Hello, I am starting with laser cutting and my laser power is far from what was supposed to. And it doesnt cut with the same power in all directions and is flickering in Y direction I have Neje A40630 which it says that cuts 4mm plywood with 100mm/min, 100% power in 1 pass, but mine doesn´t cut it in 3 with air assist. ![20220107_162936](https://forum.lightburnsoftware.com/uploads/default/original/3X/4/6/469bbe694c63ede8474356aa1e2a8583c681ab80.jpeg) [1.lbrn2](https://forum.lightburnsoftware.com/uploads/short-url/oOiTMa8nRyJppTjYR45TVC3JDGh.lbrn2) (4.5 KB) I have this: controlboard: [High Quality 12V DIY Woodworking Laser Engraver Control Board Driver Controller Board for CNC Engraving Machine|Woodworking Machinery Parts| - AliExpress](https://www.aliexpress.com/item/4000093543811.html?spm=a2g0o.9042311.0.0.7b644c4ddPVKSp) laser: [NEJE A40640/A40630/N40630 CNC Laser Module Laser Head 450nm TTL For Laser Engraver Wood Cutting MDF Metal Mark Set Smarter Tool|Wood Routers| - AliExpress](https://www.aliexpress.com/item/1005002833747000.html?spm=a2g0o.9042311.0.0.7b644c4ddPVKSp) A40630 kit. thank you for answers. ---

You have to check your focus and your air assist, even if i suppose that your controller is not the best one for that module. I have the same module and this is one of my jobs with it > [@My creation with a DIY diode laser machine](https://forum.lightburnsoftware.com/t/my-creation-with-a-diy-diode-laser-machine/47637): > > This is a key holder for rooms farmhouse. 7.5mm wood done with the 50W Neje laser module at 160mm/m, 100%power, 9 pass. ---
