Spindle delay was created by f3nix

Hi guys.
I'm just starting so please be gentle

I would like to add a delay for spindle to come up to speed. I'm using version 2.9.3

I have tried adding these lines:

Code:

loadrt timedelay count=1
addf timedelay.0 servo-thread
setp timedelay.0.on-delay 5
net spindle-on => timedelay.0.in
net spindle-timer <= timedelay.0.out
net spindle-timer => spindle.0.at-speed

But I get error with this text:

Code:

254: Pin 'spindle.0.at-speed' was already linked to signal 'spindle-at-speed'

The whole spindle section looks like this:

Code:

#*******************
#  SPINDLE S
#*******************

setp   pid.s.Pgain     [SPINDLE_9]P
setp   pid.s.Igain     [SPINDLE_9]I
setp   pid.s.Dgain     [SPINDLE_9]D
setp   pid.s.bias      [SPINDLE_9]BIAS
setp   pid.s.FF0       [SPINDLE_9]FF0
setp   pid.s.FF1       [SPINDLE_9]FF1
setp   pid.s.FF2       [SPINDLE_9]FF2
setp   pid.s.deadband  [SPINDLE_9]DEADBAND
setp   pid.s.maxoutput [SPINDLE_9]MAX_OUTPUT
setp   pid.s.error-previous-target true

net spindle-index-enable  <=> pid.s.index-enable
net spindle-enable        =>  pid.s.enable
net spindle-vel-cmd-rpm-abs     => pid.s.command
net spindle-vel-fb-rpm-abs      => pid.s.feedback
net spindle-output        <=  pid.s.output

# ---PWM Generator signals/setup---

# ---setup spindle control signals---

net spindle-vel-cmd-rps-abs    <=  spindle.0.speed-out-rps-abs
net spindle-vel-cmd-rpm        <=  spindle.0.speed-out
net spindle-vel-cmd-rpm-abs    <=  spindle.0.speed-out-abs
net spindle-enable             <=  spindle.0.on
net spindle-cw                 <=  spindle.0.forward
net spindle-ccw                <=  spindle.0.reverse
net spindle-brake              <=  spindle.0.brake
net spindle-revs               =>  spindle.0.revs
net spindle-at-speed           <=  spindle.0.at-speed
net spindle-vel-fb-rps         =>  spindle.0.speed-in
net spindle-index-enable      <=>  spindle.0.index-enable

# ---Setup spindle at speed signals---

#sets spindle-at-speed true

loadrt timedelay count=1
addf timedelay.0 servo-thread
setp timedelay.0.on-delay 5
net spindle-on => timedelay.0.in
net spindle-timer <= timedelay.0.out
net spindle-timer => spindle.0.at-speed

Could anyone push me in the right direction?
Thanks.

Cheers,
Mateusz

remove/comment this line in your spindle section:

Code:

net spindle-at-speed           <=  spindle.0.at-speed

Thanks @Aciera
I've tried that but the machine does not move after that. Trying to run some gcode the spindle starts but nothing else happens.

Cheers,
Mateusz

P.S. Are the code blocks broken in the forum?

Your signal names don't match up.
replace

Code:

net spindle-on => timedelay.0.in

with

Code:

net spindle-enable => timedelay.0.in

the editor is buggy and messes up the formating when you edit things. Use the 'Source' button in the top left of the editor to see the tags and move them around.

Thank you @Aciera.

It does work as expected now.

Have a nice one.

I just wanted to register that this solved the same issue for me on 2.9.7. There are older solutions on the forum, for example " Automatic pause when spindle is started " from 2015, but they don't reflect current pin/signal names. Modified default spindle control HAL section below, two lines commented out and six more required.

Code:

# ---setup spindle control signals---

net spindle-vel-cmd-rps        <=  spindle.0.speed-out-rps
net spindle-vel-cmd-rps-abs    <=  spindle.0.speed-out-rps-abs
net spindle-vel-cmd-rpm        <=  spindle.0.speed-out
net spindle-vel-cmd-rpm-abs    <=  spindle.0.speed-out-abs
net spindle-enable             <=  spindle.0.on
net spindle-cw                 <=  spindle.0.forward
net spindle-ccw                <=  spindle.0.reverse
net spindle-brake              <=  spindle.0.brake
net spindle-revs               =>  spindle.0.revs
##net spindle-at-speed           =>  spindle.0.at-speed
net spindle-vel-fb-rps         =>  spindle.0.speed-in
net spindle-index-enable      <=>  spindle.0.index-enable

# ---Setup spindle at speed signals---

##sets spindle-at-speed true

# 5-second spindle ramp delay
loadrt timedelay count=1
addf timedelay.0 servo-thread
setp timedelay.0.on-delay 5
net spindle-enable => timedelay.0.in
net spindle-timer <= timedelay.0.out
net spindle-timer => spindle.0.at-speed

My spindle VFD is connected as follows for simple "run" operation with no feedback:

Code:

net spindle-enable  =>     hm2_5i25.0.7i77.0.0.output-00
