Important: The Test YAML Is Not for Real Machine Use

v47b-xyyza-standard-config.yaml exists to exercise the V4.7B interfaces on the bench. Its XYYZA mapping, motion values, directions, limits, spindle/laser ranges and safety behavior may not match your machine.

Do not home, cut, engrave or run a real machine with this test file unchanged.

Create a new machine-specific YAML.
Set the correct axes, steps/mm, direction, travel, speed and acceleration.
Configure limit switches, probe, homing and E-stop behavior.
Configure the real spindle, VFD, laser, relay, PWM and MOSFET functions.
Remember: the two V4.7B MOSFET channels are 1.5 A maximum per channel; heavier loads require an external relay or suitable power driver.

Safe first machine test: keep the spindle and laser disabled. Start with low speed, short moves and motors uncoupled where practical. Verify direction, limits, homing and emergency stop before real work.

Save the Test Record

Save an untouched copy of the test YAML.
Record the board revision and exact ESP32 module model.
Save the FluidNC version and complete startup log.
Record every measured voltage and any failed connector.
Take clear photos before changing the wiring.

What’s Next

If you have the matching accessories, continue to 3.1 Test RJ12 Port and 3.2 Test RS485 Output.
Then open 4 Hardware Connection for limit switches, external stepper drivers, relay, pendant, I/O expander and spindle/laser wiring.
Create and load your own machine-specific YAML before connecting the complete machine.
