Sudden but now consistent de-adhesion
I hate to make this post because I read the pinned post about dealing with blobs, and I'm sure there are quite a few around, but I cannot find one that specifically fits what I'm dealing with. I have been happily printing with my A1 for months and loving it. I've recently been printing these poker-chip things with words in the top and bottom layers. They've been doing great until Monday when I decided to get ahead of things and clean my plate.
Since then I cannot get anything to adhere no matter what I've tried. When I cleaned the plate the first time - and every time after that - I washed it as hot water as I could, used dawn dish soap with a sponge, scrubbed pretty hard, rinsed it in hot water again, and dried it thoroughly, all without touching any part of the plate with my fingers, except the very front where the test lines go. As you can see from some of the pictures, that's the only part that does adhere.
Sometimes I've gotten something to adhere, like a blank chip, but then I tried a slightly more complex one and it would de-adhere again. And now, I can't even get simple shapes to adhere.
I've washed the plate carefully many times. I've taken the hot end off and carefully put it back on, I've carefully scraped off the plastic from the nozzle with a bronze wire brush and gotten it all from inside the silicon shoe, I've checked that the screws are tight.
Do I need to start replacing stuff like the plate or hot end or something? I just feel like I've tried everything. ;_;
