Unfortunately, the calibration quality from the factory was terrible, which is unfortunate on such a superb printer. My Y-axis […][Continue reading]
After finally getting my Cetus3D MkII 3D-printer I was eager to start to print. When I started through the steps to calibrate the printer by adjusting the build plate height, but the print head/nozzle refused to get close enough to the build plate to finish the calibration! The cables on the motor came in contact […][Continue reading]
