Topic: filawinder guide not moving.

I just got my filawinder and filastruder up and running with great results and only a few snags. The filament guide on the filawinder is not automatically moving. I set the left end stop than the right, than I start extruding. After one rotation (when the magnet moves past the hall sensor) the guide moves to the left guide stop (min). when the extruding continues the guide will not move again, it just stays in the same stop unless I manually move it by changing the Min end stop. All hardware seems to be working fine so I can only assume the problem is me. What am I doing wrong? Thanks in advance!

Re: filawinder guide not moving.

Did you follow the Filawinder instructions exactly when setting it up? One issue is if you set the start position of the Filawinder after you set the endstops. If you didn't, then it might not work right. You have to use the left and right buttons to set the endstops and then use the center button to set the start position, ensuring that the last direction you moved is towards the middle of the spool.

Also double check that the buttons are plugged into the correct headers.  If you have left and right switched around, the winder will be confused by having the left limit set further right than the right limit.  Since you can move the servo and it responds to the magnet, that is most likely what the problem is.

Thank you, that was it. Everything works perfectly now. Happy printing!

Re: filawinder guide not moving.

Hi,

So I haved used my winder a few times worked great now I have ran into a problem. I sent the min and max on the guide and then set the middle button. Some times it moves a few times and stops other times the guide does not work at all. I tried moving the min and max wires on the headers and that did nothing. PLEASE HELP!!!

Thanks, Nick

Re: filawinder guide not moving.

im haveing the same problem, was working great then just stopped, doing everything as before, the connections are in the right place, and still all connected, the servo moves in the right direction when i press the left or right buttons and turn the dial, the middle button also sets the left starting point yet when i turn it on and the motor spins the servo fails to move. re uploaded the firmware, still nothing.

ok fixed it, the hall sensor hadn't moved since assembly and still flat against the PCB, when i pulled it out closer to the magnet the servo started sweeping again and returned to normal, i do not know why it was ok
then was not when it did not move.

hope this helps someone.

Re: filawinder guide not moving.

If the hall sensor stops working again, take a close look at its legs.  It's possible that one has begun to crack from the bending.  Or it might have been right at the edge of being able to read the magnet, and simply moving it close did the job.

Re: filawinder guide not moving.

Another thing I noticed on mine is the servo is not particularly accurate and may not update it's position for many turns and then suddenly jump a large amount to catch up.  Researching on the web, I discovered this is very typical of most cheap servos and the fix was to replace with something a bit higher quality (~$30 range).  The folks doing robotics with servos have to spend even more ($50-$100) to get accurate, repeatable movement.
