hello  everybody. I am happy that such a website exists.
 

To sum up, I make a drawing (in mm - metric) and export it using HPGL.

I then use  the  Lazycam section  to import the  HPGL  file to generate a G-code. But
when engraving, the size of the result is totally different.


Is there a parameter I must change? I changed  the "scale drawing" in the
left LAZYCAM menue. The best result is with Xdimension « «6 » but  seems to  depends of the ratio X/Y. How can I be sure I engrave the same drawing I made? ( Same
dimensions)...

How  to  be sure mm's is  slected in the lazycam file auto-clean button options. ? What parameters should I change to modify that?
Is  there  a  manual  for  the lazycam ?

Note : I run under Mach3 R2.0.009, Lazycam 2.66



Thank you very much for your help in advance.

Best  regards.

Fred.

Hi fred,

can you export DXF from your drawing package.

I think HPGL is scaled to fit on your printer page, you may have an option to export in 1:1 scale this may cure your problem.

Thank you very much Graham!

I am now on  the road for 1 week. As soon  as I am back, I try this good idea.
But if someone else has another good idea...

One question : I  will not  have  this problem with a DXF file?

If so, I can just choose  a converter  to  tansform  my  HPGL or JPEG or  BPM files  into  DXF  ones?

Thanks  again for  your  precious  help.

Best.

Fred
