My prints are getting detached from the bed at exactly the same height, (tested with 2 marvin prints and 1 benchy print).
I’m not sure if it’s just usual adhesion problems because it happened at exactly the same layer each time.
I actually saw it happen with one of the marvin prints - everything fine, good solid base, then it looked like the nozzle pushed on the part and it popped off the bed.
The printer is rather new, but previous prints have turned out fine. These prints are the first ones after I changed the extruder idler block, after the stock one developed cracks.
