Major mistake in Creatr 2.1 behavior in corner

I made an observation, that Creatr does very bad job in certain corners: It's difficult to describe by words, I believe my pictures tell it all. As a result, the item come very weak form its corner

Well you are not quite right it is not something specific to the Creatr software. You need to check and see that it applies to other slicers as well.

See the attached picture from Simplify 3D

Hi! First of all, I didn't say that's specific to Creatr. If some other software fails similarly, it doesn't mean Creatr is OK. Look at the 64,7KB picture I attached (in opening message). Do you agree that the lower image is wrong way to build the items and the upper one is the right way? Secondly, I'm not sure how the object in the picture you sent is really about to be build (i.e will the tower be build on the top of top surface or on the top of the infill (like Created appears to build). Can you please deliver next layer(s) of the build. Meanwhile I'll check how does Cura or Slic3r build it...
Ok, tested with Cura and Slic3r... Slic3r clearly does build the right way: It starts to build the tower on the top of solid material, not on the top of infill (infil = 10% in the Slic3r and Cura pictures). Cura's preview quality is poor, but to me it seems like Cura also builds the right way. And these are freeware (vs. Creatr and Simplify3D)...
Hello,.. I did this perimeter check in Simplify3d. And only the first inner perimeter is place on the infill. The rest of the perimeters are correctly placed on the "solid" top layer. So I do agree that the Creatr software does this the wrong way (I have both Simplify3d and Creatr 2.1). And not only for the reason of resulting in a less stronger part, but also for the risk of leaving possible top_layer gaps exposed (created by a top layer not fully supported by underlying infill on edges). I included a screenshot and for the purpose of making it more clear, I did set a large coast distance. (stops extruding before end of perimeter) I do have to add, that I haven't looked at possible settings that may fix this in Creatr 2.1 yet. So maybe support can have a look at this?
Thanks for your answer! Interesting. In my example (opening message) all the yellow the perimeter lines are clearly built on top of infill (the red, outermost perimeter line _may_ be built on top of solid). You can verify this counting the lines on the top surface and compare layers 33 and 34. I've made this clearer in attached pictures. Also, if you look very carefully at the yellow "tower perimeter" lines of layer 34, you can see the cyan color in between the yellow lines which also indicates that there is infill (and not solid) under these lines.
I have a top view of layers 33 and 34 here, I guess they tell it all: Tower is built over infill. No good...
I already found your first pictures very clear ;-) And as I said, i do agree with you that is not the way it should be done. I just wanted to check if Simplify3D had the same issue, but as described, it doesn't. Tomorrow I will check if I can find a setting in Creatr 2.1 that might be responsible for this.
Oh, I read your first post too quickly (and too late in the evening) and thought that you got slightly better results with Creatr, but it was Simplify3D in question... BTW, there are also a plenty of other flaws and shortages in Creatr 2.1, but they are worth a different post...
I did some testing with different settings in Creatr 2.1. I cannot find any setting that fix this issue. So I also urgently request for a software update! Because when printing functional parts with this slicing strategy will result in very weak parts! For now I suggest using the “StripeSquares” infill instead of “stripes” within the build strategy to at least get better bounding between the infill and perimeter. Can Leapfrog support please react on this issue? (Or someone from Materialise)
Jouko Lehtomäki - Could you post your STL file please?
Sure. Attached.
I was curious if KISSlicer would do it correctly. It appears that it does. I own Simplify 3D also, but usually use KISSlicer.

Quick Start Guide

Installation clips
The following 3 clips will guide you through the installation process of your CreatrXL. By following these, you will be printing within 30 minutes. First start with unpacking the printer. Clickhere to see how you correctly pick up the printer

Part 1 of 3: Unpacking your CreatrXL

In this clip, you will be guided through the unpacking of a brand new CreatrXL. The unboxing along with the location of tie wraps which need to be removed are shown, as well as the process of a connecting the cables to the printer and computer.

Part 2 of 3: Software and configuration

In this clip, we will show you how to install the required software. The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the Repetier Host Leapfrog software or that controlls your 3D printer. We have tried to make this as simple as possible and also provided direct downloading links per operating system.

If you are using the new Simplify 3D software you can follow all the steps except for the Repetier-Host Leapfrog installation and using explanation. Simply download the software via the purchase link and before first use a pop-up will appear showing you the Simplify 3D Quick start guide. You can also download the Quick start guide or access it from the software via help –> Quick start guide. The quick start guide will briefly explain the functions of the software so that you can start your first print.

Please select you operating system and follow the descriptions in the movie.

Operating systemWindows

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the newest version of the Repetier Host Leapfrog software as shown in the clip. This software allows you to convert your 3D software file [STL for example] to a printable file [G-Code] and allows you to control your printer. The Repetier Host Leapfrog software contains standard CreatrXL Print Profiles. Just select the extruder, the filament material as well as the color and Repetier will automatically select the ideal print temperature providing you the best print quality possible. There is also a Leapfrog support button implemented in the software. A Mac version will be available soon.

If you have followed the installation procedure, but you can’t control your Leapfrog CreatrXL and the “6 commands waiting” message in Repetier-Host Leapfrog won’t disappear, you have to install the 2.8.28 drivers. Please see Solution can’t connect 6 commands waiting in Repetier-Host Leapfrog how to do so.

For a more thorough description of Slic3s settings please check this guide!

Windows 8
To install the Arduino drivers on a computer with Windows 8 follow these steps after downloading the Arduino software.

- Save unsaved work and write the instructions down
[your computer will reboot into startup options screen]
- Press the Windows Key and the ‘R’ key simultaneously
- Copy the command inside the brackets
–>[ shutdown.exe /r /o /f /t 00 ] – Select ‘Troubleshoot’
- Select ‘Advanced options’
- Select ‘Startup Settings’
- Select ‘Disable Driver Signature Enforcement’
- Install driver as usual via device manager


In this clip, we will explain you how you can generate a STL file using Sketchup. We show you what to download and how to export your design in STL.

Part 3 of 3: Making your first print!

In this final clip, the process of creating your first print will be explained. This starts with removing the callibration print that is already on the print bed. How to insert the filament and operate the Repetier Host Leapfrog software is also shown, which should culminate in your first 3D Print on the CreatrXL!

Google sketchupHow to export STL files from Sketchup

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. You will then need to in stall this driver for OSX to recognize the hardware.

The next step is to download the Repetier software as shown in the clip. This software allows you to convert your 3D software file [STL for example] to a printable file [G-Code] and allows you to control your printer. We have developed standard print profiles for the CreatrXL. Please follow the instructions below to install the print profiles for Mac [not yet included in the video]:

- Download This file
- Go to your Home Folder on Mac and select “Go to Folder” from the Go Menu en type “Library/Application Support/Slic3r/” - Unzip the file you just downloaded and dump the contents in the Slic3r folder, it will replace your existing settings. If you want to keep your current settings as well, take the contents from each folder and put this in the same folder in the Home/Libaray/App../Slic3r folder.
