MIRA - my laser tube does not fire

Modified on Thu, 19 May 2022 at 12:36 PM

We need to check a couple things to determine what could be the cause of your laser tube not firing.
IF SENDING ME VIDEO(S) TO ANY OF THE BELOW ITEMS, MAKE SURE THE VIDEO(S) ARE UNDER 20MB each.

1. Please visually look over your tube for any cracks or damages.

2. WITH POWER OFF TO THE MACHINE FOR ATLEAST 15 MINUTES AND THE LASER UNPLUGGED FROM THE WALL, please check (inside the left side of your machine) that this cable connector is still screwed together properly (white barrel connector):

3. WITH POWER OFF TO THE MACHINE FOR ATLEAST 15 MINUTES AND THE LASER UNPLUGGED FROM THE WALL, please take the red cap end off the left side of your laser tube and send me a picture. Make sure the red wire is situated properly and not loose and that the black electrical tape is intact:

4. WITH POWER OFF TO THE MACHINE FOR ATLEAST 15 MINUTES AND THE LASER UNPLUGGED FROM THE WALL, please check the right side of the laser tube and make sure that the white wire connected to the laser tube is not loose and that the black electrical tape is intact. Please send me a picture of this:

5. WITH POWER OFF TO THE MACHINE FOR ATLEAST 15 MINUTES AND THE LASER UNPLUGGED FROM THE WALL, insure both green coloured connectors are pushed into the laser power supply and that all wires are properly seated and not loose in these connectors:

6. Next, please check the L-0N1 wire to Ruida control board is properly seated in the connector and not loose (this wire is what controls the "pulse" to your laser tube). This board is inside the right panel of your Mira:

7. With power on to the laser, test the laser tube pulse at the mirror #1 housing by putting tape on the housing and doing a quick "pulse" of the laser to make sure it burns a spot on the tape:

8. While running a laser program on your Mira, video this end of your laser tube while it should be pulsing:

9. Please press the laser power supply TEST button on the power supply - check if it pulses the laser tube (this button is in between the green connectors on the power supply). Video the laser tube at the firing end to see if this button fires the tube:

10. Also video the screen on the laser power supply to see if the red coloured digital display changes at all when the laser is pulsed (if the power supply has a digital screen on the top of the unit):
