The printer comes well packed in a 600 * 360 * 160mm box. Package weight 8 kg.
The complete set of the printer is usual – a set of tools for assembly, nippers, SD card with software, SD reader, instructions, some plastic for checking the printer.
Assembling the printer, as promised, is very simple, it takes 20-30 minutes for an unprepared user. After assembly and automatic alignment (according to the instructions), it immediately starts printing test models. Well, now in more detail:
The frame of the printer is assembled from a steel base (1.5 mm) with curved stiffeners, an upper box stamped from the same steel and stands from an aluminum profile 2020.
The uprights are connected to the base and top with steel brackets and screwed with M4 screws. As a result, the frame is not rigid enough, although given the fact that the print head weighs only 150 grams, this may not be so scary.
Carriages with 3 rollers moving along the grooves of the aluminum profile. One roller has an eccentric to compensate for the gap between the rollers and the profile.
The anodized profile is even, there are no problems with the movement of the carriage. The design of the belt fastening is interesting – it is located inside the grooves of the profile. On the one hand, it looks aesthetically pleasing, but on the other hand, it is difficult to check the belt tension. Unlike many Chinese printers, there is a primitive belt tensioning system – a frame with grooves for two screws. The rods are made of carbon fiber with fisheye bearings. Half of the bearings, as expected, with noticeable clearances. The length of the rods of 215 mm is maintained with good accuracy (+ -0.2 mm). The effector is a 3 mm thick aluminum plate. A radiator similar to the E3D V6 is mounted on it, but it is not fastened with a standard fastener, but with two screws from the bottom screwed into the ribs. In addition, the thermal barrier is not screwed into the thread (as in the E3D V6), but is inserted into the hole and tightened with two screws. Thermal barrier with a 4 mm through hole, into which, up to the nozzle, a Teflon tube is inserted from the extruder. Radiator cooling fan 4010 (the noisiest part of the printer).
Cooling turbine model 4010, one-sided, not very efficient. The extruder is an analogue of Titan, made quite soundly.
The heated working table is made on the basis of a 1.5 mm thick aluminum plate on which the ULTRABASE glass is glued. It is rigidly fixed to the steel base, with three screws through the bushings. Table power 110-115 W. It heats up to a temperature of 60 ℃ in 2-3 minutes, to 100 ℃ in about 10 minutes. The printer is calibrated using a removable magnetically mounted contact probe.
All electronics are located at the top. Power supply unit 200 W 24V 8.3 A. Dimensions 160 * 90 * 30 mm. The measured power of the printer at maximum load (heating the bed, heating the nozzle, and movement) does not exceed 190 watts, while the voltage of 24 volts practically does not drop. Under normal printer operation (PLA printing) Power consumption 100-120W. We can assume that the power supply is quite sufficient, although without a power reserve.
32-bit control board – MKS Robin Nano, based on STM32 processor. Along with this board comes a touch screen, in this case it has a size of 2.4 inches. Not very big, but quite comfortable. All this is cooled by the 4020 fan, which runs very quietly.
