I would use pncconf  (the new one in the link) or MesaCT
and avoid AI as it's really just a time sink here.

I have never seen a missing module in 2.9.4

( There is no motion.so in LinuxCNC so don't take bad advice from AI )

Every other option is going to require you to do some wiring.

Even something such as this, github.com/clough42/electronic-leadscrew, will require you to do some wiring. And this is only a solution to screw cutting and doesn't have any cnc capabilities, tho it doesn't connect to a computer.

Once a again another Electronic Lead Screw, www.rocketronics.de/en/els/ solitaired no connection to a PC,no cnc capabilities but does other some extra features. Is still a user install, so there is wiring involved, but no connection to a PC. not really a budget solution.

First mistake was using a buck conveter, 2nd I would seem to be not checking the operation of the buck converter prior to connecting everything up. 3rd mistake would have been to triple checking everything.

Simple solution would have been to power the breakout board from a known and working 5v supply or whatever voltage the BoB required.
 

Thank you very much for your help.

There is no specific driver for the 7I95T, its supported by LinuxCNCs hm2_eth driver.

Normally you don't need to do anything with the on card firmware unless you have some
specific different I/O requirements. ( Like you want one step/dir output to be PWM/DIR or
you have parallel daughtercard  )

Not sure what explains the initial lack of functioning, possible an issue with the 7I76
config file conversion.

OK there's only one yellow LED on in the center of the board.
so that means analog power issues.

Most likely problems are:

U33 (74ACT04) bad ( can be damaged by a 5V surge to 6.5 or 7V )

Q3,Q4 (FDN337,NTR2101) bad ( can be damaged if U33 fails )

A bad OP-AMP = U3,U8,U14,U20,U28,U35 (MC33179) for channels 5,4,3,2,1,0
Note that if an OP-AMP failed, it's most likely the ones you had
connected.

I would try replacing U33 first and then rechecking.

 

 

I see. This happened after we tried to cut with max 105amp current on the plasma to be able to cut 20mm.
I can replace any parts if you give me the part numbers. This is the second 7i77 !! It took more than 2 months I think to get this one.
And I will need any useful guidance you can think of to avoid this kind of issues in the future, please.
The mesa 5v is now supplied by an external power supply. It was provided by the pc psu up till this issue occured.
So to sum up the current situation:
When i click machine enable linuxcnc detects voltage on aout0 and aout1 and activates the soft estop. This explains why even when I disconnect the analog outputs the machine does not jolt but linuxcnc still thinks the machine is running away. Am I getting it right?
and here is a picture of the mesa leds. One red led on the bottom right side and the others are yellow. 

pulse width was already 100,000 ns so that wasn’t the issue.

i downloaded mesact, chose 7i95t and when i switched to the firmware tab got a message that no firmware was found, prompting me to download it which i did.

then built the config, and it worked perfectly right off the bat so firstly thanks so much for the help here!

i’m curious what this missing firmware was - since no flashing happened im to understand this isn’t the board’s firmware, so i’m assuming then its firmware on my desktop for communication with the 7i95t?

before, i was using hm2_7i95 which was available to the HAL (not 7i95t which the HAL complained about being missing once I ran LinuxCNC with it initially). so this is just hm2 “driver” firmware for 7i95t which was missing on my debian?

No i am not streaming, but i did try screen recording and OBS was mad at me for using such a big screen so it recorded just 1/4 of it!
I do not think it is worth streaming as:
1. i am old so reflexes are not what they were 30 years ago
2. i play using a Logitech MX3 Master wireless mouse, any gamer would cringe at this as it is big and heavy and slow (but i do have big hands so it fits nicely)
3. i have 43 hours of play time in over 4 years
4. takes more than once to finish some levels on Nightmare difficulty
5. helps a lot with sweating !

I might do a shop tour video soon, just need to kick myself in the behind and do it.
P.S.
Just in case you missed the PC build topic, i got those 96GB of DDR5 5200 RAM for 146 Euro, where the normal price is above 400 Euro, new with warranty. Probably a typo instead of 416, but i ain't complaining!

I decided to go with Scylla From BTT since I have good support and documentation from grblHAL but I didn't buy anything yet because I still haven't finished mechanical part of my printNC project yet. So let me know of you have good news Because I really want to go with Linux CNC

Yes, start with all the settings that’s possible to get in MesaCT, 

Spindle relay would probably be good enough for now because the mill has a gearbox and 2 speed motor but that’s possible to fix easily outside of software if necessary, 

For some reason there’s a lot of modules that’s missing and causing faults, I don’t know maybe the new changes to 2.9.4 don’t need them and the AI think they should be there and write HAL with functions that’s not supported any longer 
 

Yep, I think you normally tune the inner (velocity in this case) loop first

Yes, you will probably need to setup the MPGs manually

MesaCT should allow you to setup home/limit switches,
your coolant outputs and the Spindle control outputs
(not sure about the spindle PWM)

So I would setup the limit/home switches and various outputs
next ( since support for these is built into MesaCT )

At one point I got these pins to register counts in Halmeter:

hm2_7i95.0.inmux.00.enc0-count
hm2_7i95.0.inmux.00.enc1-count
hm2_7i95.0.inmux.00.enc2-count
hm2_7i95.0.inmux.00.enc3-count

But ended up getting errors for missing module: Motion.so so tried clean install and wiped everything,

MesaCT is a useful tool but haven’t found any encoder settings other than motor encoder setting,

I’ve tried to flash different firmwares also because some firmwares doesn’t have all settings available for encoder and spindle in MesaCT,

At the moment I’m running 7i95t_1pwmd

I think 7i95t is only supported by MesaCT, tried to use pncconfig because I’ve seen posts about people using the 7i95 config and edit I/O mapping and such, but couldn’t find the 7i95 either.

This is the basic function, it’s possible to jog the machine with buttons in QTdragon 

for # 1 and #7 I would use the built-in MPG encoders.

I don't know what if any MPG setup options MesaCT has
(it should be able to setup limit/home switches and spindle controls)

No sure if any configuration utility knows the 7I95/7I95T
MPG count pins but they would be:

hm2_7i95.0.inmux.00.enc0-count
hm2_7i95.0.inmux.00.enc1-count
hm2_7i95.0.inmux.00.enc2-count
hm2_7i95.0.inmux.00.enc3-count




 

That is an amazing list! Just wondering, have you updated it recently ?

I had a version of Sheetcam that could run on Linux without limitations (free version) but I have lost it and could not find it for download anywhere. Any clues on this ?

Thanks
