XproMill

XproMill is a CAD software application developed to work as a 3-axis CNC milling machine controller. The application converts G-Code commands to machine commands that are sent to the hardware card though parallel port.
It works only with CNC machines with stepper motors or servo motors with Pulse-Direction servo drives. The tool reads data from NC files and gives you the possibility to control a CNC milling machine.

User interface and main features

The GUI looks clean and implements several commands for helping you alter the feed rate and the X, Y and Z values. Plus, it gives you the possibility to analyze and monitor the milling work with the aid of a graph.
XproMill gives you the possibility to simulate your complete G-Code in your PC without the need for implementation of trial and error sessions. It offers support for real-time 3D graphics, 3D graphical G-Code simulation, color-coded G-Code lines, 3-axis simultaneous linear/circular interpolation, 4 quadrant circular interpolation, axis limits, ‘Emergency’ stop button, as well as soft limits for additional safety.

Software and motor configuration settings

XproMill comes with several software settings for helping you ignore unsupported G-Code, mirror XY in graphic view, skip G-Code error lines, specify the folder where NC files are stored, enter the number of segments in the drawing (recommended 7), set the current position at home, enter the home feed (fast and slow) and retract distance, as well as enable soft limits and specify them (X, Y, Z).
Additionally, you can switch to the default settings and set up a password for restricting access to software and motor configuration settings.
You can also tweak several motor parameters, namely start speed, maximum feed speed, maximum rapid speed, arc speed, ram steps and pulse width, as well as backlash and parallel port address.

Bottom line

All in all, XproMill comes with a decent feature pack for helping you make use of a 3-axis CNC milling machine controller, and is suitable for advanced users.
