If I knew what "hybrid" meant it could explain it...

As I understand it, Hybrid motors have a magnetised rotor as opposed to the soft iron cores used in earlier types.

If you are connecting it is parallel and only giving it 4.2A, you are under powering it.

That makes it very unlikely to be motor saturation :(

I wonder if it's a resonance (force/mass) issue - extra current = extra force. Might be worth trying a mass damper on the motor (i.e. I would stick a large/heavy washer to the motor pulley with a bit of double sided tape and re-test)

[edit] ISTR you have a spare pulley, try sticking that on top of the existing one (use DS tape or blu-tack something with a bit of 'give')

Today I reworked the tapered Gibb strip fixings.

The original adjusters are totally naff allowing the the Gibbs to move, so they went from tight to loose as you reversed direction on the slide :nope:

To fix it I fitted 35tpi x 3/8" studs, screwed the adjusters on to them, (still sloppy) then bolted on end caps to pinch it all together... TIGHT
