No Laser Output/Fire

Good Morning all.

I received my Mini Gerbil and Lightburn a few days ago. Installation was a simple as a drop in and Lightburn recognized it right away. I changed and inverted my Y pins /+Homing and Laser homing and movement is 1:1 in the software.

- My Issue is I get no laser fire/power.

  • TEST FIRE works on the Power supply (Type 1)
  • Wiring from Power to MiniGerbil verified.
  • Grounding verified.

Mini Gerbil BLUE LED on for the entirety of the test fire (software) or project cut.

  • S-Value max = 1000
  • Layer Power Min/Max = 100% (Attempted Line and Fill type)

I'm unsure where to head next and would very much appreciate anyone time in assisting me.

Hi Dan,

Please send a photo of your controller connected through to the power supply.

Could you confirm which firmware version you have by typing $i [enter] into the console? If it reports serial number 12353 then you have the new firmware. In which case, type



And advise if the problem persists

If the photos look fine and the above firmware settings don't make a difference, then we'll sort you out with a replacement unit.



Hey Dan, Thank you.

The Attached picture is the wiring.

Ground checked and at first the Power Supply was not grounded. I scrapped paint and made sure all boards, laser and case is grounded.

I'm still dead in the water - no laser fire.

Would there be a better place I should utilize support? I would like to get my Laser up as soon as I can.


Hi Dan, I've emailed you to organise a replacement
