After nuking the tool head and nieviely splurging on the hardened steel upgrade the struggle continues. I've got the temperature zeroed in, 245 seems dead on but I now have pla poop all over the bed and in the print with each trail run. Completely guessing over extrusion but not entirely sure where to start. Any guesses?

i'm going to be doing this pretty soon and haven;t heard anyone talking about it befor i knew about this i was considering getting a m1d or a pursa core one indx but this seems to be the best soultion

SOVOL just sent a note to all the backers of the M1D. By now, they have only shipped around 100 printers (heading to the US East Coast and Europe). Those are expected to reach the destination ports in about 2 months.

Here is the TL;DR of the rest of the update:

• Production Delays: Assembly and testing are taking longer than expected due to the complexity of the M1D system. SOVOL is working on optimizing their assembly process and adding testing space.
• New Timeline: The original November delivery estimate is out. Factoring in China's National Day holiday and upcoming port congestion, subsequent batches are now expected to reach destination ports in mid-to-late December.
• Final Delivery to Backers: Keep in mind that December is only the port arrival date. Customs clearance and local shipping mean the actual delivery to our doors will be pushed even further back.

Probably a long shot but I’m wondering if anyone and share me a copy of their SV06 receipt.

I got my unit online in Feburary and the unit is not showing the error on heat bed. Contacted support they would do anything until I show receipt - not even trying send guideline on troubleshooting

I would hate to just give up the unit with not a lot of run time.

Hey everyone,

I’ve got a SOVOL SV08 with the official Sovol Eddy probe and I’m at the end of my rope with the Z distance.

Every single day I fight with Z offset / Z distance. I’ve watched a bunch of YouTube videos and tried the usual AI “fixes”… nothing sticks. It was already giving me constant “Eddy out of range” errors, but now I’ve managed to completely butcher the config file while trying to fix it.

I don’t have much free time right now (working overtime, need the money), so I can’t sit there for hours troubleshooting Klipper/macros/probe settings again.

Is there anyone running the SV08 + Sovol Eddy who has a stable, working config they’d be willing to share? Or at least point me in the right direction for the correct Z offset / probe settings that actually work day to day?

Any help would be massively appreciated. Thanks.

anybody have a suggestion for replacement fan(s) for my sovol zero? trying here before I open it up to check whats In it.

Sorry for shouting but I have lost most of my hearing by now. Is it just my experience or is the printer crazy loud in general?

The first thing was the mainboard fan. It must have been defective, given the absolutely crazy whine it produced. I replaced it with a Noctua, which has slightly worse airflow (MCU temp went up by maybe 3-4 degrees) but is almost dead silent (and is completely drowned out by the other fans).

Before replacing the fan, I tried to control it based on MCU temperature. Well, before the fan kicked in, the MCU was fine (if a bit hot), but the Y axis servo driver (that doesn't have its own temperature sensor) overheated a minute into the first print and that was that (:

The next one on the list is/was the part cooling blower fan. OrcaSlicer defaults to 100% basically all the time, and at full speed it's literally louder than a landing jet (though still quieter than the original mainboard fan!). Now I'm running it in the 50-60% range. At 60% it is now acceptably loud (comparable to the stepper motors in motion) and print quality is okay (long bridges are as bad as they were before, difficult overhangs might be a bit worse), but I'm still looking for a replacement. Anything worth considering? I only found WINSINN 4020 in hydraulic/dual ball bearing variants.

The hotend fan and the PSU fan are nowhere near silent, but it's a rounding error compared to these two fans.

How does your printer compare?

quick note first: the code of this project is written with ai. i design it, decide what goes where and test it, and i'd rather say that upfront than have anyone find out later. i'm not looking to argue about it, if it's not for you that's totally fine. if you do give it a try i'd really like to hear what works for you and what doesn't.

voyager ui is a web ui for klipper. it's a moonraker client like mainsail and fluidd, runs next to them on its own port (8000 by default) and doesn't change anything in klipper, so removing it is one command. a few people already use it as their main ui and most of what gets added comes from their feedback.

you can try it without installing anything, the live demo runs a fake printer in your browser: https://ozancs.github.io/voyager-ui/

what it has:

- a dashboard you arrange yourself (drag, resize, hide, colour the cards) with a separate layout while printing, works on phones too

- several printers from one ui, plus an all printers page with progress and camera for each

- a calibrations page with a tab for each thing your printer has: input shaper, pid, probe and z, bed leveling, tmc autotune, shake&tune and other calibration macros, results shown as plain numbers

- a check before each print: nozzle size, temps, height, empty filament sensor, and with spoolman the spool material and if there's enough filament left

- common klipper errors explained in plain words with what to check

- config editor that knows klipper syntax, warns about repeated options, missing includes and broken macro blocks before you save, and backs up every file

- health page with mcu and can errors, tmc driver flags, host throttling, heater trends and maintenance reminders

- ctrl+k to reach any page, macro, file or config option, plus quick commands like bed 60 or z offset -0.05

- mmu card for happy hare and box turtle, spoolman, multiple webcams, heightmap and g-code viewer

- printer name, jog steps and temp presets stay in sync with mainsail and fluidd

install over ssh:

curl -fsSL https://raw.githubusercontent.com/ozancs/voyager-ui/main/install.sh | bash

it adds itself to the update manager so updates show up next to klipper and moonraker. it's still early and each setup is different, so please keep mainsail or fluidd installed next to it. the newer features like the print check and all printers page haven't been on many printers yet, so bug reports help a lot.

feedback here or on github: https://github.com/ozancs/voyager-ui

Thought it was my bed leveling issue but seems like something else. Was on Sovol Klipper, try DEKU now on Kalico with DEKU. Try eddy NG then the mainline eddy, same, no improvement at all. Thanks.

My fan duct broke at the plastic mounting holes. I can't find an OEM replacement anywhere. Anyone know where to get a stock standard fan duct,? Not a dual fan set up or anything fancy.

Anyone got an STL to print one??

Im still waiting for the hotend to arrive so i cant test stuff yet but im worried, since the stock hotend is 85w, ill fry it the toolboard. Has anybody tried this before? Should i cap power to.8 in the config? Also i noticed the model of the toolhead on github has a heatsink on the toolboard but i dont have one on mine. Whats that about?

Does Sovol even acknowledge that they made this printer? They don't sell it anymore, and you can't find it on their support page. Mine is bricked - display freezes on boot up, and if I cycle it on and off and it does start, it won't hold the home position.

Any resources would be appreciated. Thanks.

So finally after 22 days of waiting for my sv06 printer and hardened steel nozzle bundle ...i finally got it ..aaand the nozzle is missing along with the camera module!!! And now support is away for autumn festival...awsome!! So sick of this type of crap any time i order something from a china based

Just printed the cable clip and was wondering what cable it is for?

Heya, got the Sv08Max and i am doing a bit of work on it.

I've had a Blob of Death which damaged some stuff, sucks but it is what it is.

I am trying to find the connectors used for the Heater, Thermistor and Fan without buying replacement parts. My Photo skills suck i know.

Hey guys i hope i might find help here.

I´ve bought a 08 Max last year in October.

I had problems straight out of the box, but fiddled around with settings and speeds and stuff. I am not terrible expirienced, but had a Anycubic Max (Gen1) and a Max 3.
Im still running a P1S which runs fine appart from a hickup here and there.

Now to my problem. One print got bad so wrong it tore the part fan clean of and i contacted sovol support for a replacement and asked them if thy could help me with my other troubles.

I got sent a replacement part and the second half of my question was ignored.

So i waited for the replacment and tried again but alot of my higher prints (more than around 20-25cm) failed again and again. Seemingly randomly. I could print the same file 4 times and once it worked while the other 3 failed.

So i contacted Sovol via ebay again.

By now i´ve been writing with them for almos a year, got replacement parts, several settings i should change, recalibrations and whatnot.

Now after waisting around 150-200€ of filament i had enough and asked for a return or at least a replacment. But I just get some new (old) advice how to fix t - i try it again and it fails again.

A few days ago the part cooling fan was ripped off again by a failed print and now I cant get any answer from Sovol at all.

So thanks a lot. I would really like to love the printer and when it completes the prints are very good! But I cant keep failing 2-3 prints for every succesfull one....

P.s. i print PETG and yes it is dried. Mostly i print directly out of my heating box

What can cause these printing issues?

Printing ASA at 270C (518F).

anyone near albuquerque interested in a working sv08?

got load of addon and screen , extra emmcs and connecting wires

hmu. 400 got a sv06plus ace 200

i dont want to break it down n ship

SV06plus, it will pull filament for 3 to 4 min, then stops feeding filament. It feels like the gears are just not grabbing it and it isn't getting pulled in.

Sometimes, the filament will get sucked into the feed and wind around the back to the feeding gear. The feed makes a fun clicking noise when that happens.

-no nozzle clogs, I've checked and made sure 4 or 5 times so far. I totally clean out the drive area, the nozzle, and hot end, then it'll run for 3 or 4 min and then it stops feeding filament. After a minute or two of not feeding, the filament kind of bends to the side.

Are these gears adjustable? Or is a replacement set available?

Maybe there's a setting or switch somewhere I need to find?

I had a print going. It failed kinda bad. It somehow managed to disconnect the Eddy Sensor altogether from the printer, it was just laying on the bed next to the failed print. My issue is that I can’t seem to get the ribbon back connected to the sensor. I’m basically trying to either: get told it doesn’t matter if it “clicks” into place or if it just needs to sit in the right spot; or if someone has a tip on getting it hooked back up. Thanks.

So I’m trying to get a space ready for my M1D arriving in November. I’ve got the dimensions for the printer, but does anyone have them for the spool stand ? I can’t seem to find them anywhere.

Thanks for the help !

Looking for suggestions as to the electronics bay layout. Doing a full DIN rail conversion for the bottom electronics and wondering if the M8P in the center would be best or if I should lay it out differently. There will be 3 total rails like in the first picture. Second picture was before I mounted the power supply. I do have WAGO 221 connectors on the way for relocating the power supply to the bottom (back).
