Replicator Dual: extruder fix based on Makerbot Rep2 fix by RodLaird Apr 6, 2013


This variant uses the hardware available from the Makerbot store - just tweaks the hinge point to ensure it fits and works under the Replicator dual top mount.

Is that 'Jagged Seams' flag on by default ?

Is that 'Jagged seams' flag on by default ? If so, that's dumb....

There is an optional export flag for STLs that allows for "Jagged seams". Your comment on the resolution transition problem clued me that this may be the issue. Disabling this option cleaned the STL...

I will be trying out the 2.2 MW as soon as I clear my desk queue. As it happens I sold my Replucator dual with the extruder fixes to a mate of my son who is now putting it to good use. I am now enjoying a Rep2X - which of course comes with the "next generation" extruder heads. You will have twigged to this change if you look at my things, as I have produced a set of hinges / handle for the lid. Nice kit. I am hoping the acquisition of Makerbot by Stratsys will bring some of their software patents; some of them have the potential to significantly improve slicing / printing... We shall see ;-)

The source files are there if you want to tweak things further for any reason. The original suggestion of setting the wall thickness to 3 and fill to 10% works well.

UPDATE: There is an additional STL which has been exported from Rhino3D with some different settings which should make it easier to print with the latest version of Makerware. (The previous version works fine with Skeinforge/ReplicatOrg)

This mesh is non manifold. Makerbots latest slicer creates extra plastic. What did you use to export this ?

Interesting. I have reloaded the above STL file in Rhino and it shows no non-manifold edges. Netfabb also shows that the STL has no problems. So I am not sure why you think it non-manifold... In any case as noted in the instructions, the source files are available in Rhino (3DM) and STEP formats. Let me know what software is showing this STL as non-manifold... I am curious. I print using ReplicatOrg generally because of its greated control so would not pick up a makerware problem. cheers R
