Working on getting my MPG working with in Mach3 and have nailed it down to a conflict between the kflop plugin and pokeys plugin. I have also posted this in the Mach3/pokeys forum.

New Pokeys plugin MPG setup help.

Just seeing if there is something I can disable on the kflop side. The pokeys mfg is suggesting that the kflop may be over writing the mpg register.

I could run the MPG off the kflop/kanalog but would like to avoid having to run another wire from my panel to my main electrical box.

Thanks

Hi Wes,

I suspect that is a problem on our end. Rather than it being a matter of us overwriting anything, I think maybe our Plugin is supposed to read the Pokeys MPG position from somewhere and cause axes to move.

Normally an MPG is connected directly to KFLOP. This makes the response instantaneous. That is really the purpose of KFLOP to remove the real-time requirements from the PC/Windows/Mach3/Plugin.

I think for the trouble of adding another cable it will be well worth it to have better response.

Tom,

Been thinking about this today and was wondering if I would end up having a lag similar to the feed hold lag.

I well just run another wire. I have both a couple encoder inputs and general inputs. Does it matter which I use? I would think that the encoder one would work better.

Hi Wes,

I don't really understand the question about the feedhold lag. If you use KFLOP's hardware feedhold it will have guaranteed instant response just like the MPG.

Yes it is best to use a hardware encoder input if possible. I've attached a version of the MPGSmooth.c example modified to use a hardware encoder rather than the software technique.

Tom,

Sorry about not explaining myself better. I was just using the feedhold lag as an example of lag that I might have seen if I had run the MPG through pokeys instead of running it through kflop.

I have already looked into moving my feedhold button to kflop since there is a 2-3 sec delay before motion is stopped. Right now I have it run through pokeys. Going to have to run another wire for that one. I well be starting another thread with a couple question I have on that one later.

Thanks for the C program for the MPG I well be trying to get the MPG done this weekend.

Also thanks for the great support Tom.

NOTE: Not seeing the C program attachment on your last post. :-)
