That waviness is in your last vid was weird, I've never seen that before. It kinda looked like it just wasn't sticking to the bed...what brand of filament is that, and what are you using for bed adhesion?
The Waviness happens occasionally. It usually irons out on the 2nd pass through for the skirt. I am using the Purple Glue stick, two lines (horizontal/vertical) per the instructions.
UPDATE:
Failure again.
My next step is to go do another Z-Height calibration, but before I did that, I wanted to run this by everyone again...
I was able to print a TREX skull. Yay! Yet, it took two tries. The first one failed at 96% on a 13 hour print. Yeah, I had said a few words at that time. What occurred was it came unstuck from the bed and was knocked over. I noticed very small amounts of unleveling. A specific movements, the Hot End would hit the side of the part and make a CLICK noise. There was nothing I could do - so I continued to let it run. I increased the bed temp some, trying to make it grab a little more - but sure enough, it broke it free from the bottom.
I printed it again, but this time I used a raft. That did the trick. It still was clicking / hitting the side of a part at various places though.
One thing it did that isn't right: about 85% complete, the layers started to visibly separate. It made it look like it was leaving "cracks" into the part. Lucky enough for me, I was able to finish the print and put some superglue on it. Else, it would easily pull apart. Yet, the rest of the entire part was perfect.
On the next part (JAW for the TREX) - I have had 3 failures. The first was knocking the part over (with raft). The next was misasligned layer. I am not sure what occurred, but the part finished. Yet, it did it on pure luck, as the right side of the jaw had a layer split. In the middle of the jaw bone, one layer moved about 1/2" towards the Z-Axis from the center. If looking straight down at the part, it would look like an over-hang kind of. Further, the layer was not attached at all. Obviously there was stringing, etc. everywhere. The last one failed with a knocked over part as well.
The area of errors are not that far OUT of the middle of the glass plate (i.e. towards the edge of the bed). Rather, it is just vertical in height.
What would cause this? The JAW (2nd piece of the TREX) is much easier to print than the Skeleton - yet it fails every time now.
Thanks,
