I'll try this. Thanks > 2.

We have played extensively with this, but it is the other parameters I was looking to change. Ferror, Acceleration, max velocity etc. I'll try the halcmd -kf" How do I change the default loaded Gcode program ? ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
