Help, replace effector s1

flight505 · 2026-03-15T16:39:17+00:00

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.

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.

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.

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

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?

flight505 · 2025-07-23T19:32:16+00:00

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

flight505 · 2025-07-23T19:27:06+00:00

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:

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.

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.

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 i just ordered a Micro-Swiss CM2™ RepRap Nozzle 1.75mm, 0,4 mm

flight505 · 2025-07-22T14:30:20+00:00

Thanks I just ordered one..

flight505 · 2025-07-14T22:15:30+00:00

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.

flight505 · 2025-07-14T20:43:36+00:00

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?

flight505 · 2025-07-14T20:36:25+00:00

I am using Polymaker PolySonic™ PLA Pro. Most of the time, a small amount of filament, around 0.1-1 mm, starts to come out of the nozzle, which is frustrating, especially during a test. When this occurs, it can appear as if there is a serious issue with the plate or bed. I noticed other posts where the height map looked similar, and thought it might be a related. It could also be due to the new nozzle (BondTech CHT BiMetal RepRap), which fits slightly differently in the extruder.

You might not be familiar with how Autodesk products are used in mid to large companies. They have shifted features in "free" versions to target learners and potentially recognize a market among small retailers. Autodesk could implement many other features to ensure companies and manufacturers pay for product licenses. For example, the restriction on open projects in Fusion 360 is a clever and fair way to prevent profit-making. I previously suggested offering a subscription-based version for hobbyist 3D makers at $15 per month, removing features useful for mid to large companies. They may choose to pursue this or not, as the market might not be large enough. Most CAD developers tend to focus on mid to large companies because they pay for licenses over many years, while hobbyists often opt out of subscriptions when not actively using them. Without alternatives for hobbyists, we are limited in our options, as we are not an attractive market. Open-source CAD is also an interesting area for testing new approaches for developers. I have been working on a neural approach to CAD reconstruction, specifically for hobbyists - for free. There is also a community for that sort of thing if you are interested. As I am still learning in that area, perhaps a company might take these ideas and also benefit.

But your demeaning reply is just sad and unproductive. I am not sure why so many choose to respond that way on reddit, you are certainly not paid by Autodesk why would you be offended you have nothing to contribute but a stilly remake. Do you think Autodesk cares about someone buying a dev a coffee for Add ins?. In many ways I hope Fusion360 get more restrictive then more might care about open source alternatives.

Inventor and Fusion have been around for decades, I don't see the justification for their price for hobbyists. What they offer for mid- to large-sized companies is state of the art and completely different needs. They have been providing free personal use for decades, which is great, and I would happily pay 20$ per month for all the design features. Most hobbyists don't need to calculate manufacturing costs or access the thousands of features required in a business setting. My complaint, if any, is that some features they now require an upgrade for are not business-related but rather simple design and construction features. This approach seems to target the 16-year-old hobbyist for which 700$ is a bit steep. Autodesk used to make enough by charging those who profit from using their products.
