PROBLEM: Objects don't stick to the heated build platform
Possible cause
1. Is the bed clean?
2. Is the heated bed on?
3. Is the bed level?
4. Distance from head to bed
ok?
5. Is the print speed of the first
layer low enough?
6. Is the bed flat?
7. Dual extrusion: Do both
extruder-heads have the
same height?
PROBLEM: Bad print quality
Symptom
Changing slicing settings in
Repetier-Host doesn't have
effect.
Circles are not
round/Dimensions differ
Printed parts with sharp corners
have large vibrations/waves
visible.
The part sags after a few layers;
this happens mostly to smaller
parts with thin walled features.
Quality of small parts is really
bad

issues occur with the PEEK middle isolation part. Try to post drill it with a
2mm drill.
Possible solution
For good bed adhesion of the object the bed must be clean from
dirt, dust and grease. A recommended cleanser is blue
spirit/alcohol/thinner.
An alternative way to get good adhesion is to use blue painters tape.
This can be a good idea for small objects. Downside is that it
sometimes sticks too well and takes an enormous effort to get your
part from the build plate after printing. Which could cause damage
to the printer.
Other people have obtained good adhesion by using hairspray on
the heated bed.
The recommended bed temperature for PLA is 55 degC
The distance between nozzle and bed must be the same
everywhere.
Make sure the distance between bed and hot-end tip is close enough
for first layer. Adjust fine-tuning mechanism accordingly.
Try reducing the speed for the first layer, by for instance adjusting
the feedrate override in the Repetier-Host software or on the display
unit.
When the bed is not flat, due to assembly, damage or from the
factory, it is impossible to have the same distance from bed to
nozzle over the whole surface. If this is the case, try to bend the bed
by hand. Make sure you don't introduce forces into the bearing of
the y-axis.
Another possibility for dual-extrusion printers is that the two hot-
ends are not leveled closely enough relative to each other. This can
cause the lower hot-end to adhere to filament deposited by the
other one and push it aside.
Possible solution
Make sure you have selected/activated the correct slicer settings.
SFACT is the slicer of preference. Slic3r is not configured out of the
box.
Check belt tension
Make sure y-axis bearing is fastened enough to the z-axis carrier and
also make sure the 4 bolts are mounted with washers.
Are pulley's set screws fastened?
Make sure all parts are fastened correctly, to ensure optimal stiffness
of the construction and mechanics. When certain bolts are loose the
printer might vibrate more than normal causing bad quality prints.
The temperature of the filament is way too high.
The extrusion is not good enough. Make sure nozzle exit is clean and
also extrusion mechanism is working properly.
Slow down the print speed to give part more time to cool down.
Decrease temperature
Slow down speed.
Print multiple parts in the same print. Use the multiply plugin in
SFACT/Skeinforge.
