part support

[GoogleCodeExporter]

   Hi, 

   I wonder if it would be possible to add a function that would permit to
have a frame support with two hole reference and that would permit to
reverse the part on the CNC in order to work on the two side as here
(http://www.vectric.com/WebSite/Vectric/cut3d/images/Bowl_small.jpg)

What version of the product are you using? On what operating system?
Heekscnc 0.11 with Ubuntu

Please provide any additional information below.

I sometimes wish we had a place to add a comment for the beginning of the 
GCode.  It
could include such items as how we expect the workpiece to be located with 
respect to
the bit etc.

I have also seen this issue with the Inlay operation where two halves of the 
same
function need to be machined separately.  In this case I have mirrored the 'male
half' about either the X or Y axis to separate out the GCode but it's not an 
ideal
solution.

My problem is that I can't imagine how this would work in practice.  Do you 
have any
ideas?

Heeks cnc already has that part support. It's tags. Just need some polishing 
(to alow
to place it at requested position).

But what you ask is some kind of 4th axis support. And we all like to have it.
It's basic indexer operation. As near all the stock is rectangular we can 
simulate
indexer at 0,90,180,270 degres. It's very desired thing. But not so easy to be
implemented.

I wish to machine blades from wood for small windmils (up to 1m diameter). It's
problematic as is machined in both sides. The one solution is the ability of 4th
axis. Then with the folowing sequence we can do the part:

1. Install the stock in machine 
2. Surface stock to known thicknes
3. Machime holes for alignment pins
4. Do the cnc operation on the top face and leave some tags and supports! (I 
realize
that tags are just not enougth the support 'legs' is needed to or work will 
bend)
3. Flip stock 180 degres around Y axis - actualy 4'th axis indexer move by 
hand. The
predriled holes just fit onto alignment pins on machine.
4. do the cnc operation on other side. But tags must be in same place or the 
part wil
start to hang out in some point.

All that can be done manualy but is little tedious and very easy to introduce 
some
error. 

I don't know if heeksCNC is able to do that. But I very like it if it can.

I have used the tag option for 2D profile cuts but have not seen a tag option 
for the 3D Zig Zag operation. Is there a possibility of having that 
incorperated.

I am using Heekscnc 0.17.2
