on today's Makers Mmashup part one of our DIY core XY build series so today is gonna be day one of
our DIY core XY build series now this is the lair fused x 301 printer that was developed by Nick
Hogg art and myself and we're going to be going through the electronics enclosure and the frame
today building that from the ground up and then in future videos we'll be assembling the rest of
the printer now down in the description you'll find a full bill of materials for this project
as well as other helpful resources to help you build this printer and if you are interested in
this printer want to learn more there's a card at the top that will get you to the introduction
video that will certainly help you source your parts and learn about what you're getting into
in building this printer so when building the frame today I want to cover what we're gonna
be working on the frame design here goes ahead and uses a solid metal build plate I picked this
up at a local manufacturing place where they sell called metal supermarkets and they sell
metal plates like this but you can get plates like this at your big-box store as well this is
what the foundation of our electronics enclosure is going to be so we'll be able to drill holes
into this plate they'll be stood off here by these TPU feet that we printed those are all
included in the models and then we're gonna use these at the top it's the only 3d printed part
of the bottom base and that's actually at the top not the bottom and then what we're going to
use is the 2080 here to create the bottom and then we're all gonna have our 2040 extrusion for some
uprights near the front and some 2020 extrusion as part of our base and it will also be in the
rear of the printer as well hooking into these 3d prints so if you need help with this you can
always check out our discord and don't forget to subscribe so that way you don't miss any of the
upcoming videos of this build series and with all that said let's get to work today's build
really focuses on the frame itself we're gonna be drilling holes in that metal plate and then
we're gonna assemble the electronics enclosure and after that we'll attach the frame uprights
install the bottom plate and feet and that will add the top framing after that we'll install
the pulley towers and then wrap everything up by installing the stepper mounts if you have
everything ready to go this part of the bill should only take a couple of hours to complete
we're gonna start here by using the TPU feet as a guide for marking the holes that we need
to drill in our aluminum extrusion now you can see here I'm just aligning this with the corner
and once I do that I'm using the pencil here to mark the corners and we're gonna do that on all
four corners you're also gonna use this guide to mark one center hole in the center of the plate on
each of the four sides this adds some additional stability when we screw everything to the base
now I'm going to use a punch here so it makes it easier for the drill bit to grab onto the
metal plate for each of the holes now we're just going to use the drill press to put some
holes in you can use a regular hand drill for this as well I like the drill press because
it makes it a little bit easier to do all the repeat holes now we're just gonna want to use
a file to file down any of the rough edges left by the drill you want to make sure that you get
this pretty flush and it should only take a couple seconds with a hand file and this will allow the
base to be pretty solid and it will add to the overall structural strength of the base itself
now we're going to use these inside corner brackets to assemble the bottom
and Electronics enclosure and you'll need the grub screws that come with it as well
those would be used to hold everything together from the inside corners you'll
find everything goes a lot faster if you pre assemble these corner brackets before you try
to install them on the extrusion now we're just going to insert these into the 20/80
extrusion and then you're going to connect all three of the 20/80 extrusions together
once you have all three pieces of the 20/80 put together you're gonna want to use the 20/20
extrusion and you're gonna put one on the top and this will fit on the inside of the 2080 extrusion
once you have this first one in you're gonna want to flip everything over and then you're gonna want
to repeat the process and install another piece of 20/20 on the top here as well now the reason
we use 20/20 here instead of another piece of 2080 was so that way the electronics and wires
and cabling can all feed through there now we're going to work at attaching the upright pieces in
the back this is some 2020 extrusion and you're gonna want to use one of those inner corner braces
as well you may have to reverse the grub screw on it to make it work for the back of the 2020 going
up as you can see here but once you get this on line you're going to want to tighten this up and
secure it and then after that you're gonna put the 2020 on and this is going to add some additional
stability to this upright going up the back of the printer now we're gonna go ahead and attach
the bonding plate the upright here and this just uses the screws that come with the bonding plates
and links for all these are in the description once this is all tightened up then you're gonna
want to repeat the same process and install the upright on the other side of the printer
now we're gonna measure 180 millimeters from the edge of that back upright that we put into place
so if you just align the ruler in there and measure 180 you'll be exactly where we need
to install the 20 by 40 uprights once you have the bonding plate in place you're gonna
want to tighten it up and then afterwards you're gonna want to put another bonding
plate attaching this 20 40 in the opposite direction once this is complete you're gonna
want to repeat the process on the other side for the other 20 by 40 upright once you have
all of the uprights attached you're gonna want to turn the printer on its side and then we're
gonna work on attaching the TPU feet to the bottom of the base plate and we're going to
then also attach the base plate to the bottom of the printer you're gonna want to go ahead
and insert all of the screws into the bottom base plate before trying to attach it to the
bottom of the printer once you have everything lined up and all of the t-nuts are facing the
right direction then you're gonna want to attach the plate to the bottom of the printer and begin
tightening everything up it may take a little bit of wiggling and in some cases I had to tap
the end of the base plate with a rubber mallet to go ahead and adjust the plate so everything
would fall into place but everything will fall into place it just takes a little bit of effort
now that we have the printer upright we're gonna go ahead and prepare the 3d print to go ahead
and attach that to the printer now we're punching out these sacrificial layers and they're designed
so that way they do punch out it's not a flaw in the design it's so that way you don't have
to have supports when printing these prints out once you have the holes all cleared out
then we're gonna want to go ahead and drop the m5 screws into the two pieces that will attach
the extrusion from the bottom and then we're gonna also drop some m5 screws and some tea nuts
into this part of the print as well and that's going to attach to the 20:20 extrusion at the top
now we're going to slide the base on to the 2020 extrusion and then you're gonna want
to make sure that it is flush on the inside so that way it's meeting up with the channel itself
then you're gonna want to tighten everything up and repeat the process for the other side
now that we have both prints in place the next step here is that we're going
to be attaching the 400 millimeter long 20 by 20 extrusion these slide
into both channels on each side and then after you've got them slid in
and the t-nuts aligned you're gonna drop that in place and then tighten these up
now that the rear one is in place we're gonna go ahead and attach the side rails now each one of
these slides in the channel the same way that the rear one did so you're gonna may need to make sure
that you line up those t-nuts once that side rail is in place then our next step here is to go ahead
and attach the bonding plates here between the 20 40 and the 20 20 extrusion and that will add
additional strength and rigidity to the printer and like the other one we're gonna go ahead and
add two bonding plates here to the twenty forty one facing the other direction once you finish
this side you're going to want to repeat the process for the other side of the printer now
we're gonna attach the right and left towers you're gonna need an m5 by 12 millimeter screw
and three regular nuts now these m5 nuts press into that bottom part of the tower and then what
we're gonna do is drop screws in through the holes in this part and we're gonna attach the right and
left parts of the tower just by screwing it in and those nuts should draw up you want to make
sure that your screws at least a 12 millimeter long screw if it's a little bit short you can
use a longer screw in here as well they just stick out from the bottom last but not least we're gonna
insert some m5 screws in here and what we're gonna do is now attach the stepper mounts these
just slide on to the end of the 20 20 extrusion and once you have those slid on all you're gonna
want to do then is tighten them up and then do the same thing for the other side and that's it for
the frame okay so I think we had a really good build for our first day here we have the frame
fully assembled here as you can see here we've got a very sizable electronics enclosure that's
included in here and we owe all that to the 20/80 extrusion that we put in here all of our feet are
in place here so our TPU feet have a good solid base for the printer it feels very solid we've
got the rear towers are now installed that's what these are called here are the rear towers for the
idler bearings and we'll install those when we get to the carriage and then we also put the stepper
mounts in today the nice thing about that is this looks like a 3d printer so we've made a lot of
really good progress on it and I'm very excited so one thing you're gonna want to do once you
do finish the Assembly of the frame is go back and make sure that all of the screws are tight
a lot of times what happens is as you're moving the printer around as you're turning it over to
get all these pieces in place some of the screws do get tight or there's always a chance that you
might not have tightened one so go back now before the printer is fully assembled and make sure that
everything is square and everything's tight this is really a critical stage of the printer as this
frame is the foundation for everything else that we're gonna do with this printer going forward so
down in the description you should find a bill of materials for this and there will be links to the
3d printed parts that are going to be available on Thingiverse now one thing to note that as the
series is still progressing you may not find all of the materials in the Bill of Materials or the
models that will go on as the series progresses I'm using the video series as kind of the final
QA of the parts and the links to all of the different parts in the bill of materials to
different vendors that have this so if you don't see a part in there I know those are coming so
just want to let you know they will be coming as the video series progresses but you should
have everything in the description and the bill of materials to follow along this far so if you need
help building this at all there are links down in the description to our discord and that is just an
open makerspace where we talk about all sorts of different things it's community based so you'll
get help from any of the people that are online at the time it's not really technical support but
more of a community and that community can help you get this printer or any other project that
you're working on put together and worked out if you'd like to help support this project or
the channel as a whole please consider becoming a patreon member patrons have exclusive access
to resources and content that can help you with this project or other projects so it's a good way
