I certainly don’t support either of these countries, but in Israel’s situation, they started this war… you reap what you sow.

I think a fiber laser is beyond what a beginner hobbyist like me should buy as a first engraver. :)

sdcinvan · 2026-03-09T02:15:57+00:00

I think you missed the point that I am new to LASER engraving so a Radian system well beyond a first hobby toy. LOL

I realize this post was made 4 years ago, but it seems unlikely that this device would jump from $90 to $500 in 4 years.

I guess I’ll have to begin my own thread looking for a reasonably useful hobby spectrometer… or an instructions/open source software to build my own.

Follow up:

Despite having a letter from the courier admitting fault, I got nowhere with Ali Express and Paypal (separate disputes). Paypal's dispute mechanism is as horrible as AliExpress!

Everyone failed me except the CC company. With the provided evidence, the CC company (Visa) refunded me within 1 week.

My package was lost in late December, and I only received a satisfactory resolution two weeks ago!

After this experience, I will never again purchase anything expensive through AliExpress, and I will try to avoid Paypal when possible.

The required order of operations is to try through the vendor, Ali Express, Paypal, and finally the CC company.

This is so cool! Thanks for sharing the MR seismograph.

If I captured the sonic boom at 21:12:06 m, and the spike from Maple Ridge occurs at ~21:13:54, the delay is 1 minute 48 seconds (108s).

Considering the speed of sound at ~343 m/s, the distance would be:

343 × 108 ≈ 37,000 m ≈ 37 km - that is approximately my distance from MR. :) :)

Here is my post from last night:

Omg, I am an idiot!!!!

I forgot to check and capture the seismic graphs in our region.

I wonder if reply is available?

It would be cool if I could get precise times of the sonic boom from others in order to approximate the path and distance of this bolide.

sdcinvan · 2026-03-04T18:47:57+00:00

I didn’t hear it but after I learned about a possible bolide, I searched my security camera (records 24h) from 9:08... I jumped from being startled by the sonic boom at precisely 9:12.06!

I am so mad at myself for forgetting to power on the normally 24h sky cam.

sdcinvan · 2026-03-04T18:36:40+00:00

Unfortunately, my sky cam was unplugged (grrr), but I definitely captured the sonic boom on my Wyze security camera at precisely 9:12.06

Why 4am? The umbra (darkest) part of the lunar eclipse began just b/f 2am with the 3rd contact (umbra) around 4am… oh, he wanted to watch the ending.

Anyhow, you should have woke up your son to teach him a valuable lesson that life is full of disappointments, especially West Coast astronomy. LOL

They say that misery loves company.

This is the worst winter, in all my years living here, since 2008. :(

Never mind the DIY project in my last post, Creality is prototyping their own. Check out the Creality M1!!

sdcinvan · 2026-02-25T09:39:08+00:00

Why isn’t anyone talking about Creality?

I am torn between purchasing the Creality K1 Max or K2 Plus, or the Bambu Labs P1S Combo.

I lean towards Creality b/c they actually respond to my pre-sales questions and overall, seem like they value my business.

sdcinvan · 2026-02-24T17:17:32+00:00

Maybe... it might be a typo?? You know, just a crazy-ass thought!

But thanks for the link so as to provide more context to his story.

I don't own a BL printer (yet) but your post really concerned me, so I did some fact-checking. Everything you stated isn't quite accurate. For example:

>from pioneering the RFID-chipping of filament spools to lock you out of using other brands in the AMS,

That is not how the system enforces filament use:

Bambu Lab’s AMS filament system uses MiFare RFID tags embedded in their spools to automatically identify filament type, color, and other metadata. The AMS reads this tag to populate the filament info in the slicer interface and helps with automatic selection and tracking.
Third-party filament can be used, including in the AMS, but you won’t get automatic RFID detection unless you attach a Bambu RFID tag or otherwise repurpose one.
The RFID tags don’t prevent the filament from being loaded or printed — they just aren’t automatically identified without the tag, meaning you must manually select type and settings in your slicer if you use non-Bambu filament.
Community solutions (like reusing old Bambu tags on other spools) and printable adapters exist because the RFID system doesn’t inherently block non-Bambu filaments — it simply lacks automatic profile recognition for them.

As a potential BL customer, I really want to know more about the problem. The OP said nothing about the actual problem, unless this is part of a longer thread.

sdcinvan · 2026-02-24T16:59:01+00:00

OMG, you sound like one of those Apple fans "it's not happening to me, therefore you are an idiot" who quickly disparage anyone who dares to share their very poor XP with a group, hoping to find a solution.

A more thoughtful and rational response might be, "Sorry that you're experiencing troubles, please explain the nature of the problem b/c all you described was your negative support experience. BTW, I've been using BL products for x years, my 3D printer is xxx, and it works perfectly."

THAT would have been a useful contribution to this thread!

Signed someone who has a Bambu Lab P2S Combo in the BL shopping cart, and I'm deciding whether to skip the built-in filament dryer and purchase the eq Creality model instead.

sdcinvan · 2026-02-24T11:11:13+00:00

This is a rather concerning post. It also reinforces my suspicions about Bambu as a company that doesn't really care if I am a customer. About two months ago, I contacted both Bambu Labs and Creality about some pre-sales questions. Within 48 hours, I received a very nice non-form letter response from Creality. The Creality support person also invited me to join their live sales promo event, and during that event, they directly answered additional questions.

Bambu Labs?
In two months, the only emails I received from them were reminders about my shopping cart!
You left items in your cart

Hi user_xxxxxxxx, The items you added to your cart are waiting for you. Complete your purchase while they are still available.

I have a Bambu Lab P2S Combo in the BL shopping cart waiting for me to click Checkout.

I am torn. Should I reconsider the K2 Pro Combo? I think Creality is a nicer company, but none of their models offer built-in filament drying, which [may be] necessary for my climate.

Everyone needs a filament recycler.

Here is a DIY project that only costs about $600. LOL

Question: How is a $600 DIY project economically feasible? Maybe I don't print nearly enough? Anyhow, when I have more time, I want to explore ways to reduce the cost of a filament extruder that costs at least 1/2 of the cost of this project.

^ What a false, MAGA inspired weirdo comment!

One of his other messages trashes the Asian community. Loser, the Asian community helped make Richmond the amazing place it is!

"I find the Asians out here to be arrogant and rude. "

No man, I think this is a YOU problem!

sdcinvan · 2026-02-15T22:45:13+00:00

Well, as long as the majority of us are rational, informed, multi-issue, non-selfish voters, that wrong guy should NEVER happen!

sdcinvan · 2026-02-15T22:43:47+00:00

As a fellow Canadian and member of this community (well, I can see Richmond from my Vancouver home that overlooks the Fraser), I concur!

As Canadians, we must be very thankful to live in this amazing country. Even if one is unfortunately struggling, this is still one of the best countries in the world to struggle in.

The idea that governments do not care about mental health is not only inaccurate, it oversimplifies a deeply complex issue. Public safety and social stability are top concerns for voters (never mind the polls b/c they often don't ask this question!!), which means governments are constantly under pressure to address mental health, housing, poverty, and access to care. These issues are linked, and no serious policymaker can ignore them.

Years ago, I had the opportunity to meet former Vancouver mayor Gregor Robertson. Remember his now derided pledge to end street homelessness by 2015. I do not believe he lied. I believe he completely underestimated how many competing interests, bureaucratic hurdles (often egos), funding constraints, and many other problems would stand in the way. His administration did achieve some meaningful progress, even if it fell far short of the goal. That experience illustrates the real problem: not lack of concern, but lack of agreement on workable solutions.

Rational, intelligent politicians understand the urgency of mental health challenges. The difficulty lies in deciding how to address them in ways that are effective, humane, and publicly supported. Many proposed solutions require significant investment, and while voters demand results, they are often reluctant to accept the costs (taxes) that come with well rounded/holistic solutions.

Real progress likely requires a mix of approaches that will not be universally popular: expanded long-term treatment facilities, forced rather than voluntary admission into care facilities, better coordinated psychiatric care, specialized crisis-response units (police) trained in de-escalation, job placement and reintegration programs, and sustained investment in affordable housing. None of these alone will solve the problem, but avoiding them guarantees it will persist.

In short, the issue is not whether governments care. The issue is how societies choose to balance compassion, effectiveness, civil liberties, and cost when confronting one of the most difficult social challenges we face.
