[@lasarith2]

If I had to guess, it would seem that you’d need to tune it to slow down for certain parts of the print while retaining the fast print for others - ( take advantage of of the speed while maintaining the fine print control)

[@Veefan3]

[@JakobDam]

It looks very promising. The failing supports are easy to solve in the slicer settings, so FLSun should just do that to their presets. Slower acceleration and jerk for support and a bit lower print speed. But the issue where supports, fail to adhere to the bed especially tree supports, is due to the acceleration and jerk settings.

[@alboroble]

Will you test T1? I have a T1 and have been using it for three weeks , super fast , I don’t know why so many people criticize its 1000mm/s. Why are machines with a default configuration of 250mm/s allowed to advertise 600mm/s, but machines with a default configuration of 600mm/s are not allowed to advertise 1000mm/s? 600mm/s and 1000mm/s are just movement speed, We need to discern whether the true value of the product meets our own needs, instead of just complaining and touting .

[@jonnyroy]

I expect that the "texture" you are experiencing is due to the stepper motors microstepping resolution. Unlike standard x-y-z slignbed or xy-yx-z corexy configurations, deltas are a z-z-z configuration. So the kinematics of the arms' parallelogram create axises that behave as arcs. Hense the carbon fiber 45 degree texture. In other words, the step-drivers need tuning. Try printing a cylinder.

Thank you for posting this! I've been waiting (impatiently haha) since I saw your unboxing! I ordered one at the sale price and I'm hoping it ships soon! I'm glad to know you are getting feedback, back to them. It seems like they hurried to get this out the door ahead of the Prusa HT90 and whatever Bambu comes out with next. A lot of the problems people seem to be having with it are all software - whether it's the slicer or the firmware. I also heard the install of klipper and mainsail on it are old versions too and they haven't unlocked SSH yet either. But with it being so brand new, I can't help but hope that a year from now, this will all be old news? The fact that it's already sold out again I hope is a good sign! Thank you for continuing to use it despite the issues and for sending your feedback to them, I'm sure it's helping!

[@Irek_Poland]

protonus....LOOL FLSUN?

[@ptr.nitsche]

It's incredible how good the Bambu prints look. I got a Flsun SR for myself one year ago and upgraded to a Bambu P1. The print quality, as well as the print profiles, are so much better on the P1. I will never go back

I don't even mind the imperfection on the Solid Snake bust. I think it gives nice texture in this particular case.

[@electronicsandewastescrapp7384]

yeah but imagine you're trying to print something else.. and will never be able to get a decent surface finish. I'd rather go 24 hours vs 12 but have all that effort amount to something I can use. your printer shouldnt be stuck on fuzzy skin.

[@leoenin]

I owned the V400 from FLSUN, and I will try to keep away from any of their products in the future. I’ve had so many issues out of nowhere with the quality. The supports kept failing over and over for no reason. The filament wouldn’t stick to the plate. The leveling procedure was DUMB and didn’t keep the nozzle level even for a couple of small prints (z-offset kept getting off randomly). I’m not even talking about the lack of accuracy, which is a common problem for deltas. Software and support feel like a 'basement factory' amateur. It's a huge headache. No, thank you, I’ll stick to Bambulabs.

[@christiantrab6160]

Yep, same here, gave away the V400 for free, when I got the X1C.

[@1981AdamGs]

Why did they make the spool compartment so small? Seems stupid to make it that tight when there appears to be acres of room on the top of the machine.

Now can you review the t1? The s1 is now $1500 and the t1 is $600 it might get more people to buy it because it is less than half the price and it still goes 1000mm/s

[@flphil4537]

Remember with deltas, the advertised height of build volume is only directly in the middle. Build volume isn’t a perfect cylinder. Its a dome at the top

[@ippaku]

Proud picture of member commenting to Support on the video and the crazy guy that takes his magnetos‘s twin. I’m very glad with the innovation of this printer. I will not be buying it however, I’ll stick with my elgoo & Bambu printers for now. Be well be you.

[@truantray]

I have two FLSun V400s, they run constantly. Between the speed and Klipper web interface I will never go back to Cartesian printers. Prints PETG and NinjaFlex perfectly. I bet the support printing issues are about PrusaSlicer. I can tell you did not do an overhang test, these printers can print to 75 degree overhang.

[@meadmaker4525]

So, slow the print speed to something more normal and use Orca Slicer and I'm guessing it would be maybe 75% better, just with doing those things. And FLSUN supposedly just released a big firmware update to correct a bunch of issues with this printer, so it would be interesting to see a follow up video on how those changes may (or may not) have improved this machine. The issue with the profiles sounds like FLSUN is playing catch-up and maybe fielded the product too soon. I'm hoping they'll just ditch their slicer and develop solid profiles for Orca for everybody to use. If they could dial-in this thing to X1C-level user experience and print quality, I'd order one ASAP. I just love the delta design. I don't care so much about the speed, especially since it seems to come at the expense of quality. Better to take a little longer and have a nice result than to go really fast and have the result look like garbage...or fail altogether.

[@VuMai17]

hey uncle Jessy, my process for loading filament is to push the filament till it stops, then put the roll on the holder. the hardware is very good, but the firmware, software wise needs more fine tuning. the S1 needs a 0.6mm nozzle profile!

[@brendandawes9227]

I wonder if the weird texture is due to vibration at the higher speed? Maybe they need some kind of damper base/pad if it can't compensate enough for it. Bambu has the feet, just a theory

[@inmansfault592]

I don't own a 3d printer (yet,) but own multiple laser engravers. Don't know if this could apply to 3d printers, but is worth mentioning. I was getting strange lines in my engravings across all my machines, so I knew it couldn't be a calibration or mechanical issue. After much toiling and gnashing of teeth, i realized it was the shitty/old wiring in my shop. I ended up having to put my lasers behind battery backups to smooth out the power they were getting and weird lines went away.

[@oyuyuy]

[@Volvoamazon62]

I have the V400 and due to the Delta setup (I think), the supports are knocked over much easier than on a cartesian printer. That's also why you need to use Gyroid infill, otherwise it scrapes..

[@patrickpat2161]

I got 12 v400s and yea. Supports need to be thicker and the nozzle it comes with is trash and can cause the supports to print poorly

[@damiencross7334]

I have a v400 and its fine. Its better than my neptune 4 plus but worse than my bambu p1s. Definitely have to use gyroid infill. Only one that worked for me. The print quality is decent and it has good speed. I wouldn't drop a grand on this tho. Been doing a lot more resin printing these days. For me you can't beat bambu right now.

[@Shaerky]

Does need alot of work however i 1000% do see the day were we are able to print out helmets sub 8 hours. Technology is only getting better, the community is only growing more and weve already come so so far in just the last few years alone

absolute beast, its good to see a more industrial printer at an affordable price. lets face it this is no desktop machine, no one wants to work next to one of these at full speed. you need a spare room at the other end of your house or a garage to put this thing in. it has it's place though and ill probably buy one. 🙂

This is only a temporary issue. The printer just came out, and it's already sold out. They sell parts for all their other printers on their website. I would imagine parts will be available for this model within a few weeks as they build their stock of components back up.

[@peterle987]

3 rods will always give "3-dimensional" effects to layer lines - so it will produce an individual texture by concept.

[@GonnerMeLeggies]

I have a feeling that your support failure may have been from the pressure from the CPAP fan not working well with the tree supports since it creates a hollow tube

[@eyeliketony]

Looks like it needs some refinemnt before considering purchasing.The noise levels seems to be the biggest negative factor to me. The rest can be resolved with future firmware and slicer tweaks.

[@PaulDominguez]

They need to make a printer profile for Orca slicer

[@Wow_Trains]

In my opinion I expect to see the S1 start off pretty rough. It is going to take Flsun or the community a while to really refine the slicer settings for this printer. A similar thing happened with the v400, their original firmware for it had some issues and had big issues on the dimensional accuracy. The latest firmware, which took almost a year fixed all the issues. Again my experience and my opinion

[@ValTek_Armory]

the surface finish is inexcusable for such an expensive machine in today's market

[@theElemDragon]

100% this. Coming from Ender printers (Ender 3 Pro, then Ender 3 S1 Pro) to a Bambu P1P (and not long after an X1C), while yes, the printing speed compared to ANYTHING the Ender's could provide was fantastic, but it was the quality without a lot of tinkering that sold me on them. I'd rather wait several more hours for a great quality usable print than a decent quality print that you might want to try to print again. Now we just need a larger format Bambu printer to come out sometime soon, and I'll be even happier.

[@thedylpickle5909]

i like fast printers

[@SANSd20]

And I cannot lie.

[@Wren6991]

If the acceleration tops out at 4g (40000 mm/s^2) then you hit diminishing returns on print speed at around 300-350 mm/s. Saying it does 1200 mm/s is an EXTREME stretch.

[@trinodot8112]

Im not a 3D printing expert, but I bet the weird texture is ringing and just looks different because it doesnt have linear kinematics like a regular printer. I modded my voron to print at 100k accels, but I limit the external perimeter acceleration to 5k to avoid this issue. It prints blazingly fast and still has steller exterior quality

[@raiden72]

14:05 You need to reserve the printer's IP in your routers DHCP server lease reservations page..... Otherwise the DHCP lease will expire and your printer will get handed out a new IP every 24 hours or 1 week or whatever... You should do this from a top-down perspective and not from the bottom of perspective (of reserving the IP on the printer)

[@cerrkprgragg]

@@petercallison5765 I mean flsun continues to innovate in high-speed printing. You can take a look at what anycubic has done. In addition to plagiarism, it is still plagiarism.

[@sabahoudini]

The problem with that printer is that the arms are attached to the bottom of the toolhead making it (toolhead) top heavy. When it changes direction the toolhead will want to "nod" in the direction it was previously going. If you attach the arms to the toolheads balancing point it would not do that. It should be somewhere at 70% from the bottom since the extruder motor is up top I'm assuming. If it's bowden it should be a bit lower. Fixing this would improve print quality immensly. You can see evidence of this by printing the top layers with fast speeds and accels. They will not look very good, meanwhile if the toolhead is balanced and everything is stiff you should not be able to see which was the top layer and which was the bottom layer. I saw the Prusa delta printer and it looks much better as the motor is very low down and also the toolhead is not as tall.

I enjoy your reviews. As an owner of the FLSUN V400 delta, this machine doesn't feel like an upgrade. Maybe it's faster, but it's noisier and its got a proprietary printhead.

micronics review when?

[@RocktCityTim]

The IP address is coming from your DHCP server - nothing that FLSUN can do to change that. If your other DHCP printers have been getting the same IP address after a reboot, it's been the luck of the draw. That's why you can (and should) assign an IP address to a MAC address in your router's DHCP settings if the device is a regular citizen of your WIFI network. Price on the S1 is worth it, but is a bit out of my pocketbook range, but ... I see that the Super Racer is on sale for $299, making it a possibility.

[@UncleJessy]

Agreed BUT my main callout was about the slicer not allowing you to change it once set. You have to delete the printer and add it new again.

[@RocktCityTim]

@@UncleJessy Yep, I misunderstood your point there and THAT is a problem. I discovered this with the current OrcaSlicer 2.1.0 beta and the just released 2.1.0., so not just their version. I also learned that you have to delete and re-add the printer (which is why I know about the DHCP MAC assignment) because I added a new Sonic Pad that I'd not set the fixed DHCP address for yet 😬.

[@zmast333]

Even if the IP address is not static, they could still deal with that. They just need to search for the printer within the network instead of expecting it to always show up with the same IP address. For instance, Apple uses Bonjour for this. It finds local printers and other Apple devices regardless of their IP. I believe there's a similar mechanism used on Windows/Linux, I can't remember the name right now. I agree that setting a static IP is simplest solution and that's what I do for my devices. But most people don't know about IP addresses, DHCP, etc. On the other hand, one might argue that this is targeted more at businesses than hobbyists.
