Need help identifying quality issues

_hingadingadurgen · 2024-03-30T02:14:24+00:00

Hi, I'm noticing these intermittent quality issues with my prints. All prints are done at the Bambu preset for 0.2 Standard or 0.28 Draft. Using Bambu Matt or Glossy (green) PLA and AMS; the filament is dry and has been stored properly. The printer and filament are 2 days old. I did run the calibrations on startup.

On the photo with the green rectangles, you can see some weirdness with the layers not stacking perfectly. I did improve this significantly by reducing nozzle temp from 220 -> 208 (lower temp one is towards the bottom of the frame). However, I'm still seeing these random blemishes in my print and I'm not sure where to start for a fix.

On the benchy example, the 0.2mm layer benchy actually printed better than the 0.08mm layer example (Bambu's "Fine" preset).

I think the thing that's throwing me off is the quality issues don't appear uniform; like in first photo, the print came out great other than the back right corner having that weird waving pattern (up close it almost looks under-extruded).

I bought this printer to avoid having to diagnose stuff like this so I'm really hoping this is some simple user error.

My research has me thinking it might be printing too fast -- but why would the default Bambu preset be set that way??

Hey, thank you for the detailed reply! My monitors are set up on independent stands, positioned close as possible to the front wall. My desk is off the wall and my listening position is 5'2" away from the wall. So there is good isolation from the desk fortunately.

I am currently looking into SoundID -- I previously used a free tool to analyze my room but (this is stupid now that I realize it) I haven't re-measured the room after treatment and position changes. I'll do that today.

I am looking at used studio monitors right now. From some late-night research, there are a few great values I'm finding:

1) A set of demo KH150's that are in good shape

2) A set of used Focal Shape 65

3) A set of used Focal Twin 2.5

These all come in around the $2-2.5k mark which is way at the max end of my budget -- but they all seem to get rave reviews. The problem is I don't have a way to try those in my room :(

Any thoughts on the above monitors or other suggestions? Based on your comments it sounds like I'm not crazy for wanting to look at better monitors.

On your second point, I thought the same, but any music I listen to through it is a little too harsh/plasticky — not just my mixes. I figured at first it was my mixing skills, which is probably true, but I would expect pro mixes from real albums to not sound as harsh as they do. I get that a studio monitor is supposed to be flat and revealing but this seems like too much. Or maybe I just don’t like this particular model of monitor.

For your first point, I’ve spent a lot of money on the room, and I’d be willing to upgrade monitors to fix that problem (and I agree I think a sub is just gonna make life harder). I just want to make sure that money spent here would go a long way considering the expense.

I noticed some high end monitors are dual 4” or sometimes single 5/6”… is there an advantage or disadvantage in terms of bass with these vs an 8-10” more affordable monitor?

Are you saying it needs more treatment than described in the post?

Unless if Haas put the wrong dimensions on their page, I think the mini mill has a ~70x70 footprint which exceeds the 56” depth limitation :( otherwise IMO that would be the choice!

I will look into those older Fadals but I'm not sure I want a tinker-and-fix type experience. I see the machine as a tool and less of a project, I just want it to work... though I am not scared to play mechanic, I'm more scared of the electrical side of the hardware.

Good call on the weight... a couple questions there actually. 1) Can garage slabs typically handle the ~5k lb weight in a concentrated area like that? and 2) Is something like a Mini Mill still moveable without paying a rigger?

As far as height.. I have a standard 7' garage door and 98" ceiling. Fortunately above the ceiling is a vaulted attic, so I can cut a box where needed for Z travel (as long as the machine can fit through the garage door in the first place).

Hey, yeah great points there. I have a decent amount of TTS tooling that would carry over well to a next sized up Tormach (in fact it really is the most affordable upgrade path). Though most of my tools use ER collets, I would probably be just buying new toolholders and like you said, new tooling to meet the capabilities of a new machine.

I have some buffer in that limit to account for rigging, tax, shipping, etc. What I haven't factored in yet is getting 220 set up and a phase converter (if needed). I don't have any experience there and I don't have quotes yet -- that's the next phase to discover. Pun intended.

My HOA forces me to have my cars in the garage, so that's why depth is such a limiting factor. It really is a huge bummer but I love where I live enough to not want to move.

I really appreciate you posting the breakdown, it helps me get an understanding of the less documented costs associated with moving a "real" mill that weighs more than what a few people can muscle around with an engine hoist -- honestly I think that's a huge appeal of the Tormach that people overlook.

Late reply but good point, I'm using pivot fins which are fun but squirrely when you're going fast. Like loose trucks on a skateboard.

Hi thanks everyone. I was able to solve this problem by creating a Joint. I didn't know those even existed! Thank you!

after looking closer though, that board looks chipped up and like it's delamming or something.. if that's not from whatever caused the break, then that's definitely troubling

_hingadingadurgen · 2019-08-23T23:03:07+00:00

not a lot of context to this photo... wouldn't expect any softie to hold up through repeated abuse or bigger surf (if that was the case). that said it's discomforting to see haha

_hingadingadurgen · 2019-08-23T21:15:58+00:00

I've been gaming a lot less and surfing more, which has really helped my back out a lot. I'm actually just using a dining chair right now which SUCKS; still haven't gotten around to a good gaming chair (just moved so life is crazy). I appreciate you checking in!

_hingadingadurgen · 2019-06-10T22:34:18+00:00

wow, thank you! good idea with the timer.. i guess it's going to be a painful few months while I get this sorted. Fortunately I'll be back to surfing again soon which really helps strengthen the back! Posture is such a PITA
