Yes.
1. Stepper and CPU use separate power supplies and are optically decoupled.
2. I’ve monitored min max voltage on the CPU caps and they are fine the entire time, even during glitches.
- nicman23 1y agooptical decoupled uart?
- fxtentacle 1y agoNo UART at all: Control flow is through USB directly into the CPU, so the serial interface there is purely virtual. And then from CPU to stepper drivers it's Enable, Direction, and Step pins, all of them optically decoupled. The stepper drivers then have their own power supply and caps so that they can't interfere with the CPU power circuitry.
