T2 Engraving / Ich brauche Hilfe von deutschen Sprechern
« on: May 26, 2016, 09:29:42 AM »
I have a German speaking user that is having some trouble getting T2Laser to work.

I gave him the forum link but because he doesn't speak any English he is not comfortable to use translation to request help.

Would anyone be willing to help him by e-mail?

Please PM me if you can, and I will forward you his information.

Thank you,
Zax

T2 Engraving / DXF Export
« on: May 13, 2016, 04:44:40 PM »
Here's my quick guide to exporting DXF files from Inkscape or TurboCAD.

It's fairly simple with both programs, but TurboCAD is the easiest.

General Discussion / Technologies
« on: May 11, 2016, 11:28:08 AM »
I know the majority of low cost machines are filament extruders but there are other technologies like the powder and liquid resin systems that use either a laser or projection type system to fuse the material and create layers.

Does anyone have experience with these? They seem to offer much improved speed and resolution and I've seen some kickstarters where the price is reasonable (under $2k).

If not, do you have any advice on which extruder systems are better or just what to look for and stay away from?

T2 Engraving / Single line engraving fonts
« on: April 29, 2016, 01:24:27 PM »
I have found these single line fonts useful, also if you search for "stencil fonts" they can be useful too.

T2 Engraving / Sketch feature
« on: April 22, 2016, 11:59:55 AM »
I would like some feedback on the sketch feature, so I know if it's worth me spending any additional time on it (adding more features, load/save etc.).

I found this design online and decided to make one... and yes, it turns and works, very fun.

Flashing Firmware / Some Grbl firmware
« on: March 21, 2016, 11:36:19 AM »
Here are 3 useful hex (firmware) files:

Eleks Maker (Benbox): LX-Nano.328p.20150626.hex

J-Tech Grbl 0.9 (optimized for laser scanning, 1kHz PWM): jtech_grbl.hex

LaserInk Grbl 0.9 by nickw89509 (optimized for laser scanning, 7.8kHz PWM): laserink_grbl.hex

The default laser pin on Grbl 0.9 was changed from D12 to D11 as it provides PWM support, if your board doesn't support this (there may be a jumper located under the Nano) and you don't want to cut traces and modify it then you will need to re-compile the hex and comment out VARIABLE_SPINDLE in config.h

I have tested these and they are stable, but if you want to ensure you're using the latest version just do a search on Github.

T2 Engraving / T2 Laser
« on: March 14, 2016, 11:20:43 AM »
I need a couple more people to test out my software and provide feedback  ;D >:( :( :o .

It has been thoroughly tested using Windows 7, and I confirmed it works on Windows 10.

Best results are currently achieved using J-Tech or LaserInk Grbl branches.

It supports PWM for greyscale images, black/white conversion for text and graphics, (basic) dxf import for vector cutting.

You can save the G-Code and just use it for conversion, run the machine with it or use it as a viewer with S# support.

It can be downloaded here: http://benboxlaser.us/index.php?topic=41.msg272#msg272
Then PM me your "User ID" and I will give you a license key for the full version, including minor updates.

Update: All free license keys have been spoken for, trial version is still available of course.

Other Software / T2Laser Software
« on: March 08, 2016, 05:03:18 AM »
First some background:
I purchased a Banggood A3 2500mW laser for engraving and quickly realized the Benbox software had some limitations. I decided Grbl was the way to go, and started testing alternative software. The only one that came close to doing what I wanted was PicLaser, but the pro version with their sender program is over $100 and it's user interface could use some work (my opinion).

So, now what?
Well, I'm no programmer but I know enough to be dangerous so I started writing my own software.

The result... T2Laser!

(I am attaching a pdf showing some of the features and screens)

Other Software / Image to Gcode
« on: February 19, 2016, 05:18:53 AM »
What is everyone using to convert images to gcode?

I have tried several options, and the 2 that seem to work the best so far are piclaser ($) and 3dpBurner (free). The problem I have been having is the files are huge due to the very small steps and this causes a lot of stuttering, so I am now testing other programs to send the gcode to grbl and see if I can find something that works better.

Interested to hear what others have tried and what worked or didn't.

Thanks,
Zax.

Grbl Controller / Grbl options
« on: February 12, 2016, 05:14:26 AM »
The current master Grbl v0.9j https://github.com/grbl/grbl is compatible if you change the jumper under the Arduino to 0.9 or compile it with pwm disabled (comment out VARIABLE_SPINDLE in config.h).

It currently flushes the buffer on spindle commands which may cause problems with lasers (this is likely to be resolved in a future release), so you may want to use one of the modified branches that are laser specific.

Here are some of the options:
J-Tech (this is a hex you can flash to the Arduino using xloader), uses S0-255 to control the laser power by PWM.
LaserMod by idanielrobert (supports laser or cnc using $L command), uses Z0 to Z255 to control laser power.
LaserInk by nickw89509 (works with PWM or digital on/off laser), uses S0-255 for laser control when in PWM mode.
LaserMode by Andy (popular for grey scale photo engraving)
9gMod by Nefa, uses $Z# command to set laser power

There are others, I just haven't tested them yet. Please post any others you have tried and the results.

A huge thanks to Sonny Jeon (chamnit) for his support in getting Grbl to where it is now and it's continued development in the future.

Other Software / Must have software, tools and other fun programs
« on: February 02, 2016, 03:22:12 PM »
Arduino IDE, Grbl, Benbox, XLoader and WinAVR (obviously!).

1. Inkscape with raster-to-vector (engraving) and vector path (cutting) plug ins.
2. Grbl Controller (I prefer this to UGS)
---------- below are optional ----------
3. CAMotics, previously OpenSCAM as a GCode viewer (although not necessary)
4. Eleks G-Code Tool aka LX Easy (doesn't do anything you can't do in Inkscape)
