Re: Micro-stepping low cost steppers...

Very true, the can steppers are a great bang for your buck, and although there are other advantages to microstepping an inexpensive stepper, the extra resolution you gain will not be very accurate.

Micro-stepping low cost steppers...

Low cost steppers also do not have well controlled coild positions, as such, the quadrature modulation of the coils does not produce the expected angular results.

Scientific grade steppers are needed for very precise angular control when microstepping very small angles.

Ramp Tables

Another consideration worth mentioning is the use of ramp tables to drive stepper motors.  In certain applications, depending upon motor type, performance requirements, loading and operating speed, ramp tables are used to gradually 'ramp' up from a slower speed to the faster speed.  This helps prevent the motor from stalling as it goes up to the faster speeds (which typically have different torque values than the slower speeds).

As additive manufacturing (including 3D printing) becomes increasingly popular among businesses as a quick and easy solution to creating and evaluating prototypes and end-use products, the debate about whether to outsource production or to purchase equipment for in-house use is at the forefront of industry discussions.
With increasing terrorist threats overseas, organizations are thinking about how best to defend themselves here and abroad. Engineering can play a role, especially when it comes to putting a barrier between yourself and the bad guys.
Time to market is everything, but at the same time, you cant sacrifice quality for speed. Thats where additive manufacturing comes into play.
In the last few years, use of CFD in building design has increased manifolds. Computational fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
