They do decent job on larger models, but I would have preferred to have more airflow. Fortunately, with the Flsun SR we get dual part cooling fans and ducts. Having all these features wouldn’t help too much if the part cooling is not up to the task. The hotend fan start only after the hotend temperature goes over 50C. This fixed my clogging issue and retractions performed well after that.

In the future I will surely upgrade the hotend asembly with a bi-metal heat break and a proper Volcano nozzle to properly take advantage from the print speeds this printer is capable of.ĭuring my first 3D Benchy I discovered that the PTFE tube was not correctly installed, and I needed to disassemble everything to clean up the clog and install the tube properly. This makes the nozzle stick out substantially and I’m almost sure this is not ideal for consistent temperatures. Unfortunately, the volcano-like heatblock is shorter than the original. For regular PLA and PETG printing, the stock one should be good enough. While I would have liked to see an all-metal heat break, instead of the PTFE lined one, this is not a huge issue, and an upgrade is not that expensive. This means that your printing temperatures shouldn’t be pushed over ~240C, because the PTFE tube starts to degrade and release harmful fumes. The hotend is a regular V6 clone with a volcano-like heatblock, and the PTFE tube goes right up to the nozzle.

PTFE lined V6 hotend with Volcano-like heatblock The extruder is not the highest quality, especially considering the gear quality but I’ve used the exact same unit on other printers with good results and it performed well on the Flsun Super Racer.

It’s especially important to have a good extruder with this printer because you won’t be able to print fast with a regular style single-gear extruder. BMG Extruder cloneĬompared to the Titan clone extruder used on the Q5, the Flsun SR uses a BMG extruder clone which has a gear ration of 3:1 and dual gears which help push the filament efficiently to the nozzle. If you were to purchase a second effector as a spare, you could easily swap it and start printing again in less than 10 minutes. The whole effector assembly, including the cooling fans and hotend weight 264g.īecause of the way it’s mounted to the arms, removing the whole effector to service the hotend is really easy, and it takes less than 10 seconds. For part cooling, we get two 4010 radial fans with plastic ducts to direct the air close to the nozzle. The Flsun Super Racer has an aluminum effector with a V6 hotend clone, a volcano-like heatblock and a volcano nozzle. Even though there’s grease on them to minimize wear, they will fail at some point and right now I can’t see any replacements available. I’m curious to see how the plastic caps inside these fiber rods will work after a few thousand hours of printing. The weight of these carbon fiber rods is only 177 grams. Between each pair of carbon fiber rods, we get two springs to hold them in place. I’m not 100% convinced these rods are made from carbon fiber, but they are light and stiff. Carbon Fiber rodsĭelta printers greatly benefit from light moving parts and to improve this, the Flsun SR comes with carbon fiber rods. These belts will help with fast movements during printing, and I really hope more 3D printers will use wider belts in the future. They are not GATES belts like we get with the Ender 6, but they seem to be good enough. It’s also worth noting that the Flsun Super Racer uses 10mm belts. These tensioning knobs are a bit hard to turn because they are recessed in the aluminum extrusion but considering that you won’t really need to do this process more than once, we can somewhat ignore this minor issue. If you decide to adjust it, it’s extremely important to have the same belt tension on each axis, to avoid dimensional accuracy issues for your prints. On the bottom of each linear rail there’s a belt tensioning knob. This way, you have a spare if something goes wrong with the printer, minimizing downtime. I really like the whole accessories package you get with the Flsun SR, and the inclusion of a spare hotend with heater cartridge and thermistor is a welcome addition. USB Card Reader with 2GB MicroSD Card (no name – I recommend using a better one).Spare hotend (nozzle, heatblock and heat break).With the Flsun Super Racer, you get the following accessories: Even though my box had some shipping damage, I did not encounter any issues with the included parts. Thick foam is used to keep all the parts safe during shipping. The packaging for the Flsun Super Racer is compact compared to other 3D printers, while providing good protection on all sides. 13 Klipper and other upgrades for FLSUN Super Racer Flsun Super Racer Shipping and Packaging
