Hey,
I’ve built the Primo with a kit from V1.
SKR pro + TFT35
Endstops + Z endstop.
All the latest firmware.
Mac - big sur
The machine works from the TFT screen, can’t connect the mac with Repetier-host.
I tried the default 250000 baudrate, then changed the marlin to use 115000, changed repetier as well and got same results: connection opened with “Unknown printer firmware” message, no controll on the machine from the mac.
I just gave up and bought a pi4. Installed everything (cnc.js) and it is working perfectly now.
For those who hit this page, the issue was probably repetier itself with mac (big sur). No real solution.
Btw, the image for the pi wasn’t so stable so I just installed cnc.js as instructed in their official docs. I have another pi for the 3d printer so its better this way.
