"The CSM1001 should work on all 206RB machines regardless of whether they were made in Japan or China. On some of the older models, the synchronizer will not go directly on the hand wheel. The customer will have to use an adapter that comes with the motor and threads in to the shaft of the machine." Consew

Needle stop down is good for turning corners, Needle stop up is better for inserting and removing materials under the foot and needle.

You can’t add a synchronizer to the CSM1000 to give it needle positioning. You have to select the CSM1001 model motor option which comes with the synchronizer and is programmed for needle positioning

SEWLINE SLS-2000 Sewing Machine Servo Motor Info and Demo.I recently installed a Sewline SLS-2000 Servo Motor with needle positioner on my Consew 226 and thought I'd post some info on this motor since I couldn't find much when I looked. I'm very happy with it and all its functions and power.

Perfect. Thank you so much, John. I’ve bought quite a few things from your company over the years and never been disappointed, especially with the customer service! That’s why I was so persistent. I really didn’t want to buy it anywhere else. I’ll order that tonight. It will be so nice to be rid of that clutch motor! Happy New Year, Libby
