It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

in these days i made many test with tensioner....
i left closed loop tensioner idea because i have not time anymore to develop...
i left solenoid tensioner too and i changed it with a small stepper (taken in a broken printer)
powering only one phase of a stepper motor (with same pwm out i used with solenoid) it doesn't run and i can control its holding torque.... then i made a new pulley for it.... and when winding i make 3 or 4 turn around this pulley....
it's a simple method and i ike it....
i will take some video and photo in the next days....

Maybe I'll do that when I start on mine. Then I'll post them here.It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

David, no, I haven't done anything at all on the winder since you sent me the lead screw. I got too busy. But now I want to get the PICs and get going on the thing.It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein

a short video.... random tpl between 42 and 31.... you can hear traverse speed noise changing at every layer.... and values displayed on lcd.....

Then I tried inlet and outlet wire guides to the motor roller with several turns around the rubber tired wheel and that didn't work either. Both of these tests were with nothing connected to the motor. I was using 42 gauge wire.
How many turns around the pulley are you using? Is the pulley simply concave or is there a spiral groove in there to guide the wire? and what gauge wire are you using? It looks heavier than 42 but pictures can be deceiving.
Thanks

wire in picture is 42... there are 4 or 5 turns around the stepper pulley (it is simply concave....not spiral groove...)
....the trick is to have a little of tension already before the tensioner pulley..... i made that with the little screw with hole that you can see near the pulley: the wire turns around it, goes through the hole.... and then around the tensioner pulley...

Elepro,
I would worry a little about the wire and insulation becoming fatigued when going around those sharp bends at the eyebolts. I had a problem with that were half my coils had internal shorts after going through the extreme slalom tensioner I tried out a while ago. Just something to keep an eye on.

I wouldn't use the eye bolts at all... not metal ones anyway. I had issues with shorts onto polished steel blades, so I think the wire rubbing on metal is not a good idea.It would be possible to describe everything scientifically, but it would make no sense; it would be without meaning, as if you described a Beethoven symphony as a variation of wave pressure. — Albert Einstein
