RaspberryPi 4/5 Ethercat Rtelligent ECT60 Synchronization error

Category: EtherCAT

I think it is something the Rpi does at regular intervals, drops the network interface for some reason.
Inspired by some googling can you search through the syslog to see if you find why eth0 is reset?
sudo journalctl -b | grep eth0

Edit. Another idea is to configure NO ip address on the interface.
Maybe it can prevent the os from doing ip-related things to the interface.

I've tried POSITION_FILE, but it can only save the position when linuxcnc is closed normally. When my PC is suddenly turned off, such as due to a power outage or linuxcnc error, POSITION_FILE doesn't save the last position of the machine movement.

Dual X Axis Control

Category: General LinuxCNC Questions

Hello all,
I am consulting for a company that has a 2005 Onsurd 3 axis. It has an AMC-B that is going out. We are looking at retrofit options, and LinuxCNC appears to be at least heading in the right direction. With LinuxCNC, would it be able to do the following?

-Control 2 X axis for two tables that may run independent, together, or alternating
The CNC operator provided this description for this functionally as it currently is: "In the machine programming, there is a miscellaneous parameters that you go into on the keypad and at that point, it’ll ask you Table type and you type one and then hit the inner button if you want Table one only or two and enter that if you only want table 2 only or three and that if you want the two tables linked together or four and enter there and that’ll give you the alternating tables and then you can assign a job to each table. "

-Control a servo to align the 12 tool changer
-Sequence I/O to process the tool change

Can someone provide insight on this?

Thanks!

It says LinuxCNC post processor but it does output line numbers with N, why?
Mach3 uses line numbers, not LinuxCNC, so try removing them.

I still have the error “unknown word where unary operation could be” even when I output a .ngc file from SheetCam. I've test with the LinuxCNC plasma post processor for SheetCam. In Monokrom I am using the plasma_gcode_preprocessor (default with Monokorm). I have attached the pre processor log. There everything seems to work. However the LinuxCNC parser seems to be unable to read whatever the plasma_gcode_preprocessor puts out. The error comes from here: github.com/LinuxCNC/linuxcnc/blob/af15a4...interp_read.cc#L1424

Preprocessor log:

I would measure the voltage between OUT0+ and OUT- when on to diagnose the issue.

it should  be much less than a volt

If OUT5 is used instead (this is suggested for Plasma systems) the voltage may be higher
but no more than 1 volt or so.

I tried this ethtool --set-eee eth0 eee off but it did not help at all. No I have tested two independent setups and inserting ethernet switch between Rpi and ETT60n solved the issue. In rpi5 there is no l --set-eee eth0 eee available but same issue when using without switch.

You can use any unassigned GPIO pin  as an input so limit/home switches are supported

Optocoupled step drive wiring:

Sinking:

DRIVE DIR+ --> +5V
CONTROLLER DIR- --> DRIVE DIR-

Sourcing:

Drive DIR- --> GND
CONTROLLER DIR+ DRIVE DIR +

Most step drives have optocouplers built in

BUT the 7I92T is really not intended for direct connection to field wiring.

It will work but a single mistake with grounding can easily damage the 7I92T.
The 7I92T was really designed as a parallel port equivalent device with added features
and is intended to work with parallel port (or Mesa) breakout boards.

Mesa 7i96s Torch on and arc ok problems?

Category: Plasma & Laser

Hi everyone,I’m finishing up my CNC plasma build using a Mesa 7i96s, Spartus ProCut 45PCF, and a THCAD-5 (not yet connected).My issue:
The torch on output (OUT0) from the Mesa won’t trigger the plasma directly.
If I short pin 3 & 4 on the Spartus CNC port manually, the torch fires instantly.
When I run the signal through a relay, it also works fine.
But when I connect the Spartus directly to OUT0+ and OUT0-, (or OUT5) nothing happens — even though the Mesa output LED lights up and I can measure switching.The Arc OK behaves similarly — it only works through a relay. But when i have torch pulse on it stays active. And when cutting a circle is just flashes real quick and torch dies. 
The output LEDs on the Mesa board are about half as bright as the input LEDs.All 0 V lines in my control cabinet go to a common terminal, which is also tied to PE (earth) and the machine frame.
I have 24 V on IN COMMON, and everything else seems correct.Has anyone successfully triggered a Spartus ProCut 45PCF directly from a Mesa 7i96s output (without a relay)?
If so, could you share how you wired OUT0+ / OUT0- relative to the plasma CNC port pins (3–4)?I’ve looked through other wiring diagrams and posts, but haven’t found a clear answer yet.
Any suggestions or example diagrams would be very much appreciated. I will try and make a diagram of mine so you guys can have a look :))Thanks!

Does this firmware version also contain pins for ‘End Stop’ for 4 axes?

Does this mean that I have to use optocouplers?
What does ‘a sinking configuration’ mean?

Please tell me, can I use encoders from the Mitutoyo AT111-100F або AT111-200S series?
