UC100 USB CNC motion control to the Mach3 program

The Mach3 program can control the CNC machines through the printer port. Producing accurately timed signals through the printer port is quite a significant task on part of the operating system, and it has also limits (it is not recommendable to run other programs besides Mach3, for they can easily affect the "smoothness" of the emitted signals). There comes the question: how can it be avoided or substituted?

 

Especially in light of the fact that the printer port virtually disappears from computers, particularly from laptops with the advancement of tecnology. Several, commercially available solutions have been already unveiled to substitute the printer port. However, the solutions are relatively costly and their connection is complicated. UC100 is meant to solve this problem. It is only to be connected to the computer's USB port and the CNC motor driver circuit via the standard printer port. Mach3 handles the outputs (12) and inputs (5) of the CNC100 the same way as if we were using a printer port. It produces the output signals with high precision, and puffers it with a bit more of 1 second memory The production of hardware output signals takes a lot of work off the operation system, hence you can apply a lower-performance computer, too.
