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
