Title: 4th Axis help on MAXNC10CL
Post by: charliev on February 22, 2007, 09:09:44 PM: Hello all,
Can anyone give a newbie some general help regarding a 4th Axis rotary table for a MAXNC10CL?

I'm trying to wrap my head around the way a round surface is milled. For instance, rotating the same number of steps or degree will yield different "distances" upon the surface of the rod depending on the diameter... so what does the G code look like for this?

Any milling tips or reference material would be appreciated.

Thanks,
-charlie

In the Settings window there is a Rotation Diameters section, Enter work Diameter for your axis there, helps Mach control F-speed.

Still need to set rot. axis in steps per degree of rotation, One full turn divided by 360 = steps per deg.

My steps per deg are 400.2, vel 2500, acl. 500, 10 micro step comtrol 144000 one full turn sherline rotary table.

Hope this Helps, Chip

It looks like a Mach2 screen you posted, Brett posted a Mach3 screen.

I was refereeing to Mach3 Settings Page in my post also.

Both will co-exist and run fine, I have very little experience with Mach2.

Thanks, Chip

Post by: charliev on February 23, 2007, 12:26:43 AM: Interesting... everything says MACH3, and I DL'd MACH3. I'll be purchasing shortly as I wanted to check it out first. Maybe this will get fixed with my purchase (?)

I appreciate these posts.

I have a design that is basically layed out as a plate... I need to traspose it to the surface of the tube. Such that the width of the plate is the circumfrance of the tube... (if the plate were tied end-to-end, you'd have the tube) I have all the coords of the plate that need to be cut on the surface of the tube... this is where I'm a lttle stumped - if I have to express in degrees (?)

Am I making any sense?

Yes your making sense

Look under Help "About Mach" it will tell you what Version your using Could be an eariler ver. of Mach3.

You can use one turn "Steps" and work it that way also, just not sure about the cut-speed you'll get though.

Depends on the reduction ratio of your rotary table.

Post your code, find out what ver. of Mack your using.

Thanks, Chip

Chip,

400.2 steps per degree x 360 degrees is 144072, yet you indicate the full turn is 144000. I can only assume the 400.2 is correct, but how do you arrive at that? How would I be able to confirm steps per degree on my table?

(Thanks for all your help)

One full turn of your table divided by 360 will give you steps per deg, the 144000 is off a typo. sorry.

PM your Phone # i'l give you a call if in US.

Thanks, chip
