We always give this a “used – like new” condition because if it were new, it would have 0 hours of print time.  These printers will have around a week of print-time (see photo).  We always “burn-in” these printers by printing out the parts necessary to build the next printer.  During this week-long process of burn-in, we fine-tune the printer to eliminate common i3 MK3S kit build issues:  improper belt tensioning, phantom axis crash detections, grinding extruder gears, etc.  The burn-in process ensures this printer has been debugged and is ready to print out of the box.  There will be minor cosmetic imperfections such as tool marks on the black anodization coating on the frame that occur during the assembly process, minor cosmetic imperfections in the 3d-printed parts, etc.  Our printers are assembled from brand new out of the box clone kits, upgraded, burned-in, and then shipped to you.
It takes about 20 hours total to properly assemble, calibrate, and test a new i3 MK3S kit.  We are selling here to make money on our labor.
