General Discussion / Rotary axis without motor
« on: November 01, 2020, 08:07:15 PM »
Four wheels attached to the Y axis ...
I thought about doing something to engrave wooden cylinders, but I believe that the diameter of these wheels cannot be any measure.

Engraving / Halftone Pics Software (Free)
« on: October 16, 2020, 01:34:37 PM »
I don't know if anyone knows, but I found it very useful.
It was designed for a CNC router, but I think itís okay to use with the laser too.
This "newspaper photo" effect is really cool.

Assembly Help / NEJE DK-8-KZ with Eleksmana Board
« on: October 10, 2020, 09:11:22 PM »
Can I control this machine with this board?





It works with a USB 5v and another USB for data, but it is also necessary for full operation. They are DVD drive engines.

Engraving / GRBL 1.1e burning weaker
« on: October 06, 2020, 08:15:51 PM »
with GRBL 1.1e the laser does not work at max power, with 0.9i it seems so, both the 5.5W and 15W laser.
Would anyone know what happens?

Trouble Shooting / Connecting the laser directly to the source
« on: October 05, 2020, 09:47:42 PM »
I use a 15W laser connected with this three-wire cable, where yellow is wpm ... everything works ok.
I decided to use the cable from the third photo, which came with the laser module, in this, the wpm wire (red) I call where the yellow was in the first photo, but the laser is always on at max ...
What am I doing wrong? it seemed to me a logical thing.

Cutting / DXF opening different on T2
« on: March 05, 2017, 07:23:54 AM »
I do not know what happens ... I downloaded this .dxf file, which opens normal in Corel, but in T2 it opens like this in the image ... Inkscape also opens different

Cutting / How to order the lines to cut in T2?
« on: March 02, 2017, 07:35:34 PM »
How can I order the lines to be cut first in T2?
I would like the contour rectangle to be the last to be cut, to give stability to the inside pieces until finished.
The wood blade has 1mm and a slight change in the angle of cut and focus.

Engraving / Bitmap changes size in the Benbox
« on: September 09, 2016, 06:20:42 PM »
I set up in Corel image size for 40mm width, already in vector; I export as bitmap (jpg, png or bmp, whatever), when I open in the Benbox it is almost 50mm ... if open it in Photoshop, the image shows the correct size, but not in Benbox ... I see that changing output resolution (300dpi, 96dpi or other) that size varies.
What resolution should I use to keep the 40mm? or what else needs to be done?

General Discussion / My laser was weak
« on: September 01, 2016, 04:03:28 PM »
5500mW
it cuts wood thickness of 1mm Intensity: 255, Speed 300 at once.
Now with this same configuration spent ten turns and still not gone through the wood ...

Does anyone know what can it be?

Engraving / Engraving Glass - 5.5W
« on: August 30, 2016, 04:47:54 PM »
Today, in order to flatten a thickness of 1 mm wooden sheet, which insisted on staying bent, put a piece of glass to flatten it and cut a straight line ... I saw that the glass was a scratch and decided to try giving more importance to the glass.
I was surprised with the result, I thought I could not do this with a laser 5500 mW ...

Written in Benbox own.
Intensity: 255
Time: 200
Scan by Z
Discrete

Only a white paper beneath the glass sheet

T2 Engraving / Some questions from a newbie
« on: August 29, 2016, 11:24:28 AM »
First of all, sorry for my poor English.
Beginner in the laser world, bought a 5500mW 50x65.
Experimenting Benbox, I discovered some things and some doubts arose:

- Time is for Discrete and Speed is for Continuous, is that right? It does not have difference between 300 or 1500 Speed if you are in Discrete mode? and the same with Time when in Continuius mode?

-It has some way to let the laser beam in the center of the design and not at home before starting in Benbox software?

-the card where is the Arduino does not have the jumper v0.9, can I use software other than Benbox?
I found it interesting the T2 Engraving interface, Benbox not have many options.

Thank you and I hope to share a lot of information that is for me a new world.
I do not know if I can leave here my facebook, where I put my work which from now on will have content laser.

EDIT: Now I saw that I posted in the wrong area, sorry.
