Re: Axis moving wrong direction from file

Turns out that the issue is with the programmed feedrate of F1.5 in G99, which is feed per revolution. A value that high is more of a value is more of a feedrate for feed per minute or G98 moves. A fix would be to either replace the G99 with a G98 or have the feedrate set to something like 0.001 ra...

Re: Analog 0-10 volt staying at .6 volts when should be zero - RESOLVED

After doing some further testing ,you can not use a relay to try and control the spindle fwd on the dyn 4 drive because if you disconnect the analog circuit by a relay you get servo runaway. I believe we are sunk as Clay said until Dmm Tech sends the new drives out and hopefully they have fully test...
