Toolhead won't retract at end of print and then hub isn't empty.(SOLVED) | ArmoredTurtle 3D | Page 1

shrewd agate Apr 26, 2025, 11:02 PM

#

It just started 2 days ago never had this issue. It cuts and everything. Then I have to cancel the print and clear it manually. Only at the end of the print though so no lost prints. I've checked my settings and nothing has changed except I upgraded everything right before it started.

#

I thought it was just not retracting enough but I changed it and it didn't fix it

What's the current state of your hub? Have you checked your filament to verify that there are no warn in divots in the filament?

hushed basin Apr 26, 2025, 11:48 PM

#

You are able to do regular changes without an issue?

shrewd agate Apr 26, 2025, 11:56 PM

#

Yeah

#

It's still in the head

#

I'm slowly hoping my Unload.. at 80mm now so... I'll see what happens

fierce thunder Apr 27, 2025, 12:08 AM

#

May wanna verify that your toolhead sensor is working properly as well

#

those ball bearings do wear

shrewd agate Apr 27, 2025, 12:42 AM

#

Works great without afc

#

I'm trying unload to distance

#

Of it stays doing it I'll tear my head apart

river inlet Apr 27, 2025, 12:48 AM

#

what commands are you trying to do?

shrewd agate Apr 27, 2025, 1:50 AM

#

I'm just testing load unload right now

#

Then will see what happens in the next print just to see if I'm stupid and it happens all the time

shrewd agate Apr 27, 2025, 7:36 PM

#

It seems to be working.... including the runout sensor

#

Nope just did 2mm of the wrong filament(All I had not the issue) but did the cut and then just didn't retract or disengage the toolhead. Bt started squealing so I unlatched the extruder and now it's limping back to the box turtle. Had to leave for my wife's bday party before I couldn't see if it still thrown an error.

#

Ignore the green 🙂

#

Red was in the 4th lane but I was short that much. A son as I unlatched the toolhead extruder it started to unload

#

It loads and unloads manually perfectly. It only does this at the end of a print.

river inlet Apr 27, 2025, 8:03 PM

#

sounds similar to an issue we are seeing with someone else that their toolhead sensor wasn't registering all the time, if you can insert the filament and get it to not register in the GUI then its NG and needs work in some manner

fierce thunder Apr 28, 2025, 12:13 AM

#

What's the status of your toolhead sensor and where is your filament?

shrewd agate Apr 28, 2025, 12:14 AM

#

#

It's clear

#

I just had to manually finish the move past the hub

#

It's all so to the extruder not retracting or disengaging

#

It's perfectuntil the end of the print. Even does changes

river inlet Apr 28, 2025, 12:18 AM

#

shrewd agate It's perfectuntil the end of the print. Even does changes

What command is in your print_end?

fierce thunder Apr 28, 2025, 12:21 AM

#

There are no BT macros in his print end, just looked at his klippy file

shrewd agate Apr 28, 2025, 12:29 AM

#

The unload one that's been there since the first print with bt

#

It stopped spring right a few days ago

#

It's the one from the sample

river inlet Apr 28, 2025, 1:35 AM

#

I have no idea what sample you are referring to as there is no Print_end in Boxturtle or AFC documentation.

#

Also there is nothing in your print_end to tell it to unload

Sorry to sidetrack but what screen are you using?

#

hushed basin Sorry to sidetrack but what screen are you using?

This isn't a klipperscreen debug thread 🤣 jk

hushed basin Apr 28, 2025, 1:42 AM

#

No but it’s relevant enough to him 🫣🤫

fierce thunder Apr 28, 2025, 1:43 AM

#

But I see why you are asking

shrewd agate Apr 28, 2025, 2:14 AM

#

It's on my slicer profile

river inlet Apr 28, 2025, 2:16 AM

#

ok care to share it?

shrewd agate Apr 28, 2025, 3:35 AM

#

Bt_tool_unload
Print_end

#

All caps

#

I've never had to change it and it's always worked. Until maybe Friday

#

I upgraded Friday

shrewd agate Apr 28, 2025, 3:56 AM

#

Yeah I'm not sure why my screen looks like this. After the update the bottom of the screen is cut off... so not sure

fierce thunder Apr 28, 2025, 4:03 AM

#

shrewd agate Bt_tool_unload Print_end

Add this before your BT unload G92 E0

#

There is an issue that we are currently looking into that's probably causing your issue. But until it's fixed adding zeroing out the extruder should allow the unload to be successful

shrewd agate Apr 28, 2025, 12:47 PM

#

added. will let yall know

hushed basin Apr 28, 2025, 12:48 PM

#

shrewd agate Yeah I'm not sure why my screen looks like this. After the update the bottom of...

Let me know what screen you are using 👍🏼

shrewd agate Apr 28, 2025, 1:30 PM

#

Ldo kit. So

#

Let me look it up

#

Big tree tech

#

4.3

hushed basin Apr 28, 2025, 1:56 PM

#

Thanks

rose totem Apr 28, 2025, 4:05 PM

#

pitft 4.3 2.0 or 2.1

#

I have both @hushed basin if you need help troubleshooting

#

(although i need to get my v2 actually back up on modern afc first hehe )

hushed basin Apr 28, 2025, 8:00 PM

#

shrewd agate Let me look it up

sorry to further side track this thread but are you up to date with klipperscreen?

shrewd agate Apr 28, 2025, 8:02 PM

#

I believe so...i did update all

shrewd agate Apr 28, 2025, 8:03 PM

#

rose totem I have both <@1102943046275960852> if you need help troubleshooting

In truth i don't know off the top of my head. I'm at work but I'll look when I get home

hushed basin Apr 28, 2025, 8:03 PM

#

ok thanks

shrewd agate Apr 29, 2025, 1:57 AM

#

Didn't help

#

Still stuck in hub cause didn't release

fierce thunder Apr 29, 2025, 2:30 AM

#

Ok what didn't help, and you get any errors in the console?

shrewd agate Apr 29, 2025, 2:44 AM

#

It didn't release the filament until I unlatched my toolhead

fierce thunder Apr 29, 2025, 4:59 AM

#

Have you double checked your ball bearing to make sure you are using the right size or that it has not worn down. @somber yarrow was having the same problem that you are describing and it ended up being a problem with his toolhead sensor.

somber yarrow Apr 29, 2025, 10:39 AM

#

Ya I beat myself up for 2 days to figure out that ldo sent 2 sized bearings... double check see if your bearing is right size for sure...

shrewd agate Apr 29, 2025, 2:24 PM

#

It was working great. Until I updated

#

And it will change with no problem is only at the end of the print that it messed up

#

When I get home I'll be checking my tool unload stuff.

#

And i think it's a 2.1

fierce thunder Apr 29, 2025, 3:05 PM

#

So really when the error happens, immediately uploading your current klippy.log and AFC.log file might really help us out in figuring what's going on.

river inlet Apr 29, 2025, 3:34 PM

#

I would also move that BT_tool_unload inside your print end so that it shows up in Klipper logs. Also lets you make changes easier

shrewd agate Apr 30, 2025, 12:08 AM

#

I can't cause of the macros I'm using. And the the one I uploaded is when it happened. It doesn't show up anything

#

I can't edit the end macro easily

#

I've tried

river inlet Apr 30, 2025, 12:48 AM

#

what printer is it?

shrewd agate Apr 30, 2025, 1:10 AM

#

Voron

shrewd agate Apr 30, 2025, 1:26 AM

#

2.4 350

river inlet Apr 30, 2025, 1:29 AM

#

I don't understand how you can't edit the print_end then

shrewd agate Apr 30, 2025, 1:44 AM

#

The guy who made the macros I used have then read only... and when I try to add they just get ignored for the print end. I can change print start

shrewd agate Apr 30, 2025, 1:59 AM

#

It cuts the hotend off before it can unload if i put it in

#

Tell me what to put and I'll try and add it again

shrewd agate Apr 30, 2025, 2:27 AM

#

I know how to write the macros i just can't get them to override just the print end one

river inlet Apr 30, 2025, 10:10 AM

#

I would copy the contents of the file and make a whole new file then

shrewd agate Apr 30, 2025, 11:44 AM

#

It's fixed. I kept adding 1mm to the tool stn

#

No clue how it got messed up

#

And why it only was affected at the end of a print

#

But it worked

#

Toolhead won't retract at end of print and then hub isn't empty.(SOLVED)

shrewd agate Apr 30, 2025, 12:06 PM

#

Some how my stn was at lower by 7mm

#

So 52 instead of 59

fierce thunder Apr 30, 2025, 12:08 PM

#

Still does not make sense why that would cause the error you were seeing 🤷‍♂️

shrewd agate Apr 30, 2025, 1:48 PM

#

It wasn't releasing the filament from the toolhead causing the hub to be occupied. Pausing the print until fixed. At the very end

#

It's running great as of this morning. I added what yall said to add before the unload and I've upped my tool unload distance and the stn

#

I really need to get away from the macros I'm using and write some i can edit. When i find those I didn't know they were locked

#

They've been really good and work well but not being about to really change them have been a pain

#

Like I want to change the idle off time but... it can't be overridden

#

But thanks to everyone who was here for me 🙂 I do appreciate it

fierce thunder Apr 30, 2025, 2:09 PM

#

You can change the permission on the macros file so you can edit them....
