Hi I've been using my new HS for a few days now and have done some successful small prints. The printer is really fast btw!! However, I'm having trouble with my first large print (of an architectural floor plan).
In order to stick the first print layer to the heated bed I've been using a very dilute solution of ABS and acetone. The prints stick to the beds beautifully. However my subsequent layers are rising up and creating blobs and granules (see picture). Can anyone suggest how to prevent this? The print is with PLA (Maxx) from my left extruder at 200 micron using the presets that were provided by leapfrog for medium quality.
In addition, there was too much stringing while the print head was moving between two columns. I've noticed this with other smaller prints too. I believe the retraction settings need to be altered. Anyone with suggestions on the exact settings?
Please try and raise the infill percentage and lower the printing speed to 6000 mm/sec, for example. Let us know how it went.
You can also use the nozzle fan to 100%.
I tried both as well as increased the flow rate to 107% There is still a major problem of underextrusion. Please see the pictures of an ongoing dual PLA colour print. Both colours are underextruding.
Thanks for the photos.
If you are using the nozzle fan you should consider raising the PLA melting temp to about 220 C. It may be also that the nozzles are clogged and they need replacement.
I tried 220C. It helped very slightly. The nozzles definitely aren't clogged because when I manually extrude the material using the jog dials it extrudes fine. Could it be a case of the filament feeder somehow not sufficiently feeding enough material. What I've noticed is the maximum amount of underextrusion happens at the start of the print. As the print progresses, the extruder does start increasing the amount of material being extruded. It's almost like the machine is a slow starter!
I seem to have hit a sweet point in temperature for PLA of between 195 and 200. I guess it must depend on the filament used.
Hilary the underextrusion was solved by making the extra restart distance in Simplify3D 0 instead of -0.8. I'm still getting a slight amount of stringing though. I haven't found the correct retraction settings that prevents stringing and doesn't causing underextrusion.
Also I've had to keep by bed heated to 60C in order to prevent the first layer of prints from rising upwards. I'm still not getting a perfect first layer especially with slightly higher speeds (considering the selling point of the machine is higher speeds)
Does anyone have an exact setting for PLA that just works perfectly on Simplify3D?
These setting are a good base line. A neg restart in simplify3d functions as a priming function so more filament would come out. If the value was a positive it would retract more. The most up to date setting are loaded to the knowledge base for the Creatr HS support page.
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
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.
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.
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!
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
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.
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!
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.
