OK. I was printing Dino, the dinosaur from Flinstone. The model consists of 17 stl files. Biggest size is the Body. It takes 8 hours + to print.
I imported the Body file to the slicer. The orientation is with its front side facing East and backside facing West.
Then I did the slicing > saved it to a sd card > to the printer for printing.
Disaster. I left the printer running overnight. Woke up and found the layers had shifted to the right. See screenshot...….
I tried again, but this time I oriented the model with its front side facing South, back side facing North > sliced it and saved to a sd card.
Printing is coming along perfectly. It's not done yet, but I don't expect any issue this time. I'll post the result when printing is done.
MY question : Why orientation of the model in the slicer makes the difference?
