<@&1304550334839918672>
Infimech TX printer (MKS SKIPR v1, no canbus) and Formbot BT kit.
Have been attempting to flash the AFC-Lite without success.
I have used several different guides to flash including these:
https://github.com/xbst/AFC-Lite/blob/master/Docs/AFC-Lite_Manual.pdf
https://usb.esoterical.online/initial_stm32.html
https://canbus.esoterical.online/mainboard_flashing#installing-katapult
https://canbus.esoterical.online/toolhead_flashing/common_hardware/AFC-Lite/README.html
However, the one step that always fails is the actual write when in DFU mode.
The AFC is confirmed in DFU mode and I do get the "File downloaded successfully" message each time.
When running ls /dev/serial/by-id/*, only the .../usb-Klipper... device is displayed, not the expected .../usb-Katapult... UUID.
The 24v line is connected and both the 5v and 3.3v blue lights are solid on the AFC-Lite.

Any help would be greatly appreciated and possibly prevent me from curb stomping this hardware into Oblivion!

If you double tap reset button

Does it go back to katapult mode?

#

Katapult is just the boot loader so if it already had it + Klipper it’s going to still boot up klipper

autumn pebble Jun 20, 2025, 1:22 PM

#

double tapping reset does not appear to do anything
what is the expected result?

shrewd flower Jun 20, 2025, 1:24 PM

#

If you selected the option when compiling katapult i would expect it to reboot
Into the boot loader

autumn pebble Jun 20, 2025, 1:24 PM

#

The option was selected

shrewd flower Jun 20, 2025, 1:25 PM

#

Details of the process - make menuconfig screenshots of both klipper and katapult as well as full terminal sessions of the flash, may help

autumn pebble Jun 20, 2025, 1:26 PM

#

Beginning screenshot-a-palooza now

#

BTW, which flashing guide should I actually use?
There are a few differences in each one of them.

shrewd flower Jun 20, 2025, 1:36 PM

#

i prefer the esoterical ones

plucky gull Jun 20, 2025, 1:37 PM

#

Just be careful to not go into the the CAN section on esoterical's

autumn pebble Jun 20, 2025, 1:41 PM

#

pretty sure I did try all of them

#

even the ones I was not supposed to 😦

silk meadow Jun 20, 2025, 1:44 PM

#

Use Isiks guide, flash without Katapult

autumn pebble Jun 20, 2025, 1:48 PM

#

Ok, I will hit that one today and track progress

Looks like a good flash

#

You should see it now

autumn pebble Jun 20, 2025, 2:50 PM

#

How do I verify at this point?

#

plucky gull Jun 20, 2025, 2:54 PM

#

well you put in the serial ID not the CAN UUID

autumn pebble Jun 20, 2025, 2:56 PM

#

so, how do I change that?

#

I did backup my system prior to jacking around with all this, so maybe I should revert to clean slate and start over?

plucky gull Jun 20, 2025, 2:57 PM

#

no need for that yet atleast but also a good plan to backup as you did.
I believe the MCU definition is in the main afc.cfg

autumn pebble Jun 20, 2025, 2:57 PM

#

Ok i have not done anything with that yet

plucky gull Jun 20, 2025, 2:58 PM

#

well take a look and see if there is an ID listed there.
you seem to have CAN connection listed atm but are wanting to use USB

autumn pebble Jun 20, 2025, 3:02 PM

#

yea I performed some Google-Fu because I was hitting issues with the CAN thing and probably dorked up something trying to poke and prod

plucky gull Jun 20, 2025, 3:15 PM

#

But you’re not using CAN lol

autumn pebble Jun 20, 2025, 3:17 PM

#

hence the confused chihuahua sticker on the post! 🤣

#

To further muddy the waters, I am not seeing the AFC.var file

#

#

oh wait, typos matter.....

west swan Jun 20, 2025, 3:25 PM

#

It's gonna be in your AFC_Turtle_1.cfg file, comment out the canuuid and uncomment the serial and put the full path for the AFC board

autumn pebble Jun 20, 2025, 3:25 PM

#

lemme try that

west swan Jun 20, 2025, 3:26 PM

#

autumn pebble

Don't edit these files here, only the ones from fluidd

autumn pebble Jun 20, 2025, 3:26 PM

#

ah

plucky gull Jun 20, 2025, 3:31 PM

#

As for the variable file it will be created when the printer boot successfully the first time and runs prep macro

autumn pebble Jun 20, 2025, 3:31 PM

#

Cool, great info

west swan Jun 20, 2025, 3:32 PM

#

Are you following this as well https://www.armoredturtle.xyz/docs/boxturtle/initial_startup/01-overview.html

autumn pebble Jun 20, 2025, 3:34 PM

#

Nope, havent seen that one

#

I suppose reading would help

#

However, after changing AFC_Turtle_1.cfg I get a fluidd error

west swan Jun 20, 2025, 3:40 PM

#

It guides you through where to edit everything

autumn pebble Jun 20, 2025, 3:40 PM

#

west swan Jun 20, 2025, 3:41 PM

#

What's the error?

autumn pebble Jun 20, 2025, 3:41 PM

#

west swan Jun 20, 2025, 3:41 PM

#

Ah, what are you planning on using for your toolhead sensor?

autumn pebble Jun 20, 2025, 3:42 PM

#

imma slow copy/paster, but i will read through that series of pages before i tinker with much else.

autumn pebble Jun 20, 2025, 3:42 PM

#

west swan Ah, what are you planning on using for your toolhead sensor?

Yes?

#

lol

#

Perhaps that is an issue that I have not considered....

west swan Jun 20, 2025, 3:44 PM

#

autumn pebble Perhaps that is an issue that I have not considered....

Well since your using the same machine as me ,just do what I did and use the turtleneck, but put rubber bands between the PTFE tubes.

autumn pebble Jun 20, 2025, 3:44 PM

#

oh, yea, I already got that put together

#

haven't done anything with it yet, should that be noted in some config file?

west swan Jun 20, 2025, 3:45 PM

#

In your AFC_Hardware.cfg

autumn pebble Jun 20, 2025, 3:46 PM

#

Gotcha, so its probably in that documentation that i have failed to read

#

Tenor

west swan Jun 20, 2025, 3:46 PM

#

But if you want to use the buffer as your toolhead sensor in AFC_Hardware.cfg put buffer as pin_tool_start and it should get rid of that message

#

Ok back to work I go

autumn pebble Jun 20, 2025, 3:49 PM

#

haha, me too.....

autumn pebble Jun 20, 2025, 4:43 PM

#

ok sweet, it seems now it is at least recognized!
Back to reading....where is the comic book version of these instructions? 😅

autumn pebble Jun 20, 2025, 5:19 PM

#

Well, I suppose since the AFC-Lite is now flashed, I can close this one!
Thanks @west swan !

#

@plucky gull @shrewd flower Appreciate your assistance!

plucky gull Jun 20, 2025, 5:52 PM

#

autumn pebble ok sweet, it seems now it is at least recognized! Back to reading....where is th...

double check you got everything plugged in correctly

west swan Jun 20, 2025, 6:03 PM

#

Or the switches are not standard as the LDO kit and it's just a config update

plucky gull Jun 20, 2025, 6:04 PM

#

ah yeah fair, formbot kit

autumn pebble Jun 20, 2025, 6:04 PM

#

Yea, I'm still building the rest, just got tripped up with this flashing portion

plucky gull Jun 20, 2025, 6:04 PM

#

ah so its not wired?

autumn pebble Jun 20, 2025, 6:05 PM

#

No, that's next!
