Needle Positioning motor

I don't have any type of "slow start" feature on mine. But at the lowest speed setting, I can certainly go as slow as I want to.

Are you saying that with "slow start", you can start off slowly, and then "ramp up" to full blast without re-setting the speed control?

Yeah, that's pretty cool, huh?  Mine doesn't seem to have a dial that allows speed adjustment, it appears to be accomplished by adjusting the speed on the digital setting (I didn't ask about that!) but for my purposes I'm not sure it's that important since this is an overlock machine.  I'll have to spend some quality time with the manual.

On my servo I can adjust how long it takes to go from 0-100% when you step on the pedal.  I didn't like the delay at first, but after trying a bunch of settings, I found a setting that I like.  Just a little tiny bit of delay, makes it really easy to go one stitch at a time, in places where I'd walk the machine by hand before.  Between this and the needle positioning, I very rarely touch the hand wheel anymore.  I like it.
