I am exporting a DFX file from AutoCad14 as DXF 12 into LC taking a good care that the origin at AutoCad is where I wanted and at 0,0,0. I checked the "loading options" at LazyCam and check mark the As drawn box so the origin keeps in it's place. Doesn't happens, the origin at LC is at the corner of the drawing and if I relocate it were it should be there is no way that I can change it to 0,0. I have tried to change the MinX and MinY of that point and its impossible! There is something that I am overlooking or don't know how. I am sure that somebody had this problem before. Please give me a hand. Thanks

Never had the problem you described. Please post your dxf file.

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.

have you tried left click hold down move with mouse for move of origin.

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.

maybe i do not exactly understand what you want to do.i downloaded your file and brought it into l-cam.origin is located bottom  left.
moved the origin to center with mouse.checked the two chains and the x0 y0 is centered to the drawing.if you did the code from that point
it would machine the part based on setting the tool to the center of the stock.is that what you would like to do,set x0 y0 to center of stock?

bill

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.

Tim

really dont know what to tell you.when i do it i get x-1.7103 and x1.7104

try uninstall of L-cam do a reboot then reinstall.

Hi Tim,
  When you move the origin to the center of the job in LC, the X and Y coordinates shown are for LC to know the displacement from the drawing to the NEW selected origin.
  Just select the center as the new origin, then post to Mach, set your work/part coords to the center of the stock and you should be good to go.
Works this way here.

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.
