3D Printing and Engraving

Thermoplastic polyurethane (TPU) belongs to a class of polyurethane plastics having many important properties such as elasticity, transparency, and resistance to grease, oil, and abrasion. It is unique due to its extremely flexible nature. Technically speaking, TPUs are made up of thermoplastic elastomers.

TPU has different advantages such as resistance to abrasion, ability to perform at low temperature, elasticity, and mechanical properties along with rubber-like elasticity.

TPU printing filament is flexible in nature. It can bend easily without any effect on the design, strength and durability. A mild soap can be used for its cleaning.

Flexible TPU filaments can be stored in a cool airtight container. Container may also have a desiccant pack, so that filament remains bone dry. This container can also help in preventing the entry of dirt and dust particles, so that the filament could be used anytime for print. Although some type of TPUs are water-resistant, prolonged contact with water could result in degradation of the product.

For optimal results print flexible TPU filaments on direct extruders; however, it is possible to print on Bowden extruders as well. Flexible TPU filaments have the ability to adhere well to most surfaces such as glass, aluminum, Kapton tape, and blue painters tape. It is important to always print in a well ventilated room regardless of the filament type.

Please Note:
1. Please wear laser goggles during usage and avoid touching the laser directly with your eyes or skin!
2. The red cord is DC12v(+),black cord is GND(-), yellow cord is signal(S). Please make sure you know the wire position and connect to the ManaSE board correctly!
3. Do not use the laser module for more than 30 minutes at a time


Packaging List:
1 x DIY 2500mW Laser Engraving Machine(assembly needed)

FAQ:
1. How to assemble the kit?
    The whole assembly and operating manual link is here:http://wiki.eleksmaker.com/doku.php?id=elekslaser_a3_pro
    You can also watch the video to do it:https://www.youtube.com/embed/_1ypts5489Y

2. What software can support this machine? And what image format? Engrave Mode?
    Supported Software: EleksCam,T2-Laser,  GrblController, LiteFire, Laser GRBL, etc.
    EleksCam can be found at http://wiki.eleksmaker.com/doku.php?id=elekscam
    Supported Image Format: jpg, bmp, svg, G-code
    Supported Engrave Mode: Photo, Word, Scan, Outline, Pixel Laser Engraving

3. What systems can the EleksCAM support?
    PC Windows XP/7/8/10

4. My laser doesn't work, what should I do?
    If the machine does not work, it might be due to:
① The wire connection is wrong.Please check the connection like the picture shown.
② Your computer could not support the software.Please use Win XP 7/8/10 to check it.
③ Software problem.Please check whether wires are inserted rightly. And then check your data settings.
④ The kit misses some accessories.Please compare with the instructions
⑤ Laser module/ driver board/power supply is faulty.
⑥ Laser module self-checking tips link at http://www.dropbox.com/s/nuuu98e3einfee4/Laser%20Tips.pdf?dl=0

5: My software shows: Not data, what should I do?
    There might be two reasons.
     ① You did not open  Administrator privileges to run the software.
     ② Your computer architecture is incomplete:check whether VC ++ and .Net and directX are installed

6. Can I regulate the laser power or is the laser power is adjustable?
     Our new Mana SE controller board can adjust the power. Please download our ElekesCAM software to do it.

7. Can I upgrade stronger power laser module by myself? Can I extent rail frame?
   Yes,you can. A DC12V laser module can be installed on this machine. The red is positive.You can also extent the frame by yourself, but we do not stock the rails.
 
8. When I click arrows to control the motors, it works. But when I begin to make it work with EleksCAM software,
    it does not move. What should I do?
    The EleksCAM could move by hand but could not move when focus.The problem is the area and language inside the system control panel.
    Please set the format to English and United States.Then it will be ok. Detail is shown in the wiki link above.

9. My laser module is always on and could not turn off.What should I do?
    Please try to connect the Signal(S) and GND(-).
    If the laser module turn off, that means the laser module is ok, the problem might be the ManaSE board or a software setting.
