A low cost diy mill cnc. The original idea was create a mill cnc to create my own pcb's (naive of me).
- Easy to mount
- Mostly 3D printed parts (better as fewer different parts be) (5 differents 3D pinter parts)
- Standard and cheap material to buy (it's why I don't use an aluminum profiles)
- Dremel as mill machine
- Basic electronics easy to buy and cheap one's
- Standard stepper motors, NEMA 17
- Total price lower than 100€ (wish)(excluding the Dremel machine)
Presition for mill PCBs- Milling material: wood,
cooper, aluminium - Open source code (as Marlin)
- Work surface
> 10x10x2cm17.5x13.5x2cm
| Qty | Concept | Estimated price |
|---|---|---|
| 1 | Arduino Mega | 5€ |
| 1 | Ramp1.4+LCD | 20€ |
| 5 | Stepper motors NEMA17 | 35€ |
| 2.5-3m | Calibrated rods 8mm | 9€ |
| 50cm | threaded rod | 3€ |
| - | Bearings, gears and some screws | 8€ |
| - | Gear belt | 2€ |
| 1 | Coil of PLA (or what you want) | 25€ |
Must change the following points:
- ...
- Low rigidity (specially in Y axis)
- Backlash as old 3d printer
- Low movements (as expected)
- Poor rpm control (as expected)
- Dificulties to calibrate well the Z axis in all plane
- The work surface must be higher that machine suport, and there's not easy way to subject objecto to mill without use screws
