i get this error after git pull to 7a51831cb4dc6b2ae56ad24400ba1fdfed064528 when trying to export g-code regardless of .stl file used The .stl and config files used to work before update

this happends when autocooling is enabled also setiing pressure advance in printer settings gives : Use of uninitialized value in multiplication (*) Slic3r/lib/Slic3r/GCode/PressureRegulator.pm line 46

i'm sorry for the long delay, but i've been busy (and hoping it will get fixed anyway ;-( ) now i'm back and found a little more about it the issue is still present in 5eb3bc52efa807c0439dba1ec0971fc37850d51e, it appeares in my case when using a specific print settings file on any object that has infill generated (this explains why the 1 milimeter cube is working) and auto cooling is checked. i did not attempted to generate raft layers i came with this file because i was using a config file that came with the printer and playing with various settings starting with the defaults and editing settings results in a configuration that works

any ideea on how to identify the specific parameter ? anything i changed from the interface so far did not affected the issue

to me it looks that Slic3r::GCode::_extrude_path is called with an undefined parameter (speed) because Slic3r::GCode::extrude_path is called with only three parameters but then i'm lost

this is the offending file:

@mihai9, I tested your last config with a 20mm cube and I got no crash so this looks fixed. Let me know if this is not the case. Thank you for reporting the issue.

pcarew commented 7 years ago

I had this issue on Ver 1.1.7 I resolved it by changing 'First Layer Speed" I had inadvertently set it to '0'. I changed it to 30% and problem went away.
