Thank you Tommy for your willingness to help—I appreciate it. However, these are different types of heads compared to industrial lasers for cutting steel. The test won't be conclusive.

Thanks for your tips.

Finally I got TMC5160 working on Octopus pro board f446 version.
I have changed the spi to spi2 with new interrupt and uart to uart3. I choosen spi2 because it's on wifi connector on board which is at the edge of board, so there will be much shorter length spi cable required and it has uart3 at same place.
Thanks a lot

Hallo Mario,

Ok, von Anfang an starten: es gibt zwei NVEM Versionen, die verschieden Mikrokontroller haben und deswegen auch verschiedene Firmware. Die Info habe ich von hier:  Remora hardware Ethernet

Eine Konfiguration Datei kannst Du selber erstellen nach Bedarf; Beispiele findest Du hier, mit der Datei nvme-basic-config.txt oder nvem-full-config.txt. Im gleichen Ordner findest Du auch noch die Datei upload_config.py; wir sprechen später nochmal darüber. Wenn Du wissen möchtest, wie die config Datei aufgebaut ist kannst Du dir diese Seite mal durchlesen.

Wie Du dir das vorstellen konntest, wird die Konfiguration mit dem Python Script upload-config.py hochgeladen. Das ist hier auch gut erklärt.

Grundsätzlich hab ich das Gefühl das Dir nur einen Link gefehlt hat, um alle Informationen zu finden!

Gruss,
Luca

Only the temporary test encoder was given 24V (directly, not via the 7i48) and then only briefly, so fingers crossed I haven't killed it.
The 3 encoders I need to use are the split output from 3x Yaskawa servopack, so physical encoder on back of servo is connected to the servopack, which provides a, /a, b, /b, c, /c outputs ("Divided encoder signals are output"). Unplugged from the 7i48, these are visible on an oscilloscope.
The single ended/differential jumpers were correctly set. 
I watched encoder.01.position, encoder.01.rawcounts, and encoder.01.counts (iirc) while the Y axis was moving and Y encoder was wired in to the 7i48; all encoder counters remain at 0.

The one thing that stands out to me on the wiring side is that there's no route for the +5V encoder supply from the 7i48, to go into the servopack. However per the attached diagram (screenshot from the servopack manual), no +5V line is shown. 

Sorry,

aber ich halte davon ziemlich wenig. Gatetreiber nimmt man dann, wenn man Gates treiben will Im Ernst. Die können hohe Ströme etc. Außerdem ziehen die nicht auf Masse sondern versorgen.

ULNs/Darlington Arrays sind perfekt für deine Anwendung. Eigentlich ebenfalls over the top. Aber schön kompakt ohne zu klein zu sein.

Ob du das jetzt fliegend verdahtests, auf Lochraster oder mittels Platine ist dir überlassen.

Btw:  Forumfrage von mir vor nem halben Jahr

pyvcp_options.hal:5: signal 'spindle-at-speed' not found
Pin missing from the hal file.
Make a new config, do not choose a VCP panel if you do not explicitly need it.

Anyone seen Ben Jordan on youtube about Flock cameras?

Oh what a bright future expects us.
CyberPunk in real life, literally !

Can i test it with a 10W LED laser?
I do not have access to laser cutter i can mess with, so i can not test it.
I would gladly test it as i did test your equipment before and i could not destroy it, on purpose, even reversing the power supply polarity did nothing! Utmost respect for that.

Hi,
ich hätte auch Fragen zum XHC und der Titel passt auch zu meiner Frage.
Ich hoffe die wurde nicht schon 1000x gestellt.
Derzeit nutze ich die .hal Vorlage aus der Linuxcnc Dokumentation.
Die Oberfläche ist CMOCCAPY
Ich würde gerne den Vorschubregel Knopf für Eilgang UND Vorschub nutzen.
Derzeit funktionieren nur die Incremente.
Wie müsste ich die Vorlage anpassen?

# Minimale/Maximale Werte für die Vorschubüberschreibung aus/in die GUI übernehmen
net pdnt.feed-override.value halui.feed-override.value whb.halui.feed-override.value # GUI-bezogene Signale für die Vorschubrate
net pdnt.feed-override.increase whb.halui.feed-override.increase halui.feed-override.increase
net pdnt.feed-override.decrease whb.halui.feed-override.decrease halui.feed-override.decrease

Besten Dank schon mal im Voraus.





 

24V ?

If the encoder has 24V outputs, that would likely damage the 7I48

Are these single ended encoders (5 wire) or differential (8 wire)?

Is the 7I48 jumpered to match the encoder type?

One way to check the encoder inputs is to disconnect them from the encoders,
set the input modes to single ended and the selectively ground the A,B and index
inputs while watching the hal a,b,and index pins with halshow. These
pins would be named something like:

hm2_7i80.0.encoder.00.input-a
hm2_7i80.0.encoder.00.input-b
hm2_7i80.0.encoder.00.input-index

 

Yes, you were right.
It was EMC problems.
I have now purchased CAT6 cables and made sure that no loops form. The error EtherCAT WARNING 0-1: Slave did not sync after 5000 ms has disappeared and I am currently having no problems with the Y-axis.

Thank you very much for the tip.

The 7i48 doesn't seem to be reading the encoders. Tried with the servo's built in ones; oscilloscope sees a/b/z pulses; tried with a cheap lbd3806 A/B enc both at 5v and at 24v - again, the scope can see a/b pulses, but nothing from the 7i48. (differential/single-ended set appropriately for each different encoder).

mesaflash readhmid shows there are encoder modules but is it weird that 'Registers:' is 0 for MuxedQCountSel?:

Module: MuxedQCount
There are 12 of MuxedQCount in configuration
Version: 4
Registers: 5
BaseAddress: 3600
ClockFrequency: 100.000 MHz
Register Stride: 256 bytes
Instance Stride: 4 bytes

Module: MuxedQCountSel
There are 1 of MuxedQCountSel in configuration
Version: 0
Registers: 0
BaseAddress: 0000
ClockFrequency: 100.000 MHz
Register Stride: 256 bytes
Instance Stride: 4 bytes

PWM is working on the 7i48 and making servos move, just no feedback.

What have I missed?

Looks like a bad bit on the PCI interface.

If the card has not been mechanically damaged, the most likely
cause would be dirty contact fingers on the 5I25 or dirty slot
contacts on the PCI slot.

As a first attempt to fix, I would clean the 5I25 contact fingers
and PCI slot contacts with 99% IPA or other contact cleaning solution.

Bonjour a tous je fonctionne depuis un moment avec la version 2.8.2 et tout okje voulais passer en version 2.9.4 mais meme si je programme tout pareil sur stepconf  la machine n'est pas commandée bien quelle le soitlorsque je test les axes sur stepconf il y un report que je vous joint si quelqu'un peut m'aider je suis preneur


 

Hi to all!

After some months without using the machine and waste some time to bring the pc running again, I got this error trying load linuxcnc.
