My NECCHI SOFIA 300 sewing machine has recently developed a fault whereby it intermittently continues stitching after I have lifted my foot from the pedal. The stitch itself is perfectly formed.

Try putting a small drop of oil on the the metal shaft of the bobbin winder if it is not moving freely. The grinding noise implicates the winder tire may be ground from the locked winder shaft. The needle not disengaging requires oil in the shaft bushing. On this machine it appears you would have to remove the covers to access the appropriate areas.

Depends on your machine, but remember if your machine has a 5mm needleplate opening, that limits the size of the lettering you will be able to produce. Unfortunately, to get larger output, you would need to upgrade to an embroidery machine or do the lettering manually with a satin stitch. You can, after practicing, do monogramming free hand with your machine and a satin stitch. However, remember, if the stitch width is limited, even satin stitch will still be limited by that stitch width.

I'm a bit confused, this isn't a serger machine as far as I can see. So do you mean an overcasting foot where you sew a XXXXX type stitch along the edge of the fabric? The overcasting foot just helps you to line up the fabric edge and sew over it neatly.

if you go to this page http://www.sewingpartsonline.com/necchi-6022-sewing-machine-parts.aspx
there is an instruction manual for sale.

http://sewmamasew.com/blog2/2009/06/feet-feet-feet/ is also a great resouce on sewing machine feet with good photos of what they are used for.

Here is a video of overcasting foot in action http://www.sewingmachine-sales.co.uk/sewing_machine_info/video/34/adjustable-overcast-foot.html

If you are wanting to sew knit fabric then you just need to use a small zig zag stitch and a ball point needle to put elasticity into the seam. Or your model may have a stretch stitch, where the fabric is moved forwards and backwards during the stitch formation to add some elasticity.

Sewing elastic stretched onto fabric is a bit different with a SM, can be fiddly and hard to keep everything lined up nicely and stretched. Some machines have a little device which clips onto the needle plate in front of the needle that you can feed elastic through and tighten it to tension it, then just use a three step zig zag stitch to seam over this onto your fabric. But I don't know if Necchi has such a thing, your needle plate would need holes in front for it to clip into. Elna had these on their swiss machines in the 80's but haven't seen a similar device for a while.

Hope I've answered your question and not completely misunderstood your problem. Purchasing a manual is often the best way forward when a machine is unfamilar. Or www.sewing.about.com is great resource.

The tension is not changed.

You lower the feed dogs, or change the stitch length to zero and cover the feed dogs by taping an index card (make a hole for the needle) over them.

Be sure to use a darning or free motion foot and have the presser foot down when stitching.
