Nest Liner Only

[Chris K]

I cannot get "Nest Insulation Only" to do such it nests steel also.

I picked one gauge of galvanized 28 and changed it to Machine Cybermation
I picked one insulation and changed it to Machine Water-Jet

In processes Nest Liner only, Nest for machine "Water-Jet Only*(Cybermation Post Processor)"
Other choices are Cybermation (Cybermation Post processor)

In machine setup Water-jet is in under installed machines with the Cybermation Steel cutting machines (I noticed this is a group Liner maybe it needs to be moved to that group?)

In the Water-Jet setup under under controller I am using Cybermation Post Processor

Any Help would be appreciated
Thanks Chris

Piggybacking on Chris K's post hoping to bump it to the top.  I am having this issue as well.

Two machines are installed, a plasma for metal and a waterjet for liner, both PPI Post Processors.  When I run the Metal Nest (which is set up to use the plasma), I get metal nests for plasma and nothing else.  All the pieces show that only half of their parts have been nested, as I would expect.  But, when I run the Liner Nest (which is set up to use the WaterJet), I get nests for both metal and liner for the waterjet.  This happens whether I run the Metal Nest first or not.

I cannot figure this out.  I even removed the metal materials from the tool setup in the waterjet's machine setup, but it just warns me they're missing and nests metal to the waterjet anyway.

Any help would be appreciated.  TIA!

We don't have a problem nesting insulation for a MAJ file with single wall duct.  Therefore, we don't need to nest the insulation only for single wall duct.  We only need to do this for double wall duct.

Based on my memory, we needed to do the following things in order to ask CAMduct to nest the insulation only.  That is for nesting the insulation material for a MAJ file that has double wall duct:

1.  We make a copy of the MAJ file and use the copy only for nesting insulation.  Leave the original MAJ file for nesting the metal parts.

2.  In the MAJ file for nesting insulation only, we change the double wall duct into single wall duct.  Thus, avoiding the trigger that cause problem with nesting insulation for double wall duct.

3.  Change the metal of the parts to a dummy metal material to prevent the metal parts from being nested.

This is best to do the step-2 and step-3 in a CAMduct script.

The dummy metal material is a copy of an existing material (such as Galvanized) and then rename it Dummy and get rid of ALL the entries from "Duct" page in the dummy material.

Hope this helps someone.

jaysomlam,

Thank you for the response!

So just to make sure I understand, if you don't do an insulation-only nest for single-wall duct, how do you nest your metal and insulation in single-wall duct to separate Installed Machines?  Or do you nest the insulation for your single-wall duct using the same Installed Machine as you do for the metal of your single-wall duct?

Honestly, I am not the guy who setup the machines in CAMduct (I created scripts).  If I understand this correctly, we created multiple machines in CAMduct (let say one machine for metal, another machine for insulation), and we assigned different file extension to the CNC files for each machine (to avoid a problem when we delete sheets).  Thats' how we use one MAJ file and nest both metal parts and insulation parts in the MAJ file.

We don't have a problem nesting single wall duct with or without insulation.  We used to have a problem nesting double wall duct until we worked around this problem by using 2 MAJ files.  We still don't know why we cannot nest everything using one MAJ file for double wall duct.  But we have the workaround and we stick with this and don't want to spend too much time trying to get to the bottom of the problem.

Hope this helps.

We do the same with file extension. We have .NC for metal machine and .VNC for our Vicon Waterjet insulation cutter. We us one MAJ for unlined and SW lined.  Or 2 MAJ for DW duct.

We Nest Only for the metal first, then the Nest Liner Only for the insulation.

CAM will always lay the metal flat if metal is available... you can only enable or disable insulation developments.
You can also restrict your liners to the liner table (installed machine) within your system, and then run it all at once.
Once NC is written, your liner files should have the extension/nc for your liner table... If you set a nest for machine preference, I believe* that margin will apply to both metal and liner.
