DIYs CNC IO shield Ver 1.0 (KIT)

The CNC shield Pin out Ver 1.0 For Arduino UNO R3

for driving with other stepper motors controllers

The KIT includes all parts

You need solder and a soldering iron

• Compatible with grbl 100%
• Compatible with all grbl firmware versions, with jumper choose version to use

J15 & J16

• Two outputs for router and cooling system to use external circuitry with PWM setting or driving a laser with volume control if the firmware is Grbl v0.9j or later.

J7 Router: DIR signal , +5V DC, GND, ENABLE signal

J8 Cooland: +5V DC, GND, ENABLE signal

• With extra in 5V if you feel it is necessary with an diode arduino protection
• Probe connector

+5 V, GND, PROBE signal

• 3 Double inputs for Terminal Switches for Y, X, Z with a filter
• 4 inputs for Abort, Resum, Hold, E-stop (Push Button Switch)
• Dual output for driving parallel to two stepper motor (motor driver) step & direction pulse for axies X ,Y , Z

GND, DIR signal, STEP signal, ENABLE signal

AXIS X, AXIS Y, AXIS Z

• Synchronization cnc step pulse with limit switch. (*1) for all Χ , Υ and Ζ

Y1 : signal , Y2 : signal , IN : STEP signal

Synchronization cnc step pulse with limit switch

Setup for the firmware I will use

For version V0.8 and smaller
PIN11 from the arduino is used for Z AXIS LIMIT
And PIN12 for Spindle Enable (Router)

For version V0.9 and higher
PIN11 from arduino is used for Spindle Enable (Router) with PWM
And PIN12 for Z AXIS LIMIT

<= Ver 0.8 limit SW

>= Ver 0.9 limit SW

>= Ver 0.9 Spindle Enable

<= Ver 0.8 Spindle Enable
