[solved] How can I skip the first x layers of a print?


a co-worker printed the top part of thingiverse.com/thing:13578 and didn´t notice that slic3r 1.1.7 produced an error message and didn´t slice the last top layers. Now, I have checked that slic3r 1.2.6 has that problem fixed and was able to slice without problems.

I now want to skip the first 101 layers (starting height would also be known) and start printing with the remaining layers. I have examined the g-code but there are no direct z-axis movements and I wasn´t able to figure out which code is responsible for that.

I want to manually delete the first layers from the g-code file but exactly how can I see where the commands for layer 1 start and where layer 101 ends?


Somehow I managed to completely overlook that there are dedicated lines for z-movement. Those start with “G1 Z” and end with “F12000”.
Deleted the first layers and adapted the values for the remaining z-commands accordingly.
