unfortunately no,
I've tryed the .INI and .HAL codes but not everithing works so I've started this new post ( tool change has worked immediately,visualization of the spindle speed after some mods, a mult2 added )

OK, so what doesn't work, and how does it not work?

the only routine that seems to do something is the drilling

in your files there is also "pyvcp_widgets.py" but Ive fuond no use of this
It mus be linked in some way?

That's curious. One possibility is that you still specify the default number of analogue and digital inputs, what does your "loadrt motmod" line in the hal file say?
(This probably looks like)
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[TRAJ]AXES num_aio=8 num_dio=10
Note the increased number of analogue and digital pins.

You should be able to check in Halmeter if the mdi_command pins are being set high when you press a button.
You should also be able to manually launch the subroutines from the MDI tab, to check that they get found and work.

in your files there is also "pyvcp_widgets.py" but Ive fuond no use of this

This allows you to use "enter" to register a value in the spinboxes. Otherwise the values are not seen by the system until you press the up-down arrows.
You need to put that new version of pyvcp_widgets.py in the place of the old one on your HDD.

thr loadrt motmod is right
I've checked in Halmeter all the signals ,pins ecc and all seems to be ok
I've entered all the values and also moved whit the arrows,I've selected the tool and if I use turning or facing the axis makes only one movement,the go to the starting position and then nothing more.
Shurely somewhere I've make a mistake but I don't understand where

The macros use feed-per-rev mode. Do you have a spindle encoder?
motion.spindle-speed-in needs to be connected and working for feed-per-rev mode

Yes they are connected,
Probably (I'm working on the turning mode ) reading the HAL meter data the turning.ngc waits the spindle speed to be at a set value, I've a gearbox and no inverter so the exact speed needed is never reaced and the program dosn't start.
I'm studing your gcode but I don't have found a reference for well understand how it works(the most problem is about variables)
I would like to make it more simple and step by step add the value passed in the interface to find out my error

If you Halscope them, do they appear to be working?
Negative spindle speed might cause confusion, for example.

I didn't put any wait for spindle-at-speed in my G-code, but it might be in your HAL file.

It's a G4. Just a pause (for one second)
