It is so different not to have to lift the presserfoot! I have the same probelm.
The 830 does have auto tension when you change the type of fabric you are sewing on. The tech also said the "B" foot was better to use sometimes even if the machine indicated the "A" foot because it allows fabrics to flow under the cut out part at the bottom but I haven't tried that yet.
Glad you are getting used to your new machine. Have a great afternoon. I'ts sweltering here in souther Mass. Almost 100 and humidity is just as high.
