CAD Software / Re: Order of lines in dxf

You control the order in which you want to burn your drawing objects inside your CAM software.

Therefore, it should not matter in which order you create your objects in your CAD program.

And in fact, that model frees you to focus on your drawing objects without having to worry about their order of creation. I'm sure T2 allows you to control your burning order.

The bottom line here is that you should not have to control this in your CAD program.

Red paper will not reflect the laser beam...back to the underside of the acrylic plate...white paper will...

To laser clear acrylic, using our little machines, because they don't have enough laser power to actually burn on the top surface, you have to use this trick:

1. Lay a piece of white paper down on your work area.

2. Lay the acrylic piece on top of this white paper.

3. What ever your burning, you have to mirror the image or text.

4. Now you can laser it and it will actually burn on the bottom side of the acrylic.

(Obviously make sure your laser focus is on your spoil board, the bottom side of the acrylic plate).

Drop the quotes if you used them.

I did a search on grid and found many posts.

As far as I know at this point, I will be supporting very basic commands so any Grbl version should in the future.

I'm not writing the CNC code for Grbl. No more room for kerf, remember?

I'm writing the kerf code inside BCL, with help from Paul.

>Any thoughts on how to "standardize" the GRBL?

for what? CNC?

BCL CNC Update:

I've had to re-think my position on BCL having CNC capabilities. I was talking to a friend of mine who is a machinist. I told him since BCL already supports the Z axis, users can write their own g-code now and make use of router/cutter tools. He told me he used to do his CNC work that way back in the 'old days' but now it's all done in the CAM software and he wouldn't want to go back to hand coding his g-code.

So, I've had to re-think this and now realize BCL will have to handle the radius compensation/kerf since Grbl has no room to do it. While I do still think this is a lot of work, I'm moving forward with prototyping this capability into BCL right now. I think this might take some time and I am starting with Circle objects.

If any of you are interested in helping me to design and test this new CNC functionality, please contact me. I can use your help and input.

Check your other com port parameters (data bits, stop bits, parity, etc.).

I eliminated that one as it is a trial version and costs $1500 with no mention of what the 'trial' actually is.

You beat me to it...I was going to say, their software is very expensive...!!!

Unfortunately, there is very little affordable classic CNC CAM software. I did some research on this about a year ago. 90% of it is not cost-effective for our segment (low cost machines)  :(

Sorry, I mis-read your statement the first time.

It's not open source. You have to pay for it.

Make sure your settings are being 'remembered' in your Grbl firmware.


...sets your max speeds.

I was hoping for a site with "experts" but opening a group here would be fine. Limited to "Mini CNC" or open to generic machining would be the question. How many members also have traditional CNC equipment? Are the design tools different?

OK, I've added Mini CNC to the forum.
