E Z CNC is an old software program which communicates to your motor drives, through your PC parallel port (printer port), only under Windows 95/98. Since it is only capable to work under Windows 95/98, and is no longer supported, it is free for all to download . It may be used to produce step and direction pulses with ramping for up to 3 motors, senses 3 home switches, and the E-stop button for emergency situations. All signals to and from the port are (TTL), which is compatible with almost any driver/translator found today. Also pins to the parallel port can be configured to almost any desired configuration. Switches can be enabled or disabled, switched to negative or positive pulse by the click of a mouse button. This Software was designed for a beginner operator in controlling accurately and smoothly 3 axis simultaneously.
Version 6.20 release now with: Spindle control Aux 1, 2, 3 control for dust collection, cooling, Emergency stop input and a motor enable output. EZ CNC can control three-axis limit switchs and can automatically power-off after job is completed. Install Shield installation is 2.1MB.

Welcome to what I believe is a great site for the beginner CNC (computer numerically control) operator. This EZ-CNC application software is free for all to download and use. You will find it to be the most cost effective way to begin your journey into a three axis control, with accuracy, user friendliness all for Windows 95 /98. Beware that EZ-CNC will not operate with Windows greater than Win98 and is no longer supported has a product. So beside the fact your on your own with this, the Software will allows you to simulate movement, calculate estimated time , visualize your design and where you are in your run move, allows you to fully automate your control process and much more. EZ CNC software artificially strives to conform as closely as possible to a Real-Time performance, with ramping algorithms to provide smooth starts and stops, like found on high end hardware controlled devices.
