Spindle CW and Stop Toggle Button was created by N3pu

Hey

I want to add a hardware momentary pushbutton to Start the Spindle CW if it´s not turning.
If it´s turning (no matter if CW or CCW) and the Button is pushed again the Spindle should stop.

Could someone help me?

I just got the Button configured that it will run the spindle CW by pushing:
net spindle-manual-cw <= hm2_7i76e.0.7i76.0.0.input-11

But how should I handle the "if (hm2_7i76e.0.7i76.0.0.input-11 && (spindle-manual-cw OR spindle-manual-ccw)) then {spindle-manual-stop}" ?

Jannik

On the phone so not much help, but search for latch or flip-flop, both are included components of LinuxCNC and both can be used for it... or toggle, aslo included.

My spindle control uses multiclick component to turn on CW or CCW. One press CW, double-press CCW. Second button for OFF.

With one button (only) you could have double-press STOP instead of CCW. Or one press STOP, double CW, triple CCW.

Here's what I use:

net BTN-SPIN0-ON        => multiclick.s0.in
net SPIN-MAIN-FWD       <= multiclick.s0.single-click-only
net SPIN-MAIN-FWD       => halui.spindle.0.forward
net SPIN-MAIN-REV       <= multiclick.s0.double-click-only
net SPIN-MAIN-REV       => halui.spindle.0.reverse
net BTN-SPIN0-OFF       => halui.spindle.0.stop

signal BTN-SPIN0-ON connected to momentary pushbutton HAL-in pin.

Thank you.

I don´t know how to handle my "idea" with a flipflop or a toggle. I also read that some users did more or less similiar things with that kind of component, but not this exactly one. Multiclick sounds very interesting and easy, too. I didn´t knew before.

I wrote my kind of idea with an and + not component. I will give it a try today on the machine. For now it´s just written "offline":

# --- SPINDLE-MANUAL-CW AND OFF ---
#net spindle-manual-cw <= hm2_7i76e.0.7i76.0.0.input-11

#Create Spindle-Enable-NOT Signal
loadrt not count=1
addf not.0 sero-thread

net spindle-enable => not.0.in
net spindle-enable-not <= not.0.out

loadrt and2 count=2

#spindle-enable AND button_spindle THEN spindle Stop
addf and2.0 servo-thread

net spindle-enable => and2.0.in0
net button_spindle hm2_7i76e.0.7i76.0.0.input-11 => and2.0.in1
net spindle-manual-stop <= and2.0.out

#!spindle-enable AND button_spindle THEN spindle CW
addf and2.1 servo-thread

net spindle-enable-not => and2.1.in0
net button_spindle => and2.1.in1
net spindle-manual-cw <= and2.1.out

This seems to work:

loadrt and2 names=spindle_button.cw,spindle_button.stop

# --- SPINDLE-MANUAL-CW AND OFF ---
#net spindle-manual-cw     <=  hm2_7i76e.0.7i76.0.0.input-11

loadrt edge
addf edge.0 servo-thread
setp edge.0.in-edge FALSE
setp edge.0.out-width-ns 18000000

net button_spindle_full <= hm2_7i76e.0.7i76.0.0.input-11
net button_spindle_full => edge.0.in
net button_spindle <= edge.0.out

#Create Spindle-Enable-NOT Signal
loadrt not count=1
addf not.0 servo-thread

net spindle-enable => not.0.in
net spindle-enable-not <= not.0.out

#spindle-enable AND button_spindle THEN spindle Stop
addf spindle_button.stop servo-thread

net spindle-enable => spindle_button.stop.in0
net button_spindle => spindle_button.stop.in1
net spindle-manual-stop <= spindle_button.stop.out

#!spindle-enable AND button_spindle THEN spindle CW
addf spindle_button.cw servo-thread

net spindle-enable-not => spindle_button.cw.in0
net button_spindle => spindle_button.cw.in1
net spindle-manual-cw <= spindle_button.cw.out

Thank you Guys. I begin to love this Software

Welcome to the dark side!

I was hooked the first time i edited a hal file, it was like entering a new universe of possibilities.

Wait until you realise just how easy it is to write your own custom HAL components.
