G'day everyone, 

I've just spent ages reading all 235 pages and needless to say, its inspiring and certainly my next challenge! Thank you to everyone who has contributed to this. I hope that one day i will be able to contribute in similar fashion though i'm limited now to just writing my own macros! 

I'm about to embark on this journey with an EC500. So far I have a CMSIS-DAP Link and have connected to the board. I had to jumper the Boot_Mo and 3v3 pins to get it to read correctly with the PC.

I'm trying to do a backup of the original firmware on the board before I update with Remora. I'm having difficulty using pyocd for this process unless i do it in really small chunks (which i could do then combine it later), is there a more suitable program to use to copy the existing firmware? MCUExpresso i've seen used?

Cheers

The 7I77 and 7I77D have both been replaced by the 7I77U
The 7I77U has Universal outputs (sinking, sourcing, or push-pull,
settable on a per output basis)

There is 1 (!) left in stock at Mesa from the proto run with production to follow soon.

After this make this thread I remove the card for inspection, and when I plugged it again it works fine. Somehow the pci slot develop a bad connection.

Solved for now! Thanks

The 5V connection is not required (this is just for powering stand-alone encoders)

You might try the input test I suggested (this does require single ended jumpering)

Hi,

As far as I understand, you'll need to remap a M-code (M200-M999). There are informations here  and a thread that shows an example with python here . But as you are "only" using G-code in your M-code, you don't need to use a python script; you can simply use a ngc file and remap the M-code to it. It was six month ago so I don't remember the details, but I did something similar to send a "start" signal to a galvo laser and wait a "ready" input to move to next position and start next engraving.

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?

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
