Could you help me with which machine you used for the melting tool in the middle?

I would like to thank the original creator of this amazing Petalot project for sharing it with the community. It has been a really enjoyable and educational build.I made a small upgrade to my version by adding a 1602 LCD (I2C), which makes it much easier to monitor and control the process in real time.To support this, I also modified the original code to integrate the LCD functionality. I hope this addition can be useful to others who are building or improving their own Petalot.All credit for the original design goes to the creator — this is just a small contribution on top of a great project.Thanks again for sharing!

Hi. What do you mean? I tested some times with diferente temperature's and speed and it’s working great. Maybe 1h in total for the tests.
