Support material as elevated raft

Postby firesped » Sun Mar 12, 2017 5:28 pm

I've been printing out some star trek ships. since I need higher quality on both sides of the saucer section of the ship. I have slip it into 2 parts. But I have made a slight keyed peg in them so they line up.

I increased my dense support to 85% infill to match the raft settings and I have gotten good results with the inside hole part.

The issue I seem to be having is with the parts with the peg that has the edge on the outside. I am trying to figure out how to get the support material to print beyond the outer edge of the model so that it functions more like a raft.

I can see 2 ways it can be done right now.
option A) get raise3d to add this into ideamaker.
option B) use the dual extruder to print out a non existence part at the edge to try and get the support material to behave how I want it.
I make a part that fits exact around the part I do want.
set that part to right extruder
do not load filament into right extruder
support material will be designed to support the larger edge size to give the effect I desire
(if this works)

using option B the slicer seems to do what I want it to do, now to print it out and see if it works.

first time I have tried dual extrusion on this firmware and that is one funky bug. the Y was offset and then the X was offset when it went back to print that.

Have you tried manually placing supports? If you make them large, say 7 or 8 mm, you can position each one halfway under the edge you are supporting.

I have just started to do some dual extruder printing as well. I noticed that when I bring the STL files into ideamaker, they are not aligned as they are in my CAD model. There is an align button, see this topic... http://forum.raise3d.com/viewtopic.php?f=3&t=673&p=6319&hilit=dual+extruder#p6319

I ended up generating the file for dual extrution then converting it back to single by manually stripping out the g-code for the second extruder. I need to re-setup my printer for printng.

I'm running a custom firmware based on the marlin RC. I had not played with dual extrution so I am going to have to figure out what is going on and figure out why the printer is getting lost on tool change.

Is this option the same as your option A?
