I received today my pre-assembled Prusa. I followed the flowchart and "calibrate Z" and instead of printing Prusa logo, I printed V2Calibration (even though this was pre-assembled). I remember the first time it was perfect. In the afternoon, I wanted to show the printer to someone during calibration, so I did calibrate XYZ. Here are the mistakes that I did:
1- I did not read the instructions on the LCD and did not put a paper under the nozzle (I did not hear any loud noise of nozzle hitting the bed, so I hope that is fine)
2- After calibrating 4 points, the printer does another 9. It was taking long and I could not cancel it, so I turned the power off.
After that, I did the prusa logo and I was seeing there is something wrong with the first layer, but I continued. I left the machine during the print and when I came back I saw that the print stuck to the nozzle and it failed the print. I removed the failed print and tried the V2calibration again. This time V2Calibration is not with straight angles. I did "selftest", "Calibrate Z" , "Calibrate XYZ", bed elvel options and they all say it is calibrated. But, with multiple try, I still have problem with "first layer calibration". Please help
