General Mach Discussion / Mach and Closed Loop DRO Operation

« on: May 18, 2015, 02:44:21 PM »

Does either Mach3 or Mach4 have the ability to monitor the output of servo or stepper shaft encoders in order to better assure axis positional accuracy and motion control?

If not, is it correct that the Mach DRO displays operate on the basis of Mach commands rather than rely on feedback directly from the machine being controlled?

General Mach Discussion / Chinese Digital Caliper As Encoder?

« on: February 17, 2010, 02:05:21 PM »

Just wondering if Mach can use either the direct or modified output from the inexpensive Chinese digital calipers in a closed loop manner to help resolve backlash and other positioning errors??

It's my understanding that the Chinese calipers don't output the same quad signals that are standard on most encoders.
