How to Install LinuxCNC?

I wonder if it is this:

Do you have that connected up in a postgui HAL file or something?
(If nothing else is connected to that signal anywhere then it isn't that)

No. I just use the PNCConf in 2.9 from your repository (on the first page).

I am running out of ideas.

If M3 S500 does not make the pin spindle.0.speed-cmd-rpm = 500 then something very strange has happened.

You could try
M3 S500 $0
Just to make sure that you are turning on the correct spindle.

M3 runs correctly - forward. (I see reactions in halshow)
M4 no reactions - backward. (I see NO reactions in halshow)

But to try this I can only on Monday.
Do you have any Mesa Card (maybe 7i96s) and LCNC 2.9 to make a simple config in PNCConf with step/dir spindle to test it? (just a PC and a mesa card - no real drivers and spindle, just to see the LCNC reactions for spindle commands)
Because it will take a lot of time to find out what is the problem with the backward rotation in LCNC 2.9 with step/dir spindle config.

As you can see here the forward command works correctly with spindle.0..
But the backwards NOT.

I'm from Ukraine, so at home we have no electricity... Just a few hours a day.

The Mesa board can’t have anything to do with this, if the speed isn’t getting to HAL then it isn’t even reaching the Mesa card. 


If you are using LinuxCNC v2.9 or 2.10 then maybe try adding MAX_REVERSE_VELOCITY to the INI file?
linuxcnc.org/docs/devel/html/config/ini-...:ini:sec:spindle-num


If not, can you try a couple of experiments? 

if you do M5 and then M4 is it the same?

What does M3 S-500 do?

I do not understand why the PNCConf doing not correctly working machine configs... Or why the LCNC have no reactions...
Or it's because there are some new features and not added yet to PNCConf?

This helped.
Added this line
MAX_REVERSE_VELOCITY = 2000.0

This - not.

So, it now goes in reverse at 1rpm.

Does it only do 1 rpm in both directions?
