- I have a 3D printer or will be getting one before March 21st
plan: make a 3d printer capable of at least 400mm by 400mm and 600mm height 3d printing and be able to print over the internet, (and i want to use ethernet) this will be useful for printing 3d printed plane wings etc and big things, those are basically my criteria
Log :
Total hours so far: 97.5
Sunday, march 2nd
7 hours
research, looked for parts and worked on a BOM and started looking for cad models for onshape
Monday, march 3rd
6 hours
looked for more parts, BOM is close to being done and im trying to find ways to cut costs because im going overbudget
Tuesday, march 4th
6 hours some more reasearch, i started looking into how i could save costs, i also wasnt sure how i was going to connect the extrusions togheter so i looked into that i did some research on how i could design the heated bed pcb myself
Wednesday, march 5th
7 hours i designed the heated bed pcb
thursday, march 6th
7 hours
i continued the pcb and then i did some research to look for other websites where i could get parts for cheaper
heated bed pcb schematic:
sunday, march 30th
5 hours started the cad and looked for ways to make the bom cheaper, i found some deals
monday, march 31st
2 hours worked on the cad, mostly on making the t slot nuts and extrusions fit togheter and the screws too
tuesday, april 1st
2 hours continued the cad and got one adapter done, also started to get the hang of using constraints
wednesday, april 2nd
2 hours continued the cad
thursday, april 3rd
10 hours
i have a decent part of the base structure done in the cad, also bom is pretty much finalised
friday, april 4th
10 hours
2 days left
this is the 3d model of the pcb ill import into onshape, dw i wont order it green, im ordering it white or black
for future self:
remember the two holes should face outwards
because they are the holes for the wires as you can see here
this is important because in the cad i dont have any other reference:
just found out “drawings” exist, these could have saved me a lot of time and struggle lol
especially right now that i am trying to design some wheels that will fit properly in the cad
also added a bit to the bom
saturday april 5th
7 hours
the printer is starting come togheter and look like a printer!
then i also started working on the z axis aka the moving bed assembly
sunday april 6th
7 hours continued designing the printer, did some research on how the corexy system works because at first i was going to have one sationary motor and one that sits on the toolhead gantry but then i saw a short yesterday where both where stationary and i realised that using some sorcery you can have no moving motors exept the extruder one
monday april 7th
4 hours i finalised the pulley and belt system the cad is basically done and i could now build the printer
i also added the cad files and the kicad pcb files to the repo
note to self: my wood scraps are 8.75cm by 3.75 cm aprox my screws are: 6 , 1 1/3
(i plan on building some support to hold the printer by the top out of some wood i recycled from an old project)
rest of april update:
15 hours
worked on my printer mod started planning a redesign. Because my goal with this printer is to have large volume printing with little regards to speed and not much about precision the reason for that being that i plan on printing large rc plane wings, i figured itd be better off with a robotic arm 3d printer. I’m going for 1.2m reach with this and im gonna use brushless motors along with my own foc esc with encoders ill make using onboard live. this should allow me to print even big single wing planes!
may 3rd:
0.5 hours Received the heated bed pcbs from jlcpcb! i tested them and the calculated resistance of the tracks was only off by 7%! And they heat up pretty well!
