FLSun SR PrusaSlicer Profile

1 Setup

The FLSun SuperRacer is not official supported in the PrusaSlicer software. So we need add our own printer or use a similar to start with.

Let's go!

1.1 Initial printer setup

We start the PrusaSlicer and then from the “Configuration” menu the “Configuration Wizard”

In the Wizard step over until you reach “Other Vendors” and select FLSun. Press “Next”-button

You should then see the available FLSun printers, which are currently supported. We used the FLSun QQS Pro as the base to start the setup for our SR printer.

So press “Next2-button until you reach the ”Filaments". You can choose the filament settings you want. They are a good starting point for different types. Later, you normally setup the parameters for the filament you buy.

Last but not least you can step over with the “Next”-button or directly press the “Finish”-button if you do not want to setup or change anymore.

1.2 Adjust printer settings

Now that we have added a similar printer to PrusaSlicer, we can change the settings to fit more to the SuperRacer.

After you added the QQS Pro you can select the “FLSun QQS Pro” under the tab “Printer Settings” (see screenshot bellow)

Select this printer if it was not by default or after closing the “Configuartion Wizard”. Then we first adjsut the “Max print height”. On the Website of FLSun https://flsun3d.com/products/super-racer-sr we will see the print size with 260x260x330mm. So we set the height to 330

As soon as you change some values the PrusaSlicer recognize this and shows the printer name as “modified”. So now is the point to give it the right name. To do that press the small floppy disk to the right of the printer name.

In the now open windows you can change the printer name to waht ever you want. I use a meaningful for e. g. “FLSun SR” or if you have multiple of them “FLSun SR Office”

Et voilà ! 

So now you can start with it. If you want to do more on setup for e.g. adding a bed shape go on.

1.3 Change printer bed shape (Model and Texture)

1.3.1 Model

Downlod the STL from here and then copy the file to the PrusaSlicer installation folder under the profiles folder of FLSun directory for e.g. C:\Program Piles\Prusa3D\PrusaSlicer\resources\profiles\FLSun\

Then go to the printer we added to the PrusaSlicer in chapter 1.1/1.2.

Settings → Printer Settings → General → Bed shape → Set…

Load the Model (SR.stl) as the Model

1.3.2 Texture

For the texture you can choose an existing svg-file for e.g. the Q5 or QQSP one (Q5.svg, QQSP.svg), which should be already installed by default. Alternative texture files can be found here

or a PEI like one here

1.4 Custom G-Code

The G-Codes which are added at the beginnen as we choose the “FLSun QQS Pro” as the base for our setup…are OK. But we do not like how the prime line was drawn. So we changed the G-Code. To install them simple copy and paste the code bellow under the printer settings in “Custom G-Code”

REMARK: Using the published G-Codes are on your own risk!
