Power Fluctuations with Winder (Page 1 of 2)

I'll check those things and get back to you.  I'm not really sure what those parts are but I think there is a diagram I can reference.  I have to replace the power supply.  I have a 12v 1.5a one on there if I remember the specs.  It doesn't have an LED on it.

The motor did turn very slowly a few times but has stopped doing that.

I made sure the tabs were touching but that really didn't help much.  It is turning very slowly not in manual mode.  I can't get it to adjust the speed with the dial.  I played around with the wires to see if something was loose and seemed to get some reaction of the the servo wires.  When I get a chance I'll kook closer at those to see if something came loose.  Any other ideas would be appreciated.

I rewired the knob.  I'm now getting consistent results but still not correct results.  If I put it in auto mode and put the servo all the way to the max and switch it to Manual, the motor turns and the arm swings to the left in small increments.  I don't have the gear cone on there so the magnet isn't going by the hall sensor.   So in about 30 seconds, the arm is all the way to the min.  I can't find a short anywhere.  That's not to say there isn't one but I can't find it.  Do I need to rewire the whole thing?

PM me your address, and I'll send you a new board.

I've rewired the knob once.  Do I need to redo the rest of the wiring?

When I turn the power switch on in Auto mode, I can move the arm around without problems.  When I switch to manual, that's when it starts messing up.  The motor turns slowly, doesn't respond to the knob.  I can't seem to calibrate the sensors.  Switching back to Auto doesn't change anything.  The motor keeps spinning but it doesn't respond to the sensors.

I've been having trouble with the brand of arduino clone that is in your kit, and ordered some different ones that I know are more reliable.  I'll send you one when they come in.  That sort of inconsistent behavior is most likely some problem with the microprocessor.

Did I send both a PCB and arduino the first time? If the electronics are completely replaced, then it would seem to be something with the buttons or knob.  Try swapping the switches so the power switch changes modes and see if there is a difference.  You can also plug the motor in to the last two open headers at the bottom left of the board.  That is an always on 12v connection so the motor should spin at full speed when plugged in there if it is working right.   

Try unplugging the sensor.  There might be a short there which is interfering with everything else.  The sensor is simple enough that I have only had 1 bad one out of hundreds, but yours might be #2.

If I sent you a second ribbon cable, try switching that out as well.

Perhaps the power supply isn't supplying consistent power?

One more thing to try is backing off the screws that hold the motor just a bit.  It is possible for them to get tightened enough that they bend the face of the motor inward just enough to interfere with the gears.

bbriggsgeek,
try taking the gear sprocket off the motor in case it is messing with the motor?  Though it does sound like the motor has issues internally.

I remembered I have an old 12v motor so I hooked it up to the MOTOR connections and it spun.  I was able to change the speed with the knob.  It's not the right kind for the winder but it worked for a test.
