Having hired ER a $17.5k production CNC machine was diagnosed, electronic module built, and replaced. The manufacturer of the CNC wanted 900.00 for replacement. ER designed and built the replacement for $30.00. The CNC machine was up and running in a day. The $900.00 was passed onto ER for its ability to solve this problem in a timely manner with its available resource.
