Hi!
Is there a similar way to paint copper areas (instead of painting non-copper) in 8.5? Useful for milling off soldermask from pads.

I am running ver 8.5 and can not enter ANY data in the command line...what am I doing wrong?

...only now I'm looking for a way to edit the silkscreen. I have a couple of 0603 leds and I want to eliminate the symbols on the PCB in the silkscreen generated by EasyEDA. Th elaser blows away too much isolation...

Thank you, exactly what I was looking for!

It took a few min to figure the CMD line and how it functions in flatcam in windows 10.
it would be nice if this was sampled in the manual. but over all it is an awesome program to with.

First of all: Thank you for this great program. It is very powerful.
I am trying to sensitize negative dry film with a 405 nm laser and my cnc.
I would like the track of the gerber tracks to be traversed by the laser giving as many passes as necessary to complete the width of the track and draw the pads completely. I have seen that the post of drawing serigraphy is very close.
Does Juan Pablo consider it interesting that FlatCAM does this work?
If so, I would like you to tell me when you are planning to do so.
If you need help I could collaborate on its implementation, although I do not know much about python. But everything is learned! By the way, I'm from Spain. You speak Spanish?
Regards, and thank you very much

Re: Board Cutout with FlatCAM

Yes Anish, that is exactly what the video shows and what I just explained.

I suggest you use the "Discussion Group" in flatcam.org for an extended discussion on how to achieve your particular goal.

Thank you for your reply,
I am attaching the PIc of PCB Board . Can u let me know if it is possible to cut the PCB Board on Flatcam software or not awaiting for your reply.
Thank you.

Hi Anish,

I did not make this video, but the way the speaker gets rid of the internal path is quite clever. The problem is that the internal and external paths are the same object. That is why you cannot select them separately in the beginning. By cutting a piece out of it (what he does with the rectangle and the "subtract" tool), the complete group of lines is broken into separate pieces. Now you can select the interior independently and delete it. He does "update geometry" several times, but this is not required.

You can also take a look at the "interiors" or "exteriors" shell commands. Those will select and create an object with just the exteriors or interiors of any geometry object. Just type "help exteriors".

Cheers,

Hi, I am Anish From Mumbai INDIA, I am Facing some problem with Flatcam Software 8.5 virsion.
I want to cut the pcb Board in odd design.
I am loading the PCB Cutout File. Selecting the options as per the youtube video to cut the Board but the inner Boarder is not getting deleted. I only want the outer boarder for cutting not the inner one.
Pl. Guide me

Hello Mr. Caram, It would be good to see EasyEDA.com added to this list. The system is very stable, reliable and easy to learn. The user interface is very pleasant and responsive operation.EasyEDA has a rich library of thousands of electronic components (for both circuits and printed circuit boards, and for modeling), and tens of thousands of examples of schematics! Anyone can use this library and expand it. It also can import existing designs done in Altium, Eagle and KiCad and then edit them in EasyEDA .
Moreover, another outstanding feature of EasyEDA is that users can access to Open Source modules developed by thousands of electronics engineers.

Juan,

Looked at the article you suggested but we had a crazy rocket ship "shape" to cut out. The silkscreen article was actually more appropriate as we traced a line that was imported into Eagle before turning the .brd into a gerber file.

Thanks for suggesting the other article though!

You are welcome,

Also take a look at this tutorial, http://caram.cl/software/fl..., which is more specific about board cutouts.

bill gertz — Mon, 06 Jul 2015 12:10:27 -0000

Hey Juan,

Thanks for the article it was useful not only for cutting the silk screen into the board but for cutting out a specialty board with a PCB-USB connector. In our case we treated it as an iso cut but specifying a cut out bit with a depth sufficient to cut out the board.

Thanks!

Re: Impact of the Magnetic Levitator

jpcaram — Mon, 16 Mar 2015 10:12:34 -0000

There is an infrared LED shining into a photo-transistor. The metal piece is partially obstructing the light path. If it goes any higher, there is less light shining onto the photo-transistor, therefore conducts less current. If it goes any lower it will expose the LED even more, causing more current to flow. The interesting fact there is that there is no need for a precise measurement over a large range, but only around its intended position.

I don't really know why it is rotating, but it is certainly an unintended behavior.

Very Awesome. How did you measure the height? And why is the levitee rotating?

I had a corrupted version of Acrobat. I re-installed and all is well. Thanks

It looks fine in Acrobat. What are you using to read it?

JP,

It seems like major portions of the document have missing formulas etc.
