I have the same issue, and I have deleted the passage. Will see on the next print if the issue is resolved.
ps: I am using version 01.07.02.00
I just had the same issue: at some point my A1 mini kept pausing every 30 mins on a 13h print… Ended up ruining my print.
So I read a bit, found this thread and BL’s wiki on the topic. Did you know that if clump detection is ON, there is an area of the build plate on which you should NOT print anything! If you do, when the nozzle lowers, some part of the whole extruder/fan/nozzle could “touch” your print and the printer will detect this contact and trigger the pause+error. For the A1 mini I think it’s one of the part fan “arms”.
This “dead zone” is shown below for the A1 mini (looks like 28 x 25 mm). It is described in coordinates as “(156, 152) ->(180, 180)”, which I don’t understand.
I had the same problem. Here is the simple process I followed to resolve it:
-> Removed and cleaned the build plate
→ Cleaned the heated bed
→ Retightened the heated bed screws
→ Vacuumed up all the filament debris
→ Cleaned, re-oiled, and regreased the guide rails
→ Silicone sock had a small tear → replaced it
→ Removed and cleaned the nozzle—including the mating surface!
Problem solved!
I used isopropanol for the cleaning.
