This document describes the setup of the machine, some of its dimensional limits, and some aspects of the process whereby an .NC file from MasterCAM is used. (It could use some significant improvements.)
Template Files
Below is an empty MasterCAM template files with a number of supported toolpaths included. The settings assume that 2" foam material is being used, so changes would be necessary for other material characteristics. Four tools are defined, if using a tool other than one included, a new tool will have to be defined. It is necessary that toolpaths using different tools be posted separately so that each tool can have a new Z calibrated on the machine between toolpaths.
Review the NC File
There are two post-processors that you can select in MasterCAM to output an NC file for the Roland Mill, we recommend using the "Fanuc 3X Mill" machine definition as there are problems and limitations related to the Roland machine definition and post.
Recommended: Fanuc Machine Definition and Post Processor
The files that are most up-to-date can be found on the computer connected to the Roland Mill.
The Fanuc 3 Axis Mill Machine Definition, Control, and Post Processor will output an .NC file. This .NC file should be reviewed for errors and needed corrections before it is run on the Roland Mill. Do this within MasterCAM's code editor.
- Check for the correct Spindle Speed and Feedrate for the tool.
- Check for Z0 and Z-, to prevent cutting into the machine table.
- Return to MasterCAM and make corrections there, if either of the above conditions need to be corrected.
Things to note:
- In the VPanel, users must set the 0,0,0 of the "G54" coordinate system before cutting the RML file.
- The NC file does contain the spindle speed as defined in MasterCAM for the tool/toolpath.
- Coordinates are displayed in inches.
- Drilling operations are supported.
- When aborting a job the machine will NOT automatically retract to a safe location: make sure you manually lift the tool up above the stock before resuming or starting a new job, etc.
- Toolchanges are not supported by the Roland MDX-40A. MCX files that use multiple tools must output the toolpaths for different tools separately and re-calibrate a new Z for each toolchange.
