Hi,

Iam building a DIY CNC router using stepper motors.

1) My first doubt is whether to microstep or to halfstep or full-step.
I have a micro-stepping drive. But not sure about the pros&cons of microstepping vs FullStepping.
Is microstepping really reliable in terms of positioning accuracy, particularly when there is router load?

2) My stepper drive has option of lowering the current to half , when it is not receiving pulses i.e. idle.
Should I use this feature or not? This feature is ON by default. But say Iam cutting a rectangle, when Iam doing X-move, Y-axis will be idle and so will be at half the torque. Is this advisable?

regards
