Then machine went crazy, I could stop it only turning it off. My embroidery stuck as the main thread were in the needle plate. I cleaned bobbin compartment, changed needle, was trying different tensions for the upper thread, but unsuccessful. Please help me to solve this problem.
Are you still having these problems? First thing that comes to mind, since you've embroidered 1 project successfully, you might need to replace the needle, and open bobbin area--remove lint & dust. If you're using the exact same thread (same spool) but wound a new bobbin, is it wound properly? it should be even & smooth on the bobbin, no lumpy areas, and also--not too full. If you're using different thread--you should always make a sample when using different thread. Fabric & stabilizer choice--- are you using different fabric & stabilizer?
These are same basic questions & issues to resolve as for regular sewing. The embroidery machine worked well for you the first time-- so it is very likely that the needle, thread choice, fabric/stabilizer choice, bobbin are the cause of your issues. I didn't get into tension since I don't know the Bernette machine, but that also could be the issue.
To top it off, it might not just be 1 thing causing the issue, but several things. So, keep a little notebook and whatever you change, write it down. Pretty soon (there are only about 6 or 8 variables) you will hit on the right combination for your machine, thread/needle/fabric/stabilizer/tension etc. If you had a notebook already and written down the successful combo from your 1st design, the machine should produce similar results (assuming threaded correctly, and perhaps no little fingers came along and messed with the settings). Keep playing detective---and in the process you will learn a lot about how the variables affect the outcome.
