Revolutionary DIY CNC Crashproof Router Bed: Say Goodbye to Crashes!

Video Description

Finally complete the best CNC router upgrade you can do! Add one of these systems to your cnc and if the cutter runs into a hold down screw then the machine will go into an emergency stop and probably save your cutter! If you want to program your Arduino then download the programmer or IDE (integrated development environment) from here:- https://www.arduino.cc/en/software/ Arduino general info from here:- https://www.arduino.cc/ Here is the code used on my crashproof router:- /* This Arduino code is designed as an auto E stop for a CNC router This is how it works: Detect a crash (tool touches a metal hold-down clamp) Turn on relay to force E stop (relay isolates the Arduino form the machine) Delay for ten seconds ( time to allow the machine spindle to fully stop) Turn off relay to release machine (holding machine in E stop will prevent you resetting it) Wait for fault to clear Back to start and keep looping through program */ void setup() { //configure pin 2 as an input and enable the internal pull-up resistor so pin 2 is the sensor input and pin 13 connects to the relay pinMode(2, INPUT_PULLUP); pinMode(13, OUTPUT); } void loop() { //read the sensor value into a variable int sensorVal = digitalRead(2); if (sensorVal == LOW) { digitalWrite(13, HIGH); } if (sensorVal == HIGH){ digitalWrite(13, LOW); delay(10000); digitalWrite(13, HIGH); while (digitalRead(2) == HIGH) { ; delay(1000); } } }
