Re: FFF file location?

Fri May 19, 2017 9:48 am

Hope this is usefull to some of you. Worked for me but try at your own risk.

My win10 installation crashed irrevocably after an automatic update (..grrr Microsoft) and along with every other program and settings (data was on separate drive) I lost my painfully configured FFF settings for my three custom built printers. No backup of those....

So this is what I did.
Installed a brand new ssd for the freshly installed Win10. Left the old disk untouched with the bricked system on it for the moment.
(thanks to NEUTRON16 whose istructions I followed :https://www.sevenforums.com/general-dis ... stall.html)
(But as long as you still have access to the old drive or a Registry backup either of those would work)

Since Simplify stores it's settings in the registry I thought it could work for me as well:

Press Start obr - type REGEDIT, open it.
Open HKEY_LOCAL_MACHINE, then File - Load HIVE.
Browse your old hard drive DISK:\Users\%USERNAME%\, highlight file
NTUSER.DAT and open it.
That is HKEY_CURRENT_USER of your old Windows.
It will ask you for a Key Name, enter 123test

Now you will see that HKEY_LOCAL_MACHINE has got a new thread - 123test.
That is actually old registry mounted.
Go to 123test\Software\simplify3d, right click Export. (give it a name and save to any location)
Then click head thread 123test, and File - Unload Hive.

Open exported reg file in NOTEPAD. Edit - Replace, replace all
save that reg file and run it.

This process reloaded all my FFF profiles!!! and all seems to work fine.

Its been awhile for this thread but it needs to be revisited. WHERE ARE THE PROFILES?
When we upgrade to a new S3D the profiles are there in the new version this seems to indicate since older versions are retained that the profiles are saved somewhere. Yet when my iMac recently died and I restored my apps from my backup... no profiles.
So... are the profiles saved as resources within the app package? If so why didn't they come over in the restore???

This is for a Windows machine, I do not have a solution for any other operating system.

I know this is an old post but it didn't have a solution. I was messing around and found some other posts talking about this registry location, again not marked as a solution to backing up Simplify3D settings or migrating between systems, so here it is. First off if you don't understand what comes next then you probably don't want to mess around with this because if you mess up the registry then you can mess up your machine. You want to open the registry editor, find this key HKEY_CURRENT_USER\Software\Simplify3D and export it. Then just merge to your system after bare metal restore or to another system.

Simplify3D is storing the profiles.ff in the registry!!!! Isn't this some kind of standards violation?

while lot of slicers store profiles in .ini or similar files (usually \users\{username}\appdata\{local|roaming}\{progname}\.. storing config & profiles in registry is not any type of "violation"

I doubt they will ever change this, but I hope at least they will do the "export/import" function of all profiles and app config
gcodestat integrates with Simplify3D and allow you to
Calculate print time accurately (acceleration, max speed, junction deviation all taken into consideration)
Embed M117 codes into G-Code
Upload your G-Code directly to Octoprint
open source and unlicence

I have over 150 fff files because I work in a specialized lab. We need to create a new simplify access point and to do so we have to export these fff files individually. This is time consuming, tedious and costs us money to do so. It would be best if all fff files could be exported at one time. However, if Simplify saved the fff files in a designated folder somewhere it would make it easier to copy that folder for back ups and re-installs. it would also allow one to address name changes more efficiently and set the profiles to load alphabetically.
If anyone knows how this can be done now that would be beneficial.

The FFF settings are stored in the registry.

Open the Registry Editor and then go to the HKEY_CURRENT_USER\Software directory and copy the Simplify3D folder and all sub-keys.

I made a tool to export all or selected Profiles in separate FFF Files in one directory including automatic numbering. You can download my tool from

Hope it will help you
