7.4. Z Axis Rods and Leadscrews
The Z axis leadscrews and smooth rods on your F306 are lubricated at the factory with a long-life lithium-based
grease. This lubricant should provide thousands of hours of trouble-free use. The rods
should not be lubricated
with any other lubricants! Doing so may void your warranty.
Recommended service interval: once per year, or every 2,000 hours of run time
7.5. Print Head
Regular Maintenance
Remove Plastic Debris
After every print, clear leftover plastic from the print head so it will not collide with it when it homes. Stubborn
plastic can be more easily removed by heating the print head to ~200
o
C and removing the now-soft plastic.
The preferred method is to take a folded-over paper towel and use a pinching motion on the nozzle while sliding
your hand away from the nozzle.
Cleaning beyond this is more a matter of cosmetics than functionality.
Recommended service interval: after every print
Check Heat Break Tightness
Periodically it’s a good idea to make sure the heat break section is firmly threaded into the heat sink. It’s also a
good idea to check this if you move, adjust, or otherwise touch the print head for other maintenance or service.
Figure 44: Print Head Assembly
The hot section of the print head (right piece in the above image) consists of the aluminum heater block, a brass
nozzle, and a stainless steel heat break. The top of the heat break threads into the heat sink portion of the print
head (left piece).
Do not disassemble the hot section of the print head: it has been carefully assembled at the
factory to prevent leaks.
The threads of the heat break are coated in a thermal transfer paste to aid in heat transfer from the stainless to
the aluminum. If you disassemble the print head, take care not to wipe off this thermal paste.
