It is great. If you want bang for your buck, get this 3D Printer

The printer is no easy to build due to the poor assembly instructions. Unfortunately, one of the electric motor for the Z-axis is not strong enough, making some problems, especially with a variable offset in the Z-axis. It's also not possible to control the second head (motion) with the LCD screen. Moreover, there are no connecting instructions for the auto levelling unit. Nevertheless, for the price, it is still a good printer.

Truly a DIY project. If you have never assembled furniture that came in a box or never picked up an alan wrench, stay away. If you are, however, the kind of person who grew up building legos and slapping cheap dressers together... give it a shot. The secret to is to pay attention to the orientation of the parts in the basic assembly instruction. Now for the wiring... yes there is the documentation. Read it and get what you can out of it.

After some initial problems with the printer I would like to say that the seller has been very responsive in resolving my issues. Initial issues with the printer are as follows. All have been corrected by either me or the seller.

1. Initial MAXTEMP error and the extruder indicated a temperature of 357 degrees at room temperature. Thermocouple set screw was too tight, shorting out the wires. Loosened and re-positioned.

2. Fans slowed down when power supply loaded down with both heaters and all motors running. Power supply read 11.75 V no-load and 9.6 V under load. Seller replaced power supply.

3. Extruder heater started fluctuating wildly and then stopped working entirely. Extruder heater voltage at the controller board was 0.5 V. Seller replaced the MKS controller board.

After initial problems were solved, this printer produces very good printouts.

Z-axis uses 2 stepper motors. One of them was kinda stuck, it was very hard to move by hand (unpowered) and as a result it was often missing some steps. This was fixed by itself after some time. The other stepper motor moved in the opposite direction as it should, this resulted in 4 broken linear bearings. After swapping 2 wires on the stepper and buying new bearings all was fine.

Wires from power supply to the control board are too hot, they should be thicker.

When I start the printing, the bed and nozzle are heated first. This takes some time but you can not just leave the printer because the Z-axis positioning is not very accurate and printing sometimes begins 1-2 mm above the bed.
