2D and 2.5D machining - milling and engraving

This description is intended for beginners and those wishing to invest in software to a minimum.

The easiest way to start is to use Corel 11 and predatory Mach3. Machu basic setup will not be addressed here, because it is described in the description of Machu - setting rates, the LPT pins, engine tuning - Calibration ....

The desktop is the "self" and its corresponding štvtina desktop machine.

The center corresponds to the desktop coordinates X, Y, Z = 0,0,0

The contours are drawn, 0.001 mm thick lines

Some drawings must be converted to curves = click on the drawing and press Ctrl + Q



After writing the text is necessary to remove the fill.



Milling fill - thus entering the track cutters can use the contour - this also applies to the text and objects.


Offset is set to the average used router.

Thus ready artwork is ready for storage and export. For larger paintings can import into the Lazy Camu last longer in such cases is appropriate to use a CAM program to generate pathways, it is addressed in some other description.

When saving, it is appropriate to impose a duplicate - once as. Cdr and once in a format that is capable of mach import. This may be different for different versions of Corel. The most common is to DXF - HPGL or version Autocad2.6



This is a sample of the deposit in the Corel DXF 11




It is now possible to embark on the import Lazy came.



Click on the CAD files - select the file.



Here you can choose one or the other function: Keppel .... Ignore or ...... Both have their advantages, but it depends on who does what, so you should try and tinker with it.



Then open Layer - layer.

Description of functions:

Final depth - the depth of engraving - minus the value

Feed Rate - The speed of engraving

Plunge Rate - the rate dug into the material

Rapid height - the height of the moving material

After entering the values ​​followed by the generation of G-code and sent to Machu Picchu - transmission is possible only if the previous file was closed in Machu.


Table for sending file for milling should look like this.

Before sending it helps to have the coordinates zeroed - shift manually move into position and then reset.

Slow speed manual shift can be set in the diagnostics window - Jog function. Recommends a rate that can be easily adjusted to the zero axis "Z" with papers.



After sending the file to the moss just hit Cycle Start and the product is produced. After some time, now you can go for coffee.

When the product will not be repeated G-code using save: Edit G-code

This is a version of Mach 1.9 ... I recommend beginners to get acquainted with the functions and buttons názvamy and then switch to newer versions:

Here below is a sample of the latest version, which is the basic version comes free of Mach, but it is possible to buy so-called. Lazy Cam for - which is a complete CAM programs and, in addition to routing, in addition, outputs and functions of polystyrene and plasma cutting.

I will give him even more.
