Describe your issue:

Hi Guys, ive Built myself a Voron, and now im stuggling with the config file…
i have done all the software flashing and everything is showing up where it should, but this thing with “Unable to parse option ‘max_temp’ in section ‘extruder’” i dont understand what this means? i would be really greatful if someone could take a look at the klippy log and see if they can see what i have missed.
thanks in advance Nick.

You may take away the empty lines and the indentat6ions in front of the [tmc2240 extruder] block.

Hello Eddy, Thank you for the quick reply… i have removed the section for the 2209 driver completely and then the empty lines, i have also removed the endentations from infrront of the tmc 2240 extruder, save and restart and i get the same error message.
i have no probe connected as i will be using klicky and im not sure if i need to change the sensor type? i have an NTC 100k Thermister 3950

Did you use

in your configs or

?

Post both current extruder related sections here using the preformatted text tag.

Next time please use the preformatted text tag as requested:

At least your are missing the square brackets around the tmc2240 extruder section.

[tmc2240 extruder]

Could you please upload a screenshot of the exact error and a new klippy log?
The original somehow complains about lost connection.

Looks like you have a more serious problem than only the parsing error.

sorry for that, and thank you for showing me how to use the preformatted text funtion.
the title of this discusion is the exact error message that i get.

so i removed the spaces infront of the [tmc2240 extruder] block and now i got a new error message"mcu ‘mcu’: Unable to connect" ive looked through both config files and i cant see anything wrong, but if im honest i dont really know what im looking for. i have double checked all the wiring and pin numbers and everything there is correct as far as i can see from the documentation in the voron design site. i have uploaded the latest klipper file if some one has the time to maybe have a bit of a look through it and see if they can see what im missing i would be very greatful

Can you provide a recent klippy.log please

[mcu]
serial = usb-katapult_stm32h723xx_060022001051313236343430-if00

This must be the complete path:

/dev/serial/by-id/usb-katapult_stm32h723xx_060022001051313236343430-if00
13

yes i missed that thank you, but there is still something else… im still getting the mcu unable to connect.

14

The serial seems still to be wrong.
Never saw it with this usb_katapult.

Where did you get this?

Even if it’s tedious: But if you fixed something and you get a new error, please attach the klippy.log

This error was present all the time. Mentioned that already.
He should query the IDs as in the configuration documents.

life of brian, thank you, you were right! the serial for klipper was still with katapult in it and not klipper have now updated and got a new error.

19

it now runs thank you LifeOfBrian for making me look again at my serial id’s and thank you EddyMI3D for seeing my mistakes with the mcu and the tmc2240 extruder block, i found a wrong pin number for the adxl sensor too but now klipper starts.
tomorrow i will see if i can get it to print. :slight_smile:

Nice to hear when it works now!
Such things happen especially when you are new to Klipper.

I can’t even tell you what I have overlooked two days ago that cost me a couple of hours… :smiley:
