-** ~~ THESE INSTRUCTIONS ARE UNFINISHED ~~ **

- 
-VCarve is the supported software for use with Swarf-O-Mat. 
- 
-This software is installed on the computers available in the computer room in the space. 
- 
-Artifactory members can make a folder on the network that can be accessed by Swarf-O-Mat. 
- 
-VCarve is kind of compatible with a range of vector formats but YMMV. 
- 
-==== Existing Tutorials ==== 
- 
-There are materials and video tutorials on how to use VCarve online. It's well worth checking these out. 
-

-==== VCarve Local Spe ==== 
- 
-We recommend going through the official instructions and tutorials thoroughly. 
- 
-There are some speficica 
- 
-== Open VCarve == 
- 
-If you're using the computers in the computer room there should be a link  on the desktop.

-== Create new VCarve project == 
- 
-"Create new project", there is a link on the left hand side.

- 
-== Set the dimensions of your new VCarve project == 
- 
-{{:process_guide:swarf-o-mat_new-bar.jpg?direct&300 |}}Take care here.  
- 
-It is important that you have a good visualisation of what your project will look like such as: 
- 
- * the dimensions of base material 
- * how your project will be carved out 
- 
-**Size/Material** 
- 
-Specify the material you will be using 
- 
-Make sure the piece will fit comfortably within the material with enough of a border that you can clamp down and prevent the work from moving. 
- 
-  * Width(x): 440mm 
-  * Height(y): 580mm 
-  * Thickness(z): 60mm 
- 
-(Actual machine area: 460x600x70, but need to allow space to affix job.) 
- 
-**XY Position** 
- 
-This can be set to whatever, though local convention is to leave it to default.  
- 
-That is to leave set it to: **bottom left**

- 
-Congratulations! You now have a blank bit of material. 
- 
-You can now arrange your job on the material and draw the **toolpaths** for your job.  
- 
-These paths are **vectors** and map out the route that the Swarf-O-Mat will take to cut out your job. 
- 
- 
-{{:process_guide:vcarve_vectors-draw.jpg |}} 
-{{ :process_guide:vcarve_vectors-close.jpg|}} 
- 
-The **"Create Vectors"** are the main tools you will use to draw your project. 
- 
-Make sure all the shapes are closed vectors (there are a couple of ‘join’ options, eg: select two lines, press [j] or by using the **"Join open vectors"** buttons.) 
- 
-Useful: [N] for Node edit 
- 
-What you need to be thinking while you are creating your project is **what path is the cutting tool taking?** 
- 
-Are there multiple cuts? Are you cutting **on** the line as opposed to inside or outside the vector line? Are you cutting all the way through? 
- 
- 
-**NOTE:** usually do you NOT cut from the edge of your material using a milling machine. You usually place your job in the middle of a piece of material so you have **ample room to clamp your material to the milling machine deck**. Bear this in mind while drawing the necessary vectors on your material. 
- 
-Once you are confident you have drawn a logical cutting path for your whole job you need to specify this path to VCarve using `Toolpaths` -- the right hand side pop-out options menu.

- 
- 
-Toolpaths 
- 
-Make a toolpath for each logical cut your job makes.  
- 
-For example, if you were making a bas-relief of a particular size you would use 2 toolpaths: 
- 
- ~ one toolpath to cut out the job from the material\\ 
- ~ one toolpath to engrave the material 
- 
-There are several cutting options. The most commonly used are: 
- 
-[profile] cuts out a shape; \\ 
-[pocket] removes a pocket of material; \\ 
-[drill hole] drills a hole (!) 
- 
-You need to create each path individually. Try and think through your job so that you can put the paths in logical order. 
- 
-(Note: you can use the `pin` in the top right hand corner to stop this toolbar from popping closed.) 
- 
-{{ :process_guide:vcarve_toolpaths-bit.JPG|}} 
-When you first create a path you need to set certain options. 
- 
-**Cutting Depths** -- You should know how deep you require the cut to be. 
- 
-If you are actually cutting a piece out add a bit so that you can be sure it cuts all the way through (eg for 3mm thick material you would set this to 3.2mm to cut all the way through **BUT YOU MUST ADD BUFFER MATERIAL UNDERNEATH YOUR JOB IN THIS CASE**).  
- 
-Obviously if you are creating a pocket or engraving you set the depth of the engraving (eg 1mm deep writing in 3mm thick material). 
- 
-**Tool** -- if you are not familiar with bits **PLEASE SEEK ADVICE ABOUT THIS** so you can know what is the most appropriate bit for your job. 
- 
-(Passes are calculated automatically) 
- 
-**Machine Vectors** -- you will hopefully have a good idea of what is the best vector for your job. 
- 
- 
-If you are entirely cutting out one piece from another (a very common usage) use 'tabs' to keep your work steady.  
- 
-VCarve tends to put them in weird places, particularly corners -- move them to appropriate positions (out of awkward corners, evenly spaced). Eg: for Jarrah decking: tabs 5mm long, 3mm thick. 
- 
- 
-Tips: 
-Small bits carving aluminium get pushed around during pockets so that you end up with a ‘V’ shape/slope in profile. Solution: 2 tool paths: profile, then pocket. 
-Skot’s favourite tool for jarrah and ply: 6mm end mill 
-3mm passes 
-24,000 rpm (slight risk of burning jarrah); acrylic: 12,000 rpm for not melting 
-feed rate: 1300mm/min 
-plunge rate: 600mm/min 
-ramp plunge moves [√ ] 
-safe Z = clearance above the wood and clamps
