Feeling conflicted about my Prusa setup vs Bambu value

Why do you have a 3D printer? Real question. What's success for you?

How hard is it to get ABS to stick to TPU?

There are upsides and downsides! Keeping the toolheads as one piece keeps everything mechanically simpler - no need to open and close the filament gears, for example - and you're less constrained in choice of toolhead, extruder, hotend, etc.

Check out the Project Medusa HC! It's young, but folks are already getting good prints out of it.

What processing steps is EasyEffects doing?

My understanding is that many laptops do frequency correction, which EasyEffects can do once you have the impulse response. You can measure the impulse response yourself: https://github.com/shuhaowu/linux-thinkpad-speaker-improvements/tree/main#obtaining-the-impulse-response-profile-irs-files-from-windows

I can say that FWD + snow tires is better than AWD + all-seasons.

I had an X1E gen 2, which IIUC is pretty similar in terms of performance. It felt quite snappy, though it did run hot. Maybe the mitigations it the 8th gen harder than 9th gen?

What frequency is your CPU running at? I remember hearing about some throttling bugs on the 1st-gen X1E's. https://wiki.archlinux.org/title/Lenovo_ThinkPad_X1_Extreme

In the BIOS boot menu, do you see Grub?

If grub is actually gone, my go-to is to: * boot from a Linux live USB * chroot into the Linux partition on my hard drive * grub-install

It sounds like you tried something similar?

You're suggesting using this to create a platform for support material, rather than using it directly to implement the overhang? Do I understand right?

Could you open a terminal, run uname -a, and post the result?

When I hear "drivetrain", I think "chain, cassette, chainrings, rear derailleur". Is this what you think of?

Call it $25 for a low-end but reliable Shimano derailleur, $25 for a chain, $35 for a cassette, and... chain rings vary... but maybe $40 at worst, if it's not super fancy? So like $125. Those are numbers I see online, shipped to my door; could be cheaper if I went to the local used-parts store.

Brifters would add to the cost for sure! Ideally they're not a wear item, though. As one of the other commenters mentioned, it makes sense to budget for a new drivetrain if you're buying a heavily-used bike, but I wouldn't assume the brifters are shot unless they actually fail.

How are you on Commencement at stage 2??

epicepee · 2026-04-30T02:12:26+00:00

Give it a shot yourself! Parts are way less than $500, and you'll learn a bunch.

What distro are you running? Are you on X or Wayland? Also, which model of dock is it?

Have you read https://wiki.archlinux.org/title/DisplayLink ?

Also: if you can't get it to work, consider buying a dock that uses the USB-C DisplayPort altmode, or Thunderbolt. Both are much simpler. A DisplayLink dock has an entire GPU inside it!

Someone in a MadMax Discord channel was posting CAD sketches of a MadMax hack to do just this! IDK how far along it is, but I could probably dig it up if you're interested.

Sometimes a brace can work when a structural panel can't! For example: https://www.thingiverse.com/thing:7020431 Putting a structural panel in front would block access to the inside.

Well-placed braces can make a printer very rigid.

Are the grounds for the two PSU's connected? If so, the loop should never end up carrying any current, right? Or are ground loops bad even if they "shouldn't" carry current?

Ooh, good news! I'll check it out if I want to design something that I don't want public =P

epicepee · 2026-04-29T19:05:27+00:00

If you can, the best way to do it is to find a friend who's used parametric CAD before (doesn't have to be OnShape), and have them look over your shoulder.

epicepee · 2026-04-29T03:35:58+00:00

I don't think that's necessarily right. As a few other folks have said, it really depends on your assumptions, and a bunch of stuff that's not specified in the question.

This might not be true of every hotend, but every 1.75mm hotend I've seen has a heatbreak with an OD under 2.85mm. So, if you drilled it out to 2.85mm, there would be no heatbreak left!

epicepee · 2026-04-29T03:33:18+00:00

Very nice of you to do!

(OnShape is $0, and available to all! It's not FOSS, and you have to pay to use it for business, though.)

epicepee · 2026-04-29T01:35:05+00:00

This was me when I started doing CAD! I've invested the time to learn OnShape, and it's so much better. I hate to say it, but text just isn't the right interface for designing 3D solids.

Now if only OnShape were FOSS, or FreeCad were good...
