Problem initially highlighted at Roseview windows

* 100% VS slider sashes and cills.
* Very small selection of operations
* Parts are consistently the same
* Large quantity of 3mm spots
* Mechanically jointed sash can have up to 12 individual holes on one piece and over 5000 individual spots per day

</syntaxhighlight>This is a sample 449 code for a single piece. Each operation is a simple spot prep
<br />

* Spot prep spindle is regularly cycling on / off as quickly as possible.
* Overall cycle time very dependent on the cycle time of the 3mm spot prep
* Spot prep cycle determined by how fast the inverter can acc / dec
* Inverter Limits pushed
* Inverter faults, which slows the machine down 

Here is a video of a spot prep before optimisation. Notice the spindle has to switch on, accelerate, plunge, reverse then switch off and decelerate
