Description
Here we continue the development of the 3D Printer Distributive Enterprise. We discusses how to implement automatic bed leveling.
Roadmap for 3D printer is here - http://opensourceecology.org/wiki/Roadmap#3D_Printer_Roadmap

I,
don't
know
if
you
might
have
seen
torbjörn
of
the
roadmap
on
the
3d
printer,
but
also
the
scalability
or
modularity
would
mean
that
we
can
put
all
kinds
of
heads
onto
that.
So
just
for
your
reference,
the
road
map
page
on
the
wiki,
if
you
go
to
the
3d
printer
roadmap
under
the
full
modularity
and
product
ecology
achieved
part,
there's
a
notion
of
all
the
different
kinds
of
heads
that
we
can
put
on
it
up
to
things
like
laser
heads
or
paste
extruders
for
ceramics
things
like
that.
A
We're
going
to
build
that
at
factory
farm
myself
and
alec
we're
going
to
report
the
learnings
take
pictures
take
documentation
record
what
we
can
as
far
as
how
suitable
that
is
that
current
Prusa
i3
from
Folger
Tech
is
for
the
for
the
workshop,
because
some
of
the
critical
parts
will
be
how
good
are
the?
How
good
is
the
part
source
ability
is
the
thing
actually
working?
Are
all
the
parts
reliably
produced
so
so
really
working
out
the
details
of?
B
C
B
To
have
it,
linear
that
the
tool
head
and
not
in
the
bed,
because
if
you
have
it
in
the
bed,
then
you
lose
scalability,
because
you
need
to
have
the
water
going
into
the
bed
and
if
the
bad
moves,
then
you
need
a
very
long
wire
and
you're
limited
like
they
have
the
sensor
in
the
print
n
than
you.
You
can
scale
up.

Maybe
the
way
to
refactor
the
this
applies
to
d3d
right.
This
is
a
whatever
we
decide
here
will
probably
be
transferable
or
we
consider
d3d
in
that
process.
So
maybe
the
next
step
on
that
would
be
to
assess
so
take
all
the
choices
so
far,
maybe
do
a
matrix.
Okay,
here's
the
advantages,
advantages,
disadvantages,
cost
and
effort
estimations
for
each
something
like
that
for.
B
C
B
A
B
A
We
can
talk
about
options.
What,
as
far
as
the
base
kit
like
for
the
workshop,
includes
that
it
doesn't
include
it
whatever
it
includes,
we
can
make
those
decisions
based
on
costs
and
performance
of
those
things.
Okay,
so
I
scanning
through
that
article,
it
doesn't
say
much
about
well
I
mean
the
practice
I
kind
of
looking
at
it,
I'm,
not
getting
a
good
feeling
for
the
amount
of
cost
time
or
ease
for
each
option
kind
of
saying,
hey:
these
are
the
options.

A

A

Yeah
so
I
would
say
reliability
is
this.
Would
this
be
good
like,
for
example,
one
fifth
of
layer
thickness,
plus
minus
fifty
percent
of
that
layer
thickness?
Is
that
do
they
have
figures
of
Merit
that
anyone
uses,
or,
I
would
say,
150
layer
that
would
be
kind
of
like
what
you
definitely
would
need?
Maybe
it's
even
one-tenth
the
layer
thickness?
A
A
C
A
Something
words:
it
would
actually
require
modification
of
the
nozzle
head,
but
it's
not
the
nozzle
but
something
equivalent
to
the
nozzle
hitting
the
like
a
little
little,
a
probe.
That's
just
attached
to
the
head
there
or
it's
such
that
when
you
touch
down
because
the
plastic
is
molten,
it
should
not
interfere
with
the
conduct.
The
making
of
the
contact
and.
F
B
F

A
A
E
C

F

F

So
as
a
requirement,
or
is
this
automatically
taken
care
of
that
you
don't
need
to
reprogram
the
I'm
not
familiar
with
the
tool
chains?
Enough,
I
mean
there's
the
program,
that's
on
the
the
firmware
on
the
printer
itself.
That's
what
you
need
to
change,
but
you
don't
also
things
like
configuration
files
is
that
is
that
year,
you're,
considering
that
as
part
of
the
firmware.
A
A
I
think
I
need
to
get
going
like
2pm
here,
so
maybe
we
could
start
wrapping
up,
but
but
so
we've
got
the
specific
the
requirements
for
bed
leveling.
Maybe
we
can
finish
off
on
that,
and
the
next
step
would
be
to
look
at
evaluating
the
implementation
of
that,
especially
after
we
see
the
build
itself,
I
mean
it
might
turn
out
that
we're
struggling
too
much
with
the
kit
itself
and
we
won't
have
enough
time
to
implement
the
bed.
Leveling
I
mean
that's
a
hope.

Good
to
know
so
I
won't.
I
won't
get
troubled
by
that
when
I
get
to
that.
I
didn't
know
that
okay,
okay,
so
we're
gonna
have
to
pretty
much
before
the
bill
that
we
want
to
think
about
how
we
manage
the
well.
We
should
probably
build
just
build
it
and
go
through
that
unless
we
refuse
to.
Let's
see,
is
it
worth
while
to
go
through
that?
If
we
know
we're
not
going
to
use
that
I
mean
we
just
yes.
B
A
C
C
A
A
We
can
keep
refining
the
requirements
as
we
get
better
at
the
technique,
because
actually
requirements
are
kind
of
iterative,
as
you
find
something
you
find
out.
Wow
I
actually
need
this
too,
but
I
think
that's
a
decent
start
saying.
Basically
we
require
no
movement,
no
extra
movement
and
no
physical
modification
outside
of
adding
a
sensor
of.
F
A
Like,
for
example,
lilz,
but
we
can,
we
can
borrow
that
man
I
mean
they've
got
the
whole
system
worked
out.
If
we
want
to
simply
say
okay,
we'll
do
that,
because
it's
absolutely
proven
and
it
absolutely
works.
That's
one
we're
apt
to
go,
or
we
can
say
we
will
experiment
looking
more,
but
we
know
there's
a
one,
there's
a
solution
right
there.
That
does
work
and
it
might
be
worth
considering
you.
