Tangent Corner / A Robin.

This little fella spent many days building a nest in my post-box only to have it destroyed by a fox (or perhaps a cat). Not deterred he went on to build another nest in my garden shed. The eggs have now hatched and the feeding frenzy has begun. He posed for this photo whilst looking for grubs.

Feature Requests / Re: Add a single line MDI with Enter property which executes like Mach3

« on: May 20, 2018, 01:59:39 AM »

As Steve has already explained you do not need to use your mouse and click Cycle Start.

Just enter your single MDI then use Ctrl-Enter to execute the command. http://www.machsupport.com/forum/index.php/topic,37370.msg255638.html#msg255638

I do wonder however whether the Mach3 plugin or DotG are smart enough to not stupidly scan the entire area line by line thereby going over large areas where engraving isn't necessary?

Nope

I think I found the answer, looks like it's as simple as, the optimal wavelength is the wavelength that is absorbed by the material.

Never really thought of it that way but it certainly sounds like a very good rule of thumb.

Share Your GCode / Re: G-code help

Hi Marcmora,

Welcome to the forum.

Firstly you need a high resolution image of the crest then it can be traced (various software available to do this - Inkscape is free) to produce one or more .dxf's (vector files). A Gcode file can then be produced from the vector file (again various software available to do this - LazyCam is free but there are better products available).

If you use a CAD/CAM software (such as Vectric Aspire) you could create a V-Carve type of crest (also check out F-Engrave - this is free).

Overall there is a lot of work (and learning) involved in creating the required Gcode but learning can be fun

Hi Bryanna,

It may be helpful if you could post a link to the new build version 3.043.062.

It's such a broad subject and documents I have seen only cover limited aspects of photon properties at various wavelengths so best to Google the subject and see what you find. The various laser manufacturers websites will often detail what their machines are capable of so that should be a start.
