Re clarification

As I said I'm not going to build this I only want those tickets not a grant ( for 3d printer) because I have so much going on please just give me those tickets 🙏😭

Last touches (hopefully)

- Repo

• Added links in BoM section (Readme.md)
• Included links in BOM.csv
• Implemented the full journal.md
• Improved the README :D

Please reviewer, could I get tickets instead of a grant? I’m in a tough spot with exams and spent all of this week building this CNC. (i really need to lock in)

3D printer here i come (:

Working on modularity

I added a laser module to the machine. Swapping between the milling head and the laser head is really easy:

1.Remove the four mounting screws.

2.Take off the spindle and the 3D-printed front cover.

3.Place the laser module in position and secure it using the four screw holes

4.install the 3D-printed cover.

And just like that. The machine is ready for engraving.

Controlling Grbl_ESP32

I’ll be controlling the CNC through Universal G-Code Sender. The whole setup will be accessible through a Web-UART interface, so I can run it directly from a browser without needing a dedicated PC.

PSU case

RENDER OF BOTH THE CNC AND PSU

this look fire

THE CASE

Made a 3D-printed power supply case in Fusion 360 and mounted it on the CNC. It actually came out looking really good!! I dropped the STL into the repo under the 3D-printable folder so it’s all organized.

some change

PCB

• Cleaned up the layout and added proper mounting holes so the board can be fixed down
• added some arts (m4 and blueprint logo)

Repo

• Made a KiCad folder and added the Gerber files. Tweaked the CAD folder too(screws , brackets and lead screw nut). Also added a new PCB section in the README.md so everything look Nicer .
• added a whole render folder in the repo
• researched a PSU since i forgot about it then added it to the BoM

firmware

the cnc is going to run Grbl _ Esp32 firmware i added it in the repo
added pin configuration ( pins_scdc.h ) in the firmware folder
also added the gerber of the cnc shield from kicad

fixed the repo

made a logo using canva and enlarged the bom then added the price in dollar and mad
made a name for this project, updated the cad file ( SCD-CNC which stand for Super Cool Desktop CNC)

some change to the shield

Added proper 2-pin connector for adjusting the micro-stepping then made 2 socket pin for the limit switch mod. Also added a screw terminal for the big emergency stop button so it can cut the 24V line instantly. Makes the CNC safer and way less sketchy.

made the cnc shield 1

I researched the available drivers and chose the DRV8825 because it handles higher current and offers finer microstepping. I finished the schematic, then routed the PCB. It took me three attempts, but I eventually settled on this design. i will probably upgrade or even change it since i m not a big fan of the layout nor screw terminal this took so much time i know its simple but im not that good in electrical engineering.

schematics

pcb layout

3d view

finishing touches

i made some final changes to the design ( fillets etc... ) also changed the readme.md . Now i can hop onto the next task making the pcb

the final design

bare bone

the 3d printed components

changed the layout

I shortened the frame to save money and i reinforced the Y axis extrusion with a 20mm plate since i changed the whole layout the dimensions now are 469*400mm

plate moving

made the bom and repo

just created a repo for this project added a readme.md , the cad files ( with the full assembly ) and Bill Of Material next task is probably making the electronics

WHOLE REMAKE

I didn't like it cuz it was so small SO i stayed all night making this cnc router thats now modular just swap the head !! its better its bigger and yellow which is also cool. ill make a bom and a repo !

finished the design

after 2 hours i finally finished making this cnc milling machine im so exhausted + i need to recheck those stepper motor and their support . tomoroww i will try to make the controller, the github repo and the BOM

Y axis

Me again I’ve finished designing the platform for the Z-axis, and now I’m moving on to modeling the Y-axis for my CNC mill/plotter project this where i will make it modular

Z axis

made the Z axis structure i just used the same component next goal is to make the Z platform where will be the Y axis and the spindle or the module or whatever ...

FINISHED THE PLATFORM

SO I finally added the platform added the platform everything going well For now hopefully i design the y axis in the next hour hopefully but i would still need 3d models of some component like the spindle , the extrusion etc

Added the x movement

so I designed a 3D-printed shaft-support brackets to hold the two guide rods for the X-axis. They keep the rods aligned, and I’ll add the platform next.

making the base

Hi ! I started by designing the base of my CNC mill/plotter in Fusion 360 , I used 20×20 T-slot aluminum extrusion. The frame measures about 239.5 × 200 mm, and I added 3D-printed brackets to hold everything firmly in place
