Machine embroidery needle changes position

truthfully I think their something wrong with the computer in the machine because
the bobbin locked up. sometimes when a sewing machine jams it can make
the machine jump time.
but the needle moved positions, some part of the machine is changed during the
jam up, even tho you reset it.
embroidery machine are expensive, my suggestion is to have the machine checked

Needle/hook timing is off

1. Remove bobbin case 2. Unthread machine 3. Replace needle making sure it is all the way up in needle shaft and tighten screw 4. Set for straight stitch sewing 5. Position needle bar at Center 6.Roll up a towel and gently lay machine back on it. 7. Remove shuttle race ring 8. Turn handwheel SLOWLY toward you until needle reaches it's highest point and travels just 1/16" 9. Point of hook should be directly BEHIND the needle OR At LEAST 1/16" or tad above that measurement. 10. As hook passes needle, it should be slightly ABOVE the eye of the needle If timing seems good at this junction, you can carefully wipe the hook with alcohol on a clean, lint-free cloth (old T-shirt makes good rag) MAKE SURE YOU ARE CAREFUL BECAUSE HOOK POINT EXTREMELY SHARP! ALWAYS SET POWER SWITCH TO OFF POSITION/UNPLUG -- Never panic or toss machine across floor because you can probably determine that it's just a matter of rethreading or a minor adjustment. Hope this helps! Jimmy

I was sewing, turned the machine off to pin something, and when I turned it back on, it jammed in the bobbin area. It will only stitch one stitch and then jams. I have taken it apart over 30 times, and...

have you tried changing the needle-
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
check the thread take up lever-if the thread come off the thread take up lever that will jam the machine up--I've had it happen to me

I was trying to sew fleece and the machine started jamming and I cleaned out the bobbin casing and also changed the needle and it still jams.

correct needle insertion is mandatory for the proper use of the sewing machine. Raise the needle bar to the highest position, then loosen the clamp screw to remove the old needle. place the new needle in the clamp with the flat side of the needle facing the back of the machine. or if your using a round needle the groove in the needle should face away from the shaft.push the needle all the way up to thestop or as far as it will go & then tighten the screw

also if the thread comes off the thread take up lever it will cause the machine to jam up-i've had that happen more times than I can count

also clean under the needle plate for lint

Adjusting the timing of the thread trimmer cam

How to adjust the timing

The timing of the thread trimmer cam for cot ton and synt hetic threads can be obulned simply by aligning the marker dot on the machine ann and the marker dot on the handwheel.

Till the machine head. manually tum the handwheel un til the thread take-up lever almost reaches its highest

position . and press th read take-up picket to the right by finger. This causes the earn toller 10 fit

in the groove of the thread trimmer cam. With this condition maintained, tum the handwheel in the direction

opposite to the nonnal rot ational direction . and you will find a position in which the handwheel no longer

turns. Then, adjust the cam timing so that marker dot on the machine ann is aligned with

marker do t on handwheel This provides the proper cam liming for ca tion
and synthetic threads.

Have a brand new Singer 1507 that keeps jamming the bobbin thread. Have followed threading and winding bobbin instructions closely, but am still having problems with the bobbin thread jamming after 1-2...

I would try adjusting the tension on the machine - this sometimes causes the bobbin thread to jam while sewing. Re thread the entire machine including the top thread. Also it is recommended to use new thread as old thread can ball up after time. If no luck I would call the store you purchased the machine from.

Bobbin mechanism is grinding and seizing up

What you are sewing may be too much for the type of sewing machine you are using.

It sounds like you should use a larger size needle.

The problem with the bobbin could be the thickness is such the presser foot is not down to the position it should be to engage the tension.

When the presser foot is lifted, the tension control opens.

Thread the machine with the presser foot up so the thread can "seat" into the tension control, then try sewing two layers of a thinner fabric to see if there is still a problem.

When you stop sewing to adjust the fabric, make sure the needle is down to hold the stitch in place as you make the adjustment. Movement of the stitch when the needle is up will sometimes cause the thread to jam in the bobbin area.

If the problem continues, the machine may need to have the timing adjusted.

If you are mechanically inclined, you can try this adjustment. Graphics and instructions can be found or take it into the shop for service, which usually begins at around $80. This could be more if you take the machine apart and then cannot get it back together.

My needle jams when it hits the tray the bobbin case is in. It looks as if the timings off because just to the right of where my needle hits is a dip in the tray. Almost as if the needle's too long. I've...

If this is a drop-in/horizontal bobbin, raise the needle to it's highest position. Remove the bobbin case then replace it so it fits snugly into the shuttle. Hand walk to see if the case moves freely in a circle. If it stops, it is not positioned correctly. You do not have to have a needle in to test this.

Once you are sure the bobbin case is correctly in place, re-install the needle. Hand Walk to make sure the case turns without any interference.

If the needle continues to hit, then the machine needs to go into the shop for service.

There is a DIY for adjusting the timing of the hook if you wish to try the adjustment on your own.

The needles are changed by inserted the hex wrench into what looks to be holes on the front and left side where the needles go into the machine.I'm not sure what size the hex wrench is but it's pretty small. From the manual,
"Removing Needle: Unplug the machine. Turn the handwheel counterclockwise to raise the needle bar to its highest position. Loosen the needle clamp with the allen wrench and pull the needle out." and
"Inserting needle: When the neddle bar is at the highest position, insert a new needle in the needle holder, making sure that the groove of the needle faces you. Push the needle as far up as it will go and tighten the needle clamp screw." "Removing Needle: Unplug the machine. Turn the handwheel counterclockwise to raise the needle bar to its highest position. Loosen the needle clamp with the allen wrench and pull the needle out."

The machine takes DB x 1, or 1738 needles, and a size 14 needle is recommended.

Hope this helps!
