output for smooth stepper
« on: February 18, 2009, 01:54:03 PM »
Bread boarding a smooth stepper,, First the things working,, X axis signals pin 2 and 3  fine, spindle signals pin 4 and 5 Good, both set to port 1.  Input good, oem triggers working, inputs on port 1.  Now the bad,, no output signals,, none,, even when I change the active low setting the pins has no response, my outputs are enabled and set to Port 1.. whats up any ideas ??

I and using a handy c11 Multifunction brakeout board from cnc4pc.

thanks
Josh

I am progressing slowly,, I changed the state my output pins are in to active low and hit apply and OK and there condition changed,, IE my LEDS lit up :)
So my smooth stepper is working the outputs, but is ignoring them in my Gcode?? I feel like I am missing an enable button some where

still working

You should be aware the CNC4PC C11 does NOT work well with the SmoothStepper.  That *may* be your problem.  Clearly Mach can "talk" to the outputs, and the SS is doing what it's told under "static" conditions.  The C11 contains filters on the Step/Dir lines which, due to their design, can filter out the step pulses from the SS.  I would expect it to work at least at low speed, but who knows....  I had to modify my C11 to make it work with my SS.  You should probably call Arturo at CNC4PC.

Thanks for the post Ray,,
So you think the board is ignoring my M11 P4, M11 P9, output commands?,, could it be the bleed down resistors?

thanks

They are custom macros? if so that may be your problem as macros under 100 are reserved for Mach use. To be honest I have used custom macros under 100 and not had a problem but maybe the ones you are using are being used internally.

I have no custom macros, all the commands IE outputs on Outputs off I got of your wiki?  My system works ok with PP port exept for the loss of some steps here and there,, that being the reason I am trying out a SS

Have you set up a new profile for the SS? If you have then check that the M10 and M11 macros are there and that the content of them is correct.
