Unable to unload the tool anymore

[thin thicket]

but regardles if I keep it turned ON the command still crashes the system

[mortal lava]

Did you get this sorted?

[thin thicket]

No

When I issue command TOOL_UNLOAD LANE=lane3 klipper crashes completely

My Hub sensor started acting up, like being OFF while filament is in, when I move bowden up by hand behind the hub i hear it click and then start showing up

but regardles what I do, when i choose Tool unload it crashes everything

Just updated to latest SW via mainsaill - made no change

[mortal lava]

Im seeing an error in relation to the hub in your log. What does afc status show

[thin thicket]

21:09:01
Turtle_1 Status
LANE | Prep | Load |
lane1 | <--> | <--> |
lane2 | <--> | <--> |
lane3 | <--> | <--> |
lane4 | <--> | <--> |
HUB: x Tool: <->

[thin thicket]

I can hold the bowden manually up, so the hub sensor would detect, but that makes no difference

[mortal lava]

Its likely still too flaky for the software.

[thin thicket]

Fold example when I hold bowden up:
21:10:34
Turtle_1 Status
LANE | Prep | Load |
lane1 | <--> | <--> |
lane2 | <--> | <--> |
lane3 | <--> | <--> |
lane4 | <--> | <--> |
HUB: <-> Tool: <->

[thin thicket]

It doesn't even start doing anything, like instant crash....

Hub requires 5.5mm ball inside? i have 5mm

[mortal lava]

If youre still on the ball hub its likely just worn out.

Ive already had to replace the one in bbt-16

The D2HW hub is way more reliable

Also lets look at the output of [yourprinterip]/printer/afc/status

AFC thinks the tool is unloaded

Wait no that's so hard to read pasted into discord lol

Hmm that's actually all looks pretty normal

[thin thicket]

found a workaround by heating the nozzle and then manually retracting until it comes out from lane

will take everything out, print new hub and see if that changes anything

[mortal lava]

I would definitely recommend upgrading to the new hub before doing any more troubleshooting

[thin thicket]

Yep, that's the plan

what about extruders? are they Ok to leave with balls?

[mortal lava]

Im still using the balls everywhere but the hub in bbt-16

Extruder ones will wear out eventually too but the hub gets "cycled" more than the extruder ones.

[thin thicket]

ok, will try... thanks! @mortal lava

[thin thicket]

I have reassembled my hub, it works ok now, but Tool unload again instant crashes my klipper... Any ideas where to start?

I am sure that hub is working ok, so as other sensors

Klippy log please

[thin thicket]

Ok, here it is

This space needs to be fixed in your AFC.cfg file
