Possible Lazy Cam Bug
« on: March 21, 2008, 05:23:36 PM »
I am new to CNC, Mach3 and LCAM. With lots of help from this forum I have things going. I am cutting signs to learn how everthing works. I laid out a sign in Coreldraw X4. exported it in a DFX file ( autocad 14 format, Corel skips autocad 12 for some reason). Loaded it into Lcam. The wording in the sign is " Robert Cowert" but in L-Cam  both "e" are missing the "-" so it looks closer to " Robcrt Cowcrt". They are not  "C"  the tails are almost touching so they are "e" without the horizontal bars.  What am I doing wrong? If you open the DFX file with Corel, everthing is fine.  Is this a bug in L-Cam or am i doing somthing wrong. I am attching both the DFX and Lcam files. Maybe one of you old hands can enlighten me.

Thanks in  advance.
Mike

Hi, Mike

Your corel dxf export is dropping some lines, When I loaded it in BobCad it missed some more lines.

Replaced the text with BobCad ver. 22 text below.

Hope this Helps, Chip

Chip:

Thanks again for your help. At least I know it's not Lazy cam. What I don't understand ( not that I know much) is how it can drop that part of the "e" when I export the file but when I open the file with corel its there. Is there some other program I can view DFX files with ? Have you ever seen a program drop lines like this ?

Thanks

Hi, Mike

I loaded it into 3 different Cad's, All had issues.

Try to export in different dxf file types from your corel program.

Check the wed for free dxf viewer's or cad programs

Thanks, Chip

Chip:

I downloaded a viewer, and I clearly see the dang compleate "e" with it. If i reopen the  dfx file with corel it's there also.

 If I place just one really big e in the dfx file,the only program that I have that wont see the complete "e" is Lazy Cam !   I dont understand how that can be.   It's crazy.  I wonder if the font has some type of code that cam programs dont like.

Thanks for the input

Try exploding the DXF file 4 or 5 times. Then load into Lazy Cam.

Mr.MIKE

      what corel does to a drawing in the way it handles it i have no idea. but you are not the first one to run into this with corel. they are saving the file to a version of dxf that is not = to autocad ver 12.
      I downloaded you dxf and opened it in l-cam 3.00.2 to see what you were talking about-. did nothing to it,and closed it back up. then i opened it up in cambam the free beta ver, and all the eeeeeee's
      were there. somehow it can read the corel dxf. then i used the export function and saved as a differant file using cambam as a filter. opened it back up in l-cam and now everything is there. attached is
      the filtered file.

I see what  you mean. Big difference in size. And the"e"'s are there. I will find cambam and try it. Would anyone know what limitations Lcam has? I have  3.00.2 and I have a license for mach3. The one thing I noticed different  in the one that Chip fixed for me to try,  is that the Lcam one i did never had an entity # over 49

Ben:
I transformed it 500% and it made no diffrence. I guess transforming is the same as exploding the drawing.

thanks for your time and help.

Hi, Mike

You need a LC lic. for Offsetting, Pocketing and Turn Features, Don't remember any other limitations.
