Hi Tom,
A little update on our trouble shooting status:
We installed amp meters and volt meters and everything from the Kanalog out to the laser appears to be working properly.
I started messing around with the settings in the KmotionCNC.
Before with all of the advice you had given we had steady motion but little to no variation in the DAC output.
I went into the Trajectory Planner Menu in KmotionCNC and changed the C Axis "Radius Inch" value from zero to different values (the box after the Degrees check box) and the DAC reading started to really jump around but we ran into the same issue as before where it's not a continuous motion in the X & Y (there is some slowing down) but the laser is going from high to low very quickly. The best setting is 0.1 for the Radius inch box that we have gotten to work there is still some slowing of the drive axis but we are getting an image that is recognizable. But about 1/4 way through the drawing the laser motion comes to a crawl.
Is there something else that we didn't think about in the Trajectory settings which was causing the C Axis to drive very slow during coordinated motion?
There will be a video headed your way when we finally get this ting working.
Thanks Again
Dan
