User may input an offset for both walls and floors. Default is 0 for both values. Value entered as either a percentage of tool diameter, or an absolute distance. Users may input plunge angle value in degrees. An increase in plunge angle corresponds with a decrease in machining time. Value should not exceed 30 degrees, and must be appropriate for stock material. Harder materials require smaller plunge angle. Enable "Machine Passes only at Final Depth" if pocket depth relative to adjacent geometry is equal to or less than the tool flute length.

Toggle between Left and Right depending on whether the tool should offset outside or inside the assigned chains. Turn off compensation if the assigned chains are intended as cut centerlines.

Enable if operation is intended for roughing, disable otherwise. Enable for small parts when vacuum hold down is used. Enable for all parts when mechanical hold down is used. User may select Automatic or Manual tab placement. Automatic works well for most situations, with minimum 4 tabs recommended.

Once operations have been chosen, geometry has been assigned, and parameters have been adjusted, the next step is to generate toolpaths. Toolpaths are visualized in the modeling space as Blue and Yellow lines that are drawn across the input geometry. Select the operation s that is are being used, then g enerate the selected operation by clicking , or regenerate all dirty operations by clicking.

Complex or corrupted geometry may cause toolpath generation to fail. In this situation, the problem geometry should be deleted from MasterCAM a prompt will warn the user that any operations that reference the problem geometry will be affected. The geometry can then be edited or recreated in Rhino, exported as a new.

Excessive toolpath generation times can sometimes be reduced by changing Visibility from Shaded to Wireframe. Trimmed surfaces with far-flung control points cause trouble when merged into MasterCAM. Sometimes these problems can be averted by running a few Rhino commands on the problem surface s prior to merging:.

Large, complex meshes and surfaces occasionally cause problems in MasterCAM as well, depending on how they were generated. This issue is usually solved by recreating the mesh or surface in Rhino or Grasshopper. The FabLab provides a sample Grasshopper script that should produce usable geometry from the original problem geometry. Grasshopper Script for Recreating Geometry.

In most cases, MasterCAM will not automatically generate the toolpath for a selected operation after its parameters and geometry have been assigned.

If the operation lacks assigned geometry, or has had any changes made to the geometry assignment, parameters, or tool definitions, then the operation is considered "dirty" and the toolpath icon will instead display. The toolpaths for a dirty operation will disappear from the modeling space until regenerated. If an attempt to verify dirty operations is made, MasterCAM will prompt the user to regenerate with a pop-up dialogue.

Verification using dirty operations is inaccurate and should be avoided. Verification aka Simulation is the process of playing out the generated toolpaths in a virtual environment in order to check for errors and omissions.

Successful verification accurate stock and tool definitions, no collisions found is a necessary pre-requisite to performing any real CNC machining at the GSD. Student submitted jobs will not be approved or scheduled until successful verification is demonstrated. Select all operations that have been configured and will be used. Operations will be verified in chronological order according to their order in the Toolpath Manager. Click verify selected operations in the Toolpath Manager to open the Mastercam Simulator window.

I think I found an article or perhaps youTube video about it seems like a very long time ago, lol. Unfortunately, I can't even refresh my failing memory because I don't have the software anymore, but I think it was all done through the standard SW drop down menus.

Sorry I can't be more help If you poke around you should find it pretty straightforward to make the basic edits. Complex customization is another matter entirely, you'd need an expert for that. Re: Mach3 post for mastercam I have a used CR onsrud router myself. I think that would get me pretty close. I am a little new at cnc but I do have a technical background. Re: Mach3 post for mastercam Hi Steve and Michael.

I have a Cr Onsrud router with a Osai controller The machine has a fixed that would be close gantry and tool changer. I was looking to use mastercam for cad cam. My machine has 4 axis and i need one that is suitable for it. Does anyone here know any post? PS: it needs to be for mastercam. I can't change the soft. If not, please help me get some working with 4 axis, it's really urgent, like for a week job. I am learning Post editing, but won't have time to learn everything.
