Machine series support
Select the series that matches your machine.
Each series block links to its owner’s manual, quick-start guide, common fixes, and every model’s support page. One manual and guide cover the models in that series.
Desktop and mid-size CO2 laser cutters and engravers for wood, acrylic, leather, coated-metal marking, and general production work. Start with the common fixes, then open the exact model.
Laser Not Firing
Check the interlocks first, then run the simplified resistor test before assuming a failed part.
Try this first →Alignment Issues
Confirm the beam path from mirror one through the nozzle using the alignment guide and tool.
View alignment →Poor Engrave / Cut Quality
Review focus, lens condition, material settings, air assist, and bed level.

Fiber cutter support grouped by platform — model downloads, gas-setup guidance, motion checks, and cutting-quality resources for steel, stainless, aluminum, sheet, tube, and pipe.
Not Cutting Through
Verify nozzle condition, focus height, assist-gas pressure, and pierce settings for the material.
Try this first →Edge / Cut Quality
Dial in gas type and pressure, feed rate, and lens condition for clean edges.
Ask a technician →Assist Gas & Pierce
Set oxygen, nitrogen, or air and pierce timing to the metal type and thickness.

Knowledge base
Top troubleshooting topics.
Updated over time based on support volume and search behavior.
Why is my CO2 laser not firing?
Check interlocks, water protection, and the power supply first, then confirm tube behavior. Work the interlock test guide step by step, then the simplified resistor test, before contacting support.
How do I align the mirrors on my laser?
Run the beam-path checks from mirror one through the nozzle, adjusting one mirror at a time and re-testing after each adjustment. Verify focus only after the beam path is correct.
Why are my cuts dirty or inconsistent?
Review focus, optics condition, air assist, material settings, and bed level — change one variable at a time and re-test so you know which change fixed it.
