Diver motor noise / behaviour

ABS is giving me a lot of problems.

It seems it's just not feeding the material.


in my other thread i already attached a picture showing the driver wheel being clogged by abs filament.


here is a video showing the wheel during printing.

the noise it makes (rattling) and the erratic movement during that rattling noise worries me.


the other driver (with PLA) doesn't have this behaviour


here's te video (noise starts at 0:10)

5 people have this problem

Hi, 


I have the same problem on both my extruder motors. 


I would say that it is a design flaw from Leapfrog, from my experience a bowden set up, or any extruder for that matter should be geared. This to handle acceleration, retract, speed etc. 


I'm not familiar yet with witch motor Leapfrog is using, but stepper motors are not meant for high torque, in general they handle speed and positioning better, ideally one should review the specs of the motor and adapt the gearing to the optimal torque/speed for that individual motor. This is something that should have been done on the design floor. 


Sure, one can tweak the current set up and end up with a ok result, but doing this I believe one narrows ones options, always compensating for a faulty design. 


Just my opinion, 

Hello!
Excuse me for my english. I'm not from Europe.


I have the same problem. After a lot of experimentation to find out what happens. When the perimeter of the model has a complex view of detail. Usually these are small rounding. At this point, the printer handles a lot of small teams with very short extrusion (E0, E0,0001 E0,0002 and so on). Support I have not answered it. But I think the problem in the printer. Can be a problem in the board, it may overheat ...

Try to simplify the model (make mesh reduction 0.08) and print again.
You please contact support?

thanks for your reply. I think you are absolutely right. I did sent the printer back because I had too many issues with it.

For now I will wait until 3D printers become more reliable.

I had the same problem, finally I discovered that the tube and nut that guides the filament is the problem that avoids that it goes to the extruder. It gets stacked and thats why the driver gear cannot push the filament (that is what provokes the craping sound), the filament slips and the drive gear gets full of PLA dust.

Simply disassemble the cover tube and the nuts, clean them and adjust them as best as you can.

Quick Start Guide

Installation clips
The following 3 clips will guide you through the installation process of your Creatr. 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 Creatr

In this clip, you will be guided through the unpacking of a brand new Creatr. 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 Creatr 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 Creatr 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 Creatr!

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 Creatr. 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.

Filament Guide

ABS
  • Extrude at ~ 225o C.
  • Requires heated bed.
  • Works reasonably well without cooling.
  • Adheres best to polyimide tape.
  • Filament tolerances are usually tighter.
  • Prone to cracking, delamination, and wraping.
  • More flexible.
  • Can be bonded using adhesives or solvents(Acetone or MEK).
  • Fumes are unpleasent in enclosed areas.
  • Oil Based.
PLA
  • Extrude at ~ 180-225o C.
  • Benefits from heated bed.
  • Benefits greatly from cooling while printing.
  • Adheres well to a variety of surfaces.
  • Finer feature detail possible on a well calibrated machine.
  • Prone to curling of corners and overhangs.
  • More brittle.
  • Can be bonded using adhesives.
  • More pleasant smell when extruded.
  • Plant Based.
