Bad cut?
Send a photo of it.

Dross that will not come off, a rough lower edge, a part that stays welded into the sheet — 47 documented defect modes with the cause and the exact parameter to change. Works on any fiber laser, whoever built it.

  1. 01 Photo
  2. 02 Cause
  3. 03 Fix

You do not need to know why it happens. Photograph the edge and the assistant names the cause and the one parameter to change.

01

Photograph the edge

One phone shot of the cut face. No lighting rig, no macro lens — the workshop photo you would send a colleague.

02

Answer three questions

Material, thickness, assist gas. If you do not know the power, the assistant asks — it needs it, because 3 kW and 12 kW fail differently.

03

Get the parameter to change

Not «check everything» — a ranked list of likely causes with the specific correction: gas pressure by 0.1 bar, speed by 5%, focus by 0.5 mm.

Defects it recognises

Every entry carries a reference photo, the cause and a step-by-step correction — scoped by gas, material and thickness, because the same dross means different things on 2 mm and on 20 mm.

Hard metallic dross
welded to the bottom edge, needs a grinder
Brittle dross
comes off with a scraper
Long thick dross
hanging beads along the whole edge
Needle-like fine dross
sharp, thin, hard to feel until you touch it
Non-cut / unseparated edge
the part stays in the sheet
Edge burnout
blowout and overburn on corners
Edge taper
the kerf is not square to the surface
Bottom edge melting
rounded, re-solidified lower edge
Bottom edge roughness
coarse striations low on the face
Severe striation curl
waves running off the vertical
Matte edge
dull instead of bright — usually gas or purity
Plasma formation
the cut goes unstable and loud
Beam reflection on copper and brass
cut interruption on reflective metals
Mill scale defects
rusty or scaled plate ruining an otherwise good setup

Cutting parameter tables

1,500+ validated cutting and piercing parameters by material, thickness, assist gas and source power — carbon steel, stainless, aluminium, brass, copper, galvanised, from 1 kW to 20 kW. Separate tables for engraving, welding and cleaning.

Free on every plan, including the free one.

Error and alarm codes

Type the code or the fragment of text on the screen and get the cause, the fix and the part to check. Controller alarms, height sensor faults, chiller codes — with the workshop answer next to the manual quote.

Also free, all controllers.

Your machine is waiting. This takes a minute.

Five photo diagnoses a month on the free tier — enough to fix a bad shift. Parameter tables and error codes are free without limits.
