i have uncomment line 15 and now

Code:

custom_postgui.hal:15: Pin 'pyvcp.frequency-command' does not exist
Shutting down and cleaning up LinuxCNC...

What that means is either that your PyVCP panel does not have a frequency display, or that it is called something other than pyvcp.frequency-command

As a quick test, just delete pyvcp.frequency-command from that HAL line

(That still might not work, I have no idea if the "hy-Freq-Cmd" signal is connected to anything at the other end.)

i have added to pyvcp panel custompanel.xml this

Code:

<tablesticky sticky="w" />
			<label>
				<text>"Frequency command: "</text>
    			</label>
    			<tablesticky sticky="e" />
    			<number>
    				<halpin>"frequency-command"</halpin>
   				<format>"4.0f"</format>
			</number>
		<tablerow/>

and now starts ok but the same problem can not set the rpm

So, what else is the signal "hy-Freq-Cmd" connected to in the HAL?

(Or, to start at the other end, what is motion.spindle-speed-out connected to?)

is not connected anywhere.. How to connect ?
(i don't know anything about hal)

i have comment these lines from stepconf wizard

Code:

#net spindle-cmd-rpm => pwmgen.0.value
#net spindle-on <= motion.spindle-on => pwmgen.0.enable
#net spindle-pwm <= pwmgen.0.pwm
#setp pwmgen.0.pwm-freq 100.0
#setp pwmgen.0.scale 24000.0
#setp pwmgen.0.offset -2.77555756156e-17
#setp pwmgen.0.dither-pwm true
#net spindle-cmd-rpm     <= motion.spindle-speed-out
#net spindle-cmd-rpm-abs <= motion.spindle-speed-out-abs
#net spindle-cmd-rps     <= motion.spindle-speed-out-rps
#net spindle-cmd-rps-abs <= motion.spindle-speed-out-rps-abs
#net spindle-at-speed    => motion.spindle-at-speed
#net spindle-cw <= motion.spindle-forward
#net spindle-ccw <= motion.spindle-reverse

Generally speaking, commenting-out lines of HAL stops things working rather than makes them work.

Can I suggest that you take the time to read the basic HAL documentation?
linuxcnc.org/docs/html/hal/basic_hal.html

Even if you were to revert to relay and voltage control, you would still need to connect those to the spindle speed control in HAL.
