No, I just went to bed for the night
I would by it from you, but I'm broke at the moment, so not happening. I would though if I had the money though... as I really do like the Delta, and the Delta+ is hopefully a step up... maybe? possibly? And for me the upgrade kit is essentially free as I was originally a kickstarter backer, I only had to pay for the postage... so not much point!
Ah yes, the other thing you might be thinking... that would be what I am thinking about my other 3D printer... it is a PITA... and it will be a month or so before it will be around 95% satisfactory in function... but when it works it works well.
My apologies, I didn't realise that you were looking in from the side in that earlier video.
However, after looking at your latest video were it almost finished the movement test, I'm wonder if the head is going down too low, and is actually dragging the nozzle along the print bed, and that is the reason your print head is being knocked off. It might be worth removing the magnetic build bed and trying again, and see if it stays attached this time.
Alternatively, try running an "Autolevel with Clean Data" (Machines -> [your machine name] -> Commands), and see if it can do that. I'm hoping that will clear the current calibration data, and get the printer to realise where the print bed really is, and not drag the nozzle on the print bed. I can't test this myself as my printer is currently 3h20m into a 5h30m print job Having said that, I believe the movement test is hard coded, so would always fail if it is going down just a bit too low, and dragging on the magnetic build plate. That isn't an issue for most of us older Delta owners as we didn't get one, and the movement test has only just been introduced in a recent version software, so could still have bugs.
Otherwise, I'm with BoozeKashi... it could be those foam pads being a pain... as they might be adding just enough extra tension to make it easier for those joints to pop out. However, since I can see the drag marks on the build plate, check that out as it does seem to be a problem, and could explain the detachment happening there.
You will be able to printing with the Flux Delta+ soon, just don't give up! It just takes a little tinkering and tuning... and the support guys are really good and have always resolved my issues in good time. Hang in there!
btw, since voiding your warranty was a concern... as I indicated earlier, if support told you to open it, you are still protected. To see that in writing, look no further than the Flux Help Center -> https://flux3dp.zendesk.com/hc/en-us/articles/215329448-Can-I-fix-the-machine-by-myself-
