General Mach Discussion / Another Newbie 4th axis problem
« on: November 14, 2011, 02:17:35 PM »
One year or so ago i purchased stepper motor package, i have been using the three axis x y z to date with no problems or failures using V carve pro and Mach3.

Several weeks ago i got the bug to set up a 4th axis, made 4 jaw chuck and live center with tailstock, activated the 4th drive with full steps of 200. the jaw chuck is direct drive w/ a flex coupling and several things don't add up!

 1. Getting full rotations on diameter with Simple Cylindrical Wrap  when drawing on 50% or half of the diameter. as seen on mach toolpath.
 
2. Setting full step, half,1/4, 1/8  does effect the rotations but still have the rotational thing of multiple rotations.

3. Wrapping around x or y in post processor in V carve.

4. Using radius for feed rate and A rotations enabled in mach and rotation diameter of .0001.

After cycle start x or y z crawl to a stand still when A axis is activated during machining operations.

 I have visited both mach and vector forums and at this point i am totally confused.


thanks in advance

General Mach Discussion / newbie confused

Hi
This is my first post, I have been evaluating Mach3 for several months now and have completed my 3 axis table. I thought that I had things worked out but some rather strange things are happining.

I am at this point trying to cut .050 deep and using a small g code of less than 250 lines to make sure that everything is OK.

Problem is that when cutting I get nothing but garbage.... seems that mach has a mind of its own wandering around the Axis, when running code in off line mode (air cutting or simulation) everything seems OK.

Does Mach3  not let you run code with the evaluation software??

Sorry for the dumb Question
