Tool Change

Category: Configuration Tools

I also have an automatic tool change that already works, but I'm prompted to do so every time I change a tool and have to confirm the tool with the OK button.
I don't know how to delete it from the system. It should run automatically without the OK button.
Do you perhaps have experience with this?
Kind regards

Suggestion / request:
Overrides
When starting a program running (cycle start): user is prompted that an override (rapid, feed, or spindle) and asked whether they want to continue with override, or want to reset to 100%


I could imagine make an optional warn dialog with a settable limit. For all overrides? Feed, rapid and spindle?


Yes, something like attached.



Warning pop up if any override is on.

LinuxCNC with RIO (FPGA) SPI Issue: Unexpected 'HXHP' Response

Category: General LinuxCNC Questions

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.

7i92M very weird communication problem!!!

Category: Installing LinuxCNC

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.
