Can I integrate the CNC shield with the Raspberry to enter the satnogs network?

Hey guys!
I am starting the process of building my rotor and I would like to know if it is possible to integrate
replace the Satnogs Controller with the CNC shiel and if it works correctly with the raspberry.

Hi jp_polito,
When you ask about CNC shield, I am guessing you mean https://wiki.satnogs.org/SatNOGS_Arduino_Uno/CNC_Shield_Based_Rotator_Controller
If so, yes it is possible.
I used a shield similar to this RS485, between the Uno and the CNC shield.
I think the arduino pins used where the same as in link above except I didn’t comment out any reference to RS485 or the watchdog timer.
Also my power supply is only 13.8v not the standard 48v.
Hope this helps a little.

Thanks for answering!

Did you use the standard firmware without editing?

Thanks!

Hi Joao,
Yes I used the standard firmware, only changing pin numbers, it was easier then I thought.
I am using stepper motors with endstops. This may be harder to accomplish with a different setup.
Just checked the Arduino Uno pins I used were the same as in above link (not standard Satnogs).
Also I didn’t comment out any reference to RS485 or the watchdog timer in the firmware.
I made other slight changes to the firmware unrelated to these shields.
Also my power supply is only 13.8v not the standard 48v.
Hope this helps a little.
