Slic3r failing to generate code

I’ve tried to use the Slic3r engine for a model and it kept failing to export repeatedly. I was using the default normal settings. Thinking it may have been an issue with model, I loaded a simple box .stl file 2" x 2" x 2" and Slic3r still failed using the default settings. The Cura engine is working and generated gcode. Is this a cloud issue or issue with the settings for my AirwolfHDx?

I have the same issue with Slic3R. It will not slice most of my models. Even a simple 1 X 2 X 0.25 inch rectangle cannot be sliced with AstroPrint using Slic3R. I too am using an AirWolf 3DHD. The Cura slicer works on these models but not the Slic3R slicer. If I use my PC stand alone Slic3R app it works fine, just will not slice on AstroPrint.

This seems to be something different. The problem is the start/end gcode that airwolf provides contains Cura variables in it.

Airwolf recommends Cura. If you change the slicer engine in your profile, I would recommend to also modify the start/end gcode to not include variables.

Let me know if this helps

Yes Daniel that was it.
The variable “F{travel_speed}” was the problem.
Slic3R does not like variables.
If you take out “F{travel_speed}” which is in a couple of places then the slicer completes successfully.

Thank you for all your help.
