Mach3 Turn
« on: December 01, 2012, 07:12:29 PM »
I am hoping for a "poor mans" Turret.
Let me give an example :
As in mill we would home X, Z and A (Home The Rotary Table (A)  At 0)
We would then write.
G18 G20 G40 G80 G95 (Normal Heading Etc.)
A30 (Tool 1 Position By Advancing The Table To 30 Deg.)
T101 (Get Tool Offset)
G00 X 1.5 Z.1
G01 Z -.75 F.02
G00 X 1.75
Z.1
A90 (Tool Position 2 By Advancing The Table To 90 Deg.)
T202 ( Get Tool Offset)
We keep the rotary table going in the same direction so we have no lash.
We could have a tool every 60 Degrees.
I need to know how to add a DRO window for "A" on the turn screen.
Is this possible ?
Thank You very much,
JR

As a matter of fact ......
If I could just get the rotary table to work with hot keys and by writing the "A" in a "Turn" program  I would be happy.
I really don't need a DRO to tell me where it is.
Now, the table works in "Mill" with "page up page down" and writing the "A".
I need it to work in "turn"

Personally I would write the movements into the M6start macro, that way when you called a tool it would move the "turret" and apply the offsets at the same time.
Only concern I would have is do you have a way to lock the rotary axis as the cutting forces may want to move it.
You can easily add a DRO by using one of the screen designers available (Screen4 or MachScreen)

 :) Personally I wish I had the knowledge to do exactly what you said, but I do not. I suppose I could take the time to learn etc.
It is not possible to move a 72 to 1 worm with lash out and forces pushing against the contact area. An experiment was conducted: The
repeatability was within .0003 in 200 rotations going 360 degrees in 60 degree increments.
I wish to do the project the way I wrote the example. Is there a way to get the table to work in "Turn"? Is there a link to tutorial ? To a video ?

FYI 
I used the mill screen to run the experiment. It works fine but it is not convenient.
I work at TAIG TOOLS, This is a pet prototype project of mine.

The table should move just fine in Turn by using the A command from MDI or code.
If its not then attach your xml and I will have a look.

Thats my problem  :(
The stepper gets power, I can go to the mill screen and it works great using page up/down and "A" in MDI/G code.
I've copied all the setups from Mill to Turn. The stepper gets power upon hitting reset but the page up/down and MDI/G are ineffective.
It appears I'll have to take the time to learn what I need to learn so we can get this project off the ground.
We at the company think this will be one of our best products  :)

Ok, as said attach your xml and I will have a look as it should work fine.
If you want to go down the road of doing it in the macro so that it works automatically when you call a tool number  then  I could write that for you. As you are only needing to command moves then it should be very simple and only take me a few mins.

Link to a lathe screen done by Phil which has the A axis and see the file how to add it to MachTurn. Use the 24lathe set.

The lathe works perfectly !
"Hood" worked with me for hours. Made a screenset, wrote a .m1s, did a little of this and a little of that and the results were AMAZING !
I quickly wrote a three tool program and it worked with absolute precision. I could not be happier with my 12 tool CNC lathe.

He embraced my novice skill level and refused to quit until it worked. He would make a great president of the United States.
