mircea_popescu: whoa check
that out, apparently you can say intelligent
things in spanish!
☟︎ moiety: mircea_popescu:
thats something we have in abundance!
take *that* london!
mircea_popescu: CheckDavid women under 30 spending
their life in
the buff.
moiety: there's more people in london
than
the whole of scotland
CheckDavid: mircea_popescu: which
trend? Posting pics.
Taking
them? Or just hanging around naked on
the street?
mircea_popescu: i always
thought it's quaintly corrupt and
thus quite comfortable.
Mats_cd03: or at least send
their children
to western schools
Mats_cd03: yeah, even if youre rich,
the weathy and smart chinese
try
to leave
Mats_cd03: and
the nouveau rich are numerous enough
to leave
the country
moiety: CheckDavid:
they generally look quite happy
Mats_cd03: i anticipate a
tripling of chinese expats in
the next
ten years
mircea_popescu: CheckDavid actually
that's
the ukraine, and i'm
trying
to get a
trend going.
mircea_popescu: weren't
these fuckwits all over everyone's case all
through
the 90s about how
they're supposed
to deflate ? argentina, brazil, asia,
the works ?
mircea_popescu: the imf is now "warning of low inflation". for
the love of all
the gods,
this is like living in a dali painting.
mircea_popescu: kickback culture is about as ingrained as kleenexing in
the us, i just can't imagine any context in which it'd have been omitted.
cedivad: yes, it is, and
thank you (again) :)
mircea_popescu: we're
talking cyprus here, which is worse
than greece, which is about 50x as bad as chicago in 1890.
mircea_popescu: i can't for
the life of me imagine
those firms didn't
throw him kickbacks under
the
table
mircea_popescu: nubbins`:what if i
told you...
that your investment went straight into
the pockets of cypriot marketing firms? <<
that's only part of it. even should
the guy have been fucktarded enough
to pay ratecard, which is not entirely impossible, given how well his brain worked otherwise,
assbot: Last
trade for S.MPOE on MPEX was at 0.00094649 BTC [+]
cads: and yes, pnc connectors (an amazing
technology, really!) are definitely one of
those
things
to have on hand
cads: so whatevs, we have what appears
to be
the reason for incidents
cads: and didn't pop out due
to a jam
cads: I don't know what caused
the initial explosion but we
thought we fixed it and it popped out again
cads: diametric: we
talked
to john about
the push
to connect - apparently
the first batch was cheap chinese stuff
diametric: Now I have spare PTC fittings,
though I haven't had any jam issues.
diametric: I saw
that, did you make sure
the PTC
teeth didn't break? Every
time I've had
that happen, PTC
teeth broke and
the whole fitting was weaker as a result.
cads: right,
that's happened
to us but it was under our supervision at
the
time
diametric: But it won't cover all jams (such as popping
the bowden
tube and filament just freely spooling in
the air)
cads: I would hope
they do
cads: maybe
they implement jam detection
diametric: and detect when it stops extruding due
to a jam.
diametric: Yeah
that is lame. You can do a really simple encoder on
the idler bearing of
the extruder
cads: but
the features
that gives seem
to be lame duck - it can cancel
the print if you run out of filament, and
that's it
diametric: Are
they doing it for calibration or for safety during a jam?
cads: diametric: a company is launching a printer
that has a feed sensor
that detects
that filalement is coming out of
the extruder drive and
travelling into
the bowden
tube
diametric: I was next
to him at Makerfaire NYC, its a crazy machine but like $10K USD in cost for a very marginal improvement over a similar $2K machine.
cads: I was
thinking feedback loops with sensors reading
the filament
travel, extrusion rate, or extruder pressure
diametric: Theres a crazy guy, I
think his name is Jetguy on various forums, built such a machine
though.
diametric: cads:
the servo motors
that have
the
torque required as much more expensive
cads: the math/control/coding is not
too hard
diametric: for feedback, is
the primary reason.
cads: punkman: problably
the entry cost for
the design work required for
the sensors is what's
the main issue
punkman: cads, I wonder why
there aren't more people working on adding servo/feedback loops on an extruder
cads: (and
to a less extent, variable material properties)
cads: (the reason
to go
to all
this
trouble is, of course, variable color)
cads: even if your extruder has a motor on board for
the mixing
kakobrekla: well you can send as many as you want,
those are free.
ozbot: X-BT -
The new marketplace for
trading Bitcoin with Litecoin, Namecoin and Altcoin
kakobrekla: meaning you need some vol
to average out, is all im saying.
kakobrekla: yes Apocalyptic but
the signal must not be fucked or else its useless
Apocalyptic: would be nice
to have
the charts like other coins do
cads: already I feel like
there's
too much sway in
the arm and in
the printer columns
cads: I'd definitely feel iffy about putting an extruder motor directly on
the end of
the delta effector arm
cads: and some practical ones - like
the bowden
tube
twice popped out of its push-n-lock connector
cads: I don't know anything other
than bowden
punkman: I've been
told bowden is a headache, but I wouldn't know
cads: diametric: how are you
those working for you?
diametric: I'm even using
the magnetic ball joints
cads: we can put
the extruder out of
the space I
think
diametric: Theres a few
that aren't, but most of
them are since its a lot of weight
to move around
kakobrekla: dunno, spit out
the numbers, daily, weekly, monthly
punkman: cads,
there's still
the extruder's stepper, unless you go bowden cable
cads: I estimate $200-$300
to have
the stuff made
cads: I'm
thinking of lasering an acrylic envelope for
the whole printer
Apocalyptic: kakobrekla, wanted
to contact
them regarding
the lack of market listing for ATC
cads: to wit,
they already do
cads: the steppers can easily live outside of
the volume in
the romax design, luckily
punkman: if you build an enclosure,
the heated platform and extruder can probably heat up
the whole
thing. You just want
to avoid overheating
the steppers after
that.
diametric: You could
try keeping
the part warm with IR heat lamps pointed at
the build area
cads: also
the outer envelope of
the machine _needs_
to be completely inert and safe
cads: we don't want
to build our next printer but we will, if we can't find a well engineered delta printer with heated build volume

cads: hey have you given any
thought
to
the
thermal engineering
that'd go into a heated build volume for a delta beast?
diametric: I've been
to SeeMeCNC's machine shop, John's a friend of mine
cads: get it
tuned up and you have a formidable machine
cads: yep, it's given us
the deepest of headaches and
the purest of joys :P
[KS]: if you have enough experience, you can even evaluate
the "avg lifetime worth" of a customer,
that helps price your service as well.
[KS]: cads: my 0.02c - customers bring customers. start with
the cheapskates and guess what your future customers will be ... it's very important you chose your "inital" group of customers carefully and
that you don't hesistate
to fire
the ones you don't want. return customers are more valuable
than one-offs.
benkay: over deliver on quality,
though. not features or
time spent on
the
thing.
punkman: cads, cool stuff, haven't had a chance
to play with a delta bot. I've built a couple Prusas myself, calibration was kinda impossible
though and I had better
things
to do, so I just got rid of
them.
cads: it is a delta gantry printer with a cylindrical build volume approximately 200mm in diameter and 300mm
tall - a Rostock Max, manufactured by
the awesome See-Me-CNC
cads: lol, even if I produce failure after failure
there are still gonna be
the moments where everyone is brilliant!
ThickAsThieves: at least you dont need
to spend 20 years being miserable
