I just bought a 1325 size China made Metal / Non-Metal laser cutting machine, trying to cut 1 mm carbon steel with many different parameter setting - after three days still can not get a good consistent result. Below is a sample cut.
Cutting parameters:
- speed : 20 mm/s
- laser power: 60%
- corner power: 40%
- piercing delay: 1 second
- oxygen pressure: 0.6 mpa (6 bar)
- gap between nozzle to metal: 0.6mm (focus a bit below metal surface)
- material: 1mm carbon steel
Machine spec:
- working size: 130x250 cm
- laser tube: Reci W6 130W
- controller: leetro MCP6565
- height controller: Au3Tech FTC61
- laser head: Blue metal cutting head (Ruida? not sure)
As on the photo, the cut on top and top left is good but not the rest - cutting start from the bottom with lead in and lead out.
Many Youtube video showing good cutting result, i wonder why mine isn't?
