Printer model keeps disappearing

Tue Oct 27, 2015 9:06 am


I've created .STL file with model of print bed for my UM2 printer.

when I import the model via: Tool->Options->Machine->Printer Models->Add->printer_bed.STL everything seems to work great, but when I exit the program (or even sometimes when I prepare the print and then exit the preview) the bed model disappears.

How do I "save" the model to be always visible?
The .STL file is always on the same location.

Thank you!

That's probably because many of the profiles have the <printerModelOverride> option enabled, which essentially allows you to automatically switch to a new printer model when you load a new profile. A very neat feature. So you just need to set that up for your profile.

The link below explains how to do it. You essentially just export the profile and add 2 lines to it, save it, and re-import.

Add these lines:

Thank you so much!

Below I quote the full process of setting up custom print bed.

I would also like to add a simple solution for positioning the bed model (this question occurred in the linked topic).
What I did was (in SolidWorks) to create a new coordinate system and positioned it the same way as origin in S3D, then I saved the .stl with the new origin. It imports in S3D perfectly.

You would want to put the file into the folder:


Then go into Simplify3D and go to File-->Export FFF Profile. Then open that file up with a text editor.

Find the two lines:


Change those to:


Where myPrintModel.stl would be the name of your file.

Then save it, and go to File-->Import FFF Profile.
Thanks again.

This thread solved the issue for me, but for the benefit of users on a mac, you will need to put your STL in the following directory:

~/Library/Application Support/Simplify3D/

(Open a finder window, then menu "Go" - "Go to folder", then enter the above path in the dialog and click ok.

Are you sure about the Mac path? Looks like I have ~/Library/Application Support/Simplify3D/S3D-Software

Can fixing this please be made a priority? If we import an STL through the menu all of this should be set and associated with the machine settings automatically.

I agree; a hack should not be necessary. Fix this, please.

Well, 2018 and this is still not fixed. Congratulations!
Also I have problems applying the "hack" on 4.0.1 - could there be a problem with this workaround in 4.0.1?

Works fine for me. You're just editing the profile, so it isn't really a hack.

If you don't want any printer model displayed anytime you use the profile, then just open your profile in a text editor and change these lines


If you DO want a specific printer model to be displayed, then change it to this:


They just save and re-import the profile into the software.
