Gcode looks odd - is that to cut just the outer circle? However, apart from a few rapid moves, it just looks like a set of circles. Used properly, Aspire is pretty solid so unlikely to generate wild code like that. Personally, my guess is that a coupling slipped or there was a similar mechanical issue. 100mm/sec is 6m/min which is pretty fast; depending on things like max acceleration this is going to put a fair load on the machine. But without more data, this is a guess!
