Netfabb (on OS X + USB) is screaming and grinding my PLA!

Hi All,

I've just purchased Netfabb and I fear it's already causing me to regret it.

Printing from RepG and from the UltiController both work flawlessly, but once I switched to Netfabb... I get this

I'm really not sure what to do at this point.

You need to set M92 E14 at the top of the gcode file or as the default in the firmware.

I find it best to put it in the gcode so I can switch from netfabb to Cura as the slicer.

Click the "Machine" Tab, then "..." then click "Ultimaker specific" and in the Gcode Header put

M92 E14

Or switch netfabb into Volumetric mode, but I've not tried that as yet.

Thanks for the help.

Since netfabb decides to not update the mac version in any timely fashion, use the latest PC version to use proper volumetric extrusion (I haven't tried the new version yet, but hopefully it's better than the old, non-volumetric version that can turn your UM into a filament grinder).
