The First Layer of Supports Is dragging/not sticking
I am trying to print a fairly small and simple table spinner type-thing. (The thing from Inception). I may have overdone the supports, but whenever the first layer of the supports prints it either curves up on the edges or completely fails and does not stick.
I have tried every type of factory reset and calibration there is. I've tightened all the belts and washed the bed with dish soap once in a while and isopropyl alcohol before every print. It seems like there is no surface adhesion at all
What material are you printing? If the bed is indeed clean, Live Z would be the first think I'd check and lower until I get adhesion.
Clean bed with dish soap. use hot water, use a lot of water, clean several times.
The print a few squares, so you can adjust the z layer for every square different.
Then start to high with the z layer, then lower for every square.
I've adjusted live Z many times but I might try @peter-m-3's method to get it further adjusted
This is how I do it:
but I use a smaller square and change the Live Z 3 or 4 times per square, not just on the diagonal.
Actually, I use the standard Prusa first layer calibration to just get to the point where my filament sticks, then I use jeffjordan's approach to fine tune it.
In the printer settings , set it to 7x7 calibration.
I had the print was going very well for a relatively long time. Just now the nozzle randomly crashed into it. Any tips about that or is it just a weird mistake?
