FLSUN QQ-S 90% Pre-assembled Delta 3d Printer Printing Size Φ255X360mm Lattice glass platform Auto Leveling Touch Screen

Product Information

With a maximum temperature of 270° C, QQ-S PRO can handle most common printing filaments, such as ABS PLA, PVA and wood.

The temperature of the nozzle does not exceed 250°C, and the temperature of the hot bed does not exceed 90°C. Thus, the energy consumption measurement shows that the mainboard, motors and heating element of the hotend require about 55 watts in operation, and the heating element of the print bed requires another 220 watts. In the middle of building the 3D printer, when the long sheets of the three sides are not yet installed, the device seams to be unstable. From March 28th to May 9th, the pre-sale of SR printer has officially ended, thanks to the support of 3D printing users to FLSUN and SR printer. Overall, you will probably have to invest a bit more time until the 3D printer meets all requirements.The individual operating points are rather text-based, but Marlin offers the option of setting German and many other languages in addition to English. In principle, both operating concepts are appealing, even if some functions are somewhat hidden in Marlin, since it is not always clear whether a screen element is also an operating element. However, the WLAN connection was partly difficult in the test, since the small ESP8266 is well shielded by the metal casing.

This manifests itself in jerks and later also in large holes in the walls, since the filament flow is not stable when the firmware repeatedly stops the movements of all motors briefly. There are no big surprises here in terms of hardware; the limit switches, hotend and extruder are standard parts, as they are also used in many other printers. Not only that but also printing with HIPS and flexible filaments with support materials would be possible. The sensor is magnetic, very easy to install and remove, it’s a well thought out system, and also very accurate.According to the printer menu, the mainboard identifies itself to be a MKS Robin Mini Board and the microprocessor type STM32F runs the Marlin firmware. he also said that it will not come with any accessories if somebody know what were the accessories out of the box and if they are needed.

In an emergency, the corresponding heating elements are on full power until they burst into flames or melt the surrounding plastic. The large and small delta printers from the Chinese company are primarily designed to offer high speeds. QQ-S PRO is equipped with a 32-Bit motherboard and a separate MOS module, allowing for stable prints even at high printing speed.As soon as the distance from nozzle to print bed is correct, there are hardly any problems with PLA adhesion. The print bed heating reaches the maximum temperature of 110°C specified by the manufacturer after 10 minutes, whereby the ambient temperature at the time of the measurement was 16°C.
