Switching from `pigpiod` to WiringPi resolved the issue—SPI communication is now working as expected.
Thank you very much for the detailed explanation.

I followed your instructions and used the following `gpio` commands to generate the clock:

gpio mode 7 clock
gpio clock 7 5000000

While I couldn’t measure the actual frequency, the FPGA responded properly after applying this change, so it seems that the commands produced an 18 MHz clock as you suggested.
My `board.json` already contained the following settings:

"clock": {
"osc": "18000000",
"speed": "29812000",
"pin": "35"
}

After this setup, the `rio-test` tool returned valid results, and LinuxCNC no longer shows the `"HXHP"` error.

It appears that the 5 MHz clock generated by `pigpiod` was not suitable for the ICE40, and this prevented the FPGA from functioning correctly.

Thanks again—this completely solved the problem.

I reinstalled the ethernet drivers and got it down to 12ms so got it working for now, all tho at slow speeds. I order a faster mini computer so I hope that gets fixed, I installed a 7i76u daughter card, I flashed the bin file and nothing again the CR3 led is yellow and CR6 led is red. I installed the 7i92 with 7i76 bin file.

yeah its a pin phil added in the plasmac usercommand file

Thanks for the warning. What or where is the issue with raster galvo laser support? I'm still learning about linuxcnc and the mesa hardware and understanding how to implement the relevant capabilities.

This project involves only vector laser cutting or sweeping some areas with the galvos, not raster etching of images or text etc. In the future though of course it would be good to have both vector and raster capabilities.

Dear LinuxCNC User,

I have bare minimum code of .ini and .hal file that perfectly working for single axis linear stage. Now, I want to add two switches one for emergency stop and another for feed override. I am planning to use pin 0 for emergency stop and pin 1 for feed override of Mesa 7i95 board.

Kindly provide the necessary pieces of code that need to be added in .hal and .ini file. explain the logic of the connection because I am not an expert of editing the .hal file.

The wiring I am planning for these switches are following..

either 0 or 5 volt to pin 1 using external DC power supply (I don't have switch currently but will buy it soon)

Continuous Analog voltage from 0-5 volt at pin 2 using another DC Power supply

GND, 0 volt at pin 3, because it is common ground for pin 0 and pin 1.

I am using linuxcnc 2.9.2


Thanks.

Thanks Tommy. The attached files will support the 7i97t.  I created a config successfully but I don't have a card to test with so maybe the OP or someone can give it a try and let me know if it works.  I can send in a pull request if it's good.   This will only work with 2.10 master.

After updating to latest master just copy the attached private_data.py file to /usr/lib/python3/dist-packages/pncconf/ and the pncconf.py to /usr/bin/pncconf

I would suggest making a backup copies of the original files first just in case.

Yes, Mesa can repair these cards

if they out of warranty, there is a nominal
change for chip replacement, usually $35.00

If these are not is the US, its probably cheaper
to repair locally due to shipping costs.
 

My bad. I had a brain fart. It is working in the dn, up position. I guess i lied, the thing that changed was the jumper postion. It slipped my mind i was messing with it. I guess thats what i get for messing with things late at night. I forgot i messed with it. This site is amazing. Most problems with these boards are user initiated. My question still stands; is it possible to get these boards service if something does go wrong with them? Not that i need it now but knowing the user (me) I am sure i will mess thing up at some point and need it serviced. I am just going to quit messing with things.

Maybe you can find something in this old thread www.forum.linuxcnc.org/24-hal-components...b485-to-huanyang-vfd
at least to make sure the communication works.
It was a long time ago this so I doubt I can answer any questions.

Are the axes moved by hydraulic motors or cylinders? Or, are there electric motors for the axes? Is it really an NC mill, or is that Ljumo just a digital readout?
Driving a machine with proportional hydraulic valves requires "dither" to be added to keep the valve freely floating.

I'm not to sure what you mean by the cloud ? You have to change the address to 10.10.10.10. once changed, ping the address and see do you get a response (and how long it took).

All the green led's light up

Are you saying the 4 green user LEDs all light when you start LinuxCNC?

That suggest communications are working

What does

ip a

report?

And what are the RJ45 LED states when the Ethernet is connected
and when not connected?

 The
red light just continues to blink with the jumper in the up, up position and none of the green leds
with light in the fallback mode. Ping is unreachable in up, dn and and in up, up.

Note that UP,UP is fallback at 192.168.1.121 and UP,DOWN is BootP
(DOWN,UP would normally be 10.10.10.10)

No idea if this helps KWorm, but 7i97T (not aware of 7i97S) is the same functionally as 7i92 with 7i77, probably some IO pin names are different.

Hi tommy. They are ac servos all connected to the same 240v supply. Would the tuning be done via lunuxcnc or on the servo amp? They are step and direction drives. Thanks

Have a look at carousel component included with LinuxCNC:
linuxcnc.org/docs/html/man/man9/carousel.9.html
And posts on this forum regarding it
www.google.com/search?q=carousel+site%3A...sclient=gws-wiz-serp
Also, there was similar functioning system on those small lathes, forgot their name, but there are plenty here...
