Thanks.

I soldered both resistors in the + und - Line inside the plasma source and also connected the 2 torch-start pins of the plasma-source with the Spindle enable + and Spindle enable - -Pin of the Mesa 7i76e-board.

When I power up the plasmacutter it instantly fires although the torch is not activated in plasmac. When I remove the 2 wires from spindle enable +- then the plasmacutter doesn't start when powered up.

When I measure between s-en+ and e-en- with a multimeter there is no connection but the plasma fires when started. Maybe somebody has an idea ? Do I need an additional relays ? With the hypertherm powermax 1000 G3 on the same mesa-card this didn't happen ?

Maybe sb has an Idea?

I would first verify that you have the correct firmware installed
in the 7I92T (7i92t_7i76x2d).

Next, I would verify the hardware by setting the 7I76 index input
mode to TTL mode (W4 left), unplug the encoder, then watch
the signal hm2_7i92.0.encoder.00.input-index in halshow
and check that it changes state when you ground the IDX+ input
(TB3 pin 13)

Hi,
I am new here, just rebuild an existing router and swapped the old electronics out for a mesa 7i96s with linuxcnc 2.9.4. everything went smooth except one thing.
The old router configuration had a single home sensor for a dual gantry. So i added an extra sensor for the second driver to be able to home. The problem is that it is impossible for me to add the sensor at the exact right spot (both are on opposite side of the machine.) So i managed to get the sensors roughly at the same spot (within 1mm) Now i would want to put the gantry manually square before powering up (it is a very sturdy bridge which automatically squares out if run by hand) and then i would like to power up the machine and jog incrementally up to the sensors. with the hal watch i could see which one lights up first and i could also check how much extra jogs i have to make to light up the other sensor. this would give me the offset i need to square out the bridge with homing. Now i am forcing the gantry out of square with the error in my sensor placement
SO here my queation: Is there a way to force linuxcnc to jog both joints simultaneous before homing

I'm beginning to wonder if it's getting speed signal or worse this encoder can't read in reverse. If it doesn't get speed feed back, it has nothing to hold it to so it just defaults to a set number. At least this is my reasoning thus far.

Hi Guys,Recently I had my 5i25 card fail and bought a 7i92TM to replace it, updating my HAL file to suit the new ethernet board.
LinuxCNC runs as normal, however, the spindle index pulse is no longer being recognised. The index pulse was detected and rigid tapping worked when I had th 5i25 card installed. I have not made any changes to the HAL file in regards to the encoder.

I confirmed with an oscilloscope the encoder is outputting the index pulse.
Halscope will detect the A and B pulses but not the index pulse.
The index pulse is not detected in either LinuxCNC 2.8.0 nor 2.9.4 (rigid tapping just hangs)

Is there something I am missing in my HAL file or is there a timming error in which the encoder pulse is not being read by the 7i92tm? 

Thanks a ton to all of you: jjdege, Billiiles !!!

Off course your hints were pointing into the right direction. I just had to go further than I thought I had to.
In short:
- added debounce
- increased debounce.0.delay

That was it!

I have manual tool change, prompting me for the tool required, hit OK, after change and then it measures tool length automatically. So happy!

Along the welcomed outcome, I stumbled across several problems. I'll wrap up my notes and write a comprehensive howto in due time.

a so happy chris

hi i get a issue...

i have an very old servo driver that needs a 5+ pdm signal about 10khz.
my card i use is a 7i92.. the pdm output is sinking on the 7i92.. correct?
what is the best way to convert it?

thanks

Digging into a bit deeper, whenever I run it in reverse the setting jumps to 8.25 and stays there. If I run it forward it stays around 2.69 with some variation in the next 5 digits. It moves up and down with speed adjustment. 

This should work.

Thank you for letting me know about halshow. There is a wealth of data in here that will be VERY helpful. Unfortunately, the image size exceeds allowable data limit so I can't attach them just yet. Looking into reducing the file size. 

Thanx and I sorry about changing subject line...didn't realize it created problems.

I’ll test this out.
I ran the latency test before but wa slightly confused how to read them .

I think part of the issue I’m having is the crappy bios and not being able to disable things .

OK so fairly complex...

As I said before, maybe the first step is to take a look at
hm2_5i24.0.7i83.0.2.analogout0 in halshow when running
the spindle in each direction.

Dear new Member please don't change the Subject when posting it renames the thread in the Index and makes it hard to find

4GB RPI5 is fine, if you are going to jump that way. But I'd be more inclined to look at the x86 offerings from Odroid. I've been using one for 4 or 5 years without an issue.
