Suggesting to a customer to fix the equipment or to try to find the cause of an issue is in fact bad business model IMHO. This board is not even three month old and as I mentioned previously it is my second one because the first one puked on motor 4 port. All I know I will not waste my time anymore trying to cloud folder and parameters dump and oscilloscope or to fight with gcode beacuse TinyG lost serial port in the middle of a job. or a motor port simply quits never to come back etc.
There is an old saying – scrooge will pay twice. Yeas, it is about me, I was hopping to have this simple and relatively inexpensive solution which tuned out to be a time and money consuming monster.
