Thank you, guys, for suggestions! Problem solved! I decided to take motor apart and see, if I can find something. And I did find something - small scratches in 2 spots on encoder disc. To verify that this is the cause of problem I swapped encoder discs with the motor on the other end of gantry bridge. And best part of the story is that both motors work correctly! Ordering new replacement encoder is on the to-do list, but it works now just as it is. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
