It had a couple of problems
1 - The motor belt was very loose.
I've made this fix several times; you have to make an extension to the idler pulley bracket because it doesn't have enough travel
2 - The motor made a horrible noise when running

Pfaff 332 (1950s)
My 2nd 332 for the purpose of "rescue and resale"
It had a couple of problems
1 - The motor belt was very loose.

2 - The motor made a horrible noise when running
So the guys on the FB Pfaff site gave me some ideas about the motor (none of them applied) but when I went in to look at it again I found that the two main screws holding the motor together from front to back were loose? Once tightened the motor was as good as new.

Necchi Logica 592 (1980s)
I sold my Sensor Sew with great regret but I was after the real deal... The Logica 592
The 592 I think is the primo version; it has both the speed control slider and the needle position switch. A couple of the things that the SensorSew does not have.
As soon as you go for a computerized machine you have to at the minimum have needle up-down position.
The Logica has needle up-down and motor speed control
It was a risky ebay purchase and of course it had a machine killing broken part in it.
It has several unfortunate damages but I will pick a parts machine when I find it.
Came with original manual all of the attachments and cover.
The broken bit is probably very common but is exactly the type of part I can fabricate.
This is the part that raises the feed dogs out of the Quilting or down position.
Reading online it seems that if you force the up-down lever when the cam is out of position you can break it.
The steel insert is there to slide on the plastic cam so I decided to make the whole thing out of steel
I digitized into cad but got a key dimension wrong so had to make a second one, I will go back to the cad model and correct it.
With a quick test it seems to be working perfectly
No more (eye roll) free quilting though
Update 04.20.18:
Love using this thing however, it does not have left/right/center settings for the needle! (least I haven't found it or a way to fake it) Necchi really dropped the ball on this one, I don't think the SensorSew does either maybe you have to work with the adjustable feet?
It does however have a better up/down needle position than either the Pfaff 1471 or the Bernina 1230 in that the needle goes up or down WHEN you hit the button instead of waiting for another cycle.
