While there would be  a bit of re-wiring to use a 7i96s natively, you could end up with a cleaner wiring if you had the room and possibly elimination of some relays etc.
I did help someone do this a long time ago and it was pretty simple. Took  a couple of hours including adding limit switches. Just make a very basic/rough config with pncconf and edit the STEP_SCALE in the ini  file so it is the same as Mach's stepsper value. 

20:1 eg 200 volt full scale is fine and gives a bit more accuracy but I have used 30:1 (300 volt full scale) on one plasma cutter which is also fine..
The thcads are rated for 500 volt over voltage and you will only exceed 200 volts when piercing when the THC is not active. If using halscope you will see that the voltage will flat line at the full scale before dropping back to the 120-130 volt cut voltage before the THC is enabled.

It may work with the N150. Apparently it has a new graphics driver which means you no longer need to use the i915 driver which is a good thing.
Another option might be the Odroid H4

If it is i915, there are some settings that you can disable. I covered them here:

Good luck

Thanks for your replyes. Yes, you right, i have to add this strings to xml config and every loading linuxcnc write electronic gear values to delta servo drive :

<slave idx="3" type="generic" vid="0x000001dd" pid="0x00006010" configPdos="true"> <!-- Axis Z -->
<sdoConfig idx="6093" subIdx="1">
<sdoDataRaw data="00 00 00 01"/> <!-- 01000000h= 16777216 P1.44-->
</sdoConfig>
<sdoConfig idx="6093" subIdx="2">
<sdoDataRaw data="d6 06"/>
</sdoConfig>
<dcConf assignActivate="300" sync0Cycle="*1" sync0Shift="0"/>

So long ago to remember but if you want to use gcode and gui buttons to do the same thing, I seem to remember you need to manage it in the python screen handler. Sorry I no longer have an example.

I have worked configuration for this, if it is actually question.
I connected aux encoder 1u resoluution to aux to drive. Connected it to hal by xml config, named linear-pos.
And change actual position to linear-pos. And its works.
About points to 1 rotation - i connected to drive, and calculate gear ratio, on my case it was 1.4 - you put electronic gear 1:1 and move 1 rotation of motor, and look at measurement "clocks" what is movement on mm. And calculate. Also coefficient in my case for linear aux was 7000 . There are manual from delta for calculation.
Also important point that i put in xml file in linuxcnc (lcec some.xml) electronic gear values, and every load of linuxcnc it download by ethercat .

Hi all. I've been playing with a design for a board that will allow me to read arc voltage with a Raspberry Pi. I think I've got something that will plausibly work. I'd appreciate a review of the attached schematic because circuit design is not my core competency.

Here's a quick tour:
1. Inputs are expected to be connected to the arc volt port of a blowback-start plasma power supply. 
2. Input voltage is limited to 250V by a TVS diode
3. Voltage is divided 50:1
4. RCRC filter limits frequency to 14Hz
5. Raspberry Pi reads divided voltage via ADC

Thanks!

I have a Lorch plama cutter that ignites with hf....

By me was it the monitor cable ...

JT, hi. Its me again for today)

I have Cnc machine with axis - xyz and C. (C because it is rotated around Z axis).
when im powerup the machine and starting jogging it, i have to use axis C as axis for jog number 3 - jog_plus_pb_3. But after homing  that axis became axis number 5. And after homing i have to use jog_plus_pb_5.

It is strange, and i found only that i could block jogging button for C axis until homing is conpleted. Is there any more flex solutolions for this issue?)

Thanks in advance!

Hi, JT!

i didnt understand how to add functionallity, to doplicate fleglxgui buttons like a PowerPB and Reset (included functions, and there are not in Hal components) to the external hard electrical contacf buttons (ext btn already in hal, but where the pin signals to connect it)?

Thanks in advace!

I tried it as you said but nothing changed.
Again receving "USRMOT: ERROR: command timeout" errors and couldnt control the LEDs.

 

    "rpi5": "true",
->
    "rpi5": true,


 

Thats the trick, thank you.
Its working now... 
 

Seems to all be working correctly open to any additional inputs
