LazyCam (Beta) / Re: Relocating the 0,0 origin.
« on: December 06, 2010, 11:10:43 AM »
I tried that and when I right click the origin it doesn’t move. If I click on it (left click) then I can relocated it to a new place but as I said before it takes the new position coordinates. When I right click on it an option window is shown:  “Delete Selected Items”, “Join two selected Primitives”, ”Load shape file to screen”, “Save chain as Shapefile” and “Remove shapes”.  Thanks.

Yeah, you are right, but if I could do what he did I’ll manage to do what I wanted do. All what I wanted to do is to call the piece’s center point 0,0 That’s all.  I am probably asking too much but that's the way the west was made.

I found the posting that I was referred in my first post.  http://www.machsupport.com/forum/index.php/topic,13262.0.html  This member had the same problem I am facing now and he found a solution.  I have try to duplicate his approach and couldn’t.  It could be that he uses a different version of LC than the one I am using. Thanks.

Mr. Rich, my apologies if I express wrong. I am very grateful to you and the rest of you who has tried to help me. Please understand this is not my native language and I am making an effort to convey to all of you what I wanted to do in my best way. I am sorry.

OK, I reloaded the DXF file on AutoCad and cleaned the drawing, sent it to LC and relocate the origin at the center and sent the .tap to TKcnc editor and converted the XY to polar coordinates The polar listing was not in order, so I when back to LC and relocated the origin to the beginning of the cuts instead and back to TK still no good. I am posting the two files so you can have an idea what’s happening. It’s imperative that the rotary table turns only in one direction always. If we can find a solution to this method a script could be writing later on to do this process automatically or at least more practical.

Ok, I think I understood the concept. I am going to ignore my reasoning and stick to yours.  Today I’ll start a test from the beginning and I’ll report the results shortly. Thanks to all of you.

Thank  you docltf and overloaded. I’ll try that. The reason for having the center of the piece at o,o is because all the points around the center should be related to it.  I will cut the piece in a rotary table using only A , X and the Z axes. So I most convert all the XY coordinates into polar coordinates. If I don’t have all the points relates to the center 0,0 then the polar points will be back and forward and that is a disaster on a rotary table cuts. When ever you jump from 30 deg to 29 deg the plate will turns 359 deg to get back to 29 deg. That’s happens every time the angles are not in an order sequence. I am using the rotary table because in that way I am expanding my machine cuts capability. My Y axis is only 5” and my X axis is 19”. So using this method I can cut in theory pieces of 38” diameter. The real limitation is the mill’s throat. Thanks.

Yes, I do. I probably do not explain my self well.  That file was only an example of what I am trying to do. With AutoCad I generate a drawing with the origin at the center of the piece and exported it as a DXF 12 to LC. Assuming that LC will show the origin point at 0,0  as the original DXF drawing has it. Well no, LC shows the origin point (0,0) at the lower left corner. Then I moved it to the center where I want the origin point to be and it takes the coordinates of that center point (-2.295, -1.888). I need the center of the piece be origin 0,0.  Thanks.

Yes I have.  I can move the origin but it changes its coordinates to the new position where its placed. I need it to be 0,0,0 at the new position.

Here it's the file.
Before I posted the problem I did some searching within LC postings and found a member that wanted to do the same as me, transfer the origin 0,0,0 to the center of his drawing and he could do it just by resetting the origin. When I do that the origin goes to the lower left corner with the minx, miny coordinates instead of asking for new coordinates. Also I have tried to right click on the origin but I got a complete different window that he got. I am using LC 3.00.2 and I have tried also ver. 2.02 and 3.00.1 with the same results. Without relocating the origin 0,0,0 to the center of the drawing I can’t continue the preparation of the cuts. Thank you in advance for your time and interest.
