I think I have a problem with constantly upgrading during lockdowns!
With upgrading my CNC router MB to 32 bit, I bought 2 more Fysetc S6 boards to upgrade my existing OnStep and add additional functionality.
I'm selling my old STM32 controllers and SHC. $220 each posted (black and orange controllers).
- .
- 32-bit controller. I comfortably slew at 3deg/sec on my dob.
- TMC2209 UART drivers (very quiet and you can control current, steps, direction via web server rather than re-flashing)
- WiFi (smart web server), also allows remote control via planetarium software / smartphone.
- buzzer
- tracking LED
- Smart Hand Controller
- space for an additional motor (focuser/derotator)
- All boxed and working.
