I only use dual extrusion with the 2X. I use HIPS for support and raft though, and not two colors. On those prints, I used the left extruder to print a raft since the object peels off easily without leaving a mark. My only complain about dual extrusion with S3D is that the prints come out with with ...

If you already are using Simplify3D, there is no need to bother with Makerbot Desktop since the quality of the print will be reduced substantially. These are prints from the same STL file for quality comparison. As you can see, Makerbot desktop looks like 3D printed by a shaky hand, S3D gets better ...

So, I'm not the only one having these issues. I have experienced the same problems with the Makerbot Replicator 2X and Simplify3D 3.0.2. I essentially gave up on the Prime Pillar and the Ooze shield when printing with S3D. At the moment, I only use S3D only when I want to define my own support. Othe...

Update: I narrowed the bubbles problem to when printing both objects using the left extruder for the raft and the right extruder for the object. If I print each object individually, the print comes out perfect. I'm using the default profile for Rep 2X Both Extruders. Also, notice how the MB Desktop ...

+1 This happens only when using both extruders.

DarthRevan, Thanks for posting. Have you tried a dual print with S3D? I typically use HIPS and ABS for all my prints. It seems that selecting the "right extruder" profile is fine, but printing with the "both extruders" profiles always gives the bubbles on the surface. I looked into the default profi...

Thank you all for all the help. I printed the cylinders from a factory file sent to me by S3D. As you see, the print came out perfect! I have to say this is the best surface quality that has come out from the Rep 2X. There is still the issue that I have not been able to print a highly tessellated mo...

I would like to add a few my details about my setup. The 2X has upgraded extruders and filament spool support. I'm also using Builtak instead of kapton tape. I clean and level the build plate before each print. With this setup and workflow, the Rep 2X doesn't have any issues printing for 9 or more h...

The material used is ABS. I work in an environment that has had 3D printers for over 20 years. I personally acquired the a Rep 2 and Rep 2X to develop prototypes of my designs and inventions. I have not seen this kind of printing issues with my workplace printers (mostly uPrint models, but some othe...

These are the gcode (MB) and factory (S3D) files from the calibration model. I did not see an option to export a gcode file from S3D. The Rep 2X simply cannot print a perfect circle from day one. I was attributing this to the hardware, but after I printed the calibration cylinders with S3D, which pr...
