Here are some of the grayscale engravings done using T2. I had some time experementing. I will be posting images with settings.
Setup:
Eleksmaker A3
Mana SE board
2300mw TTL laser

This was the image used as a test image to get proper calibration/settings.

Engravings are done on mdf, cardboard. I will be updating this thread with many other materials. My initial results were from charcoal like to very light.

Here is one of the tests.
Speed: 3400
Res: 0.15
Diagonal engraving
Power: 25-255

Shades look good. But small details are shaky. So either I have to stabilize the engraver mechanically or lower the speed and power to compensate it.

Test2
Speed:2800
Res:0.15
Power: 25-210


I will be using above settings for most of the engravings on mdf.

Let's start with cardboard. It's tricky to engrave as it quickly turns to charcoal at power abrove 110 even at high speeds.

Speed: 3200
Power:30-100
Res:0.1


Speed: 3200
Power: 20-65

Let's move to mdf.
Speed: 3400

I upgraded to mana SE board and 2300mw ttl laser. Can anyone provide proper wiring instructions? I searched few threads but couldn't find proper answer. Please refer to pictures and suggest wiring instructions. I understand two connections for laser and two gor ttl.I don't want to mess up connections.
