I ended code for sender esp32 (I’m using esp NOW communication) and start checking if the CAD project have some inconveniences, and it has a lot. First the spear for beads wasn’t the right size and form, so I fixed this. Second button wasn’t fitting in the mold for it so I also fixed it (it’s visible on the front of casing). Third, I added holes for motor controler casing. And fourth I added hole for powerring circut from the electrical outlet on the lid of the casing. Tommorow I will end the CAD and AGAIN writing the code for reciever of esp32.
