I look back to my old dusty K40, while my ESP32 are in the slow boat…
About 6 years ago, when modifying my K40 with a smoothie board, I had a chat with @Arthur_Wolf to implement a water flow sensor, the result was it was needed to code for the Smoothieware, a step too far on my knowledge, the water flow sensor stay in the box.
Here is the 2021 idea :
What about a water control for the K40 based on flow and temperature?
- a color led ring to show the temp range and where you are in it . (Blue too cool range, green operating range, yellow dot actual water temp, red too hot range)
- auto switch off if under flow speed or over temp threshold (all k40 or just laser interlock)
If the piloting software is open too it, it could display message on your screen like “close the door to run the job” or “water too hot” (any interlock detected, etc …) This thing could be possibly extended further (remember that: https://youtu.be/arjRtCjI9AQ?t=140) servo (defocus or flip object)
So the ESP32 look a perfect match for the K40 (independent of your controller board), within the low cost K40 philosophy.
- Plenty of hardware compatibility (https://randomnerdtutorials.com/esp32-pinout-reference-gpios/)
- Plenty of Arduino sketch ready made around. (Color led ring, water flow sensor, relay, DS18B20…)
Just a brain storming for now, let me know what do you think about it .
Why not doing it all together as a project community, as we did in the past ? (Nudge to Laserweb or other K40 softwares) @cprezzi
