Extruder filament drive doesn't turn

Extruder filament drive doesn't turn.  Using Simplfy3d and while manual moves function, manual extrusion does not.  Can push filament through heated extruder fine but the drive wheel doesn't feed filament.  Same for both extruders,  Have had the printer for a long time without ever being able to print !@!!


Did you try to tighten the drive gear in the extruder?

Yes, It was tight.

You many need to readjust the drive gear so that it is tighter so it will grip the filament. Does the drive gear/motor turn when you try and extrude? If it is not turning then check the connector on the back of the stepper motor to make sure it is pushed in all the way. If the stepper is not moving and the connector is plugged in correctly then you will need to contact support. You may need a new stepper motor.

It is tight.  Even without filament it will not turn on command to extrude or retract.  The drive gear motor shaft does not turn on command to extrude or retract.  THe connector appears to be in tight.  I have contacted support; they are working on the ticket.  I doubt that it is a stepper motor problem as both of them are experiencing the same problem; it is highly unlikely that both steppers are shot out of the box.  It is more likely a controller issue, but we'll see what tech support has to say.

Thanks for your input.

Hi Stephen - were you able to get an answer from tech support for this issue? I believe I am having the exact same problem that you had encountered.


- Extrude/retract functionality is not working in Simplify3D

- The drive gear Motor shaft doesn't turn on command

- The COM connector is tight; all other functions that are delivered from the Software to the printer controller through the COM connector DO function

- I also doubt that this is a stepper Motor Problem and my drive gear is also tight


Is this a controller issues? Or possibly a  problem with the Motor overheating? I have tried disconnecting and re-connecting all of the printer COM functions. Really hoping I can avoid taking apart the stepper Motors :)


Thanks for the help!


Nvm - we discovered the issue; apparently somewhere in the software coding there are commands that disable the extrude/retract functionality below some given temperature. We think that this min. extruder temperature variable, that this command is based on, is set in the range of 180 - 190 deg C. When we set the Extruder temperature above 190 deg C the extrude/retract functionality comes back.


If anyone encounters this problem, make sure to check this first. I am not sure where in the motor control code that this command exists; it would be useful to know as there are some low-temperature Filament applications that are already out on the market/in development; so it would be great to know how to change this min. Extruder temp variable.


Cheers,

My Leapfrog Dual firmware has:


#define EXTRUDE_MINTEMP 150


Have never played with the setting.

the #define EXTRUDE_MINTEMP 150 command  is used in order to prevent any potential damage to the hot ends. Basically to prevent cold extrusion.


Tot that end the drive units will not be enabled until that min temperature is reached.

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.
