This should work for 2.8 and up, notice the hal command at the end for refreshing the Gremlin (plotter).

Not sure where you got that information from but I don't see an 'axisui.refresh' pin:

 

i did some rework on the mounting for my air cylinders and have been getting stuff gathered and sorted for driving this chuck while i have been working on the clamping needs for soft jaws for this thing. i did some testing to see how good things will center and with out to much effort i looks like things will at least be within .015 off center at the worst 90 degrees from the air cylinders. centering and around .005 off in the line of the two air cylinders. so things look promising so far.

I'm not sure what would realistic since stock tubing is not going to be perfect to begin with but i have one last thing to try to see if i can get things in line better to get as good as i can get and produce repeatable results every time. If i can get within .005 of center all the way around i don't think it's going to get much better than that or at least on a repeatable level.

accurate clamping and centering will open up better options for programming a rotary, so this is my end game. i also think once you add a second chuck that will help quite a bit as well.

Good evening all

I was really holding off on asking for help as i much prefer to figure things out for myself but i'm running up against a few specific struggles and i'm starting to get the feeling that i'm just missing something that perhaps you experienced folk may know about due to experience. 

I have setup a nice pc with Linux Mint 22.1 using the ISO Tommylight provides. the LinuxCNC included in this was 2.1 which seems old and this is however the first detail i might be missing the mark on, in hindsight 2.1 seems to old to be logical so perhaps its a different variant? Regardless, i uninstalled that and installed 2.9.4 which went without a hitch, but did not make anything work any better. 

I then came across MesaCT as pnfconf doesnt support this card. I set the card jumpers as per instructions in MesaCT and i can ping it on 10.10.10.10 but i cannot connect to it.

MesaCT reports that the LinuxCNC version is "version error" - my gut feeling is that the linuxcnc version is newer than the latest update for mesaCT and its just not able to report on it correctly - can anyone confirm if this is preventing operation?

Finally, the detail that i believe is actually stopping MesaCT connecting to the 7i97T - the mesaflash version is reporting (correctly) as 3.4.6, MesaCT notes that for the 7i97T connect, Mesaflash 3.5.3 is required, however i cannot for the life of me find where this is to be obtained, or even any reference to a mesaflash above 3.4.6 other than a few posts on this forum where users mention they are setup with 3.5.x and don't seem to suggest that this was at all difficult. Those posts were all a couple of years ago, has something changed with the version numbering? 

I am not at all new to computers but i dont have a large amount of experience with linux, happy to do the learning but it looks like i need a swift kick in the correct direction! 

Any help greatly appreciated

p.s. i couldnt decide if this should go under "installing" or "general" apologies if i picked wrong.
