K1 SE Support (and what i need to edit to convert it to a K1C)

[kcarbuncle]

Hello, going to ask if the K1 SE is already supported?

and if anyone has any or some experience, what's needed to make it close to a K1C. I already have the two fans (rear fan and side blower) and the thermistor (a regular 100k ender 3 part which i think is correct/similar) and just wondering what to watch out in modding them back in to enable them.

[pgallent]

I'm planning to do just the same.

Maybe with all parts attached to the printer, could be enought just flashing firmware with K1C firmware?

[kcarbuncle]

FWIW, i enabled root and checked the stock printer.cfg and there's not much difference against the stock K1C config file, with the only difference is that the pin assignments for the two fans and the thermistor, and the temp control for the back fan being commented out.
Every other file seems to be the same (some even sharing names).

have not tested replacing the whole klipper using the helper yet but I already collected the three parts, and with the stock firmware/klipper i can make the chamber thermistor show up/actually work in the creality print details tab (doesnt show up in the web browser version), and enabling any of the fans on the web version crashes the printer (and had to do a full restore to get it back) so it seems there's still something to change with the stock firmware to get them to work.

PS: For the chamber temp it seems it's just a regular 100k thermistor. I used the one for the CR-6SE hotend which looks to be the right diameter but seems to be just a little longer.

Thanks for your feedback.

In my case, I have both 2 fans, but cables seem to be quite short. I haven't managet to find a suitable extension cord, so I'm planning just cutting and soldering an extension. What did you do to get the cable to the mainboard?

In any case, I've been taking a look to the files too, It seems quite straightforward to add the thermistor and fans configuration, I haven't rooted yet, so I simply connected the lateral fan to the mainboard and tried managing it on the web browser. It didn't crashed but neither worked.

Anyway, I will do some testing during the weekend, I will report here any progress I make.

Thanks!

Well, just as an update @kcarbuncle . I've been adding both fans (waiting for the themperature sensor to arrive). I have arrived the same point as you.

I have tried updating the configuration files on
/usr/data/printer_data/config
/usr/share/klipper/config/K1_SE_CR4CU220812S12

That leads the printer to start throwing multiple exceptions anytime I touch anything related with fans (and with hotend motion too).

I will further investigate during next days (maybe I will manually install klipper from scratch as the next step, will see).

[pgallent]

Well, after doing some tests, I've managed to get the side fan working with Klipper / Mainsail.

Chamber probe and chamber fan continue conflicting between them. Somebody that has the K1C could confirm to wich pins in the mainboard are them connected?

Somebody with more experience with Klipper could help with the pins conflict? I attach printer.cfg and printer_params.cfg that lead to this error when starting Klipper:

klipper:pin ADC_TEMPERATURE used multiple times in config

printer.cfg.txt
printer_params.cfg.txt

Help with this would be highly appreciated.

Related to side fan, all I've done to make it to work is to uncomment the "fan2" section on printer.cfg:

[output_pin fan2]
pin: PB1
pwm: True
cycle_time: 0.0100
hardware_pwm: false
value: 0.00
scale: 255
shutdown_value: 0.0

And uncomment all fan2 related lines (not those related to fan1 (chamber fan)) on gcode_macro.cfg file.

Thanks.

[pgallent]

Ok, finaly working @kcarbuncle .

I had installed the Fans Control Macros from @Guilouz script helper (thanks for your work), and it was conflicting with default pin override on printer.cfg

I commented this 2 lines on default printer.cfg

# [duplicate_pin_override]
# pins: PC0, PC5

And now, fan1, fan2 and chamber temp probe are working fine.

I have uploaded on printables a remix from a previous fan duct from Rick Tucker to adapt the side fan to K1-SE:

Bonjour,

Comment avez vous rooté la K1SE car j'ai essayé avec les explications sur youtube d'une personne, et lors des installations des options après installé Fluidd, Mainsail, moonraker... j'ai eu un message d'erreur 2092. Quelles options avez-vous installé et non installé ? Quel firmware avez-vous ? Celui que j'ai est le dernier pour ma part. Merci.

[pgallent]

Hi @fred28tft .

Just copy the default K1C configuration files you will find on:
/usr/share/klipper/config/K1C_CR4CU220812S12/

Then, install the Fans Control Macros option from Helper Script.

On tools menú, activate the option to prevent Updating Klipper configuration files:

And then, reboot.

Once rebooted, go to
/usr/data/printer_data/config/printer.cfg

And check that file has all this includes on it:

It should work flawlessly, let us know.

[fred28tft]

Ok merci, par contre comment je copie /usr/share/klipper/config/K1C_CR4CU220812S12/

Quand je suis sur le ssh avec l'imprimante ?

Ou comment s'il vous plait ?

Merci,

[pgallent]

Execute this commands on the terminal:

cd /usr/data/printer_data/config
cp /usr/share/klipper/config/K1C_CR4CU220812S12/* /usr/data/printer_data/config/

That should be enough.

Ah, and sure, you have to be connected to the printer through SSH.

[fred28tft]

Sur le terminal de mon mac ou windows ou sur Putty ou MobaXterm ?

[pgallent]

It doesn't matter, the terminal you feel most comfortable with.

[fred28tft]

Ok merci, j'ai compris comment procéder. merci beaucoup.

[fred28tft]

dernière petite question , peut on installer d'autres options ?

[pgallent]

As far as I have tested, yes, you can go ahead.

Once you have installed the chamber probe, the auxiliary fans and you enclose the printer, the printer is basically a K1C.

[fred28tft]

Ok, mais dans le ssh script , install menu , improvements , peut-on installer les option n° 6, 7, 8 , 9 , 10, 11, 12, 13 , 14 ,15, la n°9 je l'ai installé FAN control Macros ?

merci,

[pgallent]

I haven't tested all of them, but I think you shouldn't have any problem.

In any case, so it's booting now without errors after updating the configuration files?

You can see the fans/chamber temp on Fluidd/Mainsail?

As far as I have found, we're the first ones getting K1-SE upgraded to K1C, I haven't found any other reference nowhere.

[fred28tft]

Oui c'est bizarre que personne d'autre ne veut la rooter et l'utiliser comme une K1C. Sinon pour le moment, je n'ai pas encore regardé, je m'en occupe demain car ma machine tourne en ce moment, elle est en print...
Mais merci pour tout, je vous tiens au courant demain si tout est ok.

[DaneGer21]

I have all the parts for the conversion. Heck I even have a mainboard, and I’m still to nervous HAHA

[pgallent]

Could you please give me the final code list of things you changed. B3cause I wish to do this upgrade too

Hi @ConradPrinter , here are each of the parts, but keep in mind that I had to adapt the length of the fans cables, and in the lateral fan and in the temp sensor, I had to adapt the connection to the mainboard:

Lateral fan: https://es.aliexpress.com/item/33021068426.html
Exhaust fan: https://es.aliexpress.com/item/1005002597347156.html
Temp sensor: https://es.aliexpress.com/item/1005003175884946.html (any NTC 100k thermistor should work)

For the enclosement, initially I bought some plastic panels and cutted them by hand, but I was not satisfied with the result, so finally ordered the parts sending the model files to a laser cutting service web, this one in mi case:
https://planchasdeplastico.es/producto/policarbonato-transparente-3-mm/ , if you go to the footer, you will find the pages for each european country.

Regarding the files, it's easier that we initially thought, you can just copy the K1C configuration files that you will find in your printer under this directory:

/usr/share/klipper/config/K1C_CR4CU220812S12/

Then, you just need to copy all it's content to (make a backup first):

/usr/data/printer_data/config/

Finally, in order to get working all the fans and options on the interface, you will need to install with the Helper Script Fluid/Mainsail. You can continue using the Creality web interface and app, but you will not be able to controll the new hardware.

Additionally, you will need to update the printing profiles (I've been using Orca Slicer) to the K1C ones in order to use the fans during the printing process.

And I think that's all.

Best.

[ConradPrinter]

Thank you very much for that.
just a couple of questions:

1. which voltage and type of the fans do i get?
2. Can i use MobaXterm?
3. do you copy all the files at /usr/share/klipper/config/K1C_CR4CU220812S12/ or just the printer.cfg file?
4. how do you copy the files to the new location, which option do i click after right clicking on the k1c config files (see screenshot below) or do you do it a different way?
   
5. when you say back the files up do you mean the k1c files or the old k1 se files? and when i back them up should i just save them to desktop or should i save them on the printer and if so where should i save them?
6. also when i copy the files to /usr/data/printer_data/config/ i presume i should delete the previous ones and replace them with the new ones?
7. and finally which board and which pin assignments do i plug the fans and thermistor into? also which adaptions for the mainboard do i need?
   Thank you very much for the time you put into this and sorry for being a pest.

[xlyz]

one last question:

8. where the thermistor is supposed to go?

thanks in advance

[mryusufcan]

Did you get the answers? Would you mind sharing them?

[ConradPrinter]

no, i am still waiting for the answers from pgallent

[milczas]

I also installed fans and a thermistor, installed walls, doors and the upper flap. I added a camera. You could say that it is transformed from k1se to k1c. I use orca sliker along with root and clipper. There you can regulate additional fans and see the chamber temperature. I want to modify the software so that additional fans and the chamber temperature are visible on the LCD printer panel. I wonder what should be changed in the printer software. Thank you in advance for any help.
PS
I have both K1C and K1SE printers and if anyone is interested, the motherboard is identical in both.
I also modified two fans at the bottom, i.e. the power supply and the motherboard. The cutout in the power supply is the fan strainer and the lower flap fan strainer. The fans are practically inaudible due to the cut-out hole in the flap, I printed a cover that sucks air from the side holes, I can provide the STL
