How many wires between the controller and the laser module. I have 2, 3, and 4 wire fixtures.

I get an error 404 when trying to download the test files.

Cutting / Re: Cutting Plywood with 2.5W

The air blower removes soot from the trough and helps keep it from settling on the surface of the material. You do not need much air pressure. A small aquarium air pump is usually sufficient. Regular plywood has glues that do not cut easily with a diode laser. I suspect it will take a lot of passes at a slow burn rate.

T2 has the required firmware and update tools.

Did you plug in the steeper drivers upside down? (Never personally done that :-X)

I thought I saw one pin misaligned.

1. @Zax - does it burn ok on you setup?
2. I use Linux and svg files. The conversion from dxf to svg was absolute junk.
3. Converted from dxf to png but the scaling was was off. Perhaps it is missing the units.
4. Is the problem on shape starts, ends, or someplace in the middle?
5. Is it repeatable? Isolate one or two faulty shapes and test.
6. Test burn on cardboard with low power. Does it complete ok? Up the power and retest.

BTW - I opened the dxf file in 3 different viewers. All displayed ok. Converted wrong.

Please post a design file that exhibits this behavior. Looks like the individual shapes are not closed.

How!!!!

11
Do you have random low intensity junk in the design file that only burns the mirror when etching slowly?

I don't understand the square wood looking pattern. Are you burning thru the mirror or from the back side? I usually put a piece of white paper on the waste board to protect the surface from scratches. Suspect it helps keep the char from the waste board from getting on the surface.

What power laser do you have?

Don't forget acceleration. If it is too low the unit will never get up to speed and just linger on a small area.

I do about 5 mirrors per week and have no idea what your first 2 pictures represent. If you post the design file I will examine.

Some notes:

   1. There are at least 2 layers of coatings on the back side of typical mirror.
   2. It is possible to burn off just the reflective layer and not touch the glass.
   3. It is possible to fracture the glass.

You can get a 3D look by just burning the paint and reflective layers, leaving the glass untouched, and applying more heat elsewhere to get a frosted appearance. It takes testing and varies with each vendors product.
