ARE YOU KIDDING ME YOUTUBE !!!

Category: Off Topic and Test Posts

  The really sad part is that other countries will look at it as a template for how to do things. I have noticed
how little value most governments seem to place on their citizens. Oh they will say one thing, but what
they do is what truly matters. Just another example of George Orwell's AnimalFarm 
"All animals are equal, but some animals are more equal than others"

But what do I know.

Mesa 7i96 step ausgangsignal =5V , Schrittmotortriber eingang 12V was nun?

Category: Deutsch

Danke für eure Nachrichten und Vorschläge,
hab soeben Nachricht von meinem Kumpel bekommen:
„selber bauen mach mehr Freude :-)
Ok ich wollte nur mit meinen begrenzen Kenntnissen helfen,
bin da wo etwas zu schnell und zu weit vorgeprescht!

Bis hin wurde Schritt- und Richtungs-Signal vom Parallel Port, via selbstgebauter Karte, an die Motortreiberkarten geleitet.
Wir werden diese Schaltung übernehmen, da der Parallelport mindestens 5V ausgegeben hat.
BILD

Unschwer zu erkennen unten der Parallel Port, Rechts Analog 0-10V, per Relais Spindel ein und darüber die Referenzschalter.
Links die Anschlüsse für Takt und Richtung.

Ich werde unsere Lösung sobald sie verbaut und getestet ist hochladen. (Wenn ich darf!?)

Danke nochmals an alle Meldungen zu diesem Thema!

Kuhlmann Engraver/mill retrofit Build log

So it has been slightly more than 2 weeks, more like five or six because of reasons. But I have managed to make some progress over the holidays. The first step was obviously to clean up the entire machine, it might not have seen any serious use in a long time, if ever, but it was still in need of a serious cleaning.I started by removing all the cables and electrical parts from the machine since basically all of those will be replaced anyway.It turned into a neat little pile



After that I started cleaning the machine and even though I hadn’t really planned it I also pulled apart like 90% of the mechanics and cleaned all the parts individually.This was really necessary as I hadn’t been able to get all the plastic chips and old grease of any other way.



This included pulling apart, cleaning and re-greasing both the needle bearings for the ballscrews and the linear carriages.  As far as I can tell all this hardware is still available, the bearings  and what not, so it shouldn’t be an issue to service it if any parts give out in the future. 





Just look at that before and after. Some of the balls didn’t circulate at all since the traces were so full of hardened grease, depending on the loading direction. I got all of them running again after first wiping them down with break-clean and then flushing them with penetrating oil to loosen and rinse out all the grease.I didn’t remove any of the supported rails so hopefully I haven’t caused any alignment issue. We’ll see when everything is back together, I will do a proper alignment check then. 



It cleaned up real nice so I take that as a confirmation that this is a fairly low-hours machineIt’s mostly back together again and I think the next step is to work on the motor mounts. To that end I took a bunch of measurements when I had it apart to be able to manufacture some adapter plates, I will start to just 3D print them and when I have a design I like i’ll cut them on my old CNC router. It hasn't been used in a while so that will be nice. 



I also have the main layout of the electrical system finished, I just have some details left as well as doing the schematics, I am planning on doing a full set of schematics for this machine, I have been wanting to try QElectro tech and I think this is a nice project for that.Cheers

The arc interpolations need some work, G1 seems pretty good, will work on arcs next, maybe not ready for testing yet...

I'm trying to figure out how to configure delta a2-e. I did as described in this thread, and the ethercat slave command returns:
0   0:0   PREOP        ASDA-A2-E
But I still get an error and don't understand what to do. Any help would be appreciated.

The 3 axes Exe board which I have needs only 5V supplied by the MESA.. Simple connection.- signal output as required by the MESA.

Bitfile or help – Mesa 6i25 + 7i74 (BiSS-C) + 8i20 + 7i70/7i87

Category: Driver Boards

Ok so i progressed a bit But my raik060( biss-c/ssi signal) need a master clock in order to operate

(BiSS-C / SSI):  DESCRIPTION:                           WIRE
VCC                 Power supply input Power         Red
MA+ / CLK+    Positive clock input                  Orange
MA- / CLK-         Negative clock input              Yellow
SLO- / DATA-     Negative data output             White
SLO+ / DATA+  Positive data output               Green
GND                  Ground Power                        Black
 
and i get some contradictory information. i read somewhere that only a 7i85 card could generate a clock and not other card like 7i76 or 7i74 ? if it is true that mean i have to rethink ma configuration.

For now i have added this to my main hal and it seams to be good, at least it don't crash :)

For whomever would like to help me test the improvements, download and build, this is not in master yet, still waiting for the halcsope to get merged, I have only tested on the scope so far, will do some testing on real hardware before sending a PR to master.
Would love to have some help testing, thank you all!

still in fixing a few things, don't expect the git history to stay

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

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

7i77D availability

Category: General LinuxCNC Questions

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)
