Goodnight! Not long ago, I wrote about a malfunction when the nozzle of my printer was losing support and the print quality was terrible. I found a solution. Maybe it will help someone. I decided to check the belt tension. I downloaded a guitar tuner and adjusted the Z‑axis belt. Its frequency was 103 Hz. I did the same with the bed belt — it was 80 Hz. Using an Allen key, I increased the belt tension to 107 Hz, and the printer started working as it did before!

Good day to all. faced with such a problem. Initially, the printer printed well, but then I had a large order, the printer worked for 12 hours for 5 days. After a short downtime. Literally after that, the printer stopped printing on the previous settings, leveled the table, put a few pieces of paper there so that the calibration values worked better. The situation has improved. However, when printing a part, literally when 70% is printed, the printer starts to touch the supports with the nozzle and tears them off. Help me, I don't understand what to do!
