circular size inner diameter

Hi, Im trying to get a reasonably accurate diameter on some of my cylindrical parts, but I can't seem to get within range so to speak.


I'm fully aware that 3d printers are no exact toy, but from my experience with previous printers I've been able to get within +/- 0,3 mm in range. 


In this case it seems and this only concerns part that have a inner diameter/circle, the prints are of by circa 1,5 mm. 


The parts concerned is suppose to be 80 mm outer, 71,3 inner. But they turn out to be 78,7 mm outer and 69,8 mm inner. 


I believe this is a bit to much of. 


Oddly enough, If I do a test print with exactly the same settings on a 25 mm cylinder, it comes out close to perfect, 25 mm spot on.  


It seems that as soon as the part have a inner diameter, then something happens either in the g-code or if it is the printer it self? 


I'm using simplify 3d, but will run a test via Cura as well, but if anyone here has experienced similar problems, then it would be most helpful getting a fix on this.  


Yes, this happens to me as well. I believe that the software offsets the extrusion so as to prioritize the outer dimensions first. 


You can try using a smaller extrusion width, slowing the extrusion on the outer perimeters. 


Other than that you can adjust the extrusion multipliers for that particular filament as well. 


Just my guess, let me know how it goes. 

Kisslicer (and now S3D, but haven't tried it) has an option called "inset".
This essentially shrinks wall thickness.
So between the inset option and global scaling you can get close. Of course they interact with each other a little so it will take some tweaking to get there. I've been able to get parts that fit together (mating a 3D printed part to a non-3d printed part) to work using that method.

 

Ok, Thanks for the tip, shall look into them, 



Tried using Cura as slicer, but did little to help. 


I have the speed set to 2000 mm/min already, problem with my drivers as it seems, new ones are on the way from lpfrg, will see if this changes things, all  though I'm doubtful. 


Perhaps try Kisslicer then.  


Do you use simplify 3d as host, or have you found better ones for this?  

I actually just use Repetier for the host. S3D would probably be fine as a host also.
Inset was the main reason I kept using Kiss. The other reason is it seems to handle thin walls better.
I know S3D has made improvements but Kiss works so just I keep using it. I do use the latest Kiss beta versions. The latest is available from their forum, may not be on the main web site.

 

One thing I just remembered. The preview of Kiss gcode in S3D may look odd. If I remember they use different commands for rapids, so it may look very stringy :-0

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.

  • 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.
