Mike, Assuming you are using steppers...
First you need to know how many threads per inch your lead screws are for each axis. The manufacturer should be able to get you this info, or perhaps Google. Each axis could be different. Next you need to know how many steps per revolution for each motor. Typically it is 200, but it could be something else. Then you can calculate the number of steps to move one inch for each axis. Next decide if you are using micro stepping or not for each axis. 1/2 microstepping = multiply steps per inch by 2. Once you have those figures we can tell you how to configure EMC2. My recommendation is to no bother wasting time guessing any of the numbers, but to find out for sure. I found the easiest way to reverse motor direction was to swap the 'A' and 'a' wires to the motor (8 wire bipolar). I'm not sure if this is an option available for every motor type, but it should be possible by swapping some of the wires. You might want to post with which kind of motors you have (number of wires, unipolar or bipolar). Andy [EMAIL PROTECTED] wrote: >> Gene Heskett wrote: >> >>> A bit rough on an obvious newbie, John.
