APPENDICES
A1. COMMON DRIVER JUMPER TABLES
These tables are provided as a convenience to the user. Since we cannot speak on behalf
of the manufacturer of your drivers it is recommended that you still find the datasheet for
your drivers and reference the pin settings required for the microstepping factor that you
desire. Note that the pin naming and ordering in the tables below is not consistent but the
lowest number pin will always map to the pin named MS1 on the octopus and the
numbering follows from there.
