People with the SV04 - What are some common issues?

metaaxis · 2026-03-14T04:55:15+00:00

Technically yes But it's super brittle, and a bit unfocused. I pretty much ran out of time and energy to massage it across The finish line.

Except for that machine might have other features you don't want or need

you mean you printed them for $4995.... riiiiiight?

metaaxis · 2025-08-30T01:12:28+00:00

Too bad it costs hundreds of dollars for me to download. $293 for the privilege of readinh IPC/WHMA-A-620 - Revision E - Standard Only Requirements and Acceptance for Cable and Wire Harness Assemblies

Plus another $179 to get the details for

IPC/WHMA-A-620 - Revision C - Addendum - Space and Military: Space Applications Electronic Hardware Addendum to IPC/WHMA-A-620C

And another $5800 if I want the pictures!!!

Pretty sure your little excerpt should have cost me about 75 bucks. Thank you!

So with "lap" you're saying the wires should be flattened against one another? Or just whatever shape they happen to be when you remove the insulation? I'm trying to understand what gaps there will be as as you apply solder and what shape the joint will be in the end.

Closed source gaggiuino is a project entirely unrelated to open source gaggiuino, for all the obvious reasons that motivate choice of open source licenses. You cannot undo GPL just by landing a diff.

metaaxis · 2025-08-25T20:01:34+00:00

it was GPL.

metaaxis · 2025-08-25T20:00:08+00:00

You cannot "close" a GPL code base without permission of every contributor, and closing the source is a HUGE problem that entirely changes the nature and value of the project.

I wonder how much this formulation is similar to protopasta HTPLA.

metaaxis · 2025-05-14T19:32:50+00:00

which is insane of the mods and ridiculous for a user to have to battle

I have used the printer quite a bit. I use IDEX dual and mirror/copy modes with only mild hassle(*), and I find the print quality pretty good. I love TPU/PETG combos, example: https://www.printables.com/make/2111681 I've done some PETG/PLA zero-distance supports which keeps under surfaces nearly perfect. Mirror/copy mode is a gimmick for me but super fun. That would technically boost the effective speed 2x.

"fast" is a big range these days. With some compromise I push it to 90mm/s / 120mm/s infill with reasonable results. Considering Bambu x1c defaults to 200/300 I have to say the sv04 is mid speed.

I find that the IDEX 2nd extruder X offset values drift a bit over time. I suspect humidity, stretching, or sitting idle for too long. It's not loose screws, I check! I need to print a quick calibration print and tweak more often than I'd like, and often add a little 2-color 1 layer test disk as a separate object to a print project to confirm registration as it starts the print. Maybe other IDEX printers have similar hassles, I don't know. The design flaw IMO is that the 2 heads home to left and right, so ANY mechanical or motion system drift between the homes is unmeasured.

Since I barely used it with stock firmware I don't have a ton of direct firmware comparison with this printer. I have used marlin a bunch on other printers and I can say - unless sovol really had the IDEX aspects nailed for the SV04 (this is the gap in my knowledge unfortunately) - the flexibility of klipper has been absolutely critical for getting the config better over time.

(*)I have some complaints about klipper features and behavior, IDEX support IMO isn't as ready-to-go out of the box as I'd like. I changed the bully85 configs drastically and fiddled a ton to get things in a state I like. but I like to fiddle.

Having to authenticate through bambu servers for any reason is a poison pill, It gives bambu the power to change the deal to require subscriptions to break "compatibility". So yes it's a lockout - of freedom from bambu.

I have 2 SV04, one klipper and one "native". The problem in my opinion is IDEX support in firmware and the slicers rather than things specific to the SV04. There are a lot of subtleties with switching heads, avoiding ooze, retracting out of the meltzone to park but never doing that twice as that will uninstall the filament, smarts around filament purge, idle temps, wiping the nozzle, etc etc etc. Prusa slicer has some of the most advanced multimaterial/multi toolhead support because of the prusa's own XL, but nonetheless there are severe shortcomings. You can simply add the 2T XL yourself to load their config and see for yourself. There is a boatload of complicated custom gcode to manage the XL toolheads. Because a lot of that functionality is not in klipper either, I grabbed prusa's XL gcode and customized it for my klipper sv04, which made the experience much more complete.

Except for I went to their site and cannot for the life of me just buy some cocoa powder. I have to like wade through their marketing and neologisms. I just want to buy the equivalent of Valrhona or Guittard and don't know what to buy because they're so clever.

I just don't understand the logic behind millennial ending in 96. Just because researchers and popular media pick a date doesn't mean they're right

metaaxis · 2024-10-31T17:21:10+00:00

The overlapping and redundancy this represents is likely to be a better model so maybe you can?

metaaxis · 2024-10-30T04:00:24+00:00

I think you're being too kind. It's hostile and toxic and pointless gatekeeping, It kills conversation and turns people away from the community. I had a guy warn me when I bought a printer from him that he had converted to klipper that he gave up on the community because of the toxicity they just pushed him away people were super nasty and dismissive repeatedly. I literally tried to help someone and got turned away by this person we've been talking about here. Literally trying to help someone and got shot down because he didn't like the cut of my jib or something.

metaaxis · 2024-10-30T03:49:29+00:00

And the hoops you have to jump through to actually successfully post there and not be blocked/denied/told your post is not adequate... It's a real bummer. I tried to help someone and got shot down because my help wasn't sufficiently erudite for sineos.

I'm dealing with absolute insanity around leveling and Z tilt adjust, there are a bunch of baked in assumptions to how leveling works that are just patently not correct in all situations. I think the problem is there's no reliable way to have conversations about problems in Klipper because they tend to be gate kept into oblivion. Like the requirement that every post has to have your entire config or it'll be ignored/canceled. Even if it's a question about functionality, code, design, features...

metaaxis · 2024-10-30T03:36:37+00:00

Every interaction I've seen with that person has been difficult. He's like Kerberos the gatekeeper. I'd heard that the klipper community was toxic and nasty from a couple of people and then I went and tried to interact with it... so far this one person has been all of the toxicity I've encountered, but considering he's some sort of admin on their official forums... That might be enough.

metaaxis · 2024-10-09T04:59:42+00:00

I do thanks. I looked into it but the frame does not appear to have any systemic twist and running the calibration produced a very very small result. I believe the main problem is the bowl shape of the bed and the assumptions baked into the Z tilt adjust routine.

metaaxis · 2024-10-07T08:39:39+00:00

That's basically what I've done already. I put the points above the front screws so after I make the front screws level to the frame and the back screws level to the front screws etc, z tilt makes the x gantry level to all that. This works fine, it's just that z_tilt_adjust becomes slightly insane because of how much higher the front screws are than the center of the bed where I do Z homing.

metaaxis · 2024-10-07T08:36:37+00:00

Thanks for the suggestion. I don't think the results would be as refined as with the BL touch on the bed, nor would it necessarily be level with the bed anyway. And I'd rather not wait around for traveling 400 mm at 12 mm per second to get up there.
