System Requirements:

  • 486-66 PC or better with math coprocessor
  • DOS or DOS base operating system (or WIN 3.1, 95/98)
  • Available parallel port for IO


  • Fully configurable step/direction or direct phase outputs - compatible with MaxNC (not the closed loop type) and HobbyCNC boards, Geckodrives, and all types of Camtronics drives
  • Canonical RS-274D g-code - works with CAM programs such as DeskEngrave, VectorCAM, ACE converter and others
  • Built-in code editor - stop and re-start anywhere in a program
  • Unlimited file sizes
  • 8 axis simultaneous motion, any mix of angular or linear with backlash compensation and straight IPM/IPR and inverse feed modes.  
  • Configurable IO for reversible and speed control spindles, E-Stop, home, limit, block hold, coolant pumps, clamps, digitizing probe, jog encoders, and PLC's
  • Fully parametric programming, with variables, subroutines, and expressions
  • Linear, circular, and helical interpolation using IJ or R notation
  • Multiple axis threading capability - tapered and multi-start threads.
  • Turning, threading, drilling, and slab-milling canned cycles
  • G54 through G59 fixture offsets
  • 60 tool offsets

NOTE: Direct port access is not permitted under Windows NT, 2000, and XP, and so the proper function of TurboCNC with these operating systems is not a given.  Instructions on how to set up these systems with a boot disk is included in the program documentation.

Source code and free support is yours when you register this program for $60 US. See the ordering page for details.
