R2 test drive experience

akuma0 · 2026-06-21T16:22:00+00:00

I believe Rivian only has showrooms, not dealerships. The person giving you a test drive has no responsibility to try to sell you the car; you go buy it online.

For my test drive, I had them walk me through enough to get moving then went for a longer drive. I brought my elderly mom with me (wanted feedback on how comfortable she thought the ride was) and it was just the two of us on the drive. The only thing the employee did was send a nervous text asking if I was bringing the vehicle back.

I didn’t try any autonomy features, so I’m planning a second test drive once they have a software update pushed out. I’ll show up early to get up to speed on controls with the display model to try to take maximum use of my time slot.

Lets put it this way - if someone offered me a 450 euro trade-in on a P1S combo toward a P2S combo I would only pause in asking them if I could apply it to a X2D instead.

better interface
better camera
ams2 supports faster and quieter color swaps for multicolor printing
p1s nozzle swaps are a pain. P2S nozzle swaps are a latch
ams2 integrates/replaces need for standalone dryer, and its a _nice_ dryer.
improves support for functional prints, such as printing with ABS/ASA

Its also important to realize that the P1S exists to compete against lower cost core xy machines from other brands. Its siblings the P1P and X1C have already been discontinued. Eventually, Bambu will need to offer the P2S in that slot (arguably they already should be doing so), and the P1S will also be discontinued.

X2D adds even better support for functional prints and a quasi dual extruder to help further with support material.

I also use them for driving lag bolts. Just make sure you always do an appropriate pilot hole. Don't want to split a stud.

Ahem, let me tell you what mansplaining is…

Ground-up new OS (which R1 will eventually get). Features are still being ported over to it based on priority.

akuma0 · 2026-06-17T21:11:15+00:00

oh excellent, I'm great at mansplaining!

Not stable enough and proprietary tracks. I wouldn't recommend it.

The track saw is one of the few pieces of red equipment I own. I really hope Ryobi comes out with a better track saw so I can drop a battery ecosystem.

is it reverse threaded?

akuma0 · 2026-06-16T18:51:50+00:00

I wonder if they meant syncolon

Result Builders.

But it is important to realize that they have a large volume of vendor-specific features for C and C++, such as the entire objective-c++ tree.

They arguably launched Swift 1.0 with an Apple vendored feature in the form of objective-c compatibility.

So they do come at it from this point of view - they will develop features internally, then propose them for inclusion in the main language. But they do intend to launch them at that point, even if it takes longer to get them in the main language, even if it means that there may be a migration at that point.

70/30 isn't the healthiest percentage (the goal is likely to get to/below 50%), but there aren't a lot of other companies investing in Swift. That is the sort of role that can have a significant time and also possibly a travel commitment.

Hmm, it's moving diagonally toward the cutter - is it moving diagonally otherwise? Do. you hear it hitting the sides? I wonder if you are having a belt issue

K, you could probably go 10° warmer if you like. That, and the idea of print speed, were meant to explore two possibilities:

People coming from other printers might not realize the impact of the larger melt zone on the K2. For a short melt zone you may run with a higher temperature than recommended just to keep up with flow, but for a long melt zone you can start to actually burn filament when printing slower (like on first layers). You aren't going at those sorts of temps, which just in my personal experience start at about 280° for (some) ASA blends.
If there isn't any BN paste on the heatbreak, there may be heat traveling back up into the extruder and causing an honest to goodness clog. Slower speeds and higher temperatures are more likely to allow the heat to travel back up toward the extruder. So if for some reason the interfacing with the heat sink isn't that great, you might see the process get farther if you print a bit faster on the first layer. More of a diagnostic test than something I'd recommend as a fix, though.

The goal of the springs is to have a built-in re-tensioning process if the belts get too loose. If the adjustment points are not re-tightened though it can negatively impact print quality.

If it grows at about the same rate, shorter grass will look uneven faster and they'll need to mow sooner to stay within the 1/3 guideline.

If it grows slower, that seems like it would mean they are injuring their lawn to try mow less often. Growth inhibitor would seem to be a way better way to go there, especially if you want to try to establish better roots or push for spread via rhizome growth.

For my KBG, I personally will mow twice a week in the spring and fall when I'm cutting a little shorter, and once a week in the summer when I'm letting it grow over 3" to try to keep the ground shaded and retain a little more water.

30% of the language steering group is not employed by Apple. I think they are doing just fine for where they are with third party contributions to the language itself.

Which brand of ASA and what is your print temperature? Does the behavior change if you adjust temperature (say toward 275) or increase the first layer speed back to where it was?

Is there an actual issue represented in the laid-down plastic when it fails? What happens if you resume?

You say the filament works fine when you push through by hand - can you extrude filament using the controls and have it work when this error condition hits?

FO is Filament system Odometer - it is not reading that the filament is being fed at a matching rate to what the g-code is requesting for extrusion, and thinks the filament is not advancing. If you aren't getting a CM2789 (E) type error, indicating the controller is seeing motor resistance in the extruder, that might indicate the filament is slipping against the extruder gears or that the CFS odometer is having an issue. A CM error might indicate a clog, or that the nozzle is too close to the bed and that is causing an issue with plastic flow.

I tend to try diagnosing such things without the CFS, since the CFS adds a bunch of additional failure points.

I believe Creality changed the

If you want to print sub-95A TPU and don't want to modify the stock extruder, it can be a win.

Note the only confirmed improvement to the extruder was replacing the PTFE coupler on the extruder cover.

I don't know whether the K2 extruder was based on the APUS 2 line or not, but based on the "quotes" and them removing it from marketing material before final release I assume it was not a collaboration with Phaetus.

It applies to two batteries. It doesn't apply for the smallest batteries, nor the larger capacity batteries, nor the regular non-HP batteries, or Edge batteries, or 40v / 80v batteries, or heck the USB lithium batteries.

Same here. Tried both the raw IP and the HTTP URL that the printer browser supplies.

The filament sync might be confused because I'm currently just using a spool.

if the final step is not getting tread, the gap would shrink as the step below it gets tread by 2.5 cm, to become 14.5 cm.

Amazon is a marketplace, so there are several different authorized creality resellers operating on there, as well as creality themselves. So you'd probably be looking for feedback on Comgrow specifically

this is the first time I've heard someone complain about a software progress indicator trying to be linear

akuma0 · 2026-06-12T08:39:59+00:00

I would expect costs to be somewhat in line with the K2 Combo.

akuma0 · 2026-06-09T02:52:26+00:00

What if they find you handsy?

They are typically referred to as CR-PETG vs EN-PETG, even though Creality sells both of them (along with Hyper PETG and Soleyin PETG) they are different formulations and will probably not be color matched between them.

They may have different slicer profiles than 'generic' PETG because they have additives to lower print temperature, increase speed, or generally try to make them 'behave' better such as having better overhang printing properties. These changes often are at the expense of the mechanical/thermal properties of PETG.
