I think I have it working with decimals now.  All of the tests I did showed good results.  But I had to change a lot of code and I might have missed a path or two.  It will be in the next release.

PMC was never meant to handle decimals as most PLCs don't have decimal registers.  :(  I'll see what it takes to put that in but it may not be trivial at all.  It will not handle strings either, FYI.

In other words, if you are going to probe, you must dedicate at least inputs 1, 2, and 3 to the probe.  If some other switch is tickling ANY of those inputs, it will be seen as a probe latch.  Not too good!  So please un-wire anything connected to inputs 1 and 2 (X and Y latches) and if you are going to do that, you might as well wire the  probe to all 3 of them.  Remember to wire in input 4 if you have A axis enable in Mach too!

Correct, the plugin handles AL and RL.  But understand that the plugin will do an AL for every axis it controls.  So you really need to wire the probe to all three of the latch inputs if you have X, Y, and Z axes enabled in Mach, regardless if you will only be doing Z probe moves.  If A axis is enabled in Mach, then wire in input 4 as well.

In order to use a Galil, one must understand how the Galil works.  The plugin documentation assumes that the user is familiar with the Galil and we don't try to teach or document Galil aspects that are in the Galil documentation.  You can't simply hook up a Galil and run the plugin and it magically work.  This is because the Galil has its' own motion planner and can be used as a stand alone motion controller.  It is not a "dumb" controller like a parallel port or some other step generator motion device.  This makes it more complicated to setup, but the end result is worth it.  

The latch inputs are a Galil term.  Look at the Galil operator's manual and command reference (AL and RL) and read up on the latch inputs.  There is one latch input per Galil axis.  You need to wire the probe to all of the latch inputs that from which you wish to get a position.  For a 3 axis mill, that would be X, Y, and Z, meaning Galil input 1, 2, and 3.  Galil Input 6 is not going to cut it.  :(

Since the probe will be wired to multiple inputs, simply pick one of those inputs and map it to Mach's probe signal.  Mach only has one probe signal and it is NOT used to capture the the positions.  The Galil does that via AL and RL.  However the Mach probe signal is used to prevent a probe move if it thinks the probe is activated.  If the probe is not activated and Mach thinks it is, simply check or uncheck the Mach digitize "active low" setting until the signal agrees with the actual state of the probe.

Probably not until after IMTS.  :(

The SAFE thing to do is use a general availability release from the main page.  :)  ANY of them from the development ftp site are likely to be bleeding edge.

Well...  that is hard to say.  Maybe by week's end?  I'm working on jogging during feed hold and it is a complex issue.  :(

Arturo,

I added the encoder registers in the list of input registers for the PMC.  So the next build will have that in there.  However, I really don't think the PMC is the proper place for it.  That sounds like something the motion controller plugin should be doing.

Arturo,

At this time, encoder registers are not included in the list of input registers.  But are you needing an encoder value in the PMC?  To drive an MPG?  If so, you can associate an encoder to a MPG object in the Mach config.
