PM25 BLDC spindle drive replacement from Anaheim Automation

A BLDC drive from Anaheim Automation is tested as a replacement to stock spindle drive of the PM25 mill. The stock drive is not documented, lacks a fault signal, and responses slowly to direction and speed changes limiting rigid tapping. The Anaheim Automation MDC300-120151 drive has advantages but with the…


Closed-loop stepper motor following-error monitoring

A program is presented for extracting and plotting following-error of Leadshine Easy Servo closed-loop stepper motors. This building-block will help us explore if integrating machine status into LinuxCNC might help performance of a CNC milling machine. This is video is part of a series.

Make a Heatsink for Stepper-Servo Motor Drives

While organizing the electronics for a CNC conversion, plates are made to hold functional units that can be moved along DIN rails. One of these is a plate to hold all the drives for the stepper-servo motors (Leadshine ES-D508 Easy Servo drives). A plate that also serves as a heatsink…
