The 1.8 degree stepper motors arrived today. As I understand it, these are for use in the extruder and the z-axis. The 0.9 degree steppers are for the arms. With no 1/32 microstepping drivers I will be sacrificing resolution, but the drivers are plug and play so I can always upgrade the resolution later.
Last night I also measured out all the holes on the top platform. The dxf file shows arc-shaped slots on one side, and it seems that there were one or two machines (found some online photos) with fans blowing on the bed. I have ignored these slots for the moment, I can always add a fan later if necessary.
