What do the Red LED Lights on the Ruida Controller Mean for Nova and Odin Lasers
Preface: This article covers what the Red LED Lights on the Ruida controller mean and some basic information about them. Just because you see a red light on, off or blinking, it does not necessarily mean that there is an issue.
Red Led Lights on Controller:
What do the Red LED Lights Each Mean:
LED1 - LmtX-
This is the X axis endstop input. This LED will be illuminated Red if the controller is receiving the X axis Endstop input. If the LED is illuminated but the laser head is not to the Left in the home position then you may have an issue with the X axis endstop.
X and Y Endstop Tests
LED2 - LmtX+
LED3- LmtY-
This is the Y axis endstop input. This LED will be illuminated Red if
the controller is receiving the Y axis Endstop input. If the LED is
illuminated but the laser head is not to the Back in the home position
then you may have an issue with the Y axis endstop.
X and Y Endstop Tests
LED4- LmtY+
LED5- LmtZ-
LED6- LmtZ+
This is the Z axis lower endstop. This LED will be illuminated Red if
the controller is receiving the Z axis lower endstop. If the LED is
illuminated but the honeycomb is not to the lower most position then you may have an issue with the Z axis lower endstop. The protection for ZLimit- only occurs if the sensor is activated while the Honeycomb is being jogged down so a stuck sensor will not prevent the bed from lowering to the mechanical limit.
Testing Z Axis Endstops
LED7- Ulmt-
Not used on the Nova and Odin series machines. Please email
support@thunderlaserusa.com if this LED is illuminated. For the Bolt Series machines, this is the AF sensor that is activated by the plunger. The LED should be on when the plunger is not pressed and then off when the plunger is pressed.
