For some reason sometimes it will unload beyond the load sensor, and ive recalibrated my lanes/bowden length not sure what to adjust to fix this from happening during swaps, it will sometimes work and sometimes it will throw the error
#[Solved] lane1 Current lane not loaded, LOAD TRIGGER NOT TRIGGERED

When you calibrated Bowden length did you hold the buffer closed?

When you calibrated Bowden length did you hold the buffer closed?
No i was told not to before because i have toolhead cutter
steel venture
I would recommend trying that, cutter doesn’t impact that

Also your tool_stn_unload could be too much, if you still have problems you can add and make afc_unload_bowden_length a little bit shorter than your afc_bowden_length. If you update afc_unload_bowden_length make sure it does not already exist in the Afc_auto_vars.cfg file

i dont remember where i got these number i feel like i remember grabbing them from a table that showed starting values for certain toolhead combos but i cant find the page

Also your tool_stn_unload could be too much, if you still have problems you can ...
when trying to calibrate the tool_stn_unload my toolhead sensor is above the extruder gears and it says to manually retract until the toolhead sensor is off when i do that i start at the recommend 70 for the goliath and then i also have to manually retract 10 more times at 1mm to get the toolhead sensor to go off, should the value for my tool_stn_unload be 80 now?

Yes 80 sounds good to try, so this could be why it's retracting to far if AFC has to do two tool_stn_unload lengths to untrigger your toolhead sensor

Seems to be better after doing all of the above, seem to be having a different issue after getting that figured out, i still use kamp purge line witch idk if that is smart but seems to have under extrusion when it goes from kamp purge line to the start of the print

Is there a tool change between purge and printing?
rich crescent
no, seems to be struggling to extrude right at the end of travel moves from purge/poop and toolchanges
steel venture
You might check if kamp purge has a retract at the end of it
rich crescent

it does
steel venture
Well there isn’t one at the beginning of your print gcode I would guess
rich crescent
so i figured out retraction, but now im mid way through another print with the load lane error, it unloaded on filament swap beyond the load sensor again
is their more info you guys need from me to understand whats going on?
i shouldve also specified im using a nightowl not a BT
knotty goblet
What's in your AFC_auto_vars.cfg file?
knotty goblet
i shouldve also specified im using a nightowl not a BT
Well they basically work the same, just night owl does not have the espoolers

This file is autogenerated and updated when variables are not in your normal AFC config files
[AFC_hub NightOwl_Hub]
afc_unload_bowden_length: 1300.0
afc_unload_bowden_length:1280.0
i havent saved and restarted to apply the unload bowden length
steel venture
Why are there 2 unload lengths there? Also what’s your load length?
steel venture
Ah, you can comment it out now without hurting anything
knotty goblet
You can update the unload length without restarting with SET_BOWDEN_LENGTH macro but remove the top one first and just save before running it

Also length can be an equal like UNLOAD_LENGTH=1280
rich crescent
okay ill see how that does now
previously it was 1350 with TN not held down during calibration and now with it held down and lowered its 1280
knotty goblet
When you find a number that works you need to manually update that file, I forgot we don't have a save macro for it 😑
rich crescent
i dont see a bowden length i only see the bowden unload length
knotty goblet
Bowden length is in your AFC_Turtle_1.cfg file
rich crescent
[AFC_hub NightOwl_Hub]
afc_bowden_length: 1300.0
move_dis: 50 # Distance to move the filament within the hub in mm.
cut: False # Hub has Cutter
aw yep does this look right?
besides the new number il input
knotty goblet
Yup
rich crescent
thank you very much for your help again much appreciated i will come back to here if more issues arise on the next print
also is their a way to search through like old threads to find people with the same issue so i can look through the thread and see what their solution was?
steel venture
The normal search should work
rich crescent
No errors yet
knotty goblet
@rich crescent is this now solved?
rich crescent
I believe so
