Do you need to activate them from gcode or from GUI?
Why 7i73? See 7i71 or 7i72 at 48 outputs each.
Not much info to go on, but yes LinuxCNC should have no problems controlling "as many as you can wire in" outputs, granted the hardware is there.
But that will also depend of the first question.

I need to setup a machine that will require 200 custom outputs.  I was looking at using Mesa cards since I am familiar with them and they will allow me to control that many outputs using a 7i74 and a bunch of 7i73 cards.  Will LinuxCNC allow that many custom commands?  If so, how would I approach this? I am familiar with the M100-M199 User Defined Commands, is there a way to add more beyond M199?

I don't see anything in the hal  files that reference the THC or plasma voltage or

I see no one is interested... But I did it for myself, so I'll share it.
I decided to change github.com/andypugh/LatheMacros/tree/Py3_GTK3 because it contains errors and is dangerous.
In short, the author used the modal codes g95 and g96, which is fine, but he did not cancel them at the end of the subroutine.
After completing the cycle, LinuxCNC remains with active G95 and G96 codes, and believe me, 100 mm/min and 100 mm/rev are not the same and making a move in MDI, for example, may end in a disaster.
Since the archive contains a very large LatheMacro.svg file and I wanted to keep everything as a whole, I had to cut the tbz archive into smaller pieces so that I could post them here as attachments.
You cannot unpack these files normally, you have to do it like this:

I do not really understand why,
but when i load the usb-mpg via Vendorkey+Productkey and -K option, all works fine.

Any disadvantages loading the keyboard via vendor/productkey and not via name?

Greets, Tom

Thank you!

Sorry, typo,
this is what i wrote.. 
At least in halrun this is not going to work.. Am i right that what does not work in halrun will not work in the halfile?

 
 

7i92t_7i77_7i76d.bin is fine for a 7I92T + 7I77 / 7I76U setup.

The only case where 7I76U specific FPGA firmware is needed
is when you want to use the  7I76U's serial port in RS-485 mode
(say for Modbus), but even if you need Modbus, you could use the
7I77s serial port (that natively supports RS-485)  for that.
 

THC is enabled in the GUI and mesh mode is turned off

left the config attached in case it might be of any use

Hi, I'm building a plasma table (QtPlasmaC, THCAD-300) around a 7I80HD-T and would like to run the ST8_PLASMA config — 8 stepgens plus the two encoder inputs is exactly the right fit for this machine.

I see PIN_ST8_PLASMA_72.vhd ships in the 7i80hdt.zip hostmot2 source, but there's no prebuilt 7i80hdt_st8_plasma.bin among the stock configs, looks like it was only ever built for the Spartan 7I80HD.

Any chance of getting a Trion build of that config a test. If it's easier to point me at the Efinity project setup to build it myself, that works too.

Thanks!

I am not moving to USA !!! It has become unbearable, even on TV !
Sorry for hijacking the topic.

Moved to "driver boards".

coming from Heidenhain i can just move in one axis including RL/RR (Heidenhain cutter compensation) and the tool will move in one axis as well but it seems like linuxcnc doesnt move in one axis but two. If there is not much space but i need to use cutter comp, then i move to the starting point of the entry radius with 5% distance of the endmill and the entry radius is 5% bigger than the endmill as well and this works flawlessly with Heidenhain.

attached images: 
1: starting point. Circle is cutter, green line is entry move and blue line is contour to cut.
2: moving straight to the starting point of the entry radius then continuing moving along the entry radius.
3: this is what i believe linuxcnc does, it moves the tool to the left completely through the entry radius

is there anything i can do to achieve what i can with Heidenhain? (can this be hacked?)

How would you do this?

The exit move is exactly the same (though mirrored) but linuxcnc doesnt have an issue with that.
