Hello,
first of all, yes i read tons of articles about this and tried the solutions.
i design with openscad then slice with cura 3.6.0, save it on an sd card and finally print with the TEVO black widow.
the problem is every now and then i get a layer shift.
thirst i tried all the sollutions, but the i started to experiment.
- when i start the same print again i get the same layer shift at exactly the same location and the same shift.
- when i slice again with cura there could be no layer shift or a new layer shift
(this with the exact same setting in cura)
so
- if it is a loose pully it should happen more randomly.(even if i wanted i could not get a loose pully to skip at axactly the same spot twice at a row)
- if it is a defective SD card, it would be solved by changing the card (tried 3 cards withe and without extra formatting)
- if it is a setting in cura, it should happen exactly the same after re-slicing withe the same settings
- if it is in the printer firmware, it should happen with every print.(re-installed the firmware, and it was the same firmware with the previous cura version wich worked fine)
in my opinion it starts to look like a bug in cura, evenmore because it started from cura 3,6,0 and didnt happen in 3.5 or 3.4.
now i have a big thing to print (3days printing and a lot of filament) and have to gamble
will it print or shift......
and if it shift will it be will it be 0.4mm or 10 cm (both happend, 10cm overnight and we all know the mess i found next day....)
anyone any suggestions?
