RC Modelers
« on: July 11, 2016, 03:49:29 PM »
I'd like to have a look at what kinds of .dxf drawings you RC Modellers create.

I want to make sure BenCutLaser (BCL) can support your drawing types so that you will be able to cut out ribs, rudders, flaps and other parts.

BTW as many can see from my Youtube Channel, I am also a big Microsoft Flight Simulator user and have made a lot of high quality B-737NG training videos.

You can email me the drawings and I will do nothing else with them except make sure that BCL can support them.

Thanks...

The plans I'm most familiar with are in PDF form. Not sure what it would take to implement but being able to import a PDF would be really nice.

The cutting software I used at my local hacker space would import a PDF and then allow you to assign colors to each line or object. Then you would assign your power and speed settings. The cut order was determined by the color code and seemed to fall in line with the order you see the colors in Inkscape.

Here is a website we used to quickly design boxes for laser cutting.

Most of these plans come as PDF's. I found I can convert them to something useable in Inkscape.
The planes are mostly constructed of Readiboard and poster board.

http://www.goadams.com/products/readi-board-foam-board/

It is found at Dollar Tree stores. There is a newer board that is water resistant. Size is 20" X 30" X 0.4". My Brother is going to scale up an A5 2500mw to cut this board. So far we can cut through the first paper side and down into the foam but have not cut through the paper on the other side.

Your Bencut laser will probably be what we end up using as it supports "tools".

The easiest way for BenCutLaser to support .PDF files would be to simply convert them into a .DXF file format. I will look around for a free online conversion tool and see what I can come up with.

I ran your .dxf files through my .dxf library xray tool and identified the drawing objects: Splines. All splines and nothing but spline entities.

OK, so this is the information I was looking for...I will have to now add Spline drawing objects to BenCutLaser to support you RC Modeller folks.

Thanks for helping me to help you...

My brother mainly bought the Laser for cutting from R/C plans. So I am sure he will appreciate your work. He wants a low cost way for people to build these planes without having to resort to expensive cutters.

Sounds like we made more work for!

I think Splines won't be that hard to add...I believe their structure is similar to Polylines (to a lesser degree) and Ellipses (to a greater degree)...I have not dug into them yet, but I don't think they will be that hard to do (famous last words).

My goal is to try and support this community as much as I can with BenCutLaser, within reason...when I first got my laser machine, this is the software I was missing...now BCL is about 80% finished and I can now see it coming together as envisioned, to make my 3mm wooden parts.

For the new members, we have to remember that I spent months and months last year talking to CAM software developers, asking if they could, if they would, modify their complex CAM software for my low powered laser machine...no one was interested in supporting us...no one...about that time I started this website and @Zax was an early member and it has just exploded since those early days. There was a demand for this kind of support for our machines. Now this community is going to get the option of using two specifically developed pieces of software for these little machines: T2 Laser and BenCutLaser.

Last year I contacted MakerBot and asked them if they would support a CAM application...at the time I was trying to get another CAM company to modify their software for us and thought if MakerBot got behind them, they would make the needed modifications...but the CAM company changed their minds and said they no were no longer interested...this month, I'm introducing BCL to MakerBot to see if they still have an interest in providing their customers with a CAM program (BCL)...and I will also mention T2 Laser on @Zax's behalf.

As far as I know, @Zax and I are the only two software developers targeting these little laser machines.

RC airplanes was also the thing that got me interested in these diode laser cutters. Currently trying to make my own plywood since I cant find ones that cut well, but balsa seems to work great!
I'll try downloading the 0.8 version again on another computer and hopefully it wont give a false positive on the .exe and see if it can import the dxf from solidworks properly.

And now slightly offtopic but very important for BCL!:

I would strongly suggest that you stay away from Makerbot;
they have earned a really bad reputation of patenting things that other people come up with.
They may steal your ideas, patent it, and start selling it without you the creator receiving any kind of compensation,
as well as making it impossible to sell the thing you come up with as you might receive a lawsuit. Be _very_ careful please!

Thank you for the heads up...I didn't know that. I'll steer clear of them.

This  prog for CNC cutting of airfoils/wings etc   has been around for years.  It is well known....and covers the whole area of aeromodelling wings in   balsa/ply  and  foam  wings  and fuselages.
I  believe there is also a US prog very similar  (or used to be). It had a vast library of airfoils to choose from and insert.

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

SAFETY -  IS NO ACCIDENT

Sorry I had the wrong spelling. I meant to say MakeBlock not Makerbot.

I think what Ross said, Profili 2 is what alot of people use. I for the most part have been using pdf , print it out on a large box label, stick it on the wood and cut it out with scroll saw. The laser is what I want to use. The scroll saw works very good , I can stack up 2 inches of 1/8 or 3/32 balsa and cut a whole bunch at one time. It would be nice to be able to use the pdf file , load it into the machine and let it do its thing.

BCL can only support .dxf files. This is the standard for CAD files. I'm going to rely on figuring out a way to convert PDF file drawings over to workable .dxf files.

As an FYI -- it is not a small task to 'add support for another file format'. There is a massive amount of code needed to support a new format. Each format is different thus all the dxf code would be unusable for the pdf file format. In BCL now, at least half of the code that is there is related to supporting .dxf files. It's just a huge amount of code.

A PDF to DXF converter would be far easier to do than for me to spend another 3+ months to code support inside BCL for PDF. I really do not want to go down that path. I think I can find a workable PDF to DXF converter of some kind.

Ralph, I drew a AutoCAD drawing of a part I was going to try to cut and exported it to BCL and got the message that the file was not usable by BCL. When I saved the file I used to AutoCAD 2013 DFX file format and all of the items on the drawing was lines. Do you have any suggestions, there were older versions I could have used.
