Hi all,
Ok, I have a few questions concerning the setup with the 4th axis. For the moment, I will be using this in a horizontal position to either cut gears and splines using the Wizards in Mach 3, or using the "Wrapper" program that is a slick little program that was made up by a user on the Vectric forum. This can be found here if you're interested:
http://www.vectric.com/forum/viewtopic.php?t=2920A few questions:
1- Looking through many forums, I have seen of users setting up their 4th axis steps different ways such as "Angular" or "Linear". Which do I choose for the programs I want to run? I would be thinking angular but not positive. Is this something that the user would change for certain jobs using the 4th axis?
2- My stepper is indeed a 200 step/ 1.8 degr. per step and it is set up for microstepping so that's 2000 steps/ 0.18 degr. per step, correct?
Which also means it's 144,000 steps per 360 rotation, correct?
Does this mean that by dividing 144,000 by 360 , I then put "400" into the steps per box for the A axis?
3- Any ideas on a slick way to check the actual backlash on a rotary table. By just putting an indicator on it, the "play" in the table is .0012" . Not too shabby but if you have any other ideas, please let me know -
Thanks as always-
Dave
