Does the stepper control system sometimes lose steps?
• Proper engineering of a stepper system is not trivial. The fact that stepper driven motion control is commonly used on mission critical systems, such as medical equipment, is testament to the reliability and accuracy of the technology. The technology has been given a black eye by a few poorly design machines offered by others, as well as a large number of hobbyist CNC projects. A proper engineered machine, like the PCNC 1100, will not lose position in normal operation. The PCNC 1100 axis system can deliver 850 lbs of force before missing a step, more than enough to break most cutting tools. Step loss has simply not been an issue for us.
