I am not sure but there are two things I can think of:

- cura does not do partial line widths for the perimeters (a la Arachne) and your new quantity of walls makes it so that it's no longer evenly divisible.
- your extrusion/flow multiplier has always been off for your filament and you're amplifying it significantly because of the wall increase.

Arachne was developed by Ultimaker for Cura. It's been in there since 2021.

I’ve been printed some of the Hex3D knitted Pokémon for the kids and implemented these gcode settings on my bambu to reduce waste:

https://makerworld.com/en/models/91241

They work so well. Print time reduced by ~30% on models with numerous color changes and waste is less than half what it was before. With purging into infill or a purge model, there’s almost no poop coming out of my printer. Hopefully bambu will incorporate the retraction settings into bambu studio by default in the future.

I'm curious, what dimension-critical thing are you making in FDM?

I model lots of holes for metal reinforcement or attachment pieces to fit snugly into my prints. I have just always dealt with holes being smaller as you describe. It's been my experience that it's consistent enough for me to just model holes the correct amount oversized to solve the issue. When possible, just using a drill bit to clean up a slightly undersize hole produces a better result, especially when the hole is horizontal.

It would be entirely possible to tune this out in slicer settings, probably, but it is 0 effort to remember the fudge factor when setting hole diameters vs the potential weekend project smashing my face into calibration cubes chasing perfection. How to proceed is down to how much your hobby is printing vs printers, in my opinion

It's a clip to replace a broken one on one of those "slide out of a cabinet" garbage can deals. By that nature it has two pretty critical parts in terms of tolerances: The hook portion that holds onto a vertical bar for stability as part of a crossbar, and the bore hole that the actual crossbar sits in. Weirdly enough the hook portion has been pretty rock solid once I sorted out how to CAD a bit better.

The bore hole has been the problem child, but I was able to fix it by kicking down the wall layers to the default 3. Per my calipers a spec of a hole with a diameter of 6mm kicks out at 5.56mm diameter at the default 3. So a half mm wasn't helping; I'll have to reprint at 4 walls to see how much variance I'm looking at there. To your point it may just be a matter of getting more familiar with my printer's resolution and so on and accounting for it in the print designs. This will likely be as precise a print as I need to make for a while since it's a brown field retrofit affair.

While I hate that Onshape is browser based it does make sharing pretty easy. Anyone so inclined can go take a gander here: https://cad.onshape.com/documents/b8c6e404244bb6a8b22120be/w/a0a903f87eef89127b17ffec/e/af46d5aee1bff988b0dc0a85

No, I do not fully understand why I can round some edges and not others. It's on the list to sort out.

I can think of a few options, between them:
- drill the hole
- add compliance to the hole: https://youtu.be/Bd7Yyn61XWQ

That being said, 0.5mm is waaay off.

Been using this the last couple days and it’s definitely a big reduction in purge waste. I was led to it through a video on YT.

For those interested: this adds a 20mm retraction prior to cutting the old filament on every filament change. What this does is reduce the filament left in the hotend that has to be purged out. With no other calibration I dropped my flushing volume down to .5 and my color changes are as clean as ever. I really should see if I can optimize further.

People have expressed concerns about this increasing likelihood of clogging as you are pulling some melted filament out of the melt zone but I haven’t seen it in 40+ hours of AMS printing.

From a cursory reading, I seriously doubt it, it would mean that the filament is melted in the cold zone of the hotend, you have bigger problems than clogging the AMS if that's the case. The only issue could be that you're stretching the filament a tiny bit, but that gets solved when it gets purged back out next time it's used.

What happened here? Did it just come off the bed late in the print?

If so, how do I improve bed adhesion? I have a textured PEI plate at 55 degrees. Higher? Lower?

man I'm stuck on what to do with listing minis on etsy. Pretty much all the real huge mini seller stores list stuff individually, so say artisan guild releases 12 archers. They'll split them all up, do 12 listings, and each one is its own ~9 buck item. Looks clean. I take those 12, put them in one listing, with a picture of 6 at once, with 12 variations, one for each model, and then a 6 and 12 pack.

I feel listing like that its harder to see the individual model you're buying, and im sure lots of people skip over because they want an elf archer, see my picture that has 6 small elf archers in it that are hard to see detail, then see the next pic that just has one dope looking elf archer nice and big, and click that one.

aaa what to do

yeah, im considering that or breaking the 6/12 pack into its own thing, and doing both, 12 individual, then a separate discount listing for buying bulk.

i just like how clean this looks in one of the other etsy stores, shows off the minis way better:

To me that sounds like a good approach. This bit sounds interesting as well, depending on what those APIs allow:

I think the only thing that’s a little weird about it is they seemed to imply that you must chose at this new firmware whether to stay bambu or go open source. So once you upgrade to any firmware beyond that, never can you go open source.

I don’t really have a big problem with it, but assuming that’s correct, I think anyone at any time should be able to decide to switch. Maybe my warranty expires and I want to go open source then.

No, to me it says that even from later Bambu firmware you can switch to ”R” which is similar to 1.07.00.

And in future you may also be able to jump back to newer Bambu firmware from ”R”, but once the ”R” is installed the first time you’ve forfeited the right to warranty and official support.

From the jailbroken ”1.07.00 R” you can then upgrade any newer jailbroken firmware, like the 1.07.01 based X1plus.

I think it’s not clear at best. This would require bambu to allow you to downgrade your printer at any time, which is the entire reason they don’t want to just allow it. They want to fix security holes.

If you continue with bambu and let’s say install some future 3.1.1 firmware. You’ll need to downgrade to 1.1.7, and then go open source.

Maybe it will work that way, but if they aren’t supporting any development of you coming back from a third party firmware, I find it dubious they would support letting you go to it.

Managing that software to downgrade safely after future hardware and software revisions would be cumbersome.

Couldn't they just allow the printer to flash any firmware and store a version changelog somewhere in the onboard system memory that the bootloader has access to as a way to track it on the machine itself?

Some sort of non-volatile storage that just stores date and firmware version data?

I know that could still be spoofed if someone is dedicated enough but most people aren't willing to go to that :effort: maybe?

I want to say DaVinci printers did something like that but can't remember specifics.

If I were a developer on their team, I wouldn’t allow it. It’s allowing people to root the device and they’ve explicitly said in new firmware they do not want to allow that.

Security is hard enough to do where there are no holes. Forget about very small controlled holes.

Top 2 are what I sent to my P1S from handy.

Bottom 4 are results of my second (and better) attempt, printing at 50% speed. I tried it at 100% the first time and got similar issues, only they were slightly more pronounced. I hoped slowing the speed would help, but it only did a little bit. Any ideas on what I can do to remedy this? Using polymaker PLA currently. Do I need to use a slicer+ computer to fix problems like these? I haven't sliced anything yet that I've sent to this printer, only sent things directly from handy to the printer.

This aside, I still really love this printer.

As someone that recently started this: Don't.

The kinds of things I want to print come out just as well (if more slowly) on my FDM machines and I don't have to PPE up to play with them.

Once I use up the rest of my sample resin I'm going to pack the printer up, set the wash tank in the sun and let the alcohol evaporate, and put the whole mess away in the shed once it's safe to do so.

The FEP/PFA film hassle alone puts me off.

Printed three things and the 4th thing stuck to the film and can't be removed without possibly ripping the film, so the film needs replacing and I just don't want to deal with the hassle at this point.

My Prusas have spoiled me.
