We're having issues with TB4 on the mesa 7i76e, there is no relation between the output state and the command from the CNC.
How can we check what the problem is or why it could be that nothing is happening and how can we manually check the state of the outputs.
We already put a 24v signal over the outputs and measured them and they didn't work.
Thanks in advance

Hi,
Great tool but I'm having a problem. I'm running Linuxcnc 2.9.2 on a RPi5 with MESA 7i76E and 7i85S boards. In the Setting/Jog Slider Settings the three Angular Velocity setting are greyed out so I can not enter values. The result of Build Config is a message in the Info tab :Settings Tab:Default Linear Jog Velocity must be greater than zeroMaximum Linear Jog Velocity must be greater than zero

Is there something I've missed in the settings somewhere?
Regards,
Nigelp, li { white-space: pre-wrap; }

Nachtrag:

Inzwischen habe ich das Komando <menu-config> gefunden.
Dieses ist im <.img.xz> enthalten und ist vergleichbar mit <raspi-config>.
Somit kann der Abschnitt mit <raspi-config> entfallen.
<menu-config> zeigt nach Beenden einige nützliche Infos an.

Yeah it did believe it or not. 

I'd probably report that as a bug? 

Too weird... 

Did that solve the out of range spindle speed error?

Ok, all I did was add those params as described above and everything words as described. 
Here's what I did:

OUTPUT_MIN_LIMIT = 5000   <<-- I changed this from zero to 5000
 OUTPUT_MAX_LIMIT = 24000    <<-- no change to this line
 MIN_FORWARD_VELOCITY = 5000
 MAX_FORWARD_VELOCITY = 24000
 INCREMENT = 200

I added the latter 3 lines in green.

Thanks to those who responded with feedback!

No, those are hardware setup parameters and necessary.

Ok, I just added the green FORWARD stuff to my config.. Should I remove the red print?

[SPINDLE_0]
 P = 0.0
 I = 0.0
 D = 0.0
 FF0 = 1.0
 FF1 = 0.0
 FF2 = 0.0
 BIAS = 0.0
 DEADBAND = 0.0
 MAX_OUTPUT = 24000
 OUTPUT_SCALE = 24000
 OUTPUT_MIN_LIMIT = 5000
 OUTPUT_MAX_LIMIT = 24000
 MIN_FORWARD_VELOCITY = 5000
 MAX_FORWARD_VELOCITY = 24000
 INCREMENT = 200
 

Those are hardware settings, I would think pyvcp would use
the ini file spindle settings here:

linuxcnc.org/docs/2.9/html/config/ini-co...:ini:sec:spindle-num

3000 RPM is probably the default value if not specified. This does seem like
a pncconf bug to leave out the generic spindle ini settings

Change it to 24000, save and test.

What I have yet to understand is that the pyvcp-panel.xml file uses a value of 3000. Why is that?

I would expect to see these INI values which I assume are RPM?
OUTPUT_MIN_LIMIT = 0.0
OUTPUT_MAX_LIMIT = 24000

Another stupid question from me. When you say:-
"Connect the 7I83 analog out hal pins to the PID outputs"
Is that a physical wire, or something to be written in the hal file?

In hal, make a new config for 7i76E with 7i77, that should get you all the pins for everything, then make a copy and edit the copy to match the Mesa naming and pins:
Stepgens change from 7i76E to 7i95
Encoders change from 7i77 to 7i95
analog out/pid change from 7i77 to 7i83

Thanks PCW, it's very clear.
the goal is for the milling machine to stop if for some reason the z axis stalls.
otherwise, a rapid crossing with the z in the wrong position can cause a disaster

Not sure what the issue is but looks GUI related
My guess would be the the pyvcp spindle speed
display doesn't have the maximum spindle speed set right
