This may have been a post already, I tried searching it and I apologize if its a commonly asked thing.

So after doing long prints I have noticed some brown dust or possibly rust along the middle parts of the rails where the tracks slide. I wouldn’t think its rust but I just wipe it off wish a tissue and continue with my prints. I haven’t had any issues at all with my printer _knock on wood_. But I just want to make sure I am taking care of it properly. Is there anything I can do to wipe down the rails or a specific product that would be ideal. Or do I need to keep them oiled with something if so are there any recommendations that you guys can give me.

I appreciate any advice and help. This is my first 3d printer and I want to keep it healthy and happy.

Nope the dust is normal just wipe it off with a tissue and your good… long term there is some grease you can put on the internal screw. But you shouldn’t need to do that for at least a year or two
