What is the problem?
When checking current layer, I see the double of the reality compared to my Simplify3D layer display
Checked with a caliper with S3D as a Z reference, seems to be exact double...
At the same time, the time to achieve is ridiculously low compared to S3D assumption, and my own calculation. 2 layers/min and 900 layers mean around 7 hours, Octopi says 2 hours....
What did you already try to solve it?
Just divide displayed layer count and manually calculate the TTA
Have you tried running in safe mode and if so did it solve the issue?
