"Description": "Streams per-axis stepper velocities to an ESP32 over USB serial.\n\nSends a compact \"Stp\" packet every Update carrying three signed velocities (deg/s at the motor shaft), matching the stepper channel of the FastLight firmware that drives 28BYJ-48 motors on ULN2003 boards. Shares one COM port with [WLedSerialOutput]: LED frames and motor packets interleave on the same wire.\n\nVelocities are setpoints, not move targets - each motor runs at the last commanded speed until a new packet arrives. The firmware stops all motors if packets stop for ~250ms, so a hung host or unplugged cable can't leave the stage drifting.\n\nTips:\n- Speeds are in degrees/second at the motor shaft, converted to step timing via `StepsPerRevolution` (28BYJ-48 half-step ~= 4096). The rubber-band pulley ratio is not modeled here; account for it upstream if you want knob-referenced speeds.\n- `MaxSpeed` clamps each axis (deg/s) to keep commands inside the motor's reliable range; the 28BYJ-48 stalls past roughly 50-60 deg/s at 5V.\n- Sign selects direction. Feed a SpaceMouse / slider axis through a [Remap] with a deadzone for jog-style control.\n- The op auto-reconnects (every 2s) when the cable is unplugged and replugged. Status shows on the warning-icon next to the op.\n\nAKA: stepper, motor, 28byj-48, uln2003, microscope, jog",
