We're trying to use the G2/G3 commands with our 3D printer combined with a customer slicer. When you pass a G2/G3 without an extrusion rate they execute properly but without extruding anything (obviously). But when you add an E parameter the Smoothieboard freezes and stops executing.
So a line like this will cause it to freeze:
G3 X166.195 Y121.261 E0.306 I9.920 J7.301
Any help/suggestions on a fix?
