Does anyone here have experience using "O Drive" for a machine tool application? These were designed for use with robotics but it looks like they are ideal for a high-performance milling machine. It is Open-source. The firmware and hardware schematics are on GitHub.
https://odriverobotics.com These drive common and cheap three-phase brushless motors using shaft encoders and any of several inputs like step/dir, CAN, analog, USB or serial. Power is up to 56 volts and over 100 amps peak. $150 for a two-axis controller. They can be drop-in replacements for stepper motors but can also do much more. A PID loop runs inside this controller so you can set the velocity over the interface or just send step/dir and know that the internal feedback will make sure no steps are skipped. -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
