MatterHackers / MatterSlice

MatterSlice is a C# console application that generates GCode (hardware control) for 3D printing. It was originally ported from CuraEngine (another great open source 3D printing engine). It is the primary slicing engine for MatterSlice and under constant development.

Given my limited understanding of G-code, this is the reason I ended up with a large coil of filament on my floor that escaped my extruder.

The G-code seems fine outside of that reset-then-large-extrusion.

If you need the actual G-code generated and/or the stl file used to generate, I can provide both. Let me know where to send them.

I'll comment with the bottom of the G-code file that lists the settings.

After looking at the numbers more, I suspect that what occurred is is attempted to retract 8mm (G1 E10109.36035) then it reset the extrusion amount (G92 E0), then it tried to extrude the amount retracted (presumably to get ready for printing) but didn't remember that it was 8mm and instead tried to get from 10109.36035 to 10117.36035.

Hope my interpretation makes sense and helps.

@RobotCaleb thanks for the detailed report. This has been fixed in development and will be in the next release. You can use it from Experimental now. Here are instructions to get it:

This version of MatterControl is to help get feedback on new features and ideas. It is intended only for testing and should not be considered reliable, stable or even working (from time to time).
