I tested Reprap Prusa and than I switched to the Anycubic Kossel Plus Printer. In only 7 Steps the preassembled Printerparts are build to a printer made of excellent produced parts. No twisted axes screws but well shaped rectangle shaped axes. The printer comes with 1 head with inbuild ventilator and a second ventilator for the cooling nozzle. A special sensor can be connected via magnetic panel to use the automatic leveling of the príntbed. The bed is fixed (!) and not moving. The movement is done by the printhead which is fixed to arms of a gyroscopic crane. Therefore once leveled leveling will be good for a long time. The printbed is heated but I use blue tape for better adhesion.
And the prinable dimensions are heavy: Z=300mm and the circle of ther printbed is 230mm.
Attached in the well documented assembly kit are several high quality tools to build and work with.
The manufaturer is from china but the communication via e-Mail is very good and quick. I blowed a board off by a failure of mine and I got one back for nothing within 7 Days.
Compared with the printing results the layer quality is lightyears away from the one I had with the Prusa Model. Fine printed surface with good tolearance of the values. I printed smal chairs of 4x4 mm with legs of 1 mm in diameter for a ship model.
The used slicing software is Cura from Utimaker and the OS is Marlin RepRap. Printer can be connected to Windows 10 via USB or it works standalone with data from SD Card.
Final statement: this is the best printer I ever bought and I am using it very often. And the Price on ebay in 2019 was 175 Euros for the assembly kit. Deliverd within 1 week.
