Unable to read tmc uart stepper register GCONF

[narrow steeple]

Building a 2.4 350 first time. Started motion testing & configuring sensorless homing but,

I am getting: Unable to read tmc uart 'stepper_(axis)' register GCONF

Upon running DUMP_TMC STEPPER=stepper(axis)

on y, z, z1, z2, z3 except x

I have octopus v1.1 | tmc2209 | nema17s
I have verified the uart jumpers, tried swapping drivers, tried swapping motor ports between x/y - error remains same.

I read it could be a power issue, so currently my wiring is:
24v + - to 2 wagos which connect to motor power & power of btt octo
24v + - to usb adaptor board of sb2209 usb
24v - to a wago which shares rpi usbc - & 5v v-
24v + unconnected screw
5v + to rpi usbc
Hope the wiring explanation is understandable. Photo is also attached.

I have verified the dc output of both PSU's: 24v is giving exactly 24v & 5v is giving 5.01v

I do not even know how to begin to diagnose, klippy log is also attached.

I am happy to provide any more details if needed.

Bit of an abnormality here:

[mcu]
serial = /dev/serial/by-id/usb-Klipper_stm32f407xx_440054001150304235343520-if00

I just discovered that all my pins are wrong except x

[slender rock]

The octopus isn't a stm32f407...

[narrow steeple]

mine is 32f407 - followed the config here: https://usb.esoterical.online/hardware_config/STM32/BTT_Octopus.html

[slender rock]

Huh. I didn't even realize that version existed

But okay

If all your pins are wrong, what config file did you start from?

You also have uart_address lines in your config, which isn't normal for the octopus

i actually started with chatgpt which i am realizing now was a grave mistake

[slender rock]

Its interesting how chatgpt evolves. Like, used to be, it would make up entire keywords, so it didn't matter much. The config wouldn't load, you'd realize it sucked, and move on

Now it's gotten to the point that it gives you something that actually loads. And that's far more terrifying

What if it comes up with something that defaults to turning on all the heaters full power?

Wreck your hotend before your printer ever even moves...

Anyway. I'd really encourage you to start with the config we provide (github or docs.vorondesign.com) unless there's one from a kitmaker

[narrow steeple]

Fixed all axes except z1 - getting the same error. Not marking resolved yet. Sharing updated cfg

[slender rock]

I didn't check your actual pins, but your notes say z1 is in m3

[narrow steeple]

isnt the highlited section motor2_2 and above it duplicate driver 2?

https://teamgloomy.github.io/images/btt_octopus_1.1_pins.png

[slender rock]

There is no duplicate driver

there is a duplicate OUTPUT on a single driver

so 2_1 and 2_2 (ports) both connect back to the M2 driver slot, and then the next slot is M3

[narrow steeple]

I see, I was following this image

So I am not supposed to skip the driver slot (tmc2209)?
I have to skip only the port?

[slender rock]

Look at the image....did it skip a driver?

[narrow steeple]

Nppe it didnt .. I didnt even realise it has drivers.. I thought its bare 🤦‍♂️ 🤦‍♂️ 🤦‍♂️

Thanks I ll test tomorrow and most probably mark it solved

[slender rock]

just doesn't have the heat sinks installed for some random reason

uhh.....don't follow the image on THAT 😛

[narrow steeple]

Lmao I didnt thankfully
