Introduction: Mini Drill Press
This is my first instructable. First of all, I wanna made a Drill press, but, with my own design. And, a Plus in this case, that had two options, Manual or Automatic.
In Manual Mode: you can move the drill with a joystick in the Y Axis. Step by Step.
In Automatic Mode: You can move the drill with a joystick in the Y axis. But, the drill automatic will returned to inicial position without press the joystick.
Step 1: Materials
First, this is the list of components that you will need to buy or get to do this Drill Press.
1.- Arduino Nano V3.0
2.- Stepper Motor Nema 17
3.- Easy Driver for Stepper Motor.
4.- LCD Cristal 16x2 with potenciometer 10K.
5.- Switch On/Off
6.- DC Female Plug
7.- 12v 2a DC adapter.
8.- Linear Motion 8 mm Shaft 300 or 400 mm length
9.- 5mmx8mm Motor Shaft Helical Beam Coupler Coupling 18mm Dia 25mm Length
10.- Mounting Bracket for Nema 17 Stepper Motor
11.- Joystick Shield
12.- Push Button Shield
13.- Linear Motion Ball Bearing CNC Slide Bushing 34.5mm Length Pack Of 4
14.- 300mm 8mm Lead Screw ACME Lead Screw and Nut. 3D printer Row Lock
15.- Clamps 2" and 1"
1pc. 40cm x 30 cm ( Base Plate).
1pc. 40cm x 7cm
1pc. 40cm x 5 cm
2pc. 30 cm x 7 cm
1pc. 36 cm x 10 cm
1pc. 11cm x 15 cm (for Dremel or MotoTool).
1pc 7cm x 10 cm( for Top for DREMEL or MotoTool).
1pc 40.5cm x 5 cm x 3mm for LCD, PushButton and Joystick.
18.- Screws 1"
19.- Dupont Cables, Drill, carpenter's square, and glue.
Step 2: Build Structure
We need to join the tables 40x30, 40x7, 30x7 and 36x10. for the FLAT BASE.
With the table 40.5cmx5cmx3mm; we have to cut the hole, to put the LCD. And, the hole for Joystick.
We have to put the Linear Motion 8 mm Shaft and 8mm Lead Screw in 90º using the carpenter's square.
Step 3: Connections With Arduino Nano
Let's explain the connectons:
Arduino To Easy Driver
Pin 2 connected to Direction Pin
Pin 3 connected to Stepper Pin.
Pin 4 connected to MS2 Pin.
Pin 5 connected to MS1 Pin.
Pin 6 connecte to SLEEP Pin.
Arduino To LCD
Maybe, some of you have more experience with LCD and IC2. But, I don't want to buy it. so, I used the components that i have.
Pin 7 to d4
Pin 8 to d5
Pin 9 to d6
Pin 10 to d7
V0 to the potenciometer.
VDD, A, Right side of the potentiometer to +5 VDC
VSS, K and Left side of the potentiometer to GND
Joystick To Arduino
+5VDC to +5
GND to GND
VER or VRY to A6
HOR or VRX to A7 (If you want to use it in two axis.)
Push Button To Arduino
S(switch) to A1
+ to +5VDC
- to GND
Easy Driver to Stepper Motor and DC Adapter.
Wires Red and Blue to Coil A
Wires Green and Black to Coil B
GND and M+ to DC Adapter 12 volts 2 Amp.
NOTE: When all the test will be OK, we have to connect de DC adapter to VIN an GND of Arduino nano.
Step 4: Testing Connections
Take Care to don't do a short circuit, because I did it, and I have to buy other Arduino nano.
The Push Button, will change the machine to Manual or Automatic. take care to connecting this.
The LCD used 5 volts, take care connecting the 12v to stepper motor.
Step 5: Code
The Code it's easy,
I used two brainy-bits tutorials:
Thanks for the collaboration of this knowledge..
Step 6: Video
Step 7: Next Steps...
I'm gonna finish the Work, I only need to put the Mototool and the Clamps to hold it.
And adjust the easy driver and the stepper motor, because it has a small wire.
In a few days I'm going to show you the final project.
Thanks for Read it.
