Kindly please help me to figure out the following generic situation:
a simple router with steppers, Kflop and closed loop with glass scales. For
simplicity, I will use for length measurement microsteps.
Lets presume that the glass scale have 5 microsteps resolution, the mechanical
backlash is 50 microsteps and the movement is made in 1 microsteps increments.
The desired level of accurate positioning is 10 microsteps.
What I am aware is that I left out as input infos the inertia and the cutting forces.
Based on real life examples, within a range of weights, speeds and forces involved,
what do you predict in terms of reducing the effect of backlash (if possible) and also please comment the relation between backlash , desired accuracy and scale resolution
Thanks,
Adrian
