Timed delay

Hi good folks  

I'm fairly new to linuxcnc, so please go easy on me lol.

I will try to explain what I need. It's not straight forward but im sure one of you geniuses will be able to help me out.

I have a haas mini mill, running linux cnc (probebasic), im 99% finished just the atc pneumatics to do. Now the haas mills have two solenoids to operate the drawbar.

 one opens and closes for 0.5 seconds first to pre charge the cylinder with 20psi. Like a soft push.

the second dose all the hard work and takes over immediately after the first and stays open untill the button is released.

how would this be accomplished?  I have found timedelay, but not sure how to implement it. 

I would also like to be able to control this action with a physical input button. 

I'm on latest linuxcnc using a mesa 7i95T.

Many thanks in advance.

I would do this with two components: a oneshot component and an and2 gate:

The oneshot would be set for 0.5 seconds and triggered by the drawbar signal.
The active high output of the oneshot would drive the low pressure solenoid
(so its driven for 0.5 seconds on the rising edge of the drawbar signal)

The high pressure solenoid would be driven by the output of the and2 gate
The and2 gate inputs would be the drawbar signal and the active-low output of the
oneshot. The active low oneshot output would disable the and2 output driving
the high pressure solenoid for the first 0.5 seconds when the low pressure solenoid
is activated.

 

I did try one-shot but couldn't get it to work. So I then tried timedelay and nearly have it working

# Input and output configuration
net button-press <= hm2_7i95.0.inmux.00.input-05 # Connect input pin 5 to signal button-press
net relay-1-control => hm2_7i95.0.ssr.00.out-01 # Connect signal relay-1-control to relay output 1
net relay-2-control => hm2_7i95.0.ssr.00.out-03 # Connect signal relay-2-control to relay output 3

# Load and configure timedelay
loadrt timedelay count=1
addf timedelay.0 servo-thread

setp timedelay.0.on-delay 1.0 # 1-second delay
setp timedelay.0.off-delay 0.0 # No off delay

# Timedelay connections
net button-press => timedelay.0.in # Link button-press signal to timedelay input
net relay-1-control <= timedelay.0.out # Link timedelay output to relay-1-control

# Direct button connection to second relay
net relay-2-control <= button-press # Relay 2 activates directly with button press

Problem I'm having is I'm getting the error pin button-press does not exist. Any ideas?

The error is because button-press is a signal, not a pin
Looks like you need to delete one signal as you have two
with the same function:


# Input and output configuration
net relay-2-control <= hm2_7i95.0.inmux.00.input-05 # Connect input pin 5 to signal button-press
net relay-1-control => hm2_7i95.0.ssr.00.out-01 # Connect signal relay-1-control to relay output 1
net relay-2-control => hm2_7i95.0.ssr.00.out-03 # Connect signal relay-2-control to relay output 3

# Load and configure timedelay
loadrt timedelay count=1
addf timedelay.0 servo-thread

setp timedelay.0.on-delay 1.0 # 1-second delay
setp timedelay.0.off-delay 0.0 # No off delay

# Timedelay connections
net relay-2-control => timedelay.0.in # Link button-press signal to timedelay input
net relay-1-control <= timedelay.0.out # Link timedelay output to relay-1-control

# Direct button connection to second relay
# Cant drive a signal from another signal:  net relay-2-control <= button-press # Relay 2 activates directly with button press

Many thanks for your reply. So how would I make one button activate the two outputs with the delay of one second? I want when the input 05 is pressed relay one opens for 1 second. Once the relay closes after the one second, then relay 2 opens and stays open untill I release the button
I'm so lost with this

This may be closer to what you want:

# Input and output configuration
net button-press <= hm2_7i95.0.inmux.00.input-05 # Connect input pin 5 to signal button-press
net relay-1-control => hm2_7i95.0.ssr.00.out-01 # Connect signal relay-1-control to relay output 1
net relay-2-control => hm2_7i95.0.ssr.00.out-03 # Connect signal relay-2-control to relay output 3

# Load and configure timedelay
loadrt timedelay count=1
addf timedelay.0 servo-thread

loadrt xor2
addf xor2.0  servo-thread

setp timedelay.0.on-delay 1.0 # 1-second delay
setp timedelay.0.off-delay 0.0 # No off delay

# Timedelay connections
net button-press => timedelay.0.in xor2.0.in0       # Link button-press to timedelay and logic
net relay-1-control <= timedelay.0.out  xor2.0.in1 # Link timedelay output to relay-1-control and logic
net relay-2-control <= xor2.0.out                           # Link xor out to relay-2-control
 

Thanks for the code, im getting this error on startup ./main.hal:239: Pin 'xor.0.in0' does not exist

Works perfectly! Thank you so much! Do you have a link to send a tip?

A good tip would be to help the next guy with a hal / LinuxCNC question.
