C-program questions- Dissallow into limits

[Scottburley]

First of all let me just say I have been really pleased with the kanalog/kflop boards that I purchased for my mill. I retrofitted an old motionmaster 5x5 3 axis mill that had analog drives and dc servos and it has been working wonderfully.

The pc that i've been using just bit the dust this morning, which I didn't expect. Of course I didn't document anything about the C-programs that I have written so I have to start from square one.

So here are my questions:

What should a start-up c-program contain besides axis parameters?

I have had difficulty getting the drives to re-enable an axis after limits have been pressed. The encoder position on kmotioncnc goes yellow. What would be the best way to write a c-program the board so I can reneable and drive out of the limit.

So those are my questions for now. Thank You

Hi Scott,

Ouch. Sorry to hear this.

The Initialize C Program usually performs the following:

#1 set axis parameters

#2 enables all axes

EnableAxisDest(0,0.0);
EnableAxisDest(1,0.0);
EnableAxisDest(2,0.0);

#3 defines Coordinated Motion Systems ie.

DefineCoordSystem(0,1,2,-1);

#4 anything else your system might need initialized

#5 loops to service any watchdog or MPG functions


Regarding disallow into limits: If your Limit options are configured to Dissallow Drive into Limits You should be able to initialize while in the limits as long as you don't move at all in the direction further into the limit. A different input is required for each end of travel.
