Ho Jon, I've changed the subject line to be more relevant and corrected the gravity value. Now we have 1703 In/Sec^2 for maximum possible acceleration given the load and torque ratings. On my system in imperial units I have 2.5 inches/second and I randomly picked the accel as 3x that. Does that mean I could set MAX_ACCEL to say 1700 and get away with that or is that number abnormally high? I know I can try it but I'd like to know if the math is accurate. MAX_VELOCITY = 2.5 MAX_ACCELERATION = 7.5 What I'm trying to do with this tool is to take out some of the guesswork or the accidental divide instead of multiply. And second question. If someone is using metric units for their system what units are used to describe MAX_VELOCITY and ACCEL? Is it mm/minute? Or mm/second? Or meters/second? Is the weight specified in grams or kg? I want to be able to make the checkbox convert the imperial < = > metric correctly.
Thanks John Dammeyer
