Ich habe da etwas zu meinem Entsetzen rausgefunden, es gibt verschiedene Versionen von Anleitungen.
Meine Anleitung hat Version V2.0, es gibt aber auch V1.3 und dort gibts es die 6 Ausgänge A+A-B+B-Z+Z- nicht, dort gibt es nur Z-Signal Output.
Kann ich damit auch was anfangen, ich brauche es nur für Gewindedrehen und vielleicht noch für den Vorschub beim Drehen, wäre praktischer als mit mm/min.

 

Ich habe den Verkäufer mal angeschrieben und Typenschild vom Motor und Treiber geschickt, vielleicht kann er mir sagen welche Version stimmt.

Hello, I have the same question. Where should I connect the lathe spindle encoder? And how to configure it for close loop control of the spindle? I see that rbobey1989 did a lot of test on the MPG connector, but I need to use this connector for the NVMPG. Would it be possible to point out which optoisolator ic needs to be replace by level shifter? Thanks for the input.

I would suggest to open a terminal (Ctrl + Alt + t) and start linuxcnc from the comand line:

Choose your config and check the terminal output for errors.

Hi,I have a router with 2 spindle, each spindle can be engaged to the machine by an air solenoid, I wire each solenoid to digital outputs P0, and P1, I tried to make a tool change file "toolchange.ngc" and I put it into the configuration folder...

 

and I use the REMAP as follow in the ini file:

  when I try to open LCNC it take a long time, and probet that file not open

 

how to fix this problem?

thanks

Die Jumper sind alle rechts, das passt.
Ich bin auch nochmal alles in der BDA vom Servo durchgegangen, dort steht nichts das das irgendwo konfiguriert werden kann/muss mit den Encoderausgängen.
Meine Vermutung, entweder ist der Ausgang defekt oder die haben in der Zeichnung die falschen Pins am DB44 Stecker angegeben.
Das letzte, was ich will, ist mir bloß deswegen nen neuen Servo kaufen zu müssen, ist ja nicht gerade Kleingeld.

Try:
OA+ A+
OA- A-
OB+ B+
OB- B-
Then open "show hal configuration" from "machine" menu, there on the right side choose "watch" and on the left side choose 7i92>encoder.0>encoder.0.velocity or encoder.0.raw-counts
Do this for all 6 encoders so you can see all at once and turn the spindle by hand.
Does any encoder count?

I have tried all the free encoder positions, 00 and 01 are from the glass scales and these work. Accordingly, 02 - 05 remained, all tested, no function. I really don't know what to do.
Checked the cables on the DB44 connector again to make sure they all have the right pins. Yes, that's right.

Since you seem to be loading some custom panels you may have a Python/Gtk version issue. Linuxcnc version 2.9 and up no longer supports Python2 /Gtk2 but only Python3/Gtk3.

Yeah Instantly anytime linuxcnc is run.

I also just tested locally (not headless) and the result is the same.

As well, I replaced with a new mSATA drive in my mini computer for doing the whole update....just in case i can go back to old version. Will this afftect?

upgrading from linuxcnc 2.8.4 and Gmoccapy version 3.0.91
to linuxcnc 2.9.3 and Gmoccapy version 3.4.8

Tested it today - working nice. Except it freezes few times, while putting in out parport. So maybe hardware thing / noises. On my venerable foam cutter. And of course due to lover latency its even sounds differently. Normally it runs on t61 laptop, which have nothing good on latency side. But it works .

If close and run LinuxCNC again, does it show the warning again?
If yes, most probably something with the video subsystem going over network causing delays.
Very hard to pinpoint, but try running LinuxCNC from a terminal, should have more info.

Mains filter, ferrite cores on motor wires wound once or twice, proper grounding on all power modules and drives, signal wires shilded and grounded to one side only prefferably near the inputs, all grounds wired to a single point/rail in the box, avoid ground loops, short cables - never coiled.

latency-plot is really just a different way to query the same information, and it looks great too.
The problem being that all the tools see ~4us jitter max no matter what i do but linuxcnc itself fails instantly.

I dont think headless is any problem, the previous old c2d machine was run headless too.

Gemäss Schaltplan hat dein Regler differenzielle Encoderausgänge also mal kontrollieren ob dies auf der 7i76 auch so mit dem Jumper konfiguriert hast:
 

Weiter kann es auch sein, dass du den Encoderausgang im Regler selbst noch konfigurieren / aktivieren musst.
