Nova Series X Axis Motion Failure

Nova Series X Axis Motion Failure

Here are the reasons:

● X-axis limit switch problem

Please open upper left hand door panel, check if the wiring and roller lever of switch are well or not, like below.


YOU MAY HAVE OPTICAL ENDSTOPS, PLEASE SEE HERE IF YOUR SWITCHES DIFFER:


If they both seem to be well, please test is x-axis limit switch working properly according to the video below.


● The interface of x-axis motor have bad connection

If the x-axis limit switch is working properly, please open the laser tube cover, check if the interfaces of x-axis motor are connected well, like below.


Please power off the machine, re-connect the interface then try again.


● Motor or driver of x-axis is broken

Please open lower right hand door panel, check the x-axis driver red LED see below:




You can count the flashes of the red LED to help determine the fault:



CL1-507-3LS Driver Codes





Please power off the machine, then swap two drivers according to the video below.

MARK THE DRIVERS AND TAKE PHOTOS SO YOU WONT MIX THEM UP!


After that, power on the machine, check if the machine is resetting normally.
If x-axis still not moving at all, so the x-axis motor is broken;
If the problem shifts to y-axis, the same driver is flashing red light, so this driver is broken. 


● Driver Direction wire of x-axis is not functioning, only jogs left

The Ruida controller tells the driver when to change directions with a 0v or 5v signal. If the wire is loose, not terminated, output broken from controller etc, then the driver will only know to go one direction, the 0v direction which for the X axis is to the left.

Ruida Connector, X axis is D1:
Brown is 5v Common Signal
Blue is the Move Pulse
Yellow/Green is the Direction wire


Example Driver Connection:
(Your driver may vary but the wiring will match what is on the Ruida) Note the jumper brown wire, it is the 5V common.


Perform this Diagnostic:
-Power off the machine
-Move the X axis to the middle
-Power up the machine, but as it is booting up and attempting to home, press the ESC button multiple times to abort the homing sequence
-Use the Left and Right arrows to jog the X axis. If the axis only goes left, then you need to perform the checks below

To test the Direction Signal:
1. You can manually use a multimeter to ohm it out from the Ruida Controller to the Connector on the Driver. Check both the Yellow/Green and Brown Wires from the Ruida Connector to the Driver Connector
2. Check that the D1 Plug on the Ruida Controller is fully seated. Remove and reinsert.
3. Check that the D1 Plug on the Driver is fully seated. Remove and reinsert.
4. Check that the screw on the Direction wire and Brown is tight and is touching the metal ferrule end or not wire insulation for both the Ruida and Driver connectors
5. Retest with Diagnostic procedure above
