See my post here for my settings and a video. http://umforum.ultimaker.com/index.php?/topic/8506-anyone-got-any-tips-for-printing-when-the-first-layer-has-lots-of-tiny-part/?p=86450

I just found raft to be very usefull for a good first layer every time and even with a lot of small details in the first layer.
My raft settings peel of really easy for my PLA. Maybe not with other brands.
I use raft every time now. Okay i waste some pla on the raft, but all my prints works on the first layer.
My settings is like this.
Extra margin = 5.0
Line spacing = 2.0
Base thickness = 0.35
Base line width = 1.0
Interface thickness = 0.25
Interface line width = 0.4
Airgap = 0.215
First layer airgap = 0.0 (why both airgap and firstlayer airgap?)
Surface layers = 2
Surface layer thickness = 0.25
Surface layer line width = 0.7
My temp is 180 degree for raft and first layer and then use the plugin change at z to set temp to 200 at layer 1 so layer 0 is 180.
Then in advanced settings i set first layer to 0.25 heigth en 0.5 width.
In my start gcode in set fan on 100% for the raft
And fan settings to be on 100% from layer 0.
A small video to show it all https://fbcdn-video-b-a.akamaihd.net/hvideo-ak-xpf1/v/t43.1792-2/10810908_10152821049117954_317418998_n.mp4?rl=1500&vabr=960&oh=8fe024d0d7dcb9cb1ca2a10510cb999c&oe=54ABDAF3&__gda__=1420548519_f0867c389e4d5d96eb586d6de4560f08
And another video of a larger object.

ps. this both works on heated glas and on kold bed with blue tape.

You can oneclick install it here http://software.opensuse.org/package/Cura
It's the one under the repo "home:Kenzu:3d-print"
Hope you enjoy it.

I think you need to compile it your self.
Look here for instructions
https://github.com/daid/Cura#debian-and-ubuntu-linux
One problem I see is that it's for i386 or amd64, a raspberry pi is ARMv6, so I think you need to edit package.sh and add ARMv6 support.
I the top add this to the list of build targets
#BUILD_TARGET=debian_armv6And then after this add a new build target
#############################
# Debian 64bit .deb
#############################
if [ "$BUILD_TARGET" = "debian_amd64" ]; then
export CXX="g++ -m64"
A LOT CODE REMOVED HERE FOR BETTER VIEW
#############################
# Rest
#############################Add the new build target before ^^^ #REST
with this code:
#############################
# Debian armv6 .deb
#############################
if [ "$BUILD_TARGET" = "debian_armv6" ]; then
export CXX="g++ -march=armv6 -mfpu=vfp -mfloat-abi=hard"
if [ ! -d "Power" ]; then
git clone https://github.com/GreatFruitOmsk/Power
else
cd Power
git pull
cd ..
fi
rm -rf CuraEngine
git clone ${CURA_ENGINE_REPO}
if [ $? != 0 ]; then echo "Failed to clone CuraEngine"; exit 1; fi
make -C CuraEngine
if [ $? != 0 ]; then echo "Failed to build CuraEngine"; exit 1; fi
rm -rf scripts/linux/${BUILD_TARGET}/usr/share/cura
mkdir -p scripts/linux/${BUILD_TARGET}/usr/share/cura
cp -a Cura scripts/linux/${BUILD_TARGET}/usr/share/cura/
cp -a resources scripts/linux/${BUILD_TARGET}/usr/share/cura/
cp -a plugins scripts/linux/${BUILD_TARGET}/usr/share/cura/
cp -a CuraEngine/CuraEngine scripts/linux/${BUILD_TARGET}/usr/share/cura/
cp scripts/linux/cura.py scripts/linux/${BUILD_TARGET}/usr/share/cura/
cp -a Power/power scripts/linux/${BUILD_TARGET}/usr/share/cura/
echo $BUILD_NAME > scripts/linux/${BUILD_TARGET}/usr/share/cura/Cura/version
sudo chown root:root scripts/linux/${BUILD_TARGET} -R
sudo chmod 755 scripts/linux/${BUILD_TARGET}/usr -R
sudo chmod 755 scripts/linux/${BUILD_TARGET}/DEBIAN -R
cd scripts/linux
dpkg-deb --build ${BUILD_TARGET} $(dirname ${TARGET_DIR})/cura_${BUILD_NAME}-${BUILD_TARGET}.deb
sudo chown `id -un`:`id -gn` ${BUILD_TARGET} -R
exit
fiNow build the package and hope for the best with
sudo ./package.sh debian_armv6
sudo dpkg -i ./scripts/linux/cura*.debJesper

okay, this i kind of bad :-( Hope Daid will respond to this. But nice catch.
-
Nice, but could you please enable builds for 12.04 precise to?
-
Actually that creates little vertical spikes. "non-printing" is harder than one would think.
I works fine i KISSlicer for me. I only use 0.075mm z-lift. And for me a small spike is better than a long drag-line.
-
If just cura did a small z-lift on non-printing moves. Like 0.1-0.2mm then it would make a nice finish.
Anyone got any tips for printing when the first layer has lots of tiny part?

Okay jeg made a new link. Hope it works.
