Topic: Filawinder Construction Troubleshooting

Hi all,
So I assembled a filawinder kit. I plugged everything in and it is not working. If the motor is plugged in and the servo is unplugged, the motor rotates 'normall' (or at a decent pace).
If I have everything plugged in both the motor and the servo will move forward in short bursts, approximatly 1 per second. See video: https://drive.google.com/file/d/0B7YEx5 … sp=sharing (ignore the sound)

As far as I can tell everything is plugged in correctly, and I used a multimeter continuity tester to verify all the buttons were working and that the signal is going to the input of the arduino.
I have also been unable to get the laser to do anything.  I have been unable to get any behavior other than the two described above, regardless of the combination of buttons and switches pressed.

What should I try doing to get it working?

Thanks!

It looks like there is a short somewhere, and the Arduino is rebooting.  Try unplugging the ribbon cable.  Since the laser isn't turning on, it might be related to the cable or the sensor.

So I had tested it without the ribbon cable and it changes nothing.
If I unplug the servo the motor turns continously, and the behavior does not change when I plug in the laser, which doesn't turn on. With all combinations of button presses and switch flips.

Re: Filawinder Construction Troubleshooting

I found the solution to this in a much earlier post: the power supply.
After working for the longest while, the supply that came with my Filawinder decided it couldn't hold its rating anymore.
Swapping it out for a 12v 1.5A supply I had gave the Filawinder the power to run the servo correctly, without dropping the current on the control board itself.

Filastruder 2607 w/ Filawinder @1.75mm.
Dual-extruder MaxMicron Prusa Mendel: RAMPS 1.4 w/ Repetier Firmware+Full Graphic LCD Controller, stock hotends, 3Dator extruders w/ MK8 gears, insulated enclosure w/ 2 heat lamps, RPi 2B w/ Repetier Server.
0.1-0.2mm layer height, heated bed w/ PEI surface, inductive-sensor autolevel, 0.5mm to 0.2mm nozzle diameters.

This power supply is brand new, though. Also, shouldn't the laser work if the servo is unplugged?

This is a video of the motor on with the servo unplugged, and everything else on. You can hear me pressing random buttons and switches which had no effect.

This is a video of when the servo is plugged in. Showing the buttons do nothing.

Is with the servo unplugged. I then plug in the laser and on difference happens.

As explained in the post where I found the solution myself, some of the power supplies simply don't meet their ratings, even when new (lowest bidder Asian manufacturing).
The laser board can't power up correctly with the short bursts of power at the main board.
Try a different 12v 1.5-2.0 amp supply if you have one on hand, and see if anything changes.

Re: Filawinder Construction Troubleshooting

Hi, we do not have any other 12V power supplies though we are working on getting one (and as soon as I find an old computer power supply it will be used) - do you have any other recommendations until then?

Update: I managed to connect a computer power supply I took out of a computer and connected the wires and the filawinder started working. How would I be able to get a replacement power supply for the filawinder?
Thanks!
