@Bikeracer2020,I am about to chuck this thing out the window. I have viewed so many videos, and such and nothing stick to the bedplate. Not even new ones. I have tried textured and PEI. I ended up effing up the PEI plate because I kept moving the head closer until I crashed it. It just peels off as it extrudes. Its completely worthless. In fact, the benchy you see above was done with ALL FIVE screws on the extruder completely disengaged. You would wonder how it did anything. But, I actually got it to stick good enough to get a benchy out of it. Now, with the extruder properly installed, I cant get a single layer to stick right at all. I have tried some very simple models, and a level test and its all the same. New bed plates even. I'm using what I thought would be the easiest material, PLA. 210/50, 210/55... zero offset through -0.2 (crash) and nothing sticks. Even the parts that appear to have sticked, it takes barely a flick with the finger, and it pops off. I got lucky and got a couple models to finish, but even with that, i had several pop off part of the way through. Adhesion sucks and ive exhausted everything. I had a stratasys fortus 250m at my work, and that thing was a breeze compared to this. I have to ask the question if these qidi are just crap, and do you have to rely on luck for every print to get anything usable. Or, do you consume $35 bedplates evey time. I'm regretting this. It might even push me to a heart attack. I have had a very few things that drive me to rage, and this is definitely one of them. I need to see some success here, and quick.
