Suddenly, I am unable to print anything. I have made no changes to anything that I can recall. Worked one day, fails the next. Filament gets put on the plate and then is quickly set loose. The first things I tried different nozzle, different filament, different plate including one of the “holo image” plates because it had never been used so it would rule out any oily finger prints or whatever. None of these changes made any difference.
When the filament does stick for a moment, I can see that the nozzle is actually pushing to the side the line it had just printed but once the nozzle needs to cross existing print it comes up and becomes a spaghetti mess.
I removed the hotend and followed the instructions to check the heater screws and the 4 on the “back” were in fact loose and so I tightened them up. No change. I’ve done the manual bed leveling … I dunno, 6 times now and the problem still exists. I’ve done the manual process before successfully so not sure what’s different now.
- Do you feel that I am correct that this is a leveling issue or am I going down the wrong path?
- Any suggestions that might help me successfully level the bed?

Looks like under extrusion. Perhaps not hot enough.
I don’t know what it’s supposed to look like but to me, it looks like a 1933 Ford Grille. 
Just watched the video clip - looks like an adhesion issue - I have never used one of those plates but if I did and that happened , I would first try some sort of glue stick or liquid bed glue and if it did not work , then I would try putting a sheet of aluminum foil between the plate and the bed to raise the plate by a fraction of a millimeter - (perhaps after doing a full bed leveling so the nozzle Z offset is effectively a tiny bit lower that when the leveling took place without the aluminum.)
Perhaps also raise the bed temp a bit.
Good luck.
From what I had seen, I would think the nozzle was too close to the plate since it seemed to be bumping into what it had printed. I’m pretty new to 3d printing, so I do know that I don’t know much, so I tried the foil idea (very clever) to bring the nozzle closer to the plate and holy cow it’s printing OK.
So for the manual leveling process, to make sure my thinking is correct – what I was considering the nozzle to “just touch” was actually not touching enough, meaning the bed needs to go a hair closer to the nozzle? I thought I had a good viewing angle and used a flashlight but maybe I didn’t.
Oh, and I should say that for this now working print, I unchecked the bed level so that it would use the previously stored value.
If that’s what you thought it was it just shows how messed up my prints are right now, because it’s clearly supposed to be a 1934 Ford grille. 
I am glad my suggestion worked - seeing a gap of as little as 1/50mm is almost impossible - at least with my old eyes
Based on the video and the photo, the z-offset is incorrect, meaning the nozzle is not close to the plate enough to “squish” the filament onto the plate.
If the hotend has been worked on or replaced, be sure to calibrate the printer (from the display on the printer) after.
Also double check to make sure the nozzle is clean before doing the bed leveling. If there is filament left on it, the z-offset will be off.
Adding a sheet of aluminum foil between the plate and bed is a creative idea that I have never heard before. If it works it’s wonderful, but I don’t think it should be a permanent solution because it adds one more variable to the equation.
Do you have your bed type set correctly in the slicer?
