Hello everyone, please tell me about the maintenance, are there any manuals on it. Is the stock grease from the box suitable for lubricating the printer? And what can be lubricated with it? If not, which one do you recommend? And what can be lubricated with, motors, shafts, rails with oil, and belts with grease? Or can all this be lubricated? I searched for a long time on the forums, but there are only disputes about what is better, and I'm new to this business, so I can't really figure it out at all, please help. The K1C model
