Hello all,

I have wired my VFD spindle at speed pin to the input 10 of my 7i96S mesa board.

The pin work correctly when monitored in HAL Show.

In my HAL file I have declared it like so :
net spindle-at-speed spindle.0.at-speed         <= hm2_7i96s.0.inm.00.input-10

But in the QtDragon UI, the At Speed LED turn on immediately at spindle startup.

I am probably missing something ?

Thank for help.

I think you need to
net  spindle-at-speed => some-qtdragon-pin-for-at-speed

check the docs.

I was thinking as you but did not find anything here :

Do you have a spindle speed feedback pin connected?
Qtdragon calculates spindle at speed it's self using spindle request and spindle feedback.
Can you post your config?

No I don't, my VFD is set to feedback a digital signal when at speed.

Here is relevant part of my config :
# SPINDLE IO
# ----------

net spindle-enable spindle.0.on                => hm2_7i96s.0.ssr.00.out-00 => hm2_7i96s.0.pwmgen.00.enable
net spindle-cw spindle.0.forward             => hm2_7i96s.0.ssr.00.out-01 
net spindle-ccw spindle.0.reverse             => hm2_7i96s.0.ssr.00.out-02
net spindle-output-rpm spindle.0.speed-out-abs        => hm2_7i96s.0.pwmgen.00.value
net spindle-at-speed spindle.0.at-speed         <= hm2_7i96s.0.inm.00.input-10

# SETUP MESA BOARD
# ----------------

# General
setp hm2_7i96s.0.pwmgen.pwm_frequency 20000
setp hm2_7i96s.0.pwmgen.pdm_frequency 6000000

# Spindle
setp hm2_7i96s.0.pwmgen.00.output-type 1
setp hm2_7i96s.0.pwmgen.00.scale 24000

net spindle-manual-cw         halui.spindle.0.forward

you can try this.

add the file into your config folder
add this line to the INI under the [DISPLAY] setting:

USER_COMMAND_FILE = CONFIGFOLDER/qtdragonrc.py

This should make the led automatically follow the pin spindle.0.at-speed state

save the file as qtdragonrc.py

I have no error or warning but it does not work.

Here is my full qtdragonrc.py file because you already helped me out in another thread :)

Sorry yes dragon_hd has a different name for the led.
change all references of 'self.w.led_at_speed' to 'self.w.hal_led_atspeed'

Yep, working fine now :)

Thank you.
