General Mach Discussion / Re: Rotational Soft Limits on A axis, once more, cannot be disabled.

short update from here.
Tested some things and as Hood says no problems here in .062 and Printer Port but still problems by using the SmoothStepper
so it is the SS Plugin with the glitch.

Hi all,
sorry when I enter this thread.
So far as I remember there is still a glitch in Mach and rotational Soft Limits.
I think that was discussed before in the forum. I put in  +-999999999999 in Homing/Limits for the A axis and its fine.
Note that Mach is counting and saving the G53 position when the axis is not referenced. You may reach the limit one day.
Just a thought.

PoKeys / Re: Two buttons doing same thing, possible?

can it be that your buttons are not momentary switches ?

ah ok,

in this case try

Pin***   --> Function= Input --> LED = none --> Button = 307 push to jog X++  --> inverted
Pin***   --> Function= Input --> LED = none --> Button = 308 push to jog X--    --> inverted
Pin***   --> Function= Input --> LED = none --> Button = 309 push to jog Y++  --> inverted
Pin***   --> Function= Input --> LED = none --> Button = 310 push to jog Y--    --> inverted
Pin***   --> Function= Input --> LED = none --> Button = 311 push to jog Z++  --> inverted
Pin***   --> Function= Input --> LED = none --> Button = 312 push to jog Z--    --> inverted
 
is working here

Glad you got it so far
to see if is something wrong in your Pokeys settings regarding the Single Block just save your actual Pokeys settings ( XML file)
then use the default XML file from Polabs website and see if it works correctly. If so you can compare the settings.
Unfortunetly I can't load the  kbd48cnc XML file without a  kbd48cnc connected to the Pokeys so can't help with the
jogging problem. Only thing I can do from here is if you assingn all buttons ( jog +- and axis select) to an Userled then it could
be done with a brain. But first explore if there is a setting for what you need in Pokeys setup for the Jog Buttons.
maybe you can attach a screenshot.

Russ,

go to pokeys plugin configuration. -->  kbd48cnc-->
CycleStart  --> Function= Key --> LED = 1990 --> Button = none   ( maybe inverted can't see it here )
FeedHold    --> Function= Key --> LED = 1992 --> Button = none   ( maybe inverted can't see it here )

Pin***   --> Function= Input --> LED = 1991 --> Button = none --> inverted      ( external Cycle Start button )
Pin***   --> Function= Input --> LED = 1993 --> Button = none --> inverted      ( external Feed Hold button )


is working fine here so far, accept I have no  kbd48cnc.

see pict. of the brain I used

Sounds a bit you using an external controller, can it handle the backlash compensation correct ?

just a thougt

VB and the development of wizards / Re: encoder dro with m/c dro Comparison

« on: December 23, 2013, 01:44:48 PM »

I assume you want it for a kind of safty, if something fails to e stop the system.
a kind of closed loop isn't possible with a brain ( or macro ) not even close to.

the brain runs fix at 10HZ  so 100ms for one run.

that means you have a lag of 1mm at 600mm feedrate or 10mm at 6000mm feedrate and so on.

plus the lag time of the incoming pulses what is small compared to the brain.

Ok, in this case I would say yes. You said you get nice results at half rapid speed then reducing the encoder resolution ( PPR) should work.
But as TP said your system will have lot of work to read the inputs.
For that I would choose the lowest encoder resolution where you can live with lets say 400 PPR or lower.
