Title: Mach3 Turn
Post by: jr66 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.

Thankfully my name is not Richard ;)
Then again maybe I would be due a lot of money from all the spanners sold over the years under the name King Dick :-D

Rich, was just my attempt at a poor joke and had nothing to do with you and your name.
Often humour doesnt transcend border, in fact, often, it doesnt make sense other than in my warped mind :)

Hey Hood my friend,
Never even associated the reply to my name. Added a couple of smiley's to my post.  ;)

Now correct me if wrong. I always thought your first name was actualy Robin.
So if that's the case, unforunately, you will never be able to be King, since  it would be at odds 
with history.

You can't be a pres or a king cause they are too busy to play with Mach and that would make the king very unhappy. Nice thing you did helping this chap out but then you always help people, like a real "Robin Hood" a legal one, lol.

 "Poor Man's Turret CNC"
With the help of Hood this is the result. Also the tool wear offset has been changed so that
you make the part BIGGER by + tool wear, SMALLER by - tool wear (same as Okuma, Hass, etc.

Its good it is working as well as you had hoped, it is actually something I may consider doing for the wee lathe I have :)

I'll make refinements in the days to come.
It is important to say however that none of this would have been possible without your help and patients.
