python3/dist-packages, so instruction number 5 becomes this:

Move to the dist-packages directory:
> cd /usr/lib/python3/dist-packages

Create symbolic links to the files in the NativeCAM folder:
> sudo ln /usr/share/linuxcnc/gladevcp/NativeCAM/ncam.py -s
> sudo ln /usr/share/linuxcnc/gladevcp/NativeCAM/ncam.glade -s
> sudo ln /usr/share/linuxcnc/gladevcp/NativeCAM/pref_edit.py -s

(A few times I saw an error like 'ModuleNotFound: pref_edit.py' so added a symlink to that)

and a couple of other errors mostly due to me reading through a file too fast and putting a couple of things in the wrong place.

for no. 8: again, gladevcp instead of aux_gladevcp

I did not use instruction no. 9 as I don't use ncam as standalone.

Trying out first cuts using embedded nativecam last night, works as expected so far. No crashes as yet. Thanks also to BogdanTheGeek for the initial update!
