FilaWinder Documentation (Page 15 of 16)

You dont seem to understand the problem.

Filawinder board sends around 6V to the motor in automatic mode at slow speed. It almost never turns at maximum speed in automatic mode because filament is not extruding fast enough.

Relay is 5V for a reason. Reason is that filawinder motor sometimes only gets around 6V-7V
Powering buck converter with 7V which also powers relay down the line makes relay not activate sometimes.
Buck converter is used to protect relay from anything higher then 5V . But it cannot protect from under voltage.

I need to know if any PINs can be reconfigured to state  ON or OFF when motor is engaged.
I do not want to change how motor behaves, i just want to use unused pins if i can.

I know for a fact that any pin can be programmed to do what ever, i just don know how to.
I dont know how to make pins to go HOT at 12V at same time as motor is engaged.

Where can i find pinout diagram ?

Maybe someone can help me rewrite the code for SERVO ?
Instead of sending angle information, just do ON OFF state for pins ?

he doesnt respond.
DO you know how to disable motor smoothing in firmware for automatic mode ?
Firmware downloaded from link on first page of this topic does not compile.
Without changing anything it says "exit status 1
EEPROMex.h: No such file or directory so i downloaded the EEPROMex library.
But now i have Error compiling for board Arduino Nano.

Hi,

Please support for my filawinder

Info for mother board
See pictures

Left

Motor is ok
Auto ?
Guide min ?
Sensor cal ?
Servo ok
Guide max ?

Right

Knob ok
Power ?

For command i am identify by number ok ? 1 to 5

Please help mee for connect corectly command to my mother board

Bests regards

Hello. I am having a hard time sourcing the components for filawinder PCB here in Brazil, so I wonder if it is possible to replace same of them for off-the-shelf arduino gear. I.e.

- The PDV-P8103 photocell, can I use the standard arduino 5mm LDR?

- Line Laser Module, can I use the standard 650nm 5V 5mW red laser emitter or 5v laser diode arduino uses?

- Hall Effect Sensor OH090U, can I use more common US1881 instead?

- The 4 resistor 5 pin resistor network 4605X-101-103LF doesn't sell here in Brazil nowhere that I can find. Can I simulate one using four 10k resistors like the image bellow?

- Can I use a 37mm motor with more than 15 RPMs?

Thank you for creating and supporting filawinder.

Hi Tin, thanks for answering.

Yeah, I am doing the PCB from there, because I could not download the one fredaxe published here in 2014 (the files are not online anymore).

My actual problem is finding some of the components here in Brazil.

Hello Ian, thanks for the really good work on creating and supporting filawinder!

How about putting two magnets with opposite poles next to each other in the spool holder (problably with little redesign of the STL to make them fit) so they will arm and disarm (latch) the US1881, it would be a good solution?

Thank you. One last question, I have a bunch of unused STP55NF06L MOSFETs here (replaced from RAMPS boards). Can I use them instead of IRLB8721? Or perhaps IRF1404, which is easier to find here?

#1 check the magnet is close enough to the hall sensor.
#2 check the hall sensor following my video tutorial https://www.youtube.com/watch?v=lWezV1Ooa4I

Guide moves when magnet passes by the sensor.
I am not sure if motor has to spin or not at this point.

Oh i see. photosensor does not register correctly.
Did you calibrate ?
use piece of filament to calibrate, not a screw driver or anything else.
Clear filament can cause issues but not likely.
Make sure filament is passing at the correct distance from the sensors casting good shadow from the laser.
Laser does work, right ?
And it does point a straight line directly at the sensors right ?
and filament is in between them casting the shadow on the sensors ?
Check the wiring.
I had wiring issues. Pins are cheap, they corrode overtime so spray some alcohol on them, work them in an out couple of times (power disconnected obviously) dry and try again.

Sorry, have to go with the "did you plug it in" method sometimes lol

yeah.
I had that too. For what ever reason firmware gets corrupted so i had to reflash it my self at least 2 times in the past.

Hi all im trying to make my own filawinder from scrach and cant seem to get the firmware on to an arduino nano but i keep geting an error....
Error compilling for board arduino  nano... any suggestions  on how to fix it

And yes its all plugged in  properly
