Open box CR-10 V3 and will not auto home. The Z axis continues to move further from the bed each time I have tried to run the calibration. I don't have the BL touch and I don't know if the previous owner had one connected to it. It was an open box item and the $70 I savved certainly doesn't justify the hours of frustration. I have spent the last 30 hours, yes you read that correctly, with about a 2 hour break in the middle trying to find aything about this online and trying to resolve the issue.
Any advice or suggestions would be appreciated. This is my first printer and I am about to throw in the towel all together. Maybe I am just tired. Thank you for any help.
