T2 Engraving / Grayscale Engravings done with T2
« on: July 03, 2017, 12:05:43 PM »
Here are some of the grayscale engravings done using T2. I had some time experementing. I will be posting images with settings.
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.

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

Speed: 3200
Power: 20-65

Speed: 3200
Power: 25-100
Res: 0.1

Let's move to mdf.
Speed: 3400
Power: 20-255

Speed: 3400
Power: 20-255

T2 Engraving / Mana SE led D4 blinking [Solved]
« on: May 30, 2017, 10:50:58 PM »
I upgraded to Mana SE board for better pwm control. I hardly experimented on few images and after that the board stopped working. It's led D4. It's solid when working normally. Now it just blinks continuously after connecting to power. Nothing happens. I contacted banggood for this issue. Has anyone encountered similar issue with Mana SE?
Solution that worked for me:
Please go through thread if you have similar issue. Removing 16V capacitor worked. I will replace it though.

T2 Engraving / Wiring for Mana SE to ttl laser
« on: May 11, 2017, 08:04:35 AM »
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.

T2 Engraving / Advice needed for PWM upgrade
« on: April 26, 2017, 09:26:03 AM »
First I want to thank Zax for T2. I have been using it for few months and it's an amazing package. Please keep on updating and adding more features in future updates.
Now, my question. I am interested in PWM functionality to produce grayscale images. I have Eleksmaker L7, 2500mw. I can't get a linear response for 0-255. I searched some threads. So I am interested in buying new laser module, rather than opening existing one and making new connection and new driver. Will this work as a replacement? Suggest a link if it's not compatible.
Also, I am not sure about connections to nano. There are 4 wires. Can anyone guide me how to connect those? And if I upgrade to new Mana SE board,does it make wiring simple?

Any practical difference between 2300mw vs 2500mw?
