I just got my X1C! Very Happy printing. So, for my latest version did my printer come pre greased? I know that Bambu sent a lot of spare parts. So it is not such an easy answer. I don’t want to grease them right now if I don’t have to. I don’t want anything to interrupt the gorgeous and shear reliable printing. If Yes, I need to grease, which is the correct type. Some came with the unit. Also, I have the DUpont white Lithium Grease with Teflon and the 3-in-one Lock dry lube. That I used on a bed slinger project. Thank You.
The lead screws should come with lube applied. The machine will pop up an alert when you should apply more but the following can be helpful.
I have not yet run out of the grease that came with the printer but have some Super Lube 92003 on hand when it does run out.
Also, there are models on MakerWorld for tools to help with cleaning and lubing the lead screws. I use the ones from @K2_Kevin.
