# Stagehand Apprentice 2 Parameters

There are a lot of parameters - just 1 mis-set parameter can cause countless hours of troubleshooting chaos.

The Stagehand Apprentice 2 includes a super cool new feature to restore parameters. With Spikemark 5 you can now load entire parameter sets directly from the [drive configuration window](https://docs.creativeconners.com/docs/spikemark/drive-communication/configuring-the-drive)!

In case you are interested to know what parameters do what on the E800 VFD, take a look at the list below for the stock parameters. The machine specific parameters are at the [bottom of the page](#stagehand-pro-2-machine-specific-parameters).
