I am noticing that my engineering bed is getting shadows from past prints - the first layer is the presentation layer and it is starting to show these shadows. I cleaned the bed like I usually do but that does not remove the shadows. I like the subtle texture of engineering bed. Has anyone resurfaced theirs yet with a fine grain wet sanding paper or something. Could I use a quick wipe of acetone (heard mixed results about this in some forums)
Also I am noticing that my engineering bed on some recent prints is starting to hold on to prints a lot tighter than it used to. Any thoughts on this? Nothing has changed and I have not used it that much.
Thanks
