Lua script "access denied"

[Anonymous]

Hello,

I am running an instance of Netfabb Ultimate on my PC, and trying to run some of the example Lua scripts. However whenever I try to run a script, an error message (screenshot attached) appears, which says:

"LUA Runtime Error: [string "lua"]: 1 : Access denied

It is unclear to me why this error is happening, has anyone run into this before?

Thanks,

Drew

Hello, @Anonymous,

Welcome to the Netfabb Forum!

Are you performing any file I/O access? If so, could you share the respective lines?

Alternatively, if you do not wish to disclose any code publicly, feel free to submit a support case and attach the script there.

Best regards,

Steffen

Hi Steffen,

I do not believe I am performing any I/O, and I am also not running any custom Lua code. I am attempting to run existing built-in Lua scripts such as "Pack Tray" or "Generate Support". The same error shows up for any script I attempt to run. I also tried to run an example script from the Examples folder - "Script17_LabelMeshes.lua", but it did not work.

I have installed Lua on my machine and set the Path so that I can open a Lua prompt in CMD (I thought perhaps that could be an issue), but no luck still. Any ideas on what might be the problem?

Thanks,

Drew

Hi Drew,

Netfabb does not require a separate Lua installation. In fact, you cannot run Lua scripts in an external interpreter to control Netfabb; you have to run any scripts through the Netfabb GUI. To run a Lua script in Netfabb, you must import it first into the library, it cannot be run directly as an external file.

The built-in scripts such as Adv. Packing 2 as available through the DemoApplication GUI, however, do reside as files in the installation folder of Netfabb and are called during runtime of the DemoApplication script itself. The DemoApplication script contains a hardcoded path to these separate files. Assuming from your description that this is a default, unmodified installation, I can only guess that your Windows user account does not have the required file system privileges to access the required file.

Has Netfabb been installed by, say, IT and are you logged in as a regular user, perchance?

Best regards,

Steffen

Hello,

Running the application in as an administrator solved the issue. Thanks!
