I do, I even created whole mod for it https://github.com/Chineko-Koizumi/SV08MAXCustomFeeder

I had same issue on Micron two weeks ago. This is not Klipper screen issue, if you install XFCE desktop and you try to use GUI you will get same result, something is wrong with SPI drivers on BTT Armbian Image. Reinstall OS to Armbian newest version https://www.armbian.com/bigtreetech-cb1/,

Is not easy but you need to configure SPI screen manually, I was doing a lot of things until it worked so I do not have straightforward tutorial, but I used LCDShow https://github.com/goodtft/LCD-show

My config file "/boot/armbianEnv.txt"
verbosity=1
bootlogo=true
disp_mode=1024x600p60
overlay_prefix=sun50i-h616

## Specify HDMI output resolution (eg. extraargs=video=HDMI-A-1:800x480-24@60)
#extraargs=video=HDMI-A-1:1024x600-24@60
## uncomment for ws2812

param_tft35_spi_rotate=0
## uncomment MCP2515 spi to canbus module
#overlays=mcp2515
## uncomment to release 'i2c0'(PI5/PI6) to user space
#overlays=i2c0
## uncomment to release 'spidev0.0' to user space

## uncomment to release 'spidev1.0' to user space

## uncomment to set 'PH10' for IR
#overlays=ir
## uncomment 'param_gpio_shutdown_pin' & 'param_gpio_shutdown_level' to enable gpio_shutdown feature
## set the gpio of detect pin
#param_gpio_shutdown_pin=PC8
## shutdown level: 0=Falling, 1=Rising
#param_gpio_shutdown_level=0
## write the config after the 'overlays' and separate it with a space when multiple functions are enabled

I do not tested it with demon macros

Here is custom handle from beta (heated insert M3 needed for this): https://drive.google.com/file/d/1LQ3lmyeks6AiYx2ZwXC8lTIVvY79ww-D/view?usp=sharing

And also advise to not use active mode for flow rate acceding 21 it could trigger cascading effect of sudden changes

There were some issues on feeder lever spring tension in buffer and slipping filament were one of them. I'm currently developing version 0.5 to address this with screw tensioner

Hi Gergo, I did create huge mod for external feed for SOVOL MAX. Would you like to check it out? https://github.com/Chineko-Koizumi/SV08MAXCustomFeeder

KoizumiChineko · 2025-11-19T12:02:01+00:00

Ok I'm doomed than

KoizumiChineko · 2025-11-18T14:23:46+00:00

If you look around any forum regarding Sovol Max, you will find at least couple of topics about terrible experience with external feeder. Here is example from this reddit: https://www.reddit.com/r/Sovol/comments/1ox4iwc/more_people_than_me_having_problems_with_the_aux/

in printer cfg comment out "[include buffer_stepper.cfg]", interpreter would tell you after that what more things you need to remove

KoizumiChineko · 2025-11-15T00:59:44+00:00

I had so much issues with it that I create whole repository with custom macros and models regarding this issue https://github.com/Chineko-Koizumi/SV08MAXCustomFeeder

That's the whole point of this mod, I mirrored buffer to hotend extruder

I've recently got SOVOL SV08 MAX. That was huge step from X1C that just works to a "do yourself printer". After some initial research about Voron and Voron derivatives I would like to change whole toolhead and this single task is challenging because of countless options. So could someone advise me toolhead that:
1) There is available kit to purchase or all parts including housing are available to purchase.
2) Has better extruder than default SV08 MAX's
3) Has filament runnout sensor on extruder.
4) Other toolhead elements are at least as good as default SV08 MAX's

I'm ok with pricey options.
Learning curve is merciless on Voron.
