I know the old style foot controllers get warm. But .... I just finished sewing about 4 feet worth of decorative stitches on our MW 7 Jewell with the new cams. Been having some trouble with it eating needles. It can be finicky so I was going slow.
After finishing I showed it to my wife and then we walked back to the sewing machine and I bumped the foot controller with the side of my foot. I sew either bare foot or in socks. I just don't have a good "feel" for the controller with my shoes on.
THAT THING WAS VERY HOT! Too hot to pick up. I picked it up by the pedal part and got if off the carpet.
The thing is, it's a new foot controller. We bought it especially for this machine since when we got it it had no cord block or controller.
So my question is; is it normal for these things to get hot enough to burn you when you sew a long continuous stitch slowly?
