Uh oh…. It happened again. It suddenly goes haywire while travelling. I was performing a simple jog back and forth to test my endstops (which worked at first), and then it suddenly stopped moving properly and the endstops have stopped working too. This is looking like a problem with the Arduino. :/
Another compile and upload fixes it again. Let’s see for how long.
Not long… it works for a few minutes then goes haywire. I’ll try ordering a new Arduino Mega.
