Problems with Lucy

[CrazeUK]

So I finally have Lucy set up and read to go.

Yesterday i was doing some test cuts on some 10mm foam board i had readily available.

I quickly drew up a file with 6 circles that sit within each other, and for the CNC to cut various steps into the foam board, then finally cut the circle out of the board.

Circle	Depth	Radius
Circle 6	8mm	20mm
Circle 5	6mm	40mm
Circle 4	4mm	60mm
Circle 3	2mm	80mm
Circle 2	1mm	100mm
Circle 1	11mm	120mm

Should look like this:




See the attached Aspire file, dxf and file for Mach3 txt file: CNC Test-20170304.zip

I set the feed rate to 100 mm/sec and 8,000 RPM

Anyway, everything looked file until it got to the outer circle (circle 1), when it did this (I set it to do 11mm, so all the way through)!




Does anyone have any ideas why it did such a crazy thing?
