Title: MPG Setup ????
Post by: Cbyrdtopper on May 15, 2015, 09:25:56 AM

I have an MPG that I want to work with Mach 4.  I am using an Ethernet Smooth Stepper (ESS).  Under the ESS I/O configuration, I have my 2 input pins set to MPG/Enc 0-A and MPG/Enc 0-B.  From there I do not know what I need to do to get axis movement.  Eventually I will have a pendant for the machine so I can set up in the PLC script the inputs for axis selection and jogging speed/mode.  But for now I need to know just how to get movement via MPG wheel.

I know Greg had plans for adding MPG support to the ESS but I am not sure if he has yet. You may want to ask him.

In Mach 4 configuration do I need to do anything to setup the MPG?  That's more along the lines of what I was asking, sorry.  I haven't seen anything in Mach 4 that does anything to do with reading inputs from the MPG.

I have the MPG wheel working with the ESS...

Just trying to get some feedback from Brian B before I post it to the forum.

Look at this post...Jogging/Pendant Interface-What is the best way? Ramblings ... I put some code there.  You can get an MPG working.

Thanks TimGS!  I'll give it a look.  I'll be able to do some testing when I'm finished with a machine I'm working on.  I really want to get Mach 4 put on it.  Still have a little ways to go to get an understanding of Mach 4 and especially Lua.

Yes it does....Lua is kind of nice loose language.  If you know c/c++ you will be able to figure it out.  There is also a lot of online Lua manuals...just Google Lua.

One other note:  Don't forget to configure the MPG connections to the ESS within the Plugin ESS configuration inputs.  The names are predefined by the ESS Plugin; you will find them in the pulldown.  You only need to use the MPG part of the script code that I wrote.  You can use the <Jog Cycle Inc> button on the screen to control the MPG increment.  You might have to change the MPG Counts per increment in the script; mine was equal to 4.  Look under the defaults in the beginning part of the script.
