Yes, get one of those magnetic screwdrivers that can pick it up or any type of magnet that will help you lift it out. Love Chris

With the help of another person - turn the machine up-side-down.
It worked for me !!

both suggestions below me do work, I know, it happened to me once too....So give it a try

Can you see the screw? Seems like bottle noes pliers might be able to reach down there and grab it.

Oh no. I would suggest to take it to the dealer if it does not come out when you turn the machine upside down. It is only a 5 minute job for them. Hugs

It might be possible to rest the machine on its side & unscrew the bottom enough to shake it out.If it is rattling around on the inside & you can't get it out ,what about just leaving it there & find another screw to replace the one you lost .
I lost a broken needle inside my machine which I couldn't get out & the machine worked perfectly.

Before I would make the drive...I would call the dealer/repair man and ask if it will matter...and if you can just get another screw for the needle plate. I have heard that Baby Lock makes the base of the machines so that if you drop a needle through the needle plate, it should fall and rest at a place that will not matter to the function of the machine...may be the same for the small screw...anyway, it can't hurt to ask...good luck!

Probably need to have a service guy get it out. Not wise to use a magnet if it is a computer machine. That would destroy it. Been there and did that..I use something to cover the opening while I put the screw back in.

Thanks everyone for your input. Sent my dealer an email today and 1/2hour later I had a reply.
He said to take off the end cap. Which I did, looked with light, couldn't see anything, tried tipping it a little but too heavy for me to handle by myself. Got hubby to come and he looked and then tipped it a bit more than I had and gave a little bit of a shake and wahlah! It fell out!
I did the happy dance (but sitting ).
This past year has been rough! I did no sewing of any kind for over 3 months. Then tried and managed to do very little. I now feel much better and wanted to do some embroidery but figured after the machine has pretty much hardly used for so long, that I should clean under bobbin etc. And then ended up with a loose screw!
Now I can get busy! Yay!

So pleased to hear you contacted your dealer and got advice from him. Glad it was a successful. I dropped a needle down the needle plate on my Janome 11000 a couple of years ago. I tried unsuccessfully to tip it out and managed to get it jammed and had to take it to the dealer. A 5 hour+ round trip. I learnt my lesson. I now cover the needle plate when I am changing a needle.

Try a telescoping magnet for picking up things in awkward places. You can get that inside your machine.
