Hmm. Could some one point me how to configue dual corexy ? For each side separate axis.

Plasma and Ethercat?

Category: Plasma & Laser

Hey Guys,

I have retrofitted a lathe and two Bridgeport Interact Mills using Mesa 7i76e's.  I am happy with the 7i76e and pncconf but due to their availability (or lack thereof) I am considering doing my new 'from-scratch' plasma table build using an Ethercat interface. 

My question is this: If I go down the Ethercat path will I be able to re-use all of the good work that has been done in the plasma area or will I be doing custom builds?  More specifically can I set up a plasma system using Ethercat by modifying .ini and .cfg files?  I am willing to recompile some fork of the main line of development but I don't really want to be on the 'bleeding edge' of the development effort.

Thanks in advance and Happy Thanksgiving!

JH

Are the glass scales differential out or single ended?

The 7I76 encoder input needs to be jumpered to match the encoder type

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.


Nur ein Indexsignal wird leider nicht reichen.

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.

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

Choose your config and check the terminal output for errors.

Then, the Linux CNC Configuration Selector appears, on the left hand side, when I click all the showed ini files, the right hand side shows "No details available". Obviously, it didn't refer to mine one ? The path location of my ini. and other files are : /home/my_user_name/linuxcnc/config/my_LinuxCNC_machine. Are there something wrong?

Can you try all encoder inputs with with one glass scale output?

Note that encoders are:

00  7I85 ENC0
01  7I85 ENC1
02  7I85 ENC2
03  7I85 ENC3
04  7I76 ENC
05  Aliased 7I76 (dont use)

Also you can debug with just a voltmeter across the A,/A B,/B pins
you can also check the input pins with halshow:

hm2_7i92.0.encoder.00.input-a
hm2_7i92.0.encoder.00.input-b
hm2_7i92.0.encoder.01.input-a
hm2_7i92.0.encoder.01.input-b

etc


I have now simply plugged the connector from the glass scale X (00 7I85 ENC0) into the encoder input of the 7i96 (04). When the X-axis moves, the yellow LED at A changes constantly between on and off, B remains on, Count changes between 0 and -1 during the movement, Velocity shows a value from time to time during the movement. I did not change anything on the HAL for the test.
Measured with the voltmeter at the outputs of the spindle encoder, there is no value, so A+ is measured with A- etc.
all this in the unplugged state. When the plug is plugged into the 7i76, I have values of 228 ohms.

I think I did the stupid thing that I copied old LinuxCNC startup icon from the old computer screen and paste to new one, I haven't create a new one instead. Let me check all the things first

Gmoccapy Toollength sensor routine stops sometimes was created by pe8art

Gmoccapy Toollength sensor routine stops sometimes

Category: General LinuxCNC Questions

Dear All.

I use Gmoccapy for my CNC-Router.
I use the macro below to measure my tool height.  
Switching between tools it for some tools stops in the middle of traveling to the probe.
For others it doesn't, does anyone have an idea?

Best regards from The Netherlands.

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.

Remora - Does Analog input syntax exist?

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.

REMAP M6 problem

Category: General LinuxCNC Questions

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.
