version ins3DMinipronsole.txt - May 23, 2019 version The Mini is for
printing with rubbery filament. This is the full detailed instructions
for using the Mini with pronsole (the old way). Many of the steps (i.e.,
M.1-M.4) can usually be skipped; see ins3DMinipronsolequick.txt for
minimal instructions. M.1 Make sure long power strip above microwave
oven is on (orange light on in switch at right end) M.2 Make sure Mini
is plugged in to long power strip M.3 Make sure 3D printer computer
(Dell computer left of Rostock) is plugged in to horizontal power strip
just to left of Taz M.4 Make sure the 3D printer computer monitor (above
& to left of Taz) is plugged into power strip left of Taz M.5 If the
power strip left of Taz is off (no orange light) turn it on ((switch at
wall end; orange light in switch should come on) M.6 If the 3D printer
computer is off (no green light in power button in center of front above
silver Dell logo) press the power button (light should come on) M.7
Check that there is sufficient correct (rubbery) filament on the reel
M.8 If the filament diameter is not written on the reel measure the
diameter (calipers are in the Measurement bin) in several places and
write the average diameter on the reel M.9 At the tabletop computer in
MATE Terminal: cura (program to convert surface representation(.stl) to
3D printer instructions(.gcode)) M.10 If Basic appears at the top left

2, 2020 Disassembling & unclogging the printhead - Note: All bolts are
hex bolts unless otherwise stated\*\*\*Incomplete preliminary
version\*\*\* U.1 Unplug the Mini U.2 Discnnect the USB cable U.3 Lift
the Mini down onto a table U.4 Remove the 2 bolts from the top of the
printhead mount (above horizontal rod) U.5 Remove the cover U.6
Disconnect the newly exposed connector U.7 While holding the printhead,
remove the 3 big bolts & washers from the back of the mount (printhead
will come off) U.8 Remove 2 or 3 bolts holding motor (motor will come
off) U.9 Remove big nut holding big black gear U.10 Remove washer U.11
Remove bearing U.12 Remove gear (with washers, bearing, & black washer
on it) if possible U.13 Remove bolt holding tiny fan (fan will come off)
U.14 Remove 2 bolts at bottom holding fan together (fan will come off)
U.15 Remove 2 bolts holding base of fan (base will come off) U.16 Remove
2 bolts with washers that hold printhead together (printhead & nuts will
come apart) U.17 Remove any stuck filament from the gear area by pulling
on the filament & turning the gear (if stuck in place) back & forth
Temporary - reverse steps to reassemble; the fan end of the bottom part
goes to the right, the gap in the metal piece goes in the back, the
wires to the hot end go in back to the right, & the "tail" (motor
holder) on the top piece goes to the right
