<@&1304550334839918672>: I've problem with the spoolers on my Box turtle. Alle spooler have the same problem:
The gear on the shaft is tight, and the wheels are also securely screwed on. It seems as if the motors aren't generating any power. I completely disabled PWM, and it seems to have improved somewhat.
No Power on spoolers - specially on rewind

kit?

Do they spin freely by hand? No tight spots or drag or binding?

Yes they do - perfect, everything is smooth.

kit?
What did you mean with kit? I do everything by my selve only electronic and frame was bought, if you mean this 😉
vapid idol
Could you please provide video example of the spoolers moving?
vapid idol
That’s seems slow, how about a video turning by hand
Also, are you actually retracting filament? That scream is stepper stall, and the respoolers wont do anything if filament isn’t moving

I only test it with this command LANE_MOVE LANE=lane2 DISTANCE=-500. There was filament in the extruder. How can I test it else?
vapid idol
That is fine. A -500 move should move filament. Do you get that scream on all lanes?
wintry hornet
Yes, the scream is on all lanes more or less
vapid idol
Solve that first. Reduce speed in AFC.cfg
heady salmon
Are you sure the extruders are spinning the correct direction?
vapid idol
That as well
wintry hornet
Are you sure the extruders are spinning the correct direction?
yes, everything works with printing. The only thing is respooling on tool change
wintry hornet
Solve that first. Reduce speed in AFC.cfg
which speed to you mean
wintry hornet
You get that scream on tool change?
yes, correct
vapid idol
Then there’s no way that anything is working as expected
wintry hornet
Then there’s no way that anything is working _as expected_
Sure, the filament is cutted correct, the change working from on tool to the other, only, like I wrote, the rewind doesn't work
But now I correct the speed
perhaps the run_current for the extruder is a bit to high. I worked with 0.85

In this video your stepper for this lane's extruder is absolutely stalled. This is why the n20 doesnt rewind. Its not capable of pulling the filament back. That is not what it's there for.

But how can I test this sequence. With a single unload in the AFC plugin? I'll try so
wintry hornet
Lane move -500 tells both to move
Perhaps here some errors in the config? I haven't this sound when I unload the filament. I'll do also a video for this so you will see what happen in this case

No need to add since it's already defaulted to true and won't help with the long retracts
Also would remove pwm_value as this affects print assist and will more than likely cause you issues down the road. This value also does not affect the problem you are running into
wintry hornet
Do you have any ideas what I can test?
glass geyser
are any of your tools loaded to the toolhead?

Lanes
Alle lanes loaded. I've really only the problem with the rewind process. Loading work. All extruders work forwards and backwards only the spoolers work not backwards

Let's be clear about one thing: the spoolers are only responsible for rewinding the spool itself, not for actually moving the filament. It sounds to me like you might actually have a problem with the filament unload sequence/settings instead of an issue with the spoolers. If the spoolers themselves were an issue, you would end up with a lot of unwound filament at the end of an unload.
and this is why I should look at the latest video and not just comment after watching an earlier one. 🤦♂️
wintry hornet
Yes, the problem is the unwound filament. The unload sequence work fine. Perhaps someone have the config who works. Do i can compare the settings. I know dome things like bowden length a different but the rest should be the same. I use the afc lite board and everything like the BOM list
glass geyser
the stock config works for the vast majority.
Try removing the spooler from the tray and see if it spins better
wintry hornet
Good morning! I just checked out the plug of the motor with a multimeter and recognized that there are only 1.2 V when spool should work. Has anyone an idea what the problem is?
wintry hornet
I solved it. I made a new installation and flash also the board new. Now it seams like it work.
Thank you for all the help and ideas.
