In this essay we are going to tell we how to modify 3D indication into a genuine indication that we might cut with we CNC appurtenance or laser cutter.
Let’s make this Christmas tree
Slicing of a indication for CNC machining regulating a piece material.
Run 3ds max.
To equivocate a dimensions units difficulty use millimeters. Go to a Customize Units Setup in a menu. In a Display Unit Scale section of a non-stop Units Setup dialog box, name a Metric button and name millimeters from a drop-down list. Click a System Unit Setup button. In a non-stop window name millimeters. Click Ok.
Import of a model
Click a focus symbol and name Import.
Select a required record and click Open.
Depending on a record extension, a window with settings will appear.
When importing from STL, in a Import STL File dialog box in a Weld Vertices section, name a Quick Weld switch. This will severely accelerate a import.
Сheck a indication for a surfaces intersection.
Select a indication and make it unclouded by dire Alt + x.
On a front perspective emanate a territory Create Shapes Section
The surfaces intersections are good seen now.
Delete a intersections.
Select a fir-tree image.
Convert a indication to Editable poly by right clicking a perspective window (Convert to Editable Poly).
By clicking a 5 pivotal go to a mode of a elements selection. Select a case of a tree and click Detach in a Edit geometry toolbar.
Do a same with a star. Now we have 3 apart objects.
Combine them regulating a boolean operation.
Select a fur-tree and Create Compound ProBoolean
In a Parameters of a toolbar switch to Union.
Click Start Picking. Select a star. Once again click Start Picking to finish a intent selection.
Now a indication does not have intersecting surfaces.
Bring a indication to a distance we need, so that a tallness becomes 10 cm.
Create a box Create Standard primitives Box.
In a toolbar Parameters set a Height at 100 mm
Click a R pivotal to name a Scale tool. Adjust a distance of a fur-tree so that it touches a tip craft of a box.
Slice a model.
Set a grid spacing equal to a covering thickness. Right-click a Snaps toggle button. In a Grid and Snap Setting dialog window find a Home Grid tab, and set a Grid Spacing at 4mm; In a Snaps tab check a Grid Points checkbox.
To capacitate bindings, left click a Snaps toggle button. The symbol gleams blue.
Create a territory in a front perspective Create Shapes Section. On a tip perspective place a territory craft in front of a model. Move a craft one block to a indication and click a Create Shape button. In a Modify tab of a toolbar change a craft one by one block by clicking Create Shape until we have finished a whole model.
You will get something like this:
Hide a fur-tree. Select a ensuing curves and request a Extrude modifier to them.
Delete a additional outlines.
Select one covering and click Editable Spline in a modifiers. Click a 3 pivotal to change to a spline preference mode. Delete a additional outlines.
Save a outlines for a G-code generation.
Select all a layers and undo a Extrude modifier. To do it right click in a modifier smoke-stack and name Delete in a context menu.
Position all a outlines in one plane, get them together and hang in a support 160х160 mm.
Export a outlines to DXF.
Select all a outlines and click a focus symbol Export Export Selected. In a Save as form choose AutoCAD (*.DXF). The trade parameters leave as default.
For G-code era use Inkscape (https://inkscape.org/ru/download/)
and JTP Laser Tool. (https://jtechphotonics.com/?page_id=1980)
As Inkscape doesn’t support DXF, modify it to SVG regulating a giveaway online use https://www.dxfconverter.org
Run Inkscape. Set mm as dimensions units.
Import your outlines.
It is probable to drag a SVG record to a Inkscape canvas. To see a outlines set their density larger than 0, during 0,1 mm for example.
To move a distance of a outlines to a genuine ones emanate a rectangle identical in distance to a support around a outlines, i.e 160x160mm. Now scale a support with a outlines so that a support coincides with a rectangle. Remove a support and a rectangle.
Now beget a G-code.
Go to Extensions Generate Laser Gcode JTech Photonics Laser Tool.
Laser ON Command, Laser OFF Command; Travel Speed is a speed with a laser off; Laser Speed is a speed with a laser on; Laser Power (255 corresponds to 100% of a power); Power On Delay is a check of a laser start; Passes is a series of a laser passes; Pass Depth is a laser downshifting after any pass.
Specify in a Catalogue where to save a G-code to.
To start a G-code era click Apply. Shortly we will see a G-code record there.
Hope that we enjoyed this guidance.
