When I setup for a new print, filament already loaded in, I whish I could extrude some cm of filament just to make sure the flow is clean.
I' don't find in the menu any command to get some extrusion without changing filament.

Any guess?

Got it!

G21 is to blame.

I'll rewrite my startup sequence.

Thanks William, Here you can find the first part of the crashing code, I have a small video but I can't post it here (extention type...) Removing lines from 3 to 6 makes everything work. ;Generated with Cura_SteamEngine 15.04.5 M109 S210.0 G28 G21 G90 G92 E0 ;Layer count: 76 ;LAYER:0 M107 G0 F9000 X...

Does anyone knows why this common setup sequence gets my E180 mad?
The printer beeps and stops without printing when it receive this:

... then comes the printing code...

Thanks!
