Z Lift on Start of Loop Path due to Shrinkage Settings
Posted: 16 Jan 2018, 11:02
Hey Guys,
Started using the material shrinkage settings in the Material tab to automatically inflate the gcode to take into account shrinkage. I noticed something weird when it was printing, a few layers up the extruder started to lift and lower at the start of the loop paths. As the model printed out and the height increased the z lifts were getting larger!
After some playing around I found it was being introduced due to the material shrinkage settings, when I set them to 0 the lift dissapeared, and looking at the gcode this was seen.
With shrinkage settings set:
A lift of 0.0053mm (not noticeable but it's there and gets worse higher up on the print- see later)
Without shrinkage settings set:
This next excerpt shows the z lift getting bigger as the height of the model increased:
This gives a lift of 2.1564mm
It seems weird that this happens due to material shrinkage settings so am reporting it as a potential bug. Can anyone else confirm this please?
