Sorry for the delay, life got in the way.

Long story short test with a DVM were positive, could not test spindle due to the late hour.  At "m3 s25000" I am putting out between 9.98v and 9.99v, I hope the fluttering does not effect the Spindle performance.
 
I ended up with:
OUTPUT_SCALE = 12.27V/10V * 25000 = 30675

The issue is the power supply, currently I have one PSU that supplies both +-5v, +12v, the other PSU I have is 48v for Steppers.  the issue is you can only adjust the 5v side, the 12v is only "approximately 12v".

From the manufacture's documents:

Accurate voltage regulation is not guaranteed if the load does not draw the minimum current.

Looking at the block diagram the reason becomes clear: only Channel 1 (5V) is regulated via a feedback loop. Channel 2 (12V) is open loop and unregulated.So you have to adjust the 5V output with the potentiometer while your intended load is drawing its usual current... and you will get "approximately 12V" on the other output.Also the 12V output will fluctuate depending on current draw on the 5V output.

Of course you don't find these things out until you go digging.

The 12v side does fluctuate between 12.26v and 12.27v, I used the latter in your formula.

There may be a separate 12v PSU in my future, if I can make space in the controller box, which is currently packed.  Should have started with a bigger chassis, but I choose to use an old PC case.

Thanks for all the help, on to the next issue and I will have to test Spindle in daylight hours.


 

Thank you, I will try that now!

I have an older PC PSU with resistor (well 12V/55W cal bulb connected to 5V) powering a nearby gas station LED sign, all 420W of it, for over 14 years.
New ones do not need that, they control the 12V strictly.

For a moment there i thought is said SteamDeck !
Enter the HMI users in droves now...

 

Some folks may not have seen the StreamDeck before.  It's commonly used by live streamers to control their live streaming setups, or in video and audio production work.  It's essentially a macro pad that gives you a number of physical buttons, with the capability of putting graphics on a display area behind each button.  It's like a touchscreen in a way, but it gives the experience of tactile buttons.

They are not really built for a harsh industrial environment like many machine shops, but I think in cases where regular keyboards and touchscreens are surviving, these would be fine too.  The older models can often be picked up used for small money.  Mine is an older "Streamdeck XL" with 32 buttons, and there are also smaller ones available.  There are also newer models with knobs, though my project does not support these yet.
 

I've been working on a new project that adds native StreamDeck support to LinuxCNC.  This allows creating control buttons that both control HAL logic, as well as respond to it and show status.

I made a quick video to show the basic functionality.



The project is of course open source (GPL3) and available on GitHub .  I would say it's early days, but it's there if anyone has a StreamDeck and wants to play around with it.

cheers,

yeah thats the conclusion i came up with too. thanks for responding. i guess is no free lunch. i am going to have to bite the bullet and buy a drive. you guys are amazing on this site. thank you all for all the advice and guidance you provide.

No, that is not correct. If you have a 0-10V input you
should not apply negative voltages.

What I would do is this:

7I96S SPIN+ --> +12V
7I96S SPIN- -->  GND
7I96S SPINOUT --> SPEED CONTROL

Then set the spindle OUTPUT_SCALE to 12V/10V * 25000 = 30000
and spindle MAX_OUTPUT to 25000

(and offset mode false)

You have to be careful here. I have a 12v/5v Meanwell power supply (in a frame) that is useless for this because the 5v side needs a load on it for the 12v side to work. The required load far exceeds the power draw of a Mesa card. It was suggested I add a ceramic resistor but the generated heat and power consumption made me scrap the idea.
 

Good catch Rod.  It's been a few years, and I completely forgot I had to add a resistor to get the 12 & 24v outputs to work.

Having said that, the PSU (with resistor) has been in (mostly) daily service with no issues.

Should fix the issue.

The 5I25t manual is just a clone of the 5I25 manual
but not all bitfiles have been built yet
 

In a terminal
latency-histogram --nobase --sbinsize 1000 --show
leave it on, click on glxgears 5 to 10 times, watch some youtube, and take a screenshot after half an hour.

9 says is encoder error, no 69 there.

Slow the servo thread to 2ms, until you get the latency sorted out. I don't think you'll get away with a 1ms servo thread.

Try updating the PC/motherboard BIOS. Sometimes they ship with crap that generally works then sort it out halfway through the product lifecycle.

i bought this drive and motor from a vendor on ebay, en.bergerda.com/filedown.php?id=49, and it came with an error when i turn it on it flashes 9 and then 69 and i am unable to clear it. i am wondering if anyone has any ideas.on how to clear this error, or if it is even clearable. i'm sure there's a reason they didn't want it back. they sent me another drive but i would like to get this one working if i could. another drive is like $300. the motor works, i checked it with the other drive. i have gone through all the diagnostic procedures in the manual. and there is no error code in the manual for error 69 any help would be greatly appreciated. i did contact the manufacturer but they were little (if any) help.
