We recently had a case where connected proximity sensors just didn’t want to run, well, they needed a little more voltage than the printed 5V. your spindle, water pump or laser, you need this current, which is usually higher than what the Arduino can tolerate, because it can only be 40mA per connection or in the sum 50mA, which means that if I switch on 2 LEDs with one output of the Arduinos is already over, because more is not safe to operate. The Arduino then „thinks“, eh, the end or fault switch is activated and the machine simply stops and then the work is lost.īut what is even more important, if you want to switch thick relays in order to switch e. they can occur when the light or washing machine is switched on, or simply for no reason. On the one hand, interference voltages can be effectively prevented which can occur despite the presence of mains filters and capacitors, e. There are several reasons for using optocouplers. 0-10V output for frequency inverter (adjustable).Output for switching a relay around a milling motor.Sensor input (touch plate, length sensor, stylus can be connected in parallel).Limit switch X Y Z (front and rear, 6 in total).Motor driver Dir X Y Z also includes multiple drivers per output.Motor driver Step X Y Z also includes several drivers per output.The control card has the following connection options: The request form can be found below in the text.Īs a heart beats an Arduino Nano 5V V3 whatever else we are the ArduinoClub. The ArduinoClub has developed a CNC Controller which harmonises 100% with the known Cam Software Estlcam and is controlled by Windows 7/10 with USB.
