I've finally started on a conversion from Anilam 1400 to LinuxCNC. I believe this is an Eagle 200, the mill itself completely lacks any plates or other information. I've decided to place the electronics on a wall behind the mill.

File Attachment:


I've mounted a 7i92 and 7i77 on an aluminum plate ready to go on the wall.

File Attachment:


I've tested the servos with a dead AAA and they move just fine. But now the fun begins. I've never worked with Mesa boards and have questions. From what I see I can power the 7i92 from the 7i77. And that requires at least a 5 volt supply on TB1. And in my case I do want to leave it 'back powering' the 7i92. These are questions :) Field power, I'm not sure I understand as every thing but the analog out can and will work with 5 volt levels. The position encoders are 5 volts.

I have installed the front page version of LinuxCNC on a PC. Is that the right version for the 7i92? Also, from what I understand, this is a Plain Jane setup. 5 volt positioning inputs and a single ended +=10 servo single. So I'm guessing the .bit file I need is off the shelf.

I've never worked with machine like this so it is all new to me.

Thanks, Dan.

You can back-power the 7I92 from the 7I77 5V as long as the 7I92 and 7I77 are jumpered to use cable 5V

(7I92 W4 UP, 7I77 W5 LEFT)

This works because the 7I92 only needs a few 100 mA of 5V power

Ethernet cards need LinuxCNC Uspace. The Documents show how to install the Debian version. I sell a pre-loaded with Linux Mint with LinuxCNC Uspace loaded.

Hi,
Yes, I learned I needed the uspace version. I'm booting from 3.4-9-rtai-686-pae.
And:
dan@debian:~$ uname -v
#1 SMP PREEMPT Debian 3.4.55-4linuxcnc

I followed all the instructions here: Installing on Debian Wheezy (with Preempt-RT kernel)
I've set the network card to manual, the Ethernet lights on both the computer and the 7i92 are flashing away. But when I try to ping...

BIG UPDATE!


I looked at the LEDs blinking and it was just not right. I pulled this cable I had marked 'crossover' from a box and assumed. I took a good look at the colors, sure enough, they where not right. I cut the crossover end off and re-crimped it. Now I can ping the 7i92. Now I will try to mesaflash. I'm assuming, (I do a lot of that assuming stuff.), that the 7i22X2 is fine for one 7i22 board. I'm off to work on this... I'm at:
dan@debian:~$ mesaflash --device 7i92 --write 7i92_7i77x2.bit --addr 192.168.1.121
Can't find file 7i92_7i77x2.bit

You must power cycle board or use --reload command to load updated firmware.

The 7I92 does not require a crossover cable (it will work but its not required)
any standard CAT5 cable will work

For a 7I77 daughter card you will want to use 7i92_7i77x2D.bit
This is in the 7I92.zip support file from Mesa

I'm booting from 3.4-9-rtai-686-pae.


This is an RTAI kernel, not a Preempt-RT kernel so will not work with hm2_eth

The kernel name should have SMP PREEMPT RT in it
(note the "RT")

Something like:

4.9.6-rt4 #1 SMP PREEMPT RT Wed Feb 1 07:42:19 PST 2017 i686 i686 i686 GNU/Linux

OK, I'm up to here. I have the servo flashed, I'm just not sure about the PWM pins, are they not labeled? I'll post below. But I can get all the way to here now:

There are no PWM pins, you must have started with a hal file for different hardware

I would suggest starting with a pncconf created 5i25/7i77 config,
replacing every instance of "5i25" with "7i92"
"hm2_pci" with "hm2_eth" any patching the config line by adding the ip address token

I found a hm2-servo7i77.hal that looked good and just pointed from 7i92.ini. I got way farther, just:
Note: Using POSIX realtime
HAL: ERROR: function 'hm2_7i92.0.pet_watchdog' not found
./hm2-servo7i77.hal:64: addf failed

I won't need that to test the DRO pins, that would be next. But I'd guess it is real important when I start applying power to the servos. I also had to comment:
net home-switch <= hm2_[HOSTMOT2](BOARD).0.7i77.0.0.input-00
net home-switch => axis.0.home-sw-in
net home-switch => axis.1.home-sw-in
net home-switch => axis.2.home-sw-in

But then, my machine has no homing switches yet anyway.

linuxcnc is up and running now!!!! Thanks.

But I'm still unclear how the servo drive works without PWM outputs??

Best, Dan.

7i77 has 6 analog outputs, not PWM, meaning the 7i77 can produce analog voltage ranging from -10 V to +10 V. It most probably uses high resolution DAC ( digital to analog converters ) for that.
As usual PCW, feel free to correct me if i am wrong. I am still learning the inner functiong of mesa cards, hands on experience only for the last 2 months.

Tom

Hi Tom,
Thanks, I was figuring something like that. I'm two months behind you. :) I did read your whole thread, it was helpful. I'm getting the idea that the Mesa system is very well thought out. It is just that every application is different, so we have to roll our own.
