I use the "tried & true" procedure to level both my Ender3 Pro and my MonoPrice Mini v.1 Drag the paper, adjust the screws, repeat, repeat, repeat
I've added an additional mm manually. The nozzle just "dives directly" to the bottom of the "Glue Stick" "Painters Tape" or even "Aquanet" spray.
Neither is being nice to my nozzles or my print beds.
Octopi v. 0.17.0 running on 2 separate 3A+ Raspberry Pi devices. I do full OS patches before any print. They are much faster than a B+.
I've watched them with System Monitor and they barely top 10% in RAM or 10% in CPU load.
I'm using Cura 4.6.0 or 4.6.1. I haven't messed with either standard profile very much. Mainly on infill, with "normal" printing. FRUSTRATION R ME LOL Any & all ideas welcome.
