Mesa 5i25 config for chinese BOB

If you dont have the latest PnCConf version, it will set the PID P terms to 50
These need to be set to 1000 in the ini file for a 1 KHz servo thread

Got it.. Can't find that in the manual comes from experience..

Great Thnx....

Looks like it is comming alive to a real pro-CNC, I have backed up my setup and how to set mesa gpio to parallel etc.. ALL looks good. Anyone needs info I'll be here..

I also have a wireless renishaw probe has anyone hooked this up. Since I have it I think I'll try to hook it up for tool probe and workpiece probing..

Thank you all..

Then have you done a big step forward concrats and at sencond you can read the linuxcnc dokumentation native:)

i have to hobble from point to point but in a view years i will have it done

have a nice day and greez from austria

Hi PeterW,
I finally could make the configuration file .bit for the chinese BOB (I get only some warnings not errors from ISE).
Now I have an issue with the 6i25 mesa board when I switch on the PC if the 6i25 and the chinese board are connected together the PC won't start.
The jumper W5 is in the up position, but if the 6i25 is not connected when I switch on the PC, it will start but the 6i25 won't load my custom file and go for its default.
If I upload the custom file again the 6i25 and my CNC Router work as expected until the next time the computer is turned on.
Here I attach the custom file so you can check please if there is any error.
Thank you very much for your time and dedication.

Make sure you dont have the cable power options enabled on the 6I25, that is, make sure W1 and W2
are in the down position.

There is no reason to ever change W5 unless you are doing bridge firmware updates

If your bitfile will not load, ( and the fallback config loads instead = blinking red light )
this means the bitfile failed the CRC test either because it's corrupted or it is for the wrong FPGA

I will try to make it all over again downloading the file 5i25.zip from your site. I have chosen to modify the project ifive and my file is working perfectly, the only issue is I can't shut the PC down.

I looks like you could use the 5i25_5ABOBx2.bit file
you might try that to see if it changes your power down issue

I flashed the 6i25 with the 5i25_5ABOBx2.bit. Now when I turn on the PC the red led flashes 1 time and the PC turn off for 3-4 seconds, then my PC turns on by itself and mesa card flash 1 time again, after booting I realize that the file is been replaced again for the previous one (I lose my pin pwm)

Are you using Pathpilot? nothing can change the loaded firmware unless its a startup script like pathpilot uses if it does not like the loaded firmware...
