    Recommended but .....
    I chose this printer (my first printer) especially for the renewed style and the improvements made to the Z axis compared to the sister U20, here in fact we have a double motor on the Z axis and for the few tests I have done so far I can say that of the usual problems read around the forums, not even the shadow here. Everything arrived in an impeccable packaging, the inside of the box is preformed and there was no possibility for the various components to move during transport. Once the printer was assembled, I realized that many of the adjustments and tightening (even of the parts assembled from the house), needed a revised one. The plate was practically very slow on its track, as were the straps of the various axes. The cables run inside the corrugated cut on one side and especially those for the Z axis suffer a lot when printing at the maximum height, that is 400mm. I tightened everything and switched to the ignition and setup to find the right leveling of the floor. Here I immediately realized that something is wrong with the Y axis, it is as if the head (and therefore the extruder) could not reach a maximum stroke of 300mm ... actually I am still studying the question why in manual I can move freely around the entire plate, while in leveling or printing this thing is more than evident. However, I strongly recommend this printer, solid and easy to assemble, I am sure that once I find the solution to my problem (a matter of days), it will know how to satisfy all my needs. Brava Alfawise you made the center again this time ;-)

    Excellent printer el prices, but ...
    The alfawise U20 is an excellent printer for the price. Assembly as simple as possible, great and high printing surface, double motorization of the Z axis, color touch screen. The printing is good quality input, even if we can have the appearance of salmon skin, it is really great for the price. The fans are pretty quiet (relatively), the stepper motors, however, are a bit more noisy than on some printers. Small least are especially at the pre-assembly, even if the printer only happens in two parts and its assembly is simplified to the maximum, it is really necessary to check all screw tightening. I got for the model has been damaged threads at the "nuts" of the Z axis, which implies a new thread. Once these issues resolved, everything goes really for the best. Some improvements could beings useful buildtak of the bed hangs a little too much, even completely cold, sometimes it's really hard to shift parts and the user menu is not very intuitive. For my part, I added TL Smoothers, reinforcements for the Z axis you can find easily on Gearbest and I also changed the wheels on wheels polycarbonate less fragile than the original. Otherwise, go ahead, for the price, it really is happiness!

    Alfawise u20 one
    I chose this printer because it had good reviews and I must say that the five-star deserves all, just arrived (early) I immediately mounted, about an hour, the plate was detached from the base so after it mounted and tight springs almost full I did two times the calibration because of too much space between the nozzle and the glass in the first leveling, I find it very good and I would recommend it if someone asked 3d which printer to take, value great price, of course comes with the bare minimum but a once mounted every man can set up as required with the colors that own terms. I'm happy, a little something to uppare for perfection but for a neophyte who could go so well. I think further, not now ride on the smoother, the effect is there but salmon is not very pronounced and does not even make all this noise in the press. I think it's been updated in the first laps components, I saw video of shoddy pieces but this does not seem to have these problems. It has the glass plate which in some reviews is missing. Overall 5 stars.

    Great product
    The object reaches well sealed in a rugged box. The printer is partially assembled and can be used in less than an hour. any flaw I found in the pre-assembled parts that are solid, well recorded and with the right tolerances, the overall quality is high. I tried it with the PLA, the product produces well-made prints without the need to search for advanced settings (which can then be discovered and set with all then calm). The software bundle that comes on the SD card is full (though dated) and pressed to access the most advanced parameters (including step per mm, settings that do not appear on the touch screen). I use it with care and Octoprint, and although my first printer, I was struck by the simplicity of use.

    Printer for the lazy
    Beautiful and high-quality toys. Made very solidly, two synchronous shaft, carefully wrapped wire touchscreen color display, printing out of the box. Everything would be fine, but .... Stepper motor drivers have radiators. giblets ventilation absent. The head of the park is not on the table (it is necessary to collective farms trailer extender). Fan thermal barrier is too noisy. Firmware only with flash cards. It stated that the printer is sewn open source Marlin - lie. Make changes, and to calibrate the flow of steps, configure the printer by itself, written in the memory card or connect heights BLTouch not get. If there was a choice now, I took to Alfawise U20 with remote unit, and better Tevo Tornado. And now I will change the charge on the SKR. Unfortunately, I can recommend this product to those who are looking for 3D printing only entertainment.
