My collets are 'manual', meaning that I have to re-zero the tool every time I change tools. Only when I tried drilling did this happen. When doing 2.5D milling, I didn't seem to have this problem. The 'safe/move fast distance is 25mm, so I guess that's where the 25mm comes from. Then, when I actually run it on the machine, the machine moves an additional 25mm (i.e. If I zero my Z coordinates to the top of the work piece and generate gcode, the gcode adds 25mm to the coordinates (I have no idea why). I created a simple part and tried using the CNC to drill holes.

I am trying to verify the operation of my CNC machine. I am generating my gcode using Solidworks CAM and using Drufel for post processing.

I switched out the controller to a NVSUM USB controller and a TB6600 cloned stepper driver. Easily set up the sequence of events for functions such as start and end of tape, tool changes, rapid motions, linear motions, circular motions, canned cycles, etc.I am using a modified Chinese 3040 5-axis CNC machine.Similar controls can be configured using a copy of a customized template.Pre-defined defaults for common types of CNC Controls to minimize the configuration necessary.Parameters on the Posting tab in the Machining Parameters dialog box.The CNC Code (G-code) that is generated when a part is post processed in SOLIDWORKS CAM® or CAMWorks®.The CNC code that is generated can be optimized for your facility's machines and production methods. The Universal Post Generator allows to you to customize post processors for both basic and complex code generation requirements and supports a variety of CNC machines and controls. The flexible, easy-to-use graphical interface of the Universal Post Generator or UPG is designed so users can quickly customize post processors to generate edit-free code for their machining environment.

Each post processor is designed to generate quality CNC code that meets the requirements of the machine control. SOLIDWORKS CAM® and CAMWorks® use a post processor to convert virtual information and toolpaths into machine tool specific CNC code (often called G-code) required for CNC machining.
