Closed-loop stepper motor following-error monitoring

Closed-loop stepper motor following-error monitoring

Could we improve the performance of do-it-yourself CNC machines by integrating machine status into the CNC controller. In this video we’ll read the following-error from closed-loop stepper motors into the computer running the CNC controller. Other videos in this series will build on this idea. The use of stepper motors on CNC machines is criticized …

Mysteriously Faulting Stepper Motor, Closed-loop

Mysteriously Faulting Stepper Motor, Closed-loop

Hi everyone, welcome back. My name is Kent, and today, we’ll look at a problem that I had with my CNC mill conversion [Precision Matthews PM25]. Despite their relatively small size, I’m successfully using 280 oz-in NEMA 23 closed-loop three-phase stepper motors. [Leadshine ES-M32320] Being closed-loop, the driver knows if the motor is out of …

Make Heatsink For Stepper-Servo Motor Drive

Hi everyone, and welcome back. To get my CNC mill operating quickly, the mechanics received more attention than the electronics. I’ve been slowly reorganizing the wiring to make testing new hardware easier and to prepare for moving electronics to an enclosure. To make moving components easier, I’ve mounted functional units to plates that are then …

#6 Installing Stepper Motors and Programming VFD #6 / C-Beam Lead Screw CNC

In the previous videos I completed assembling the x, y and z axis of the lead screw CNC machine, and in this video I will attach and wire the stepper motors, fit a sub waste-board and correctly wire and programme a variable frequency drive to power the 1.5kw water-cooled spindle. If for any reason you …
