I made my own giant delta. I sorta rebuilt it a few times, and the most recent iteration, it has a 500mm bed (mains powered heater)-- obviously as a delta it can only print the diameter, but the actual bed is square, which makes sourcing a flex sheet and heater easier. I have a large CNC, so I machined the aluminum parts -- including the bed and things that hold the bed. The uprights are 1500mm, and it has an electronics basement, so sorry to mix units, but it's effectively 6' tall. I am using linear rails, not brand name, but well made ones. Actual build envelope the true cylinder (not counting the cone) -- is 490(diameter)x740 height. I made a relatively light weight effector -- and had it SLS printed out of glass fiber nylon. To that I have a slice mosquito magnum with a generally permanent .8mm nozzle -- I have a 1.2mm nozzle I will be trying for some bigger prints, with a direct drive Sherpa Mini extruder. I recently upgraded to RRF3 on the duet board, and after input shaping calibration, accelerations are at 6500mm/sec^2 , no ringing on at well over 100mm/sec -- note I am using a .8mm nozzle and .4mm layers. Doing some additional tests I need to brace the towers, as I do plan to update the enclosure with 2x4 lumber and secure the uprights to the enclosure to mitigate vibrations. Deltas are a lot of fun, and I will be making a large near life size character for my 6 year old son on it -- as soon as decides what he wants. He first requested an among us -- now he is over that.

Great video dude, I don't think i have a single question to ask.... really got all I needed to know from the content :). I run an Anycubic kossel linear plus and this new FLSUN machine looks like a monster! looking forward to your next delta video

My Q5 is amazing. It prints right out of the box and is easy to setup and use. I was thinking about this printer yesterday actually, glad you mentioned the newer version they have in the works. Also, deltas just look so freakin cool lol

I still have my original 3d printer, the Rostock Max V2. Haven't used it in a while but am going to try and get it set up again just to have it for funsies. It's just interesting to watch it do it's thing.

Im so glad manufacturers are no focusing on speed and build size this year. once printed TPU ON MY i3 mega with all my PLA settings because i was high and fell asleep. woke up to a perfect print, that kind of risk i will never take again. would love to see a consumer grade SCARA arm type printer

Ive had this machine for a few weeks and all in all its been very impressive. One thing i will mention. You are correct that you shouldn't have to use the probe to relevel often, if at all. However, when i upgraded to the latest FLSUN firmware (v1.3), i went to start a new print and my level was off and the nozzle ended up grinding against the bed. There was no indication in their firmware upgrade instructions to do so, so just a heads up for anyone upgrading firmware. Do relevel before starting a new print with the new firmware to save yourself some peace of mind.

PLEASE keep us updated on your progress with the SR! I just got it as my first printer and been having a blast! I'm interested in any settings or upgrades you may find that help the print quality.

I have a qq-s pro. I liked it but always had first layer issues. So I tried Marlin and it helped. It sat for awhile. I've been messing with Klipper on my other printers and found someone that made a config for that printer. Now it's unbelievable and like a whole new machine. 1st layer goes down every time.

I've had my SR for about a year - it's my favourite printer - replacing my Ender 3. Added a V2.0 BMG extruder, PEI flexible bed, full size Dragon heatblock, and 0.6mm nozzle. I love watching it print - and it's so much faster than my Ender.

looks like an excellent workhorse for the newer printer that wantsa big fast build

i also own a SR and i love this printer! This is my 7. printer :-)

I happen to like my FLSUN SR it was easy to assemble and once you get the Z height set properly and run the bed leveling sequence, you don't have to adjust anything until you change the nozzle. The bond-tech clone extruder is a little loud at the stock setting but works better if you increase the retraction speed. I find retraction speed at around 130 mm/s works good for me. I did order a new all metal extruder. Also the power switch is a point of failure, but is easily repaired or eliminated. I removed the power switch on mine and use a power strip with a breaker built into the power strip. Also added RGBWW LED lights, printed new axis "feet", spool holder and tool holders. FLSUN had me at Speed Racer...I mean Super Racer. I look forward to the new FLSUN 400.

I honestly didn't know deltas were that different from cartesian so I'm looking forward to learning even more from the delta video

I have an SR myself and I don't like the extruder either. I bought a Sherpa Mini extruder so I'll be converting it to DD soon. My most liked upgades so far are a bimetal heatbreak (get the 27mm one - overall length; for CR10, I think) and a full size volcano block. I had a problem with filament getting jammed into a small gap between nozzle and PTFE tube, which was pretty annoying.. Regarding the extruder: I have replaced a similar generic BMG clone on my other printer. I too went with a BMG V2 by Trianglelab and could not be happier with it :) I can't recommend that thing enough

I have no experience of Deltas but I reckon the extruder ought to be mounted on a tri-pivot platform between the three vertical slides. That way it's always a set height above the hotend (and would point directly at it) but without putting any extra mass on the effector.

Unrelated I've been using CHEPs ultrafast CURA profile(settings cloned from ultimaker printers) and it saves a TON of time...need to tweak it a LOT(especially for petg) but CRAZY FAST once you get it working- I think the profile optimises acceleration and travel settings

I print wearable shoes on a delta using a zesty nimble. Highly recommend it for flexible filaments!

Great review man 😊Is the extruder some kind of triangle labs or clone of one?

I have had my SR for a week or so now. I love it! I'm new to owning my own 3d printer and am learning the components. What extruder would be the ultimate upgrade for this printer? There are so many options. Everyone is recommending it, but I can't figure out what to buy.

It seems like the extruder has some weaknesses. What would be a better upgrade? I've read the teeth tend to chew up the filament causing failures. What's your thoughts about buying a flexible build plate and putting it over the glass to get better adhesion?

Awesome video now I just need to see how hard it is to replace the tubing and the extruder

Out of mind 🤯🤯

looking forward to seeing how this goes my ender 3 pro i can have running upwards of 500mm/s on big prints litterally had it at 1000% on my bigtree marlin on a box print plus some jerk control but this things a beast of a out of the box printer im yet to see the need to upgrade my ender except purely for larger build volume print quality and speed is nuts for only a 40w heater and stock hot end besides direct drive conversion why does it have a 3 to one ratio? as thats usually for the smaller pancake motors thats a fulll size 45nm motor it can drive directly and super fast

Separate retraction from extrusion, Robert is your parents sibling. Mount a small solenoid between the hot-end and the Bowden tube fitting such that when actuated, the Bowden tube fitting is pushed away from the hot-end. Rather than pull back a length of filament through the tube, move the end of the tube! New Retraction-cycle: 1) Stop the extruder 2) Energize solenoid to retract filament 3) move effector 4) de-energize solenoid to return filament to feed position 5) resume extrusion. Filament is no longer being 'chewed' by the extruder when lots of retraction occurs. Need to change the firmware a bit...

I had to build my own marlin version and one thing anyone interested should now that the touch screen needs the 11500 Baudrate. The touch screen itself has a microSD card under the case for updates and uses only 4 wires to communicate with the Robin Nano. I was stumped for Days trying to troubleshoot why the touchscreen only showed the FLSUN logo when using a few community Firmwares. I don't know how they did it but I believe the LCD communicates over Serial like octoprint does.

Hey, cool video ! The link for your TPU profile is dead, can you upload it again ? :) Thanks!

Really should use a tubing cutter or sharp razor to cut the capricorn tubing. Scissors crush before they cut and can cause a lot of resistance

I absolutely LOVE my SR. All that really needs to be upgraded is the extruder, ptfe tube and MAINLY the heater block. After I did this I was able to print at 150 mm/s with amazing results. I can also get great results at 200 mm/s with my Ludicrous profile. A 10 minute benchy... at 75% scale. Yes with a few updates this machine is a true beast. Let me know if you want to try the Ludicrous profile or see it in action.

Hi, I can't download the flsun sr tpu profile, it tells me pages not found. Could you update the link?

Can you do a video comparing Octoprint, Mainsail and Fluid. How to choose what's right for you?

for some reason am unable to download the TPU profle for flsun SR. Can you please reupload. Thank you

Should check out the OMG V2. Really nice all metal extruder

I have a FLSUN QQ-S Pro and I have an opinion on the Super Racer and that is "It's overkill!". Buy a delta printer because you want a delta printer for diversity or because you think the motion looks cool but don't fall for the hype on speed. Even at modest, faster than cartesian, speeds the artifacts are clearly evident. You can see ghosting and other visual effects unique to delta motion. Whether you're throwing a lightweight print head about on a single axis, or on three, the laws of mechanics and physics still apply. I bought my QQ-S Pro for about half the indicated price of the Super Racer. It has a Titan clone extruder and V6 clone hotend. It makes no pretence about offering huge flow rates (and thus printing speed) but produces decent quality prints reliably. The only downside I see with my printer is the fixed print bed which means that you need to take great care to avoid damage from nozzle scrapes but that comes with experience. This, in part, is why deltas weren't advised as a first printer. Will the V400 improve on the Super Racer or is it just another "new" delta for KZfaqrs to review and recommend their subscribers to buy?

What is a Extruder that doesn’t suck in your opinion?

No fan of Delta-Printers, but thy are fascinating to watch Thanks for your experiences with all of us 🙂

Checked the description and don't see your tpu settings

Seeing that Benchy failing, makes me wonder if future printers will have a camera that monitors the printer, and sounds an alarm when things start to go wrong.

the bmg lgx fixes the issues you metion .. its by far the best imo

I have one, great printer.

2/3 of my printers have bmg clones from TL, I love them. You know you can just pull open the lever instead of messing with the tensioning knob right? :P

I'd like the purge line gcode from this printer for my qq-s.

Yeah I bought one of their brands the Flsun FQQ and that was a nightmare the printer had fell apart I was disappointed with the customer service never had it fixed haven't heard as a door stand And you're lucky that they contacted you back they laughed at me told me to figure it out

Great review. Can you share your purge line code for a Delta printer? I could never figure that one out.

I have the QQ-S Pro, and haven't been that impressed with the auto level system. Manually need to adjust after which really, shouldn't be necessary. Looking forward to the VL400 to see what that can bring. I only really care about height the lack of PITA leveling these were meant to bring. I print PETG so overall speed isn't important. layer shifts have plagued me though even with new belts.

I have the SR, with LGX light direct drive, The extruder stock is crap and sucks worse then any other clone, You can also change the accel to 3600 in the firmware from the 2800 stock with no issues.

FLSun just dropped a pretty big firmware update! Check it out if you can. Hit me up if you have problems installing it!

pronterface is easier than octoprint for my flsun qqs to do esteps and the whatnot

I have a Delta printer 300 by 600, no need to level the bed ever.

Love your vids man but you should add music to make it more interesting and to make those moments of silence welcome man :)

I dont understand the fuzz around delta. It may look cool to someone but for proper printing you can use much better motion systems. Delta is good for pick and place robots. For cheap money you get cheap product. Though that is not even cheap but oh well.

7 min benchy = shipwreck :D

Actually FLsun is illegally using the firmware on the SR, since they refuse to release the complete source code of the binaries they distribute. And they didn't release ANY source code of the newest version.

In itself a good printer only a disaster to get a really good first layer over the entire bed. As a result, this printer has become unusable for me and it is only gathering dust.

First Again!!!

Get out of my head!
