I see now why you're asking if a needle positioner is required in order for that button to function..

What about the other menu functionality? Are you able to set forward/reverse and min/max speed?

Yes I managed to change the other two you've mentioned. 

Still no reply from the seller, and I can't see any sign of him/her being on vacation. I'll wait another day or so. Supposed to be a very reputable seller.

After reading this thread I thought I'd have another go. Another waste of time. Tried every setting with the same results. Everything else works fine except the needle position. No matter what the setting, every time I stop the needle is in a different position,sometimes up - sometimes down and never up/down in the same place either. It goes slow enough that it's more of an irritation than a pain but short of ripping out the speed reducer and replacing the handwheel and motor pulleys, I'll live with it.

What settings did you try for P-15 (Needle Detection Mode)?
