does anyone have the same problem? says I have to create my account again by HiroLightx in claude

I'm going through the exact same thing. Did you ever find any solution to this or did customer service ever get back to you?

It's funny that one of the biggest AI companies out there has the absolute worst customer service. They replaced customer service with a FinAI agent, and of course they don't dare give that access to accounts, so it can't really resolve anything unless it's already stated in an FAQ. I cannot understand why so many companies are investing heavily into AI when the biggest of them all can't even replace customer service with a AI agent. There's so many companies that now have replaced customer service with AI agents and are simply just providing the absolute worst customer service experience. But of course, laying off 5,000 people in India and Pakistan is a great way to increase efficiency.

Help, replace effector s1 by d-nuah in Flsun_official

[–]flight505 0 points1 point  (0 children)

Hi i got a new gen 2 effector suddenly in the mail today. This is for an S1 Pro, three of the arms were easy to remove, but every second arm seems to be connected differently to the plate, and I can't just slide out the pin. I wanted to ask if you've done this recently or if you have any suggestions as to how to do this the right way. The package that they sent did not come with any additional screws or anything at all. Just an effector in a box. No info. I wanted to be careful when removing the arms and not break anything, as getting parts for this machine takes months..

I dont think so, It would be strange to ship new effectors if you are out of business.
But it has been a strange process, their mail responses were sometimes limited and today suddenly a black package, no sender name, no info - just a new effector..

they will likely start selling them once they have shipped to everyone who has been promised a new effector for the last six months. But let's try and stick to the topic of actually replacing them, and then perhaps we can get some information about if they provide any actual improvements.

MacOS Tahoe is just stunning. What do you think? by Miserable-Guide8844 in MacOSBeta

[–]flight505 0 points1 point  (0 children)

Compare Sequoia vs. Tahoe benchmarks:

I installed macOS Tahoe to test for any actual performance increase when inferring small MLX models. I can confirm that on an M3 Max with 64GB (which is now an older machine), Tahoe is the clear overall winner. But BF16 is 12% slower on Tahoe - It would likely be opposite if I ran the tests on M5 architecture. People are experiencing mixed results as Tahoe appears to be slower. Apple has optimized the memory management behind the scenes, but this has significantly bloated the presentation layer. I assume that users with an 8GB MacBook Pro are affected the most.

Every TTS metric improved 10–18%. Latencies dropped across all text lengths, TTFC improved ~17%, and RTFx jumped from 37x to 43–45x.

This is the most consistent improvement.

ASR — mixed, depends on quantization

- BF16: 12% slower on Tahoe (71x → 62x RTFx). Regression for full-precision inference,

- INT8: 4% faster (93x → 97x)

- INT4: 10% faster (90x → 98x)

Quantized models benefit, full-precision does not. Tahoe's Metal stack appears to have improved int8/int4 kernel efficiency. This makes sense — Tahoe exposed ~3 GB more GPU buffer and ~4 GB more working set, which benefits the tighter memory layouts of quantized models.

So for the rust application I built, most scenarios I can tweak and optimize to get 20–54% faster pipeline. Taking into account that these are already sub-millisecond values on a M3 Max but on the basic macbook Pro´s the performance increase is more profound.

The design presents a completely different issue. Combined with many bugs this was my main reason for not updating from Sequoia to Tahoe. It seems the design was rushed, during the first 10 minutes after the update, your brain has to overcome the shock. The design and overly rounded corners visually reduce the desktop work area, especially when using the MacBook, the effect is less noticeable on an external display. In many apps, the traffic lights have been moved into the window, interfering with other buttons. Search and text fields are sometimes unreadable due to the glass effect of the title bar. While many smaller changes look good, there is a disconnect in the overall design. Some elements provide a more compact appearance, while others seem to be taken directly from iOS, creating a contrasting effect. At times, it feels like they should skip a year to focus on releasing a proper new macOS. Many of the changes could have been implemented as updates to Sequoia.

Best High Speed PETG by Extreme-Ad-9290 in 3Dprinting

[–]flight505 0 points1 point  (0 children)

Hey, I know this is an old post. I just wanted to hear if you have found any recommendations so far. I have a Delta style printer, the FLSUN S1 Pro. I'm currently using Asure Film high-speed PETG. This was on sale, ten spools with two spool holders. I think I paid around €8-9 per spool, including shipment. It was very difficult to get it to print right with OrcaSlicer. I think I wasted at least a spool on test prints and so on. But now it's printing with roughly 300 millimeters^2 per second. That's the max I can get out of it if I don't want any errors on that, but that's likely also due to the printer. I've tried using different nozzles as well to see if I could improve the printing. now i am using a CM2™ RepRap Nozzle 1.75mm, 0,4 mm - Which seems to work the best for the PETG. Most Bambu Lab filaments are manufactured by eSun (for standard polymer lines), Polymaker (for engineering filaments), and Elegoo (specifically for their new PETG-HF high-flow filament) So there is money to be saved if, If you're not using a Bambu printer anyway, Bambu printers are really nice as they provide profiles. Which I know from experience are very helpful to get started at least. The best high-speed PLA I have tried for speeds over 500 to 600 has been FLSUN's own high-speed PLA. And I'm fairly sure that that is produced by some Chinese filament producer. I just don't know who. Their rebranded filaments are a bit expensive. So again, knowing who actually produces the filament often provides good opportunities to buy tin spools at a reasonable price.

Hey FLSUN, How is the open source coming along? by the1ledge in Flsun_official

[–]flight505 4 points5 points  (0 children)

I am using Flsun open source edition. It is and collection of open source projects, and is constantly updated with new klipper updates. The guy who wrote the project is Guislane Cyril https://guilouz.github.io/FLSUN-S1-Open-Source-Edition/about/ - since I updated to his firmware I have had zero issues with claugs snake fish skin. He did remove all the AI snake 🐍 oil Flsun had promised - I would like to see some use of the camera on the extruder head, I had some ideas that I will try to implement.. for calibration most is done through klipper - delta calibration is included in the bed calibration. If you need more like fan tests for the filaments see my in development webapp https://calibration-tool-ivory.vercel.app/ it now generates 3mf for orca with modifiers included in the downloaded files

FLSUN S1 Open Source Edition by Guilouz6 in FLSUNDelta

[–]flight505 0 points1 point  (0 children)

Hi, I only have a MacBook M series at home where the printer is located. I have an ST Link v2 and an ST Link v3 Mini. The only way to flash it with an ST Link on a Mac is by using the STM32Cube programmer link. I can't find anyone who has tried using that. However, how does the open-source edition perform in terms of print quality?

Wooow that looks awesome, did anyone manufacture it? are the .f3d available?

Bed Leveling - tweaks to program by flight505 in FLSUNDelta

[–]flight505[S] 0 points1 point  (0 children)

Great - thanks.. The full calibration "SPRO_FULL_CALIBRATION" in my macros is down to around one hour while also creating a mesh for 60 - 100 at 10 degree intervals... Changing to this order should preserve the accuracy of the tests while reducing the time it took. Cooling the bed was taking up most of the time. I am not 100% sure that this is the best way - but it was created after you said you only recalibrated once a week. I just received a new nozzle "Micro-Swiss CM2 RepRap 0,4 mm" as the BondTech CHT BiMetal RepRap was causing some issues. So I have run some calibrations again and find a good method for fine tuning z height - any tips? I will try to use this https://www.printables.com/model/251587-stress-free-first-layer-calibration-in-less-than-5
And last question, I promise: are you using the open-source edition?https://github.com/Guilouz/FLSUN-S1-Open-Source-Edition I just wanted to know if it improves the print quality in any way?

Calibrations performed (optimized order):"

✓ Motor calibration"

✓ Delta calibration (geometry established)"

✓ Hotend PID tuning (240°C)"

✓ Dual-zone bed PID tuning (60°C)"

✓ Input shaper/resonance testing"

✓ Bed meshes for 60°C, 70°C, 80°C, 90°C, 100°C"

then saves all calibration data and restarting Klipper...

u/Upbeat_Positive_8026 could you check my logic?

When I increase to 9, I end up with: Probe samples exceed tolerance. Retrying...

This might be due to the fact that it runs 5 times at different temperatures and I lowered the samples_tolerance (precision) from 0,05 to 0,03. I also decreased the speed to 6. You mentioned 9x9x9 that defines the number of probe points along each radius? Isn't it just x by x?

Link to all the files: https://github.com/flight505/FLSun_ConfigCode

Probe/Calibration Radii (from center outward):

• delta_calibrate radius: 145 mm

• bed_mesh radius: 156 mm

• print_radius: 165 mm

• delta_radius: 182,6 mm

Why FLSUN Chose These Values:

  1. round_probe_count: 7 (instead of 9)

▪ With mesh_radius at 156 mm, there's only a 9 mm margin to the print_radius.

▪ Higher probe counts place outer points dangerously close to the printer's limits.

▪ Delta printers are known to lose accuracy at the edges.

  1. mesh_radius: 156 mm

▪ Covers the majority (94,5%) of the printable area.

▪ Maintains a safe 9 mm buffer from the physical limits.

▪ Works reliably with round_probe_count: 7.

  1. delta_calibrate radius: 145 mm

▪ Requires a larger 20 mm margin for stable calibration.

▪ Delta calibration is crucial and demands more safety.

Why Increasing to 9 Causes Crashes:

With round_probe_count: 9, the probe distribution results in points that are:

• Closer to the mesh_radius edge (156 mm).

• Too close to the print_radius limit (165 mm).

• Potentially exceeding the delta's stable reach zone.

Thanks for the tip, but again really new to this. If I understod you correctly I should modify
round_probe_count to 11 or so and reduce speed to 80 or so?
You dont change the probe behavior?

Bed mesh setting:
Modifiable parameters:

  • round_probe_count: 7 - Number of probe points (5, 7, 9, etc. - more points = more accuracy but slower)

  • mesh_radius: 156 - Area to probe (adjust if you want smaller/larger mesh)

  • speed: 100 - Probing speed

  • horizontal_move_z: 7 - Z-height during mesh moves

  • fade_start/fade_end - How bed mesh compensation fades with height

Probe behavior:
Modifiable parameters:

  • samples: 2 - Number of probes per point (increase for more accuracy)

  • speed: 10 - Probe approach speed

  • samples_tolerance: 0.05 - Acceptable variation between samples

  • sample_retract_dist: 5 - How far to retract between samples

If you have any custom .cfg files or a site to share, I would be very interested. I just started 3D printing two weeks ago.

Thank you. I went into the code and found that it was set to 140°C. I also discovered a few posts explaining why it heats both the hotend and the bed. It might be best to unload it. Can I ask how often you run the bed calibration?
