RE: [SherlineCNC] 4axis Milling and going from Solidworks to Mach3
- -I am happy with my step motors, though I understand that you can get superior performance with Servos. They are a bit more complex to install and to tune, also.
-A "post-processor" is something that is invoked by(or contained in) your CAM software. CAM software is what is used to go from a drawing or solid model of a part, to the machine code that Mach uses to actually make the part. There will be different post-processors for different machines. Think of it as the piece that translates the machine or part code into the specific language that your machine needs.
-I can't speak about cost-effective 3D CAM software. The only one I have any experience with is CNC Toolkit plugin, which works with 3DS MAX, Design Max, GMAX and Autodesk Viz. I have fooled around with it a little bit, but not gotten very far with it.

Subject: [SherlineCNC] 4axis Milling and going from Solidworks to Mach3
I am going to get a Sherline Mill package 2010 with the 4th axis turntable, with mounts installed ready for stepper or servo motors. I wish to learn about 4 axis CNC milling and as a hobby, cut out my own turbine blades to make wren turbines. I was wondering if you could please help me with the following:
* Should I spend the extra money and get servo motors or just stick with the stepper motors? Is there any real problem with overshoot or drifting?
* What is a "Post Processor" is that Mach3?
* I have Solidworks 2009 student version that I wish to create 3D model and to cut them out with the 4-axis mill. What is the most cost effective way to take a model from Solidworks and into Mach3?
