If the computer gets overloaded by Mach3 or by running other software(s) in the background may leads to a lagging of the G-code code execution to even a falter in the motion interpolation which may lead to a catastrophic failure of some applications.Īnother problem with the LPT port is that in today's informatic technology this kind of port is no more used and is a dying out device and non of the new laptops having this kind of port built in anymore. As the output signals frequency gets higher with using todays more and more advanced motor control electronics Mach3 needs the more processor time of the computer. Windows is not a realtime operating system and therefor it is a difficult and CPU time consuming task for Mach3 to generate these signals in a precise manner. Mach3 in default working the the computer's parallel (printer) port and sending all signals via this port. Mach3 is a popular CNC machine tool control software running on desktop computers and laptops under Windows operating system.
