Mach + Grex + Pendant w/MPG
« on: July 19, 2006, 05:54:21 PM »
I love the Grex/G100, but one thing I have found hard to adjust to is the delay in axis movement when jogging from the keyboard in Mach.
I am wanting to build a pendant with MPG control (encoder wheel), axis select (X, Y, Z, A), and distance set (1, 0.1, 0.01, 0.001).

I am not sure if the current Mach3/4 (Grex firmware?) will support this, since the pendant will be using inputs on the Grex.
I would assume the pendant controls should directly drive the Grex, otherwise if the inputs from the Grex are fed to Mach, which then will try to step the Grex.. I would be back where I started with the delays in jogging axis movement, correct?

Anyone have any information on doing this?
Thanks-
Colin

I had been running Mach4, and have been advised to try Mach3 1.90.065 with the G100 plugin.
I did that and the axis responce to jogging is SOO much better!!
An MPG/Pendant would stil be nice, but for now I can live with this.

I have an MPG hooked up to the Grex here on my desk... I will have to look at the code and see if I can get it working :)

You need to put it on an Axis encoder and it should work.. I have not taken one out to my mill ... I need a bit more time!

You don't need to have the ports and pins set up.. I just had it hooked to the X axis encoder... I know it was loading the values into mach3 butI never jogged the mill with it :(

we are goign to need new firmware becasue the old stuff that is in there now is only sending the data every 1/4th of a sec

So you connected an extra incoder to the A and B incoder inputs on the G100 and could jog?  The G100 has incoder inputs I, A and B so maybe you connected to something other them B else I got something still wrong..  When I connect to A and B I can get the LED's on the G100 to blink and everything but no movement from the machine.  Maybe try connecting it up again or something else I'm missing..

Art may not have turned on the MPG code in Mach3 for the G100 :(  I hear there is new firmware, it is not ready for release but it is getting there! So I we will work more on it after it is done. all the code that is making it work now is going away and all new has to be made :( (I think Steve is doing that too :) )
