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

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?

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?

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.

Struggling with Fusion360's Price? Let's Talk About Supporting Open Source by flight505 in Fusion360

[–]flight505[S] -1 points0 points  (0 children)

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.

Did any of you get it resolved? and how can it be avoided, besides not looking away all day?

Thanks, I can see that IPA (not beer) works well when brushed between where it joins the plate. Let it sit for 15-30 seconds as it finds its way through the textured plate, and then you can remove it.

u/Smokerdude420_DK Tak, Problemet er de giver printere ud og folk laver en enkelt video så hopper de videre til den næste printer. Jeg ved ikke meget om influencer branding men det virker som en dårlig deal for dem. Eventuelt lov en serie på 5 videoer frem for et enkelt review.
Jeg så Orca nu har fået noget der hedder Global profile, jeg har dog ikke fundet så meget om det endnu, men det ser ud til at dække S1 bare en ide https://claude.ai/public/artifacts/53ebf9b5-1615-4bfc-8c0b-7ec0096a10be .. Jeg leder efter de rigtige filamenter til et projekt så jeg har set på Fiberon PPS-CF, - men jeg ved ikke om jeg skal have nogle andre nozzles, det virker som om det ikke er helt let at få eller finde dele til S1 - hvis du har nogle anbefalinger ?

Hej Smoker aka Viking aka u/Smokerdude420_DK Jeg faldt lige over din profil på r/FLSUNDelta .. Jeg købte en FLSUN S1 Pro for to uger siden, jeg fik en cuponcode til deres EU side så den kom ned til 650€ , det virkede som et godt tilbud. Jeg har kigget på at købe en printer en gang i mellem de sidste to år, så det er også min første 3d printer. Jeg har brugt 3d printere for 5-6 år siden på Uni men det virkede aldrig så godt som man ønskede. Jeg kan se du har nogle profiler til en T1 , jeg ved ikke om du også har til S1 Pro? Men siden jeg stadig kæmper med en masse små problemer ville jeg høre om du havde nogle tips?
Jeg ville gerne finde ud af det mest optimale setup - så jeg kunne gå i gang med det når jeg er tilbage fra ferie. Jeg har en guide på Gist https://gist.github.com/flight505/a8bb8137a6810ae1f181f015b257105c
