Tuning the Makerbot

[Yepher]

My journey into 3D printing is progressing. I definitely have a lot to
learn here.

I have been printing raftless on my TOM w/ ABP. I have gone through
some of the Skeinforge settings and for the most part the printed
"things" are looking good to me. This tool got me a long way to make
good looking things (http://makerblock.com/profilemaker/).

Unfortunately, the first layer and the last layer does not seem to get
filled in all the in. So I have gaps on the two outer surfaces. All
the rest of the part look good to me.

Anyone have any hints about what I should tweak to get a better first
and last layer? There are so many setting in Skienforge it is a bit
overwhelming...

Thank you,

Yepher,

I'm not sure if I was inspired by your success or it was just a coincidence that I got some free time, but I got my ToM working over the weekend. I also did a calibration cube and the 3D knot that comes with ReplicatorG. Looks pretty good so far, but I think I am doing something wrong because it is rather slow. But the quality is quite nice.

As far as raftless, I haven't tried yet, but I see the motivation, between the difficultly of removing the raft and the amount of time it takes to print the raft.

You probably found this page on the Makerbot site, but in case you missed it, there are some key points here:
http://wiki.makerbot.com/thingomatic-doc:raftless

BTW I hope the other folks don't mind we discuss our ToM builds on the RepRap group - but I think at this point it is general 3D printing questions rather than ToM-specific stuff. Let us know if there is an issue. Even though this is working I might stop by PS1 for the build out in a couple weeks. Would folks mind if I brought my ToM?

Thank you,

Im pretty sure no one will mind much, but space  and time will be limited with 20 rep raps getting built at once.

Why did you want to bring it? If you're showing it off, you'd be better off bringing it to a tuesday night open house. That's a more apropriate venue...

Sasha,

 

Sure, whatever you think. I was thinking of bringing it more to be inspiring. I know that hearing Yepher’s success helped me. If bringing it on a Tuesday is better then that’s what I’ll do.

[Sacha De'Angeli]

heck bring it, we may need to print spare parts in case something breaks!

Doug,

That is great to hear that you got your ToM working. I have not tried
the 3D knot yet. Did you use support material for that?

I went through the page you suggested for tuning Skeinforge to do raft-
less printing. That did help me with the base layer. I had just
unchecked the "Raftless" check box. Setting the raft and interface
layer thickness to zero seems much better.

Let me know if you are going to the PS:One RepRap build. I would like
to see your TOM. I am still trying to clear out that evening so I can
come and build a RepRap (and if there are still opening). I want to
get another 3D printer to see other technique in building these
things. I sponsored this KickStart project:
http://www.kickstarter.com/projects/93832939/makerslide-open-source-linear-bearing-system
My plan to to build a printer using aluminum extrusions for the frame
and the axis. I will use this linear bearing for the Z and X axis. The
end of mid July I should be getting a lot of bearings and rails and
other parts. The nice thing about that project is that kickstarter
lives in the Chicago suburbs.

Anyway I look forward to any other insights you may have on how to
make the best prints possible.
