Are you using Benbox software or BenCutLaser software? They are different.

BenCutLaser / Add Text Feature Correction
« on: December 22, 2016, 10:14:09 AM »
Paul reminded me that your MText can be left flushed when you paste it into the text pane of the Fonts Properties dialog window and you can use the Anchor Point field to automatically center multi-line text. In the Add Text video I made, I didn't use that preferred method but instead I was manually centering the text which is not necessary to do.

Please see attachment.

Thanks @Zax,

I down loaded the zip file from them and opened up the .dxf file in QCAD. While you can use it the way it is, I divided up the drawing into two files for better efficiency in BCL. I'm posting the two files below, along with the screen shots of what they each look like inside BCL. They are now very efficient files from a drawings object count perspective. I also moved the drawing objects into positive X,Y work space.

3mm.

He has a working Z axis and has extensively tested BCL's Z axis feature. He cut this 3mm project in 4 passes, using a Z axis drop of 1mm per pass.

His next project will be to cut 6mm wood.

One of my BCL users made this Star Wars fighter.

Welcome to the forum...!!!

I'm NOT telling you or anyone else NOT to buy one of these...what I'm about to post is to educate you and anyone else who might be thinking about buying one of these CO2 lasers. @Zax has one, so what he has to say about them is important.

I don't own one -- but -- I have watched many Youtube videos on these lasers. If you do that it won't take long to discover that these are a very different breed of laser than our low powered laser machines: they can be much more dangerous to assemble correctly, get working correctly and to keep working correctly.

First, many of the kits do not have grounding and since they use 110VAC, there is a lot of voltage going into these machines. There are some Youtube videos showing several people getting electrical shocks just by touching the case or the frame inside. You should know how to determine that you have assembled your kit correctly and that you have a proper electrical ground. If you don't know how to do that, you may find out the hard way that you'll have to learn...and fast!!

Inspect all the wiring and you'll find no shortage of short cuts taken by the factories. You'll have to do some rewiring to make your unit safe to operate. If you don't know how to solder, you will soon learn!

As @Zax pointed out, there is a lot more to taking care of the CO2 laser unit itself, what with the cooling setup needed and how critical it is.

Don't go into buying one of these thinking it's 'similar' to our low power laser machines...it's a different, more complicated breed of laser.

Finally, you can use almost any CAM software out there but there is one big problem: Most of the classic CNC/Laser CAM software is expensive...very expensive...so finding an affordable CAM program to work with these CO2 controller boards and the firmware they use is doable but not necessarily easy.

I assume @Zax has made sure his T2 Laser works with his C02 laser so there is an engraving/cutting CAM program that you may want to use, and compared to the cost of the classic CAM software, his $39.95 price is a bargain.

As the developer of BenCutLaser (BCL), I'm not aware of any of my users using BCL on a CO2 laser, but there is no reason I can think of as to why it would not work. In fact, it would be easier as far as setting up the laser tools than it would be on one of our low powered machines. It's the same price as T2 Laser so its affordable if you compare the cost to most of the classic CNC CAM software.

If you end buying one of these, please post pictures and tell us what you bought and how the assembly went, etc. I'm sure there are many who have assembled their kits and had no problems...then there are others who had no end to problems...you never know what you'll get until your start in on it...!!!

How did he connect the Laser? With a J tech Driver ? China TTL or directly to the Ramps1.4 this is where i stuck at the moment ..

Kindly Maurizio

He purchased a 3.6w laser diode from JTech...

There are 2 version of Merlin running with Lasers and also GRBL for Uno and Ramps 1.4.

What about CAM software? LaserWeb? T2 Laser? BCL?

I've been working with one BCL user who is running a converted 3D printer frame and Z axis setup with a RAMPS 1.4 controller and a Mega2560 board from gCreate...gCreate has slightly modified a version of Marlin Grbl themselves...I've now got BCL working with his machine...we're just in the final throws of making some final tweaks to my software. Then I will publish the results of this new project.

I've always thought how neat it would be to convert my own 3D printer to a laser machine...(I have a RepRap Prusa i3 with a RAMPS 1.4 controller and a Mega2560 board)...it would have a really nice heavy duty built-in Z axis...this project will be added to my To Do list of projects.

I bought this 3D Printer: https://folgertech.com/products/folger-tech-reprap-prusa-i3-clear-frame-full-3d-printer-kit-ramps-gt2

I've been extremely happy with it.

BenCutLaser / Grbl 11e is now supported by BCL
« on: December 17, 2016, 06:49:22 PM »
While Grbl 1.1e isn't really needed by BCL, to maintain firmware compatibility with T2 Laser, BCL now supports it. So if you use both programs, you don't have to change firmware if you run 1.1e.

1287
Which software are you planning to use with your new setup?

Trouble Shooting / Re: Cant open dxf file in T2 Software , any ideas?
« on: December 17, 2016, 12:13:37 PM »
T2Laser will handle the no units and older format issues, as I showed it imported correctly just not what he wanted.

I verified with multiple other programs including AutoCAD's own viewer, TurboCAD and Inkscape and the result is the same.

Yeah, I was sure T2 did...for clarity, BCL is using a DXF Library and that's why I'm more restrictive on the missing Units and .dxf files older than 16 years.

@Zax, my 2 cents because I get these same questions from users trying to load a .dxf into BenCutLaser:

1. The drawing has no Units of Measurement set at all. Users should always check their dxf files and make sure that a Unit is set. BCL won't initially load a drawing with unknown Units.

2. The drawing was done using an AutoCAD format older than 16 years. Users should save it to a more recent AutoCAD version such as 12 or 13.
