Pfaff 145 H3 outer pressure foot does not raise

[ThomasBH]

Hello,

My Pfaff 145 was working fine for  months, then all of a sudden after changing out feet the outer foot will not raise. Only the hand/knee lift will raise it now. If I look real close it moves about a mm when the inner presser foot is at BDC (bottom dead center)

I've puzzled through all of the adjustment guides on the 1245 as well as google searches and can't find anything.

Any suggestions?

 

Thanks

Try reinstalling the stock feet. Does that fix it? If so, the replacement/aftermarket feet may be the wrong height.

Thanks for the suggestion, but no, even with no feet attached watching the machine cycle the outer bar barely moves up and down at all, just a mm or two.

Solved!

I guess that a "partially" compatible foot (cheap Aliexpress crap) must've knocked the other foot out of timing so the foot wasn't arriving at the exact time as the needle reached the bed, and only when it reaches at the same time does the 2nd foot actually raise and lower when the inner foot is at the bottom. It has an interesting mechanism for sure!
