Creatr HS Underextrusion

The first few layers of my prints always seem to underextrude (including the skirt). Please see the pictures. I have tried lowering the print speed, overextruding but nothing seems to improve the matter.

The underextrusion starts to improve after the first couple of layers but I've had a couple of prints where it simply stopped extruding after the 20th layer and the extruder kept moving as if it was actually printing.

Any idea on how to regulate the flow of the filament?


I increased the flow rate to 130% in Simplify3D in the Machine Control Panel. It has improved the results substantially but I'm still having problems where the flow is inconsistent. The extruder stopped extruding mid-way through the print (even though the nozzle kept moving according to the gcode). Also you can see gap lines in the print and one of them was large enough to break my unfinished print into two pieces just as I was removing it from the build plate.

I just found out why my machine did this. my nozzle holes are too big. so I adjusted new diameter in the software and it works great again.

@marc do you mean the nozzles are larger than .35mm? What diameter did you use?

yes mine are larger. i didnt notice because I "cleaned" them too much so the bottom wore off and made a bigger hole. they were 0.35. now they are 1mm.. I need new nozzles.

 

@marc that's a huge increase! how did you find that out? how long have you been using the nozzles for?

when no settings whatsoever would work anymore I removed the nozzles to check if they were clogged or something, then I saw the big hole.. I have the printer 1 week :) .. Do not clean the nozzles with a file!

 

Hello, Your printer can stop extruding because under the extruder settings you have got a retract setting with directly underneath a number with a small negative setting. This setting makes that after retracting, the filament will be pushed the retraction rate minus that small negative number to compensate for oozing. If that small negative number is too large it can happen that with a lot of retractions your filament is completely sucked into your nozzle due to overcompensation. Making this setting a smaller negative number or zero will remove your problem. Furthermore, i found that instead of increasing the flow rate lowering the first layer to a much smaller number like 20% can help. Also increasing the extrusion multiplier helps.

Thanks Marcel. Making the negative number 0 worked. I'll try the rest of the tips.

hi 

Is your problem solved?

i have the same problem as you

I figured out a few problems and now it works OK: 

1) use new nozzle, the diameter must be unaltered ( exact size!) 

2) measure the filament diameter always! and use correct value, this make a huge difference, I have many rolls and they vary extremely! up to 0.2mm ! 

an here some settings I use: 

no cooling fan, I only get bad results when cooling, similar to your photo.

temperature, speed and layer thickness influence each other. try to find the right relation one to another. I find especially speed is a major factor, why I don't understand the HS, because high speed is impractical...( may work a bit faster for PLA, but nothing else)

I will probably limit myself to 2 brands: faberdashery is great! and colorfabb.

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.

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.

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


Mac

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.
