My co-developer Paul has finished coding the Arc Assistant, or what we are now calling the G-Code Visual Editor!

This feature is available in the Virtual Laser Machine (VLM) tab and you can now write g-code on the left side in the G-Code Editor -- or -- using your mouse to click and drag Lines and Arcs on the right side in the VLM canvas itself. As you visually do this in the VLM canvas, the g-code of that object is dynamically updated on the left side in the editor itself.

This will be released as 1.8.2 soon.

Paul also made the video tutorial on these new features: https://www.youtube.com/watch?v=D_BXrJOb_vA

If you're interested in learning g-code, then this is now the best editor to be using....it is also the most cost-effective G-code editor now on the market. The Arc Assistant and Line Assistant are exclusive features of BCL.

The most difficult part of learning g-code (arcs, curves, circles) is now the easiest part with the new G-code Visual Editor in BCL!

I think Paul did an outstanding job on this feature and I'm sure you'll all agree when you see it.

I got an email today...they said they will send me the whole laser machine kit.

I've gone to a steel mesh screen and magnets to hold down my 3mm plywood, but when I was using honeycomb, I bought mine here:

I've just brought mine from local 3D printing guy for 18EUR, produced from a bit better material with carbon fibres. Can't wait for laser module  8)

I have this design from @pawpawpaw85 and it works very well...!!! Not a lot of air but enough to keep the smoke away, no fire flair ups and clean line burns...!!!

He also has the option to post news and updates here: http://benboxlaser.us/index.php/board,69.0.html

That may happen more often than you want, so the newsletter is a good idea too.

We can thank the Blue-ray industry for our laser diodes. Their manufacturing volumes improved yields and funded research into higher power devices.

@nc -- looks like I stand corrected...by George...!!!

>There is not enough water in the alcohol to clean the hairspray off the bed.

I use standard blue Windex (window cleaner) to clean my glass bed after about every 10 jobs.

Good point Richard...I had to buy extra bearings too as one or two that came with my 3D printer did not slide easily for some reason, so I replaced them.

For those yet to get a machine (3D or laser), make sure you slide your bearings on all of the rods in the kit...make sure they all slide easily...if they don't, you'll need to replace a bearing or a rod, if the rod was slightly bent! Fortunately, the bearings and rods are inexpensive.

I have both sitting on my parts shelf, ready to come into the game if needed  :)

I like that design...I've not seen that one before. My 3D Printer has those bearings and they work very well.

I do have to say that my aluminum bed plate (that the hot bed mounts to) had a cost saving design: it used 2 of those bearings on one side and only one bearing on the other side.

Fortunately, there were aluminum plates on Amazon and eBay that were made 'correctly' with 2 bearing holders on each side, so I bought that design and its worked very well.

So I think those kind of bearings on those rods would work well too. I like very much that many of the parts are 3D printed...means I could make my own replacement parts if needed.

>hair spray

That's what I use on my 3D Printer and it's the best thing I've found that works!!

>EVA foam.

I've not tried to laser cut that material. But I can tell you with absolutely certainty: try that material with your current low power laser machine and see if it will cut it. If it does, you will have saved yourself a lot of work and time and money and grief by not having to buy a $400.00 CO2 laser machine.

As a side note: if anyone is thinking about buying a $400.00 CO2 laser machine, and actually thinks you will be able to use it, as is, after getting it setup, your chances of that happening are slim. Not impossible, just slim. There are way too many pitfalls and problems and, more importantly, safety issues with these so-called 'low cost' CO2 lasers from China. The safety problems are the most critical as they can stop your heart when you touch your machine if it is not grounded properly or at all!

The chances are very good that you will need to spend more money on your $400.00 laser machine before you are done with it.

All you have to do is watch about 10 or 20 Youtube videos that folks have posted about the problems they have run into with these 'low cost' CO2 laser machines.

In summary: see if the laser machine you have now will cut your EVA foam.

>that it is non-sense to use any of them for Blu-ray Laser Modules.

Our typical laser machines do not use lasers out of a DVD player...or at least I am not aware that is the case?

Here is the only place I've found and it assumes one is going to use Mach3.
http://www.buildlog.net/sm_laser/drawings/_Buildlog_Mach3_Laser_Arcs_inch.pp
But building a custom driver is possible.
I am going to try T2L now.
Interesting that the Arduino Nano does not use the same USB mini as the clone supplied with the system

That link is for Cut3D and that config file won't work for our laser machines. And if the link assumption is that you're going to be using Mach3 (which is CAM software) then it won't work again.

So far, based on the information presented, I'd say you can't use Cut2D with our kind of laser machines.

I guess you don't have a link for the 2D configuration file?

Since you already have Cut2D and all you need to do is cut out parts, it may end up working well for you on your laser machine.

Do you know yet if the g-code generated by Cut2D will work on your Grbl-based laser?

Do you have the ability to edit what g-code commands it generates?

For example, can it generate these g-code commands?

Code: [Select]
G91
G21
G01 X0000.0000 Y0000.0000 Z0000.0000 F600
M03 S300
G01 X0010.0000 Y0010.0000 F150
G01 X0000.0000 Y-0010.0000 F150
G01 X-0010.0000 Y0000.0000 F150 ( pass 1 )
M05 S0
G01 X0012.0000 Y0000.0000 Z0000.0000 F600
M30

If so, then I think you're home free! If not, then you will need to be able to edit the g-code commands that don't match, so that they do match, and then you'll be home free!

To clarify with an example of what I mean:

If Cut2D does not generate

M03 S300

then its g-code won't be able to turn on the laser beam. However, if you can edit what it uses to turn on the laser beam, such that it will spit out 'M03 S300' as an example, then you'll be in good shape!

Keep us posted on how it goes...I'd like to see you successfully use Cut2D in your gasket projects. Like I said, I liked Cut2D when I was evaluating it.
