did you hear that oh yes come this way come this way
this is what happens when this machine runs out of filament
and this is a project that's going to take me a while this is a good
time as any to talk about this project no aw crap whatever just roll the title
there you are welcome back there's a reason I'm in my garage and there's a reason
it looks like dexter up in here not me nope so this is a big machine and in the winter here in
seattle gets a little cold the big machine needs to maintain some sort of ambient heat around
it yeah the heated plate gets nice and warm but you know that heat dissipates and if the garage
lets the heat out then models can delam(inate) or or worse right so that's why there's all these
tarps that's why i've got a nice wide angle there so you can take a look at these tarps but listen
this machine just ran out of filament just now uh here let me let me angle you up just
dang it
so if you look there's still a bunch of filament right here.
One of the problems with this machine and what I've been doing with it is that the filament sensor is like a mile away from the hot end and so
look at all this filament right here this is all waste right this is all from here because what i have to do now is snip this and load filament
over there way way back there the problem is I'm now out of 2.85 black filament so I'm gonna have to
use this stuff so here's here's what I'm gonna do I can take a piece of filament and I can
put it into the filament sensor so it thinks it's got filament and then i can hit go up here so
let me do that real quick
ha ha sweet
okay so now because i've run out of filament what i need to do
is manual filament detection. I already have a whole bunch of filament right here and I have
a whole bunch of filament right here so what i'm going to do is get my nozzle back up to
temperature and once it's up to temperature then i can start printing and this will take
10 minutes or so to print and then i can come and switch it out and pause the print it's not optimal
but it's all the filament that i have left that's black and 2.85 millimeter but we should talk about
what this is while i'm doing this.
Not that long ago simon reached. He's @audiosimon on twitter and he offered to design a fully 3d printable speaker for me cool right and
don't worry this doesn't i know that there's polymate3d out there. paul is actually
doing a fully 3d printed speaker itself and this isn't that and i don't worry i've got
that on deck and we're going to be doing that soon but this is a fully 3d printed speaker
enclosure and i'm using this machine and a couple machines at the studio to produce the parts okay
we're almost at the temperature so i'll have to take a break here in just a moment but the idea is
this this speaker these floor-standing speakers i believe have a tweeter a mid-range and a subwoofer
simon is an audio engineer at least i think he's an audio engineer he's someone who can design
speaker enclosures given the parameters a speaker might need and he reached out to
solon.ca which is a canadian audiophile place to get all sorts of really cool stuff like speakers
and speaker components and stuff like that so they're donating the speakers for this build
which is great and this is all filament a lot of it i purchased from FilamentOne
it's good stuff and they were having a great sale so i picked up a bunch of it.
we're at temperature let's start it.
This has been a challenging build to say the least.
I'm using the gMax2 and both Craftbots at the studio and I'll talk about those in a in a later video.
This one though this is the 3DPlatform 300 Series Workbench Pro and I'm printing PLA material from FilamentOne this is all let's see this is at 80 degrees on the bed and it's 210 degrees c on the nozzle
the bed is slathered in Magigoo because i want the adhesion and i'm running into some issues because
i don't know if you can tell it's already lifted from the bed already up here and that's why you
see these kind of inconsistencies right here this machine in all its glory still has some
issues with holding things onto the bed especially when you're printing with giant thick extrusions
i'm using the left extruder on this one and it's fit with a 0.6 millimeter nozzle and I'm doing 0.3
millimeter layer height this isn't the first time i've started this print here you can kind
of see the this is one where it started to get an issue and you can kind of see it right there
the problem was uh it's just it's lifting so if you look at these grills right here because
they're extrusions and they go this direction they want to curl back this way which then lifts
the front off the build plate i've got a brim i've got Magigoo i was like ah crap it's lifting
let me put more Magigoo on and let me jump the bed to 80c maybe it'll hang on and uh it didn't
it really really didn't so i don't i don't know if it's gonna work i hope it does anyway this is
the base there's two top there's a top portion there's a cap and then there's a front and the
front is what i want to show you next there we go look at that it's got a Joelbot on the front
these are the front of the speakers and so they'll kind of go just like that with it
lifting i don't know if that's going to throw off dimensions but this isn't where i started
i don't know if you can tell but that's got a bit of a bend in it right i didn't i'm not using that
large of an extrusion but still things like to curl they like to curl like crazy and it's all i
can do to keep it on the bed i was i was thinking temperatures are what needed to happen but no no
that hasn't been it so this nozzle here this isn't the one that was on the machine it was shipped
with another nozzle which is great because this one broke so while i was printing one of these
the filament started to lift off the bed and it got in the way of this and it started
to drag it around and then it got caught on something and then no joke the filament snapped
the hot end it just snapped it in half [snapping sound] I couldn't believe it i couldn't believe it so it's right
right at the heat break it just kind of it was kind of going around it went *PONK* and it just
popped right off that was a low point let me tell you but eventually i added some brims and even
though it lifted just a tiny bit those brims held it down i leveled the bed everything's good and
so now we have this oh man this is almost done but thankfully i've been running my gopro and i ran it
for the last i don't know seven days so we have a time lapse i hope it looks good let's run it
that was a great time lapse wasn't it it's crazy that the gopro can record for so many days in a
row there were pauses and eventually i would i would come down here and swap out the filaments
and then it would get to printing again according to the display one hour 58 minutes left i don't
know if i have enough to carry it but i'll i'll do my best fingers crossed six hours later so at
this point the print is done bed's going to be cooling down it's 80c wow it's hot so it looks
like uh what i was able to do was uh let's see i used three of these i think three or four now
i don't even remember i just set a timer on my phone each one took roughly 25-30 minutes to
go through this is going to be warm for a while we might be able to to convince it to pop up maybe no
no not at all okay we're gonna let this cool down then we'll pop this off we'll see what it
looks like later it's cool uh according to this we're at 29.5 degrees c magikoo should release
come on
oh it's still REALLY REALLY hot right here wow i don't know if it's because it was
oh crap
let me come around the other side
uh it cracked
it cracked getting it off the build plate i used Magigoo wow it's like all the heat is
just concentrated right here holy cow that's hot that is hot okay well regardless this is now off
yes it's broken at the bottom and let's let's uh take a look around here we go look
this is it i mean it's it's okay right you can kind of see the name right there look at that
designed by Simon Ashton well listen so one last thing to do is to uh is to test so i'm
going to use one of these failed prints so it has registration marks here and there's registration
marks on the piece it did lift a little bit so i don't know if it's going to line up
here let's do that that way you can kind of see it okay it looks like
um because of the lift i might need to shave it down just a smidge i think but essentially
oh wow it's tall this is how tall they're gonna be speakers here there'll be a subwoofer in the back
and then uh that's where the that's the base hole i like my base down low right
well let's see what did we what did we learn today we learned that the filament runout sensor
on this machine is too far away and it results in a lot of potentially wasted filament we did
learn that what we could do is trick the sensor by shoving a small piece of filament into it and
then manually monitoring it that actually worked out okay we learned that failed prints can cause
a lot of damage to a machine especially if the hot end gets caught and then snaps off
that sucks we also learned that it takes a bit of effort to get a temperature an ambient temperature
maintained in a partially insulated garage wow some of the people had suggested that i
go to a home improvement store and get one of those sheds and then i could put the shed in here
and then i could move the machine into the shed we did learn that not all prints are optimized for
this style of printer this thing right here this piece it's the whole head is fantastically heavy
and the mechanism uh just brings it up on two stilts and so if it's doing some fast y movements
it's just gonna vibrate back and forth and obviously the longer the stilts the more vibration
there is so i think that this machine isn't really meant for detail work it's meant for more larger
prints i would imagine or i could just slow it down way down as it gets higher
that's always an option well part one of the speakers are done i think that this is fixable
i didn't know it was holding on to the heat i swear i know Magigoo releases when it gets cold
the rest of the bed was cold the thermistor said it was cold and so i was like what's going on i
had no indication that it was so hot under there that was nuts there's a lot of guesswork in this
machine um and having a glass bed i don't know there must be a better way to do a bed for this
machine maybe something that could hold on to the material mechanically in part two you'll get to
see what the print from the gMax looks like and the prints from the Craftbots and then
hopefully part three is assembling and test assembling and test well i mean a big thanks
to Simon for designing this thing i hope i'm doing you proud thanks to solon.ca sold up in
canada they're the ones that are providing all the components to make it sound really awesome
thanks to FilamentOne for some fantastic filament i'm glad you had it on sale because i just bought
a whole bunch thank you thank you 3DPunlimited for this machine and it's usage um i know it's
just on loan but i'll see what more i can figure out to do with it listen if you made this far
you're awesome i hope to see on the next one don't forget each other more from a safe distance
high five
