I need some technical advice. A few months ago, wide horizontal ribs started appearing on my prints along with vibration-like patterns on the sides. -See pictures attached-
I've been tinkering with the settings on a basic level (acceleration, for example), even if I'm not entirely familiar with the whole set of G-codes for the Reprap/Marlin system, so I might have screwed something up. Now I'm stuck...
The code was generated in Cura with 20mm/s print speed, 0.15mm layer height and 95% flow rate to make the flaw stick out more.
XY acceleration is 1000mm/sˇ2 , Z is 250mm/sˇ2
Are yo talking bout the color variation in the printer, i.e. the horisontal lines, or is it the crappy corner?
The color variation could be uneven temperature in the hotend, I've had similar problems on a different brand printer.
the corners, I would say i related to flowrate and/or material. What type of material are you printing with?
Ok, then I have to ask if you left the PLA out in the open for a longer time?
Do you have a alternative material, like a new spool that has been stored in a sealed enclosure to do a comparing test with ?
I could very well be that what you see is related to moisture in the material, especially PLA will behave similar to this if it is left in the open for some time.
I have the same problem. Are the width of the horizontal bands the same regardless of the size of the part? It is in my case. That rules out anything that is time related (such as heat varying in the extrruder or bed) since if that were the case the bands would be closer together for parts that take longer to print. Are the width of the bands the same as the threads on the ball screws? My theory is that the root cause is Z-axis wobble. In other words the bed shifts around a little as it moves up and down. In the commercial machines (I've looked inside a Stratasys Fortus when it was being serviced) The bed is on large linear bearings. Of course that's one reason they are so expensive.
Actually, the notorious Z-axis wobble is what I fear the most... I'll do some further prints to check if these waves are of the same width.
In the first few months, if my memories are correct, vertical walls were perfectly straight. Is this wobble an unwanted "feature" or is it because of the stress endured while working?
Done... different material (ABS instead of PLA), an object twice the size of the previous one. Same 5mm ribs on sides 2 and 4, semingly fitting into each other. That looks like the wobble you mentioned.
-Does anybody know a way to correct this?
Just thought of something that can be worth checking. How is the tension of the X/Y/Z axis belts? Also, what about the linear bearings, are they running smooth?
I just realized that on our old printer, we had similar problems with irregular horizontal lines, in this case the printer had been in action for a while, without any actual maintenance.
We went over and tensioned the belts, lubed the bearings and calibrated, since then we haven't seen this issue.
Maybe worth checkin in to ?
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
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.
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.
SIMPLIFY 3D SOFTWARE
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.
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.

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.
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!
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.
