I'll just start off by saying, I'm a complete idiot with this... Spent yesterday afternoon and most of today, to only realize the SD card or reader supplied with my Ender 5 was bad. Was finally able this evening to get the Sonic Pad to connect to my printer. I'm now having issues getting it calibrated... I've adjust the prior settings with the paper provided but when it does it by itself, for some reason on the left hand side of the bed, the sensor is over and the head its the board and it faults out. I've adjust the board like crazy and over compensated but I can't get past this stage... Please help an idiot out
