Well, some good news and some bad news. I did get all the servos moving and confirmed all the controllers work via USB connection and the DMM software (hooray!). I also got the latest versions of mesaflash, MesaCT, and got things mostly figured out for the estop configuration in linux CNC. 

Unfortunately - I also discovered that my Anything IO board appears to be bricked, so that throws a wrench in making progress for a bit. Started a thread in the appropriate section on that here: forum.linuxcnc.org/27-driver-boards/5795...done-lights-on-7i92m

Two steps forward, discover you're one step back, so it goes!

Hi,

I'm midway through converting a Brother TC215 to LinuxCNC control (I started a thread here: forum.linuxcnc.org/12-milling/57928-conv...er-tc215-to-linuxcnc ), and I've been learning a lot / things have been going well, but I've gotten to the point where I wanted to test the MESA cards in the mill and I've discovered that when I power up the MESA 7I92M board, the Init and Done lights stay red. It won't respond to ping, and doesn't show a link light via ethernet on either side of the cable.  

I saw a post from PCW ( forum.linuxcnc.org/27-driver-boards/4431...-7i96-flashing-error ) that says the Init and Done lights staying illuminated indicate corrupted flash memory. If this is the case, I'm assuming the best option is to get in touch with MESA and see about having them reflash it? Any guidance welcome. 

Also, I've got a 7I76 and a 7I77D in the mill, and now I'm concerned that if there's an issue with the 7I92M that there's a problem with those boards as well. If I power those with 5v via the appropriate terminals / jumper settings, will I be able to verify if they work via looking at the lights on the boards? 

Thanks for any help / guidance, it's really amazing to have this forum as a resource!

Yeah, you’re probably right, and I’m leaning toward LinuxCNC anyway.

Personally, I'd just buy a servo and rip oit all the crap on the spindle, you can get a 5kw spindle and drive on Alibaba for $400 shipped or less. That'll give you what you're after for a lot less hassle. Pull out the pulley system and all and just direct drive. Get a 5000rpm servo that should give you way more cut powe than you have.

The PLL fault doesn't freeze or kill the process: one drive will stop responding to cyclic position commands. The only reset function I've built into my code so far toggles cia402.x.enable and cia402.x.fault-reset, and that doesn't seem to be enough to reestablish communication with the drive.

Hi

I'd like to use LinuxCNC to simulate some lathe g-code before I run it on my actual machine. 
I have linuxCNC installed, and have the gmoccapy lathe simulations installed, but when I try to run my g-code, I get an error about "invalid character U". My physical machine has incremental axes U and W that correspond to X and Z. U and W are incremental moves, and X and Z are absolute moves. So if you're at X1.0 and you move U3.0, you'd end up at absolute X4.0, or if you're at X1.0 and move U-3.0 you'd end up at X-2.0

Does linuxCNC support incremental axes like U and W? Do I need to set them up somehow in the simulation machine's HAL file?

A google search for servo-to-go comes up pointing to alvarestech.com, that brings up the original servo-to-go main page from 20 years ago. I was real surprised to see that pop up! But, they have been out of the business since about that time. I can imagine there might be some hermit still running an STG card somewhere, but that's a stretch.  (I sold mine 20 years ago!)

I was trying to find out if the Vital Systems Motenc card is still a current product, and it seems that it is (it's been supported by LinuxCNC since 2005)

But on their web site I found that they also have EtherCAT hardware.

Okay.

Good luck and happy wiring!

I am not sure if servo2go is the same as servotogo. 

The servotogo.com address now seems to redirect to an Indonesian lottery site. 

PLL was documented not long ago. Wasn't aware it can stop linuxcnc, that's a bit excessive.
github.com/linuxcnc-ethercat/linuxcnc-et...istributed-clocks.md

This hopefully explains it better...


So per the manual, I have the following control commands: Pin 7 / Pin 8 (Analog in) connected to a Mesa analog output, and jumpered for 0-10V. This is the main control. The VFD doesn't get on/ off commands, it gets speed commands. Pin 9 (Power for a control poti) Unused. Pin 62 (Analog out) Unused Pin 20 (power out for digital inputs) Unused. Pin 28. (Activate VFD) Controlled by Mesa digital output.Pin E4 (Change direction) Controlled by a Mesa digital output.
Pin E3 DC (DC braking) unused.
Pin E2 (Jog at frequency 2) Unused.Pin E1 (Jog at frequency 1) Unused.
Pin 39 (Gnd) Connected. Output Relay
K11 (NO Out) Connected to Mesa inK12 (Common) Connected to Mesa in.

Servo2Go seems to still exist, but I don't see anything like the original Servo2Go ISA bus interface card on their web page.

Having mostly put the machine together and found ModbusTCP unsuitable, I took another attempt at Ethercat.

1. I installed LinuxCNC 2.9.4 from the ISO on the nearest available beige box (which has a Realtek ethernet card)
2. I installed the r8168-dkms driver
3. I built ethercat from source to exclude EoE as follows:
   1. git clone gitlab.com/etherlab.org/ethercat.git ethercat-master
   2. cd ethercat-master/
   3. git checkout stable-1.6
   4. ./bootstrap (I didn't have autoconf or libtool installed: they are necessary)
   5. ./configure --sysconfdir=/etc/ --disable-8139too --enable-userlib --enable-generic --disable-eoe
   6. make all modules
   7. sudo su
   8. make modules_install install
   9. depmod
   10. exit
   11. sudo nano /etc/ethercat.conf
   12. sudo systemctl enable ethercat.service
   13. sudo systemctl start ethercat.service
   14. sudo systemctl status ethercat.service
   15. sudo chmod 666 /dev/EtherCAT0
   16. sudo nano /etc/udev/rules.d/99-ethercat.rules
   17. sudo udevadm control --reload-rules
4. I installed linuxcnc-ethercat from the repository
5. I installed the CIA402 module:
   1. git clone github.com/dbraun1981/hal-cia402
   2. sudo halcompile --install cia402.comp

And it works very nicely most of the time. See attached ethercat xml file.

I see some "PLL error" failures sometimes, which can only be "solved" by restarting the control process. I've tried adjusting refClockSyncCycles and sync0Shift in accordance with some other threads, but I don't understand what those do or what they should actually be.
