Ich denke die Kiste wird nie Geld verdienen. Beruflich arbeite ich auf einer CNC Fräsmaschine. Warum man dann zuhause noch so ein Teil braucht. Keinen Ahnung was ich mir damals gedacht habe. Ich besitzt eine würde sagen gut ausgestattete Werkstatt. Und da fehlt einfach noch eine cnc Fräse. 
Die 7i96s hat nicht gerade sehr viele ein/ausgänge. 
Währe daher nicht eine 7i76eu besser. Diese besetzt 48 Ein bzw Ausgänge. Hat 5 Anschlüsse für die Servomotoren. 1 Stück TTL oder Encoder Eingang. 
Dazu noch eine 7i85s um die Encoder um 4 Stück zu erweitern. So könnte ich die Encoder von den Servos an die Mesa anschließen. Oder eben alternativ die Glasmaßstäbe mit einem TTL Signal. 

In der Anleitung habe ich die Encoder Anschlüsse gefunden.
Anschluss CN1:
21 OA+ Encoder A-phase positive output
22 OA- Encoder A-phase negative output
23 OB- Encoder B phase negative output
24 OZ- Encoder Z-phase negative output
25 OB+ Encoder B-phase positive output

Die Step + Step - / Dir + Dir - Anschüsse suche ich noch immer?

Was haltet Ihr davon?
 

Danke für die Antwort. 
Die Frässpindel ist ein 3kw 400V Motor diesen möchte ich mit einem Fu ansteuern. Verbindung Fu - Mesa 24V Rechts/Links und 0-10V.
Was den Anschluss vom Servo-drives betrifft. Habe ich momentan noch keine Ahnung. Es sind Jasd Ac Servo mit 230V. Am Cn 1 Port sind gefühlt 50 Pins. 
In der Beschreibung von der Mesa 7i76Eu steht. Man kann bis zu 5 Achsen Step/Dir-Schrittmotor- oder Servoantrieben anschliesen.
Die Heidenhain Messtäbe sind LS 803 die allerdings kein TTL Signal ausgeben. Ich dacht ich habe mal wo gelesen das mit der 7i85 das funktionieren sollte?
 

Hallo, ich lese nun schon länger hier mit.
Ich besitze eine Hermle uwf die ich komplett neu aufbaue. Angefangen habe ich vor ca 4 Jahre. Nun fehlt mir noch die Steuerung.
Die Videos vom Talla83 habe ich schon fast alle gesehen.
Meine Maschine hat:
3x Servomotoren
3x Heidehnhain Glasmastäb
1x Spindelmotor mit Fu
3x Achsklemmung
3x Soft Endschalter
3x Hardware Endschalter
Hydraulischer Werkzeugspanner
1x Zentralschmierung
Automatische Getriebeschaltung
Nun möchte ich die Mesa Karten Bestellen. 
Bitte sagt mir ob meine Recherche richtig ist. 
Bestellung: Mesa 7i76EU = hat sehr viele ein und Ausgänge für meine Schalter/Taster                   
                  Mesa 7I85 oder 7i85S ? bin mir nicht sicher welche ich nehmen sollte? für Heidenhain Glasmastäbe.

Danke, Gruß Gerald

Dear everyone, i have posted about my cnc issues and am kindly asking for help here   but i think this may become harder to find then i thought. Any tips if there is consulting help or physical help and an option, please do not hesitate. I am happy to spend a dime. 

BUT i am preparing myself for a week of CNC evenings and nights as this is ultra urgent to fix for me and my small shop. 

I am using a mesa MESA 7I76EU STEP/IO STEP DIR plus I/O controller card on my CNC. its about 1.5m X 1.2m with 35cm Z axis travel distance. 
Sadly i was not able to perform the full retrofit fully myself due to time constraints. I did though the complete electronics overhaul. 
I have added a new tool length sensor and a 3d probe. 

From my cnc workflow so far i have this process in mind and I would love your take on it. I have used multiple CAD / CAM solutions in the past, the longest i have used fusion360 and right now im trying out onshape cam. 
But in general the workflow was the same:

1. CAD design the part
2. In Cam I am creating a setup
3. I create and define stock (if necessary)
4. or I set up the part reference point 
5. that defines the WCS XYZ 
6. This allows the postprocessor to generate toolpaths.
7. Using the postprocessor to output G-code
8. I load whatever CNC program (right now linux CNC QT Dragon)
9. I home the machine (if necessary) 
10. This sets G53
11. Then I either do this: 
12.  A) I insert Tool 1, measure tool 1 at the tool lenght sensor. G43 H1 mit Z20 z.b. . Then I take my tool length sensor, place it on top of the material. I am zeroing Z-height (G54 Z = new coordinate - tool length sensor dimension)) and i place the machine head roughly where i want to cut
13. I take a 3D probe, probe the stock or piece or reference that i need. I align the WCS to it. (if the probe needs calibration, i probe the table or a defined height of a pin right next to the tool length measure.) This sets G54 XYZ. Then I insert Tool 1 and measure tool length on my tool length sensor. G43 H1....
14. Run
15. Tool change
16. Measure T2 G43 H2 is stored
17. continue and repeat

BUT it seems that in our setup of linux this process does not work at all. I am getting homing error and out of probe errors the moment i am doing the basic qt dragon features for probing and sensing. 

 































 

Ordered mine Sunday. Thanks PCW. Looking forward to it's arrival.

You should be able to follow the MPG example in the  docs. It is for a parallel port but its really all the same with a Mesa card. I had no troubles with a 7i76e. You probably don't need the axis select......

You could use one of the Mesa 7i76e's not very accurate analog voltage input pins and a 10k resistor to form a voltage divider. at 25 deg C, and 24 volt field power, the voltge will be 12 volts. You might need to scale this with lincurve or a custom component. Accuracy of +- 2 degrees due to 8 bit conversion is probably OK for this application.

I have a Jianken 3.2kw spindle that has a NTC 103F3950 (10 kΩ, B=3950) thermistor and a Thermal fuse / PTC-type cutoff.
My controllers are Mesa 7i76e + 7i78 + 7i89.
How do I make use of these and connect them to my controllers.

Should be this week.
 

I decided to wait for the next batch of boards to come out. Any estimation when they will be available?

These are the limit switches I am using I believe they are connected to tb5 on the mesa 7i76e.   
And here are my latch positions and velocities   

Hi Guys,
Looking for some help getting my table back up and running. Table is homebuilt running Linux 2.8.4 with a mesa 7i76E. I had no issues for the last year and half however today i tried to cut some simple 4x4 square plates in the plasmac extras section which I've used before but it would not load the g code or file. I managed to load previous saved files that i cut before with no issues. One thing i had noticed was the system had been connected to the internet which I'm not sure how this could have happened because i never connect this system to the internet, at least i thought. After disconnecting again I cannot load anything without error messages and i noticed sheetcam will not open when linux cnc is running. I have tried searching a fix but I am afraid of making things worse. I am not very good with any of the programming or technical issues and the friend i had helping with that is no longer with us. I attached a pic of the screen with messages that came up. This is when i first open it

Hello Forum,
I have been wrestling with getting linuxcnc to run on a flask app on localhost for now.

What does that mean?
For setting the network:
forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards

 On one of my builds I used a pass through ethernet port mounted on the panel to use a small ethernet cable to connect to my 7i76e. Its hard when you have limited access but I overcame the problem with a short ethernet cable inside the box.
