A client's existing stepper motor control system, re-engineered for precision, stability, and responsiveness — with an LCD control interface for direct operation. See it running in the video below.
The client had a working stepper motor setup that wasn't good enough: motion was imprecise, unstable under load, and slow to respond to control inputs. Rather than replacing hardware, we re-engineered the control firmware — often the highest-leverage fix in motion systems.
The upgraded system drives a NEMA-class stepper through a dedicated driver stage, with an LCD panel and rotary control for direct hands-on operation — no PC required at the machine.
The client called the upgrade "a significant improvement to the overall project" and rated the work five stars.
★★★★★"The Arduino Programming for Stepper Motor Control Upgrade was implemented exceptionally well and represents a significant improvement to the overall project. The upgrade greatly enhanced the precision, stability, and responsiveness."
