Hi all,

For info.
The distro is updated to use Debian 13 and linuxcnc scurve + ethercat.
There where some problems to get ethercat running on linuxcnc, these are now solved.

repository.qtpyvcp.com/repo/linux-distro/

The debian-disk.img.7z is to use directly in qemu vm.
The debian-raw.img.7z is to be copied to usb.
 

So nothing i can do against it right now? :/
 

Thanks! I will look there and see if i can get any wiser.

Edit: Look at that. Now the compensation follows work offset with those changes. Cool. Only the positive coordinates thing left then.

Ok much appreciated.
It's 2:45am I best be getting some sleep.
Guess I'll swap the eeprom.

I will be back at work in a few weeks, and i can look up the manuals for it then. These older ones can be tricky to find digitally, but sometimes one gets lucky.

I am pretty sure the drives need to be in ethercat OP state before they start to act on cia402 commands/changes.
Read/write of PDOs is only in OP state. You can read and write SDOs with "ethercat upload/download " to modify config in PREOP.
lcec and ethercat-conf.xml should bring the slaves to OP state.

Debugging tool is apart from the normal text output from linuxcnc, the system log;
"sudo dmesg" for recent messages and "journalctl" for the history.
Ethercat server puts out quite some informational, warnings and error messages there.
Debug output can be had with the "ethercat debug 1" but then the problem is to decipher that. "ethercat debug 0" resets.

Sadly not. At least so far. But i saw it in motion and for Y both axis where moving. Also when i looked behind the work envelope where the column is traveling i could see the y and x at an angle ( i assume 60° between them). You can see it even a little bit on the picture if the ATC I've posted ealier.

But concluding i dont need to switch the kinematics between Mill and Lathe. That makes things easier. Its year 1998 Integrex 200Y

Sounds like the MAC/cardname/ipaddress/netmask EEPROM has not been programmed

That is correct. The ones i have worked on are mostly newer ones and have straight X and Y axis. Do you have the manuals for it? All the geometry should be specified there. What year is it?

Building 7i92 firmware for a custom board. I've had to play around with

Turn on board everything seems ok, user leds count packets
IP set to 192.168.1.121
Responds to pings
When jumpered for bootp an ip address is received and I can ping it.

This has me stumped 7i92 mac is ff:ff:ff:ff:ff:ff

$ mesaflash --device 7i92 --addr 192.168.1.121 --verbose
Unsupported ethernet device ��������������������z at 192.168.1.121
No 7I92 board found

��������������������z bit will change on each mesaflash run

I'm guessing the data in the last packet isn't right.

 

hello,

this topic is quite complex if you dive in it.
First of all, the mentioned github repo is intended for 3d printing, so maybe thats why it works with positive coordinates, which is usual for 3d printers.

i would recommend checking out DauntlessAq fork and PR, where he corrected some issues:
github.com/scottalford75/LinuxCNC-3D-Printing/pull/8

There is description of the issues.
