Fastest Sub $500 3d Printer? The Flsun SR Super Racer Is A Beast!

[@philippkartusch1303]

I am printing at 150mm/s up to 260mm/s with this printer and can not confirm your problems. The Printer is super quiet and fast. Even when going over the recommended speed limit of 200mm/s the printer produces very good results. When printing with 100mm/s the results are excelent.

[@livethroughchemistry3173]

I know it’s been a while but can I ask what filaments you use

[@mr.e.484]

@@livethroughchemistry3173 I am now over 400 hours on my SR. I can say I can print inland cf.pla at 200mm/s with the same quality as if it were printed at 100mm/s. I have recently even printed it at 300mm/s with a costum profile and a year of tuning.

I print at 100mm/s with my FLsun Q5. No loss of quality or performance. Like the SR, the extruder is the loudest part. A 2208 driver helped and others mentioned that certain settings can quiet it further. If the SR is out of your price range or too big, the Q5 is worth a look! FWIW, FLsun support is very good.

[@beeblebrux2112]

What kind of settings are you using to get consistent prints at that speed? I've spent that last month and half with this printer, tweaked and tested a lot of stuff, and I end up printing in the 40-60mm/s range if I want good quality and a low chance of failure. Also had to lower the travel speed, tweak the acceleration settings, and also mess with jerk control. I still have a lot of trouble printing thin and high supports, or anything that's thin and tall (tubes for retractable swords, for example). It doesn't seem related to bed adhesion, it's more the print head torque, speed, and travel that is knocking the parts over. It's really "twitchy" with small stuff that requires small movements, still working on tuning the acceleration. Printing small and intricate things has been a real challenge that I hope to tackle sooner or later

[@baxrok2.]

@@beeblebrux2112 Tony, when I made that comment I had only had the Q5 for 3 months and even though I was printing 1/10th scale functional parts, they were extremely basic. I now print complex functional 1/10 and 1/24th scale parts, but not on the Q5. Like you, I could never get it to work and ended up just like you did at slow speed and tweaking settings like crazy to no avail. I went down to a .3 nozzle and even that didn't help. Now, essentially a year later, I use the Q5 as my prototype machine and I print my final parts on a different printer. Unfortunately the Q5, at least with my level of experience, just can not produce "small and intricate things." It sure as hell does not like straight lines or small holes! On the flip side, it can often surprise me and last week it printed a PETG benchy that was, dare I say it, almost perfect.

[@beeblebrux2112]

@@baxrok2. Ok, great to know, and thank you for the quick response! For a minute there, I thought I was doing something very wrong That's funny to hear about the holes, what is up with that?? I bought 6mm diameter, 2mm depth, magnets to do some cool stuff with. Made some exact dimension cutouts in tinkercad, and it's not even close to the right size. I printed the exact same cutout in two parts, one vertical and one horizontal. The vertical one fits perfect, the horizontal took a lot of exacto knife trimming to get it to fit. After some more tinkering, I had to make the .1-.2mm wider, and even then I had to work it a little bit to get them seated. Very strange indeed I'm getting better with it, though. Every model I slice and print, I find overall improvements to make. Have multiple models that I can run off pretty confidently with the right filaments, but just today, I had a 10 hour articulated lizard fail on two linkages, both fused. Other models have taken a fair amount of tinkercad work beefing up supports that wouldn't hold Also, do you get consistent temperatures across the whole build plate? I haven't checked it with a meter yet, but I'm getting worse layer adhesion toward the back of the plate. Wondering if it's the build plate or something in my environment (maybe a duct or something is blowing nearby ¯\_(ツ)_/¯) So, I call it a "finicky" printer to use, but I definitely wouldn't call it bad. And I totally agree with the reviewer that it's a really cool looking machine. Getting a good print off of it is so satisfying! And I watch it constantly while it's running

[@baxrok2.]

@@beeblebrux2112 Slicing takes practice for sure and it can get overwhelming. I like to experiment but I'm more interested in getting good prints so I backed off on messing with too many settings. Yeah, that hole thing drives me nuts, they are shit every time. Holes will almost always be off (delta or cartesian), but the Q5 holes are bad. To help with size, you can print a calibration block with a range of hole sizes to see how much you need to up-size or downsize your holes to hit your target size. Cura also has 'hole horizontal expansion' to help with that. Holes are one thing, but if your dimensions are off, say after measuring a calibration cube, you might consider contacting FLSUN. The calibration was off on mine when I got it and they sent me a program to re-calibrate it. Definitely helped. The Q5 build plate is okay (for PLA), and I don't have any known temp issues across the plate. I print all over the plate so I think I'd of noticed it by now. Do yourself a favor and get a PEI build plate. I just got one last week and holy crap everything sticks to it! lol Pretty much eliminates adhesion issues and I'm printing PETG. Agree, it's a great printer and I love it for sure. However, for small complex parts, it's best as a prototype machine.

[@digitalghosts4599]

14:00 regarding that knob, aside from what you mentioned, it can be also an artifact that results from very fast printing speed and incorrect cooling settings. In Cura, there's a Cooling settings tab and more specifically, in that tab there's a minimum layer time and minimum speed setting too. If you quickly print a very thin part like some nacelle, there will be so much heat transferred from the nozzle, the part will deform and the fan won't be sufficiently strong to blow enough air to prevent it. If the part is very thin and the "minimum layer time" is high and the "minimum speed" is also high, the slicer has no other choice than to stop the print head within the print perimeter to ensure the minimum time limit condition is met, which obviously doesn't make much sense - this is exactly what you observed. You can either decrease the minimum speed or you can check Lift Head option, which will make the print head leave the print area to allow for better cooling. This also prevents the filament from dripping into the print. Decreasing minimum time too much will likely cause the thin sections to overheat and warp.

[@dobbythehouseelf5597]

out of the 4 printers I have I love my Delta - it started off as AC Kossel Linear+, its got a ReArm & LV 8729's @ 64 steps and not had an issue or had to do any levelling since I complied Marlin 2.xx in almost 3 years

[@LarryGreen]

I purchased the Flsun QQ first, Loved this unit enough to pre-purchase the Flsun SR...the solution that I have found for adhesion (was using purple glue stick) is cleaning the hot bed with rubbing alcohol, then Magigoo...it holds firmly, and does not seem to break loose, even on large prints with gyroid fill...then when the bed cools...it truly pops off.

In newer firmware updates you can disable the beeping noise and power loss recovery, I believe this is in the eprom settings.

[@keezo1234]

Delta 3D printers are not faster for the reasons you gave. Delta 3D printers are faster because of the kinematic consequences of the Delta geometry. 1. Every movement made in the tool head requires the movement of 3 motors. This allows you to accelerate the tool head harder because you have the power of 3 motors contributing to each movement instead of a single motor as you would on a moving-bed Cartesian printer. 2. The geometry of right triangles means that small translations up or down in the Delta’s Z carriages induce large toolhead translations in the XY plane over the print bed. So not only do you get more force on the toolhead for harder accelerations, you get more XY translation per unit of that force as well. The extra speed of Deltas has nothing to do with the rigidity of the frame or the weight of the toolhead. Light toolheads make any 3D printer faster regardless of the kinematic architecture. The only reason light toolheads are more common on Deltas is because it synergizes with the faster kinematics. It’s a logical fit. Often times the opposite is true. Often times people use HEAVIER toolheads on Deltas because the speed lost to weight is made up for by the faster kinematics. This is why most Clay printers or printers with large heavy pellet extruders are almost always Deltas (see: Wasp printers). Still like the video tho 🙂👍🏼

Have you tried a really fast and reliable SD? Power Loss Recovery writes a log file to SD to record the layer information. I reckon that this write process is affected by the SD writer and/or card.

[@Jim_One-wl4ke]

❤SR ! I think the main reason it’s fast with Marlin is 3 motors driving the head at all Axis with linear rails. Agreed with retractions sound 5+mm. Awaiting a direct drive 36 moto. Then next would be klipper let’s see if it will match his big brother v400 😊.

[@TheGeordietheWitchandtheWench]

I klipperized my SR, I'm now at 800m/s and 100k accel ;-) Admittedly I have upgraded just about everything...

[@TechExploresNYC]

I would theorize that part of the speed from delta came from the fact that all movements are controlled by 3 motors as opposed to Cartesian printers where one motor does all the work and the other two (or Z in case of coreXY) just sit there.

[@bdog2200]

That honestly sounds like the exact reason, id be surprised if it wasn't.

[@eaman11]

Moving parts are a lot lighter on a delta.

[@Shoshk3]

I don't know if this is still relevant, but the issue with power recovery is the SD card not the board/firmware. It's pretty common since most printers come with the cheapest SD the manufacturer can get. You can get a class 10 SD card pretty cheaply on amazon and solves the issue, for me this happened with the ender 3 v2 and got an sd card for something like 15$ and no issues what so ever since.

[@cpace123]

So I have 4 filament printers, and my easy solution is a UPC. If have lost power to the house, and with that connected my printers just keep printing.

[@OldCurmudgeon3DP]

For my little Ole Ender 3 I have a 960VA on it. The software reports that I'd be lucky to get 6-7min out of it during a cut. That's plenty for most issues we have here, but worth noting it takes a large UPS for even a small printer for significant runtime on battery.

I'm still kind deciding what I want for a printer, and have been watching a bunch of videos to help me decide. One thing that I've never heard anybody mention, or thought of myself, you sort of hit on very briefly, "brownouts". ANY electronic equipment should be run on a battery backup system, not so you can watch TV when the power goes out, but it just evens out the power. 3D printers are no different, if the power fluctuates, for whatever reason, the UPS will just even out the power flow. I, personally, don't run my TV or my computer without a UPS. I've replaced the battery on the one I use for my TV 4 times, a whopping ~$12 each time. My TV is ~8 years old. Where I am, the power sucks. I have literally watched my light almost blink out like you were turning off-on really fast and heard the UPS switching to battery, it's probably the main reason my TV is 8 yo...that and I don't need a new TV just to watch the same old crap that's been on for years.

It's always seemed weird that people would choose to use glue stick/hairspray for bed adhesion when they could just use a brim or raft. Glue stick makes a bit more sense for an unheated bed or an application where you want a power failure to resume successfully after the bed has cooled down, but why introduce something to dirty the workspace? Especially for tall, thin prints with little bed contact, adding a brim or raft is the easiest and cleanest way to fix the issue

I think your missing the mark on a lot of these talking points and misunderstanding what goes into the quality of a part. I print 150mm/s on my CR10, the frame is far from the thing that makes that possible/impossible. Delta are not known for rigid frame, mm/s is not a good indicator of speed, the speed limiting factor is not the frame. Deltas actually have relatively weak frames compared to most printed and tend to twist at real high speeds. Just because you plug in 150mm/s does not mean your printing 150mm/s, the accel is probably really low, maybe 3 or 4000, so it's probably never reaching that speed. The reason the threads fit is probably because you weren't even close to 150mm/s, for a whole host of reasons I don't care to explain
