- Material Used:
- Arduino, Oled SSD1306, Flow sensor YF-S201 & DS18B20
I just started some weeks ago into the CNC world with a workbee 1510 and a watercooled spindle.
I was worried about the cooling of my spindle, some of my concerns was :
then I decided to buy some components for less than 10€ to design a small arduino based project to keep those concerns away from me and my CNC.
- forget to start the pump
- loss of flow
- increase of temperature
if the flow is less than 20l/h, the arduino open the relay which cut the loop of the doorswitch input of my blackbox controller,
- Arduino (nano)
- YF-S201 for the flow sensor
- DS18B20 for the temperature sensor
- one 0.96" Oled
- one 5V relay
Result = spindle stop !
when the flow is not active, the Oled shows the coolant temperature.
when active, you'll see the actual temperature + also temp at start & the flow rate
at start, Opendbuilds logo are showned
the code is provided and ready to help if some of you are interested in!
