Door Scratches

Anyone else seeing the print platform scratching the acrylic front door? It’s really frustrating me.

Thanks for your post.
Mine appears to be happening in front of my eyes during prints. I see shaved acrylic accumulating in the center of the aluminum part of the print bed. As if the door is too close or the print bed is too far out. One thing i noticed is when you look at the back of the print bed, the aluminum is shaved off along the back by the pogo PCB. I wonder if that (where there is no black paint along the horizontal edge) is causing the whole thing to lean forward.

 

On my R2, with the bed all the way down, the gap between the front of the bed and the door is about the thickness of a penny (1.5 mm).

Does the bed have any play front to back? Should be ridged.

Also check if the door hinges and door latch are aligned and secured to the frame. It would be a lot easier to request a new door than to RMA the whole printer, especially if it is working well otherwise.

 

Already did. Been in touch with Jerry. Waiting to hear back on resolution.

I got a brand new door because mine was scratched during shipping. Then started noticing these vertical scratches a few days later. These scratches are NOT from shipping. Something is scratching the inside of the door, and it can only be the bed. Not sure how it is happening exactly, but I have these same vertical scratches on my new (2nd) door.

 

Look at where the aluminum bottom part of the bed tray is. There is a bend that looks about 45 degrees to make the lip. That is what is scratching up against my door. Either that is manufactured incorrectly, or the whole z-axis rod is skewed in such a way as to move the thing forward during raise / lowering right at the mid point of the door.
