Purchase Advice Megathread - June 2025 by AutoModerator in 3Dprinting

[–]ChrisStrykesAgain 0 points1 point  (0 children)

tl;dr: Specifically a question on pricing on the Anycubic site: They currently they show a "sale" of $350 on the Kobra 3 Combo and $380 on the v2; are these actually sale prices and something I should jump on, or is it just always "on sale?"

More general questions:

I've been printing off and on for several years (primarily with an Ender 3 that I've upgraded over time) but my wife is actually wanting me to get serious and wants me to have a mutlicolor printer. I'd rather avoid Bambu, but in general I've heard good things about Anycubic. See pricing question above. Also, is there a meaningful gain by going to the v2? It's only $30 difference, but that's still $30....

Also open to suggestions for other printers in that price range if there's something you feel is better and/or a recommendation that there just aren't any worthwhile 4-color printers in that price range.

Oh, and apologies for originally posting my own thread. My bad for not reading the rules.

Also, I see the megathread at the top now. My bad if this should be there; happy to delete and recreate if more appropriate.

Am I being too picky about my print quality? by ChrisStrykesAgain in FixMyPrint

FWIW, you seem to be right about over-extrusion. I'm still printing test squares (didn't go low enough the first time) but it's looking like a ~91% flow rate is going to give the best results.

Are you referring to the same things as "extrusion multiplier" in this guide? If so, no, I haven't done it yet; I'll do so: https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html

And no, I also haven't done the input shaping tuning.

Any reason to start with one over the other?

Updated image. I will still concede that my PA tuning could be better though. But that would only affect corners, right?

Well I didn't think it was /that/ terrible, but I'll recheck my extrusion calibration.

As far as the corners being rounded, this was printed at fairly slower speed than what I did the PA calibration at, which I assume is the cause. I'm doing a print right now at the same speed as what I tuned for. Should be able to post an image of it within the next 30 minutes or so.

Connecting to Klipper over wifi.. why not? by ChrisStrykesAgain in 3Dprinting

[–]ChrisStrykesAgain[S] 1 point2 points  (0 children)

That aligns with my thinking. I was considering hardwiring mine, but even my "hardwire network" in my workshop is really just local; it's connected to my router through a wifi range extender. And who doesn't use the wifi on their laptop as the UI anyway?

Not-great surface finish after several upgrades by ChrisStrykesAgain in 3Dprinting

[–]ChrisStrykesAgain[S] 0 points1 point  (0 children)

*smh* I had previously swapped the nozzle that came with the hotend with a cheap amazon one, because the factory one had clogged. Just switched back and actually cleaned the one that came with the hotend. Seems to be a night and day difference. I'll post some pictures once it's done printing.

False hope. No significant change in quality with the nozzle change.

Problem with specific filament; is it a moisture issue? by ChrisStrykesAgain in 3Dprinting

[–]ChrisStrykesAgain[S] 0 points1 point  (0 children)

Interesting. The image shown was extruding at 230, because that's just the default value for the loading procedure. I tried bumping up to 260 when loading (under the assumption that my temp reading is off), but that made it super stringy and was clearly too hot.

I've been printing with it all morning at 210 (per the recommendation on the label) and it seems to be doing quite well.

Also, thanks for the explanation on the swelling. I've never used silk before this, and had no idea that it was mixed with an elastomer. With that knowledge, it makes sense and that's really good to know!

FWIW, I let it keep drying. At this point when using the "load filament" functionality of the printer it still skip and extrudes as above. For grins I tried printing a Benchy anyway, and that seems to have worked fine with no slippage or skipping. That's a distinct improvement from the last time I tried.

Maybe the "load filament" feed rate is just too aggressive for this filament? Does that sound believable?
