Configuring Plasmac - a complete THC/plasma config for any hardware

7I76, 7I76E and 7I76ED (and 7I77,7I84,7I70) inputs are all the same (sinking inputs)
You must apply field power to the inputs for them to change state.

The D option cards have sinking outputs instead of sourcing outputs, but the
inputs are the same as the non-D versions

Thanks, Peter I edited the previous post. It was much easier before you gave us more choices

I see now, I was thinking the numbering started over when it moved to the next TB#. Thanks guys

Well I'm not sure how I did it but I managed to get this to load without errors and jogging my motors. I'm starting to feel like I might actually cut something some day!

Thanks for your write up rodw and phillc54 and everyone else!

The OP showed an axis gui environment for the plasmac but I couldn't find that on my install today, I could only locate the gmmoccapy version. Is it just the one interface now? I'm not complaining at all I'm just curios, I imagine focusing efforts on one could be better anyway.

The pace of development is taking quite some time, mostly because I don't have a working machine and I am relying on others doing the testing.
Trying to support multiple GUI's at the same time was a bit too much.
Since John (the main tester) uses Gmoccapy I decided to keep only that config up to date.
To stop any confusion I removed the other GUI's from the repo.
When It looks like we have a reasonably stable and complete config I will bring Axis up to date, there will probably only be one version though, at this stage I am thinking the native version with the Statistics, Run and Config panels as tabs behind preview (the same as Gmoccapy)
That Axis version is actually the one I will be using if I ever get to finish my machine.

Cheers, Phill.

Its great to know people can install this now just by following these instructions!

I've made a note of the missing axis config in the earlier posts containing instructions. I also added an important bit I totally forgot about so as there are new users following along, I will add it again here:

Also its worth discussing these settings for the Z axis in the ini file which are specific to the external offsets Plasmac uses. I forgot to mention them earlier because I've been using them for so long. So MAX_VELOCITY and MAX_ACCELERATION should be double what your machine is capable of.
External offsets was designed that a percentage of velocity and acceleration was devoted to external offsets on the assumption that offsets would be applied while motion was occurring. In the case of plasma standard Z axis motion and external offset motion are mutually exclusive. You are either jogging around or you are cutting. So we want to devote 100% of velocity and acceleration to the Z axis while its under THC control. So by doubling your machine settings and applying a ratio of 0.5 (50%) we actually trick external offsets into using 100% of the axis machine settings for THC control. Cool hey! It did my head in working that out the first time.
