G-Code, CAD, and CAM discussions / Re: procedure for reworking a work piece
« on: November 28, 2012, 01:07:27 PM »
SO you wanted to be a machinist huh. Doing a reset is part of the gig.

Remount your piece then touch off to the inside of the hole then set an XY value to that point NOW you have a datum point to position your new holes based on the OLD hole.

VB and the development of wizards / Re: Any new WIZARD ideas to work on ???
« on: November 27, 2012, 05:21:28 PM »
Just a note when cutting on a lathe you normally turn into the spindle not away from it. SO with your approach it would be backwards ??

Backlash is normally not a problem in turn as you normally only cut in one direction, into the spindle.

Here is your chance to be a WIZARD writer. I guess you have noticed there are FEW of them (Writers).

With any of the free ones you can look at the code and modify as needed. (;-)

Not sure IF any one noticed BUT the G28.1 Z.500 routine will NOW run with G68 active.   I found it by accident today testing some old code on the latest dev version.

Thanks Brian and Company (;-),

Also the wizards copyright rights belong to the specific authors of the work.  Modifying them without permission would be really bad form.

Just a thought, (;-) TP

Adding backlash comp in wizards is WELL beyond the scope of a wizard (;-)

You cannot cut an arc outside of the xyz planes MACH3 cannot do it. So everything has to be converted to line segments to cut arcs in the A axis.

Most modern controllers can do that on the fly. They convert the code from say Y to A on the fly. You just have to define the radius of the part in A axis.

Most cams can do that as well.

That wizard has always been a bit weird . You have to remember that in that wizard no matter WHERE you set the 0,0 it will always START at the top left of the material.

You set the tool diam and it SHOULD offset everything based on the offset.  Also double check your approach value THAT can also add to the offsetting in X.

IT really COULD use a rebuild to make it conforms to normal conventions.

You need to turn OFF soft limts to be able to use the largest envelope possible to surface your spoil board.

General Mach Discussion / Re: Mach3 and Tapmatic Tapping Head
« on: November 27, 2012, 01:40:12 PM »
OK Ill ask one more time WHAT is causing the tap to snap?  Is it bottoming out ? XY moving before it clears the top ?? , or what???   

The G85 is a boring cycle. Z down then Z up at feedrate. It does not have the fast retract in the cycle.

IF you want to try it it is described in the MACH3 manual.

The G95(Ipr) is to make your life simpler. IF you want to hand calculate the feedrate then use G94 (FPM)

General Mach Discussion / Re: block delete control
« on: November 27, 2012, 01:15:19 PM »
Fred there is no such call in mach3.  The only thing for block delete is the slash and it is just an ignore line command. ALL  lines that have it are ignored.

A single M99 call in mach3 gets you an error "Return in effect without a sub call " as there is nothing to return to(M98).

NOW CAN it be done ??  SURE it can.  There are examples on this site.
