 +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 machineYou 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. 
 +{{:process_guide:vcarve_pin.jpg?direct&275 |}} 
 +{{ :process_guide:vcarve_toolpaths-2.JPG|}} 
 +== 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. 
-You may end up with many unconnected vectors.+Tips: 
 +Small bits carving aluminium get pushed around during pockets so that you end up with a ‘V’ shape/slope in profileSolution: 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
-It's better if there are as few toolpaths as possible. You can join disconnected vectors by using the **"Join open vectors"** buttons.+Save Gcode (select all)
