This guide is describing an assembly of a single spool holder. Your package should include 5, simply repeat all the steps again until you finish all spool holders.
⬢Take the black plastic spool holder base and turn it upside down.
⬢Using cloth + detergent or IPA clean all four corners from dust and grease.
⬢Let the surface fully dry and proceed to the next step.
The Buffer plates are protected by a thin protective film on one or both sides, you can remove it now. Be careful during the assembly to avoid scratches.
⬢Now turn the Buffer and place four nuts on the screws. Before you start tightening, please read the following instructions:
⬢DON'T TIGHTEN the screws too firmly. You will deform the plates and the Buffer might not work properly. Make sure the plates are parallel and not bent.
⬢It is enough just to catch the nut (use its entire internal thread).
Use this approach on all parts, which are holding the plates.
⬢Turn the Buffer back, two holes are facing to the right again.
⬢Take three s-buffer-spacer parts and place them on the side with two holes.
⬢Secure each s-buffer-spacer with a M3x40 screw.
⬢Take two s-buffer-hook-uni parts and place them on the other side. This position of hooks is compatible both with MK3S and MK2.5S, but you can rearrange it.
⬢Take the last s-buffer-spacer and place it to the corner.
⬢Secure each printer part with a M3x40 screw.
⬢Use six M3n nuts from the other side and tighten the screws. Keep in mind the proper tightening. Avoid deforming the plates!
⬢Now turn the Buffer and place four nuts on the screws. Before you start tightening, please read the following instructions:
⬢DON'T TIGHTEN the screws too firmly. You will deform the plates and the Buffer might not work properly. Make sure the plates are parallel and not bent.
⬢It is enough just to catch the nut (use its entire internal thread).
Use this approach on all parts, which are holding the plates.
⬢Take the 150mm PTFE tubes and slide them in to the smaller of the two printed parts. Make sure the PTFE tube sticks out on the other side (inside the Buffer) just 2-3 mm, not more.
⬢Secure the PTFE tubes using five M3x12 screws. You can tighten them slightly above the surface.
CHECK EACH PTFE TUBE with a piece of filament to ensure it can move smoothly inside the tube. If not, release the screw a bit.
⬢Did you assemble all five spool holders and the Buffer?
⬢Do they look like those in the photo? Note that the hooks on the buffer will differ depending on your version.
There are 5 screws (M3x12) remaining, keep them for connecting the printer tubes to the buffer, later while reading the Handbook.
⬢Let's continue with in the next chapter.
