Makerbot Desktop - Staff can't send to 3D printer

[robyholmes]

Hi All,

 

I have a very odd issue at a school I support. They have a MakerBot Replicator 2 and use the MakerBot Desktop software to run it. The issue we're having is since updating their servers and folder direction setup staff (And I should think Students) have been unable to send jobs to the printer. The software can see the printer but when you click on 'Print' it opens up the loading bar window but doesn't progress.

 

However if we login as a network admin, it works fine. So this made me wonder if admin rights where needed but when I granted a test staff account local admin rights it still failed.

 

So I'm thinking its some windows policy but I'm not sure where to start. We don't redirect AppData so that remains local, the STL file they are trying to print is on a USB stick which as write permissions etc. I had file screen on the file server but putting it in passive mode made no difference. The program doesn't show an error either it just never loads the file on to the printer.

 

I've also updated the software to V3.10 which is the latest version supported on this printer.

 

The major change which took place over summer was changing folder redirection away from %HOMEDRIVE% to \\UNC-PATH so I'm thinking it could be this but really not sure why?

 

Has anyone come across this? I'm hoping I don't need to go down the trail and error route of changing policies to find the cause.

 

Thanks, Rob

Using Procmon you should be able to see what it's trying to access and go from there:

I forgot I did run this but couldn't see anything being blocked or unable to write. I might need to run it again as it was quite late on a night so might have missed something.

what happens if you put the file you want to print on the local hdd rather than in a redirected folder?

Its currently on a USB pen so is basically local already. Both working and non working accounts are using the same files (Tried multiple) from the USB pen.

 

My current thinking is it doesn't splice the file until you click 'Print'. So it needs somewhere to store the gcode file when it splices it. This is the bit its getting stuck on but while it would be blocked and why I wouldn't be able to see it on process monitor I don't know. Maybe it see's its using a UNC path and doesn't even try to create it? But why wouldn't it then error.
