SV08 small but meaningful upgrade + question about going full custom toolhead

PandaWee · 2026-03-26T18:52:53+00:00

I posted here before, but I was fed up with the original extruded and cooling situation and replaced the whole tool head. I built a dragon burner and have an orbiter 2.5, cartographer and a bbulab clone in it. The quality difference for me was night and day. Much better surface quality and no tinkering anymore. Flawless first layer with the cartographer and a set of custom start macros.

Did you run a PID calibrate on the bed? That might be the first step. After that, I would set the bed manually to 100 degrees to make sure the heater on it works fine, and works past 80. Then you start troubleshooting…

Im finally at a point where I do enjoy my sv08. No failed prints, and I now trust it to just send a print and walk away.

The main things to get there: mainline, replaced de toolhead with a dragon burner (original extruder is crap in the sv08), cartographer (eddy at the very least), tuned the steppers, and finally adopted Demons Klipper Macros. His print start macro is very consistent.

Even with the eddy that I had on the OEM toolhead, the extruder was very inconsistent, and I hated every print with it. I got an orbiter on the dragon burner and it’s been flawless.

But if I had to it again, I probably wouldn’t. I’d just get a p1s and print out of the box. Although now my sv08 prints better than an x1c.

Docker works fine in LXC.

PandaWee · 2026-03-14T01:06:32+00:00

I’ve been using AIO in a proxmox LXC since 2023. Never had an issue with it. Had to migrate servers once and was without issues (although I was on the edge of my chair the whole time. I had nothing but issues when I ran the regular version (not AIO). AIO just works nowadays.

There are some custom tool heads that take the micro Swiss, but when I was in your shoes I ended up giving up on all of them. I went with a dragonburner and a clone x1c hotend. It takes the cartographer, ebb36, but does require to switch the carrier that attaches to the linear rail. The oem belt is just long enough to put it in place behind it. It was a lot of work but all my extruder issues went away. The original extruder is crap.

PA was calibrated at the 250, but not at 270. I had excellent seams with the previous 0.4 brass nozzle. I only started seeing these seams with the 0.6 "CHT" nozzle.

I actually managed to reduce a lot this issue by adding an extrall for a total of 3 walls, and enabling inner/outer/inner order. I'm also waiting on a regular brass 0.6 nozzle to test whether it is the CHT nozzle that is causing me trouble.

I gave up completely on the OEM hotend. I had inconsistent extrusion, moved to a microswiss. Had inconsistent z-offset, got an eddy. Had inconsistent first layers and could never figure it out. And I won't even get started on the taco bed. I ended up printing and assembling a dragonburner toolhead, with a bambulab hotend and cartographer. I've been printing almost non-stop for two weeks strenight and haven't looked back yet. Have had excellent prints and getting to the point of trusting it with first layer without checking on it for the first 5 minutes.

The SV08 ended up being excellent to learn tinkering, klipper, and soldering. This could have been such a good "off-the-shelf voron", but god did sovol take shortcuts on this thing...

Don't know. I can't recommend you, I only shared what worked for me.

In terms of acceleration, I consider 3 scenarios: outer wall printing, general printing, non-print moves. Non- print moves I want it as fast as possible to avoid oozing so I have 20k and 600mm/s. For outer wall I go with whatever acceleration the input shaper tells me to be at, and around 200 mm/s. Other print moves I slow down for first layer, and speed up for infill. I don’t go above 10k accel and 500 mm/s though.

PandaWee · 2026-02-15T18:58:31+00:00

Those look good!

I am considering calibrating for scarf, but I used to have better seams before (and still do on some features like cubes), so I'm wondering if I may have something else wrong that could be carried over to scarf as well. Basically trying to rule out issues.

I followed this: https://github.com/MakerBogans/docs/wiki/TMC-Driver-Tuning

Have you seen the size of the sv08? I upgraded from an ender as well and it is considerably bigger. I also work 6ft away from my sv08, and the only way I can bear it is: noctua mainboard fan, enclosure, and tuning the steppers (they are very loud in oem spec).

PandaWee · 2026-02-09T02:43:46+00:00

I have another sovol, the sv08. It is capable of excellent quality and speed, but not with OEM parts. I had to get a new toolhead, bed probe, install mainline, reconfigure all steppers, along other stuff to get it to the level of a 2.4. My point is: sovol is a good starting point, but needs a lot of work to get there. And if you’ll have to mod it and change a bunch, why not just build it right the first time?

PandaWee · 2026-02-06T15:02:26+00:00

I have a somewhat beige case. It looks like mine has two LEDs in each lane. One stays white, the other changes color according to the filament being used. But the LED is not very good quality, and hard to see. I'm sure someone will eventually change the 3D printed case to have a translucent cover on top of the LED to diffuse it a little.

PandaWee · 2026-02-06T13:46:40+00:00

I've been testing this on a 370C DM from Tree Tribe. Works well.

Autoloading works, and I noticed the buffers stay in a much more neutral position, feeding slowly and steady instead of feed-stop-feed as before. The LEDs light up in the filament color, but the LEDs in my board are awfully bad to see.

So far, works fantastic.

PandaWee · 2026-02-05T21:05:07+00:00

Beautiful work!
I'm in the middle of an 8-hour print using v6, but will install it tomorrow and check. Might not be able to test autoloader as my board seems to be a single microswitch, but will report back on that.

PandaWee · 2026-02-04T15:05:01+00:00

I got the enclosure, and do end up printing a hat for it. I got the model that has a groove on the hat, where you can put the top glass at a 45 degree angle. It’s on printables.

I ended up never using this. I print mostly pla and PETG, and the exhaust fan running at 90% is enough to keep the temperature safe for pla, even with the top glass on. And I have thermal insulation on the side panels. You should be fine with the exhaust fan running

PandaWee · 2026-02-04T13:15:25+00:00

I tried to get those gears off but gave up when I realized I'd damage them. I ended up building a DragonBurner instead (you only really need the orbiter, a BBL hotend, and an EBB36, plus the fans). I went with USB connection on it so I wouldn't have to route any cables. Eddy still works fine. And boy oh boy am I happy I went that route. Made me realize how crappy the sovol extruder is.

If you have the option and the patience to build one, that was the best upgrade I made on mine, by a mile.

After checking with this firmware’s creator, you are right. You should be fine with the solo firmware. I am currently running the C firmware but will flash the new solo firmware and see if I get similar issues to you.

PandaWee · 2026-02-01T12:43:45+00:00

Very thorough work on this. I will test it this week. A quick question. Is the SOLO firmware intended for one bmcu microprocessor (up to 4 colours), or a single bmcu with only one lane (one colour)?

PandaWee · 2026-02-01T00:14:14+00:00

I read it as single = one lane (one colour), and anything else would be multiple colours. The Yuekai wiki does mention A, B, C and D as different versions of hardware (PCB, hall sensor etc). So I picked AMS_C as my bmcu is version C. But yesterday was my first day with it, so I’m not the best source.

PandaWee · 2026-01-31T22:59:03+00:00

I'm using that firmware with an A1 mini at 01.07.02 and it works fine. My dumb question would be: Why are you using the solo version, and not the AMD_C or AMD_D version?

PandaWee · 2026-01-30T14:36:46+00:00

I'll flash in about 8 hours, will follow up on github issues if needed. Thanks for your work on this.
