I will go read some more about G52, thanks!

No its Mach 3. The seller of the Mashin did not include the hard drive so i had to install windows and Win11 was just wat i downloaded.

Ewww...
Windows 11!

Is that Mach 4?

I wanted to be sure ... HAL_BIT will always return 'TRUE' or 'FALSE':

getp evokes the function do_getp_cmd, and inside it calls data_value2 to format the response:

github.com/LinuxCNC/linuxcnc/blob/73337a...cmd_commands.cc#L883

here is where HAL_BIT goes to 'TRUE' or 'FALSE':

github.com/LinuxCNC/linuxcnc/blob/73337a...md_commands.cc#L2473

So checking for '0' is probably unnecessary, but it doesn't hurt either.  

Really don't see what could be different between configurations that affect basic communications.

unless there is some marginal power issue (does the 7I96S reset when starting the 5 axis configuration?)
Or maybe a memory fault of some kind in the PC, the reported error really has nothing to do with the number
of axis.

And as I said, your 5 axis hal/ini files work fine here with a 7I96S

A pncconf created configuration might be worth a try, just to see if a quite different
5 axis configuration changes the symptoms.

 

Thank you for the help, I had narrowed it down to the rewrite_material_file method before I left for Thanksgiving dinner.  You definitely saved me time getting the rest of the way there.  From what I can tell without doing a bunch of digging, getp will return 'TRUE' or 'FALSE' when the halpin is setup as a 'bit'.  

I pushed your fix for this to the master branch:  github.com/LinuxCNC/linuxcnc/commit/7333...d08fd2855851c8ee91b3

I also found a copy/paste bug and fixed that as well.

Thank you again!

I’ll post my wiring diagrams once I’ve got them more organized, I’m working out of a google sheet that’s set up for tracking the status and purpose of each wire.

Okay, I think I understand why it is doing what it does. 

The brake is working, but only during a speed change. So with C13 = 0.5S, and C023 at 110% current, the spindle speed change from 70 Hz to 20 Hz is braked (nicely). So that solves my decel between CSS facing cuts.

But switching spindle off, makes the spindle coast down. Since I am commanding the VFD with analog 0-10V, I thought spindle off just meant 0V commanded, but now I think about it, I sort off remember being surprised that is not the way LinuxCNC works. I suspect the spindle stop actually  deactivates the spindle drive enable signal which I have connected to VFD Pin 28,  and therefore the VFD is disabled every stop.

Since I controlling the VFD with a 0-10V analog signal, what can I do to have  LinuxCNC set that analog signal to 0V when I command a spindle stop?

I thought I was only only using Pin 28 it for machine start up and shut down, and E-Stop. It looks like I need to put a delay onto that disable to give the VFD time to be braked down to stop with the analog speed command, before the VFD is disabled.

Those are the thermal overheat switch, which with that wiring will cut power to the main VFD in the case that the brake module overheats. To test it, that connection is not necessary.
 

Makes sense now that I look at the diagram more closely.

Are the LED's on the brake module illuminated?  Green for ready, yellow for braking active?  Just trying to work out if your #2 (dead component) theory is true.

OFF topic/rant

3/ I only have 16A feed at 400V.

Just to make Americans green with envy (i was granted American citizenship but i never went there ):
I have that in every room in the house, that is 3 phase, each capable of 400V at 16A!
And in the shops there are everywhere 3X400V/32A sockets, so yes we can charge electric cars very fast at home, but we do not have many of those cars. I would like one that can do about 50-100KM on a single charge as that is sufficient for my daily use, but i would need another car for longer distances, so i am sticking to my diesel for now...until i build one with some drone batteries and some servo motors i have around the shop!

copy the .comp file to your home folder, open terminal:That will compile and install the file/component where it belongs, then in the hal file there should be the entries pertaining to hyst and it's generated pins as above posted entries from Cofhal

thank you very much, I will try this tomorrow related to hal file, this is an example for a spindle, I believe it is similar for feed? I also need information on where this file should be located, in which Linux folder ``hist.comp``? and do I need to add any line to the ini, except halfile=...

Yes, I always get the same error. I've been trying things all day, changing the connections between the drivers that I'm sure work fine. Everything seems to be working correctly in terms of the electronics. I've tried all possible combinations with the drivers and the connections on the 7I96S.

Could there be a ‘conflict’ because there is another configuration that has worked with the same IP? Could there be some kind of ‘cache’?

If I remove the two added axes from the HAL, then I don't have any problems.
