Software overview

Software

Operating systems:
Windows XP
Vista (Not recommended)
Windows 7
  Minimum PC requirements:
1.4 GHz processor
1 GB Ram
USB 2 port

   

PC based CNC control
Designed voor usage with external USBCNC CPU.

The result is hickup-free motion with higher speeds.

Design your next part while USBCNC is doing its job.

Look Ahead feed calculates the optimum path, and delivers the best possible performance. Especially CAD/CAM generated programms consisting of small line pieces will benefit immensely. 

On the Real-time graphic display you can whatch what the machine is doing. The graphic screen also visualises the movement limits of the machine.

Operate scherm

The operate window. All machine operations take place from this window. In this window you can do everything mouse-less with function keys very quickly.


   

Program scherm

In the program screen, DXF and HPGL files can be imported.

 

Simple CAD/CAM functionality.

  • DXF
  • HPGL
  • Engraving
  • Drilling
  • Profiling/cutting
  • Pocket milling

   

 

Tool data for Tool-radius and Tool-length compensation, see G40, G41, G42, G43, G49.

For Lathe there is additional a tool X offset and a Tool orientation..

 

 

 Tools scherm

The Tools screen for milling. Tool data is entered here.


   

 Variable scherm

Variabele watch window. During test, the G-Code program can be single stepped and the variables can be watched here.

 

USBCNC has extended G-Code programming capabilities. During test/debug the variables can be watched while single stepping the programm.

  • # variables
  • Subroutines sub - endsub - gosub
  • While - endwhile
  • If - else - endif
  • Mathematical functions
  • User dialogs from the G-Code trough function "msgdlg". You can make your own wizzards with this.
  • Automatic tool change is aloso defined this way, direct in the G-Code macro file.

   
Simple setup
  • Choice of visible axes, x,y,z,a,b,c
  • Nr of steps/mm per axis.
  • Machine reach per axis
  • Max speed and Acceleration per axis
  • Homing speed, direction, position
  • Backlash compensation per axis.
  • Interpolation mode for A-axis: 4th axis milling, 4e as linear (Foam cutter), standard rotation axis.
  • Lookahead feed optimalisation angle.
  • IO modes and inversion.
  • Jog keys inversion for machines with moving bed.
  • PWM mode voor spindel speed control
  • Name of file to strore digitize data.
  • Password to prevent changes of the settings bij machine operators.
  • Handwheel parameters.
  • Favorite editor e.g. notepad++
