The material slides all over the place between the pressure foot and plate

Good Day

This question is a bit vague and can have many reasons however basic checks you can do is first make sure there is thread on the bobbin under the pressure foot plate. Second re-thread the cotton to make sure it is threaded correctly from the cotton real right through to the needle, this often causes the stitches to behave erratically. Third if the bobbin has cotton on it, make sure the bobbin is seated correctly in its housing under the pressure foot plate. Fourth make sure that the tension in the pressure foot of the sewing machine is set at the correct pressure for the material being used.
Hope it is one of these that can be the cause.

Kind Regards

We don't know what machine you have, but I'm guessing perhaps you dropped the feed dogs for darning. The feed dogs will still move backward, down, then forward, but in darning mode, they never rise above the needle plate to grab the fabric.

The amount of pressure on the pressure foot can cause real problems. If you lower the pressure on the foot it is likely to work better. If this doesn't work try using another type of material. Some materials have problems because of being slippery or too thin. If this doesn't work check to see if the pressure foot is directly on top of the feed dogs. If it is it will need to be adjusted so that it isn't directly on top of the feed dogs.

The pressure foot is only made to push down on the material, not the feed dogs. If you put it too low it will destroy the feed dogs and the pressure foot as well as the material.
1. To adjust, lower the pressure of the pressure foot as much as you can.
2. Place a thick piece of material under the foot. Turn the hand wheel until the feed dogs are up.
3. The pressure foot rod has a screw that holds it into place. You will adjust the rod by moving it up and down until there is a small amount of pressure on the material. Tighten the screw and try your machine without a needle to see if the material will move. Now, try other thicknesses of material. The rod may need to be slightly adjusted a small amount to get it "just right".
4. PUT IN NEEDLE AND CHECK FOR ALIGNMENT TO THE HOLE. (DANGER IF NOT ALIGNED).

1. It most likely is the foot pressure not set properly. With thick material it needs to be less and with thin material it is opposite. Just test a piece of like fabric that is rags.
2. Make sure that you clean out any thread under the plate as good as you can.
3. Check your tensions. The top should be around four. The bobbin tension has to be even with the top tension. (like tug of war) However, when you thread the top do it with the foot up to check for snags. Snags are a serious problem and cause the material from moving. Good Luck.

Lift the sewing machine pressure foot and make sure the needle is not in the way. Slide the plate under the foot control. Use a flat head screw driver to lift the spring back onto the plate then slide it back.

Are the feed dogs completely up?
Are the feed dogs worn or clogged with lint and yuck?
Is there a presser foot pressure setting dial or knob?
Is the correct foot on the machine?
Is the presser foot correctly mounted?
Is the needle plate correctly mounted?

Can you see the feed dogs moving?

un thread, raise the pressure foot then manually turn the flywheel towards you and watch the feed dogs (the teeth that move under the needle plate). If they are not moving around and coming up above the needle plate then one of two things:
either you've accidentially disengaged the feed dogs, check the manual for instructions to reengage, sometimes a knob, button or slide, often on the front base or around the back of the free arm.

If they are engaged but not moving up at all, then something has gone in the drive to them, usually a gear in the free arm area. In which case, take to the shop for repair.

attach the sliding foot by clipping off the current one, placing the sliding food onto the needle plate, lining up the clip with the attchment point and lowering the pressure foot down onto it so it clicks in.

Now, does your machine have a little lever device to the left and just behind the pressure foot, have a look for it. If yes, then pull it down, this is the buttonholing trigger and it connects with the sliding foot to trigger the reverse and stitching of the second side.

Program the machine for button holing, this might be pushing in a numbered code, on my 6500 there are five buttonholes and they each have a code that I enter.

Place your fabric test sample under the pressure foot and put the button into the back of the pressure foot, there is a little ratchet device that closes up holding the button firmly to get the right dimensions.

I always do at least 2 test buttonholes using same fabric, usually 2 layers with interfacing between.

Start the buttonholing sequence by pressing on your machines foot control, it should sew backwards away from you down the first side of the buttonhole, and the trigger should connect with a bit on the slide foot triggering the machine to stop, sew the bar tack, and then reverse and sew the otherside and final bar tack.

That's how it goes on my 6500, I hope this applies to your MC10000 too, it should be very similar. Your machine probably has at least 3 or 4 different types of buttonholes it can do. If you don't have a manual for it, it probably is worth sources one as these machines have lots of features to use.

This machine was not designed to sew THIN material. It is an upholstery machine and it will never sew thin fabric very well. You can try a smaller needle(size 16 or less) and shorter stitches. There is also an adjustment to raise and lower the walking foot located on the backside of the machine. It can be recognized by the wing nut holding it in place and that it slides up and down when it is loose.
