Biqu B1 Random over extrusion in the middle of a print.

[mad_06]

It has only been two months since I got my Biqu B1 and recently I have not been able to finish any print.
In the beginning everything seems normal. But suddenly the printer decides to drastically increase the extrusion motor steps. I pause the print, go to settings, and extrusion motor steps are still 96. I change them to 95, save, unload, and still the extrusion motor goes double what I asked the printer to unload. Instead of unloading 5mm of filament, the printer unloads much more.

The first time this happened I turned off the printer, started from the beginning and the print finished OK.
But now I have tried three times to finish one print and this problem happens again and again. Every time at a different moment. I tried another different print. Again the same problem.
