Improvements on the Creatr ?

 Improvements


Hi Leapfrog.


I bought a Creatr a few month back. My impression of the Creatr is that the design is the best on the market, It is more or less designed exactly as I would had don my self..... except for a few things that I'd like to share.

1. Z-homing sensor is extremely accurate and precise. The sensor has the same precision as the micro-stepps in the stepper motor. but the sensor measuring the position of the most flexible part of the hole machine, making it impossible to calibrate the bed hight and not loosing your temper.
I moved the sensor to "the best position" , right-front corner. Now there is no problem adjusting the whole surface +- 0.02mm in a few seconds.. well. not that few maybe ;-)

2. The bed heater works really god on this machine if it is attached properly. in my machine the heater was glued very nicely along the edges an a large "blob" of glue around the temp-sensor, plus a few dots of glue here and there . It took app. one hour to heat it to 90 deg. and then it was only hot a bow the "blob" (less then 50 deg in some areas ).
I cut the heater of the glass and glued the whole surface. now 20 deg to 100 deg takes less then 20 min, and the whole printing area is within +-5 deg.

3: The cable to the X-stepper have ruined one print for me, and gets jammed when X homes before Y. from large Y position. I put a clip on the Y gejder
for the cable and led it straight down to the "electronic box" instead of going back to the right Y-stepper and then down. Works fine and locks better.

4. I changed the firmware to prevent the extruder stepper hitting the left Y-stepper (especially when the cable-chain goes in between).


Other stuff I changed or will change or would appreciate on the machine.

5. Why not use the whole printing area 270 X 350 mm? Works fine on my machine, however there is no margins to do this. It looks like it was meant to be this large in the design but reduced some were along the way?

6. Put the cable-chain along the x_axis only and then from X-motor straight down to electronics.

7. Take away the part of the alumina in front of the fans ( stopping the annoying whining sound).

8. If I needed a cooling fan to cool the print object it would be nice to have the cables there from the beginning. it is rely tough to put in the cables in the cable-chain afterwords. The electronics has the output for the fan and its easy to fit a fan for cooling, pretty annoying to have a loose cable for it.

9. Optional door and cover, + sound absorbers. I would pay 150-250€ extra for this especially if it includes a temp sensor in the top of the machine and a controlled vent fan .

10. The momentum of the motors is not uniform , the micro steps generating vibrations. (noise and patterns in the print).

11. Bed hight adjusting screws quit tough to work with as it is. I used some "wing nuts" for locking and adjusting the bed without tools. And the locking nut has to be on top of the Al frame ( hight of bed not affected3305 when locked).


/Anders

At the bottom of motion_control.cpp there some thing like:  if ( new_X >max_x) new_X =max_x;
Its easy to fix if you know exactly how it works, One typo and you brake the machine = "don't try this at home"
limitations is hopefully implemented in newer FW. ( my changes only works in my machine = no copy and paste)
Sorry I cant help you /Anders

 

No worries. Thanks.

HI, 


How did you go about changing the firmware ?

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.

  • 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.
