Hi,

We have a Larken router table that used to be running with a Larken Lcam controller and Cobra Stepper Drivers. We decided to undertake an upgrade of the Lcam unit to one a little newer supporting USB and some newer software.

We selected the controller from Planet-cnc as a starting point with the breakout board but we're having some problems.

Has anyone performed this upgrade or some similar that may have some insight to what's going on?

basically, everything is connected as we believe should be, the controller is sending step / dir signals to the best of our knowledge with out a scope.

It seems the motors are starting up locked once power is applied to the system and trying a manual key movement is not moving anything.

There is a faint whine out of the two larger 34D motors but that was there before the controller was changed out.

We're out of options for where / how to move the wires presently.

Any ideas?
