Hello Everyone,

I'm Joe. I'm kinda new here :)

I'm working on a CNC Router in my free time. I have read many posts about using an Encoder along with a Stepper motor. However I'm confused as to how to get it done. I do not intend to obtain a Closed loop Stepper Drive system (which many said is almost impossible to do - Plz correct me if I'm wrong here!). All i want is The machine to Pause/Stop Execution when the Motor stalls or misses steps. I have read it is quite possible using EMC2. I have been searching various topics and doing a lot of reading over here but I couldn't find info as to how exactly to configure it.

Hope someone can help me with the configuration steps or point me to a thread where configuring Encoders with Steppers is discussed.

Thank You!


Joe!

Hi Joe,

There is some info on the wiki site on steppers with encoders.

wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Steppers_With_Encoders

I think you would have to close the loop to stop with a following error from a stalled stepper.
