Calculate Step Size – this one is the preferred way of doing things.Measure it and divide 1000 by the length in inches. Move and Measure – slap a pen or marker on as a tool head and draw a 1000 step line.You will need to set this as accurately as possible if you want your machine to be accurate. This variable stores how many steps to take to move the X axis 1 inch. Parallel ports need to run in EPP mode for any of the parallel port control software.

NCPLOT CONVERT DXF SOFTWARE
Some people choose to write the g-code by hand, as well.Īnother type of CNC control software is available for specialized CNC hot-wire foam cutting machines.ĬNC Control Software (Machining/Milling/Lathe):ĮagleCAD– PCB schematic and board layout program with free trial version There are other more specialized g-code generating tools used for specific purposes, such as generating PCB isolation routing, generating a pattern of holes, or roughing out a pocket.
NCPLOT CONVERT DXF DRIVER
The breakout board splits these signals so that the step, direction, and enable lines for each axis are routed to each motor driver board. Our stepper motor driver kits make use of the parallel port signals.
NCPLOT CONVERT DXF SERIAL
This is usually done by reading and writing pins on the parallel port, but there are some motor controllers which can operate from serial or USB, as well. The CNC control software then reads the G-code and turns it into motion to drive your machine. Your CAD (Computer Aided Design) software ( wikipedia) is where you design your parts to be routed, lathed, milled, or cut.ĬAM (Computer Aided Manufacturing) software ( wikipedia) converts your CAD drawings into G-code, which is the programming language that the CNC control software understands. So, what software is involved in CNC? There are primarily three parts: you probably wouldn’t be here right now, would you? The experts out there may disagree, but if you had to be an expert to do this. The AXIS Graphical User Interface is second to none (IMHO).

TurboCNC is a great piece of software, if you don’t want to visualize your tool paths in real time and are comfortable in DOS.ĮMC2 is completely Open Source, free to use, and probably the most reliable, flexible, robust system out there. Mach3 has a HUGE support group and bypasses some of the timing issues of the Windows environment. We prefer EMC2 on Linux and Ubuntu, but there are others available for those who are shy. Couple the availability of low/no cost CNC control software, low-cost integrated circuitry, and the tons of high-end hardware now found on eBay: and for the first time in history, CNC is attainable to the hobby market. The fall-out of the DOT-COM bust has brought CNC to the hobbyist.
