Loading Reliability issues

[unborn bison]

Hi <@&1304550334839918672> I have a Jabberwocky tollhead and a new boxturtle I'm trying to get going.
I have run the calibration several times and things sucesfully load.
I'm having issues with intermittent times where random lanes will not load, it seems the toolhead sensor doesn't seem to be triggering reliably. Hoping someone can help me here, I'm pretty stuck.

@spice tundra ^

also @pastel sage for viz, I had started to post this in the jabberwocky chat, and realized it might be better suited here.

How is it failing?

If it is directly related to the sensor in toolhead, it may be best to continue with the JabberWocky team. We can help with what we can, but idk if any of us actually have experience with it

[unborn bison]

it goes to load, the filament makes it to the toolhead and the toolhead sensor doesnt seem to trigger.

[spice tundra]

yeah that sounds more like toolhead concern than an AFC one

[unborn bison]

its intermittent though

backing the lane out ~10 mm and back in triggers it. 😦

Check the wire harness for those sensors. The way they have it in there, it’s possible one of the solder joints is broken.
I had to fix this on my JW basically immediately after getting it going

[unborn bison]

I'll give this a look. I'm soo close. lol

I would also go over the tensions on your BT extruders carefully
If they’re making dust, it will work its way into your toolhead sensor and will cause that d2f switch to fail early

[unborn bison]

i'll check dust and tensions again too.

thank you all, hopefully I can get this guy up and going today. @lime juniper @rich fjord @spice tundra

ok, so i have an update. when the toolhead is in the pooping position when loading, the sensor does not trigger. once I move the toolhead either to the right or forward i hear the click and then I see the toolhead sensor triggered.

when the toolhead is in the middle or forward position of the bed the sensor triggers immediately on load

I'm guessing that I need to find a way to "on load" go to this coordinates

I'm assuming I need to use the park macro before load, just not quite sure where it insert it in. any suggestions?

[marble flower]

It sounds like you might just need something to hold the bowden tube straight up and down at the toolhead. I swear I've seen something that clips onto the tube and holds it, but can't find it now. But thats just a guess based on the fact that it works in certain positions.

[unborn bison]

Hmm that's a good idea, I have seen those, I'll give that a try.

[unborn bison]

I added the PTFE guide, and it did not help. 😢

[spice tundra]

Could try writing your own macro to do the pieces and moves you want instead of the default AFC order

[unborn bison]

any suggestions on where to do this?

[spice tundra]

I’d write in your normal macro location and call the existing macros and do your extra moves and then you can change the name of the brush macro called in afc.cfg I think it is

[unborn bison]

I see, I'm already doing ABP (A better poop)

I'll have to sit down and dig through the macros and see where I can add a move in.

[spice tundra]

You’ll probably have to add after cut macro otherwise I don’t think anything runs before load

[unborn bison]

I see. Hmm so move to XY before pooping?

[unborn bison]

I think I will experiment with the restore_position var and see if that helps
