WinPC-NC Light First steps
2. First steps
2.1. Requirements to hardware
WinPC-NC Light is able to control a connected CNC machine and
the corresponding drives directly by the LPT printer port. In order to
make this procedure possible, a real time driver has been installed in
the lowest plane of the operating system providing the necessary
timers and mechanisms.
A faultless operation is therefore only guaranteed with Personal
computers with certain minimum of requirements.
• modern CPU with at least 1GHz clocking frequency (more than
2 Ghz are recommended)
• Windows 2000 or Windows XP operating systems or successing
models
• at least one true parallel printer port (onboard or by ISA/PCI
plugin card)
• standard graphical card, keyboard, mouse, hard disk and other
common PC implements
Detailed information and tips for selecting the suitable computer can
be learned from further support information documents.
2.2. Possible restrictions during realtime operation
A reliable realtime operation under Windows depends on many
different factors and can be affected by many running actions.
Disturbances by other programs lead normally to an irregular and
rough motor run. Sometimes it can happen that the machine will act
completely uncontrolled.
