Can anybody help.At first: Sorry for my bad english. Hope you understand.Now I have to familiarize myself with Arduino. I've been searching in the code for many days, but I'm stuck. I want to count the holes drilled with each drill bit and store that in the EEPROM. For this I need a function that keeps counting when the Z-height is less than 0. The stored values should then also be available via the menu. I have 8 different drills in the magazine T0 to T7. In the future possibly 12. I have no idea where to start. And my C++ skills are not the best.Please help.Best regardsTomm
