Hi Dam,

To send Polyboard DXF files for nesting you should use the Optinest post processor option:

Optinest-PP-010.jpgImage Enlarger

This options will export both faces of each part in one DXF file 

You should add a layer code that indicates the face of machining :

Optinest-PP-face-code.jpgImage Enlarger

The DXF files will now contain a layer that indicates the face of machining.

For double sided machining, export from Polyboard to Optinest and optimise.

Load the nesting DXF map file into Vcarve and set up double sided machining.

Like this you have the labels from Optinest and the double sided machining using Vcarve.

The only problem with this method is when using a tool template. Optinest will flip parts so that the most machined face is upper most. However this can be face 1 or face 2. So if using a template you must manually tweak the tool paths on the double sided parts.

Hope this is helpful.

Best regards,

Ness

Hi Dam,

Optinest doesn’t automatically handle double sided machining, but it’s possible to organise one’s work with Optinest to make this possible.

How you do double sided machining with Optinest depends on how you want to manage it and the CAM software you are using. 

There are 2 ways of managing double sided machining:

1- flip the whole sheet over before cutting parts

2- machine the second side after the parts are cut

For us to advise you correctly can you  give us more information on your CAM software and CNC machine?

Best regards,

Hi Ness,

I often use method 1 to machine the double sided parts.

In fact i can manage this issue by Vcarve but as my concerns in this topic that Vcarve cannot do labeling so i must think about Optinest. So that i must study how i can do double sided machining in Optinest. The parts imported to Optinest did not show double sided parts. It becomes 2 parts (each side per part).

I am using Vcarve as CAM software.

Thank you.

Great thanks.

IT worked.

About double sided machining, OPTINEST is not able to do this job, is that correct?

Thanks and best regards.

Hi Dam,

Double sided machiing can be handled 2 ways.

Once the parts machined on one side icut use the individual Polyboard part file to run the cnc to machine the second side.

Or, if using Vcarve separate code the DXF layers to have the machining face named. Machine one face of a complete sheet without cutting, flip the sheet and machine and cut the sheet from the second face.

To avoid Optinest thinking the grooves are outlines, set the dxf filter to only look for the correct outline layer.

To do this, go to Pieces>DXF import, load one DXf file and in the Outline and Inner Outline section type the name of the outline layer.

Tick the Tooling import box and then click Apply. The layers lists will be populated with the appropriate layers and the groove layers will be considered machining . This of course assumes that the the grooves have been set to a different layer than the outlines.

Hope this is helpful,

Best regards,

Hi Ness,
I tried to use Optinest but had 2 problems:
1. I cannot manage the double sided parts in Optinest.
2. When i did optimization, the software Optinest cannot understand the through grooves, so it will identify those grooves as a part and creats it to the optimized layout.

Are there any solutions for this?

Thanks.Nested.JPGImage Enlarger

Hi Dam,

Optinest will export the complete cutting map as a dxf file that can be loaded into Vcarve to be tool pathed. Vcarve  will then write the Gcode. If you use a tool path template, this is fully automatic and works very well.

Hi Ness,
I know that, but Optinest cannot make GCode and export to CNC machine for nesting, right?
Thank you.

Hi Dam,

Vcarve doesn’t produce labels.

You can use our nesting software Optinest that will print the labels and also manage stock and off cuts.

Hi Ness,
Are there any ways to creat label for the nested parts in Vcarve?
In the Chinese softwares, the label of each parts has the layout and that part is highlighted so it is easy to find the part to stick the label.

Can we do so on Vcarve or are there any other nesting software has similar function?

Thank you.
