2.6 Test Motor Signal LEDs

Check List · Step 6 of 12 · Verify the XYYZA EN / STP / DIR signals without motors

ℹ️

Objective: jog one software axis at a time and confirm the corresponding physical driver connector indicators respond according to the V4.7B XYYZA test mapping.

⚠️

Keep all external drivers and motors disconnected. This step checks only the controller’s signal LEDs and logic outputs.

Understand the Test Mapping

WebUI jog	Physical connector	Expected indicators
X + / −	X	X STP activity; X DIR changes
Y + / −	Y and Z	Both Y-motor groups pulse together
Z + / −	A	A connector carries Z test signals
A + / −	B	B connector carries A test signals
C connector	C	Tested separately in Step 2.7

💡 This XYYZA arrangement is a factory I/O test. It does not force your final machine to use the same mapping.

2

Open Jog and Use Safe Settings

Confirm again that no driver or motor is connected.
Open WebUI Jog.
Clear an Alarm only after confirming the bench is safe.
Select a small distance such as 1 mm and a low feed rate.

3

Jog from Top to Bottom

X

Jog X+ then X−
Watch X STP and DIR

Y

Jog Y+ then Y−
Watch both Y and Z connectors

Z

Jog Z+ then Z−
Watch the physical A connector

A

Jog A+ then A−
Watch the physical B connector

4

Confirm EN, STP and DIR

STP shows activity only while that axis is moving.
DIR changes state between positive and negative jogs.
EN remains in the state defined by the active YAML.
If an indicator is hard to see, measure that signal relative to the connector GND without shorting adjacent pins.

Expected Results

X responds at X.
Y responds at both Y and Z.
Z responds at A.
A responds at B.
The expected DIR indication reverses for each positive/negative jog.
