Feature request: lift Z on retraction, except on first N layers #3057
Comments

Maybe an option like that would help but also changing the heat settings is another way to fix this. Can you post a picture of one of your printed models with the problem? What type of print bed do you have? Also are you using a skirt and raft? |
|
I am currently working on a Gcode Post Processor which eliminates z Lift for a certain number of layers and for short travel distances. |
|
Cool. I always went with the heat settings to fix problems like this but anything that makes printing easier is greatly welcomed ^^ |
|
This would also be addressed by #1316 (which discusses e.g. auto adding "mouse ears" on sharp corners) |
|
This is complementary to #763 |
|
I'll add two new options:
Both will accept an absolute Z. If |

Please can the "Lift Z" option in Printer settings -> Extruder 1 have a "except on first N layers" option. I generally find "Lift Z" works well, however on prints with sharp pointy corners it tends to cause that part of the print to detach from the bed if a lift occurs at that point in the first layer or two.
