Several light duty bench top vertical milling machines have reached the market in the past few years but some CAM software fails to deliver their full potential.
This process is error prone, tedious and often results in the following two unfortunate outcomes: designs with few complexities in the z-dimension and a reluctance to change designs once g-code is created and validated. This instructable describes an approach used to arrive at g-code from STL files automatically, which often addresses these issues and enables users to achieve the full potential of their vertical milling machines.
The mount was chosen because it has non-trivial features in z, undercut features that require cutting from the top and bottom and features that cannot be reached at all. All of these features make it a good candidate for showing the capabilities of this approach.
The mount design was created in Design Spark Mechanical by intersecting a model of the foam with models of the other components including the case. The first step to generating tool paths is to understand how you will grip the stock and free the part.
The RPI mount includes flipping the stock in order to cut from the top and bottom. The stock is gripped using lateral wedges and the part is kept secured in the stock with tabs that are manually cut away after machining is finished.
Tab geometry is given in the form of an additional STL file referred to as scaffolding. As the STL file defines regions that make up the part and should therefore not be removed by the cutting tool, the scaffolding object defines additional regions that should not be removed. Precision requirements and trade-offs with performance should also be understood and decided upon.
Tool path creation-time and run-time typically increase with precision so the minimum acceptable precision is often used.
This decision is applied directly by stl2gcode algorithms and also indirectly as a function of tool selection. Smaller diameter tools can reach finer detailed geometry but require more passes to hog out open regions. Stl2gcode never removes stock that makes up the part; when a tool diameter is too large to allow the cutting tool to reach a feature, that feature will not be realized. This is most commonly observed at inside corners, which result in fillets.
In this way, stl2gcode does the best it can with the selected tool. The RPI mount was created using a max error of a few thousandths of an inch.
Using Stl2gcode to Automatically Generate G-Code From STL Files
Scaffolding objects define regions that should not be removed by the end mill in addition to those regions defined by the part itself. Just as scaffolding at a construction site facilitates working through large scale fabrication realities, scaffolding objects in stl2gcode facilitate working through the realities associated with machining operations. Scaffolding objects are typically designed alongside the parts to be machined and exported as binary stl files using the same process used to export the parts themselves.
The mount is secured in the stock with tabs until the machining is finished. In addition to cutting the battery feature, the bottom tool path cuts the perimeter of the mount except for the tabs. If the tabs were not present, the part would free before the stock could be flipped and gripped to cut the top features. The scaffolding object used to create the bottom tool path is the dark blue object in the above image [left]. As shown, there are six tabs connected by a perimeter feature.
The bright green object in the above image [right] is the scaffolding object used to create the top tool path. This keeps the top tool path from including perimeter components since these would be redundant with those in the bottom tool path.
The plans arrived at in "Step 1: Planning Approach" are applied via stl2gcode configuration files such as the one shown above. These files are broken into sections, which are controlled by the directives in the section and are responsible for a g-code file. Directives that are given outside of the sections apply to all of the sections. Directives are key-value pairs where the keys are separated from the values with either a space or colon.
File system paths can be specified with either forward or backward slashes and may include double quotes. Similarly, both sections use raspberry pi mount 1. This directive is set to The extra 20 thousands of an inch ensures that the cut reaches the entire way through the stock.
The default min height value of 0" is used for the top section, which specifies the bottom of the stock and top of the mill deck. Stl2gcode does not require any interaction with the user while it runs.Most of the time this is a function of a CAD program, but not always. There are a number of different software packages out that can serve as your Slicer, and most 3D Printers come with one program or another. These are not so useful for making 3D parts, but they are still very popular for CNC work because a lot that goes on can be represented in 2D.
The part is flat on the top and the bottom. There really are no interesting 3D features, it is the outline that makes the part and the outline is 2D. Here is a DXF outline of the same part:. Tip: Check our library for free DXF files that you can use in your designs. That depends on how you want to go about it. The process is pretty straightforward as this video showing that part being made with Cambam shows:.
A lot of that information has to do with the fact that even though the model is 2D, a 3D part must be made. For simple parts, this is not too hard. Extrusion is a pretty easy concept to grasp. Further, assume the space between the two is filled with solid material. The level of difficulty will be a function of which CAM software you choose. If you want to get started making some parts quickly, I always tell beginners to start with MeshCam. Having a lot of different toolpaths available is a two-edged sword.
On the one hand, it can help you pick out the path that is optimized for your job. Fortunately, most CAM software is available on a trial basis. Take advantage of it. If the CAD software is new too, then this is a good way to get more familiar with it. Next, sign up for 2 or 3 different CAM package trials. Try out your models with the CAM software. See which package is most intuitive for you to learn. Get an idea of which package has sufficient YouTube videos and user forums to help you on your learning quest.
Get something inexpensive and easy, like MeshCam, so you can make parts sooner. Plan to upgrade to a more full-featured package later, when the rest of your CNC skills are up to speed and you start feeling like your entry-level CAM package is holding you back. You may never quit using that super simple package though. I know of a number of machinists who keep two packages. Are you an artist who is trying to convert your designs from concepts to reality?
If any of these are true, you may want to be able to convert images into GCode rather than starting from CAD at all. CAD is great for parts that must have particular dimensions and particularly for parts that have lots of rectangles, round holes, and straight lines in them. But most CAD becomes painful in a hurry when smooth flowing shapes are called for Rhino3D being one exception that comes to mind.The Slic3r project has been under active and massive development.

Print with dual multiple extruders. Print beautiful colored objects, or use your secondary extruder to build support material.
Or put a larger nozzle on it and print a faster infill. Use brim for the best adhesion. This unique feature improves built plate adhesion by generating a base flange around your objects that you can easily remove after printing.
Microlayering: save time, increase accuracy. You can choose to print a thicker infill to benefit from low layer heights on perimeters and still keep your print time within a reasonable amount. Compose a plate but print one object at time. Use the built-in plating interface that allows to place objects with drag-and-drop, rotate and scale them, arrange everything as you like.
The sequential printing feature allows to print one complete object at time in a single print job. Cool cooling strategies. A very smart cooling logic will regulate your fan speed and print speed to ensure each layer has enough time to cool down before next one is laid on it.
