I am about to configure a "System 45" 3 axis unit by DIYCNC in the UK , can some one please advice on what timing setting I should use when using the StepConf Wizard in LunuxCNC.
Also the instructions for the System 45 give the following setting for the drivers that I don't understand?

1/2 step type B (0-100%)
1/2 step type A (0-71-100%)

Which should I use?

Thanks

Steve
