M101 again

Hey guys, I'm back with a little bad news. I got the file set up and it doesn't stop the program with an error anymore but it still dose not trip the relay. I have tried every thing I can think of with no luck. I changed the config to coolant on / coolant off to that pin and it work fine.I must be missing something here.
Thanks in advance

Hello,

You might try .. open hal, select watch and then select the pins you are using to see what is changing when you run your command. In hal you can also enter commands to test them, try yours and see if it works there. Also now that you have a new command in your file maybe paste the current file.

I'm not sure how to write a command I tried everything I can think of. When I click on wach the screen goes blank. Is there maybe an easier way to open and close two more switches? I'm not doing so good with this one.
Thanks Tim

I'm trying to open and close two air cylinders with pin 14 and Pin 1
Thanks Tim

Tim,

What you are trying to do makes sense.
If I understand correctly your plan is to apply a signal to a parallel port pin with hal.
From the parallel port the signal goes to your breakoutboard which contains the relay for the cylinder. What breakout board are you using?

After you start EMC select Machine /show Hal configuration in EMC then select watch, select the pins you want to watch and enter your command at the bottom to see if it works. You can also try your command from the MDI line of EMC or by running a file.
If working the status of the pin should change. If the pin changes and your relay still does not work check your pin numbers.

Good luck and let us know how it is working out.

After selecting the line with parport 14
I typed [m101] setp parport.0.pin-14-out 1 [/m102]
clicked execute and got Error invalid code

When I type in the command word for word as advised, it still comes back error message "invalid command name code. That is why I tried using M101 and M102 in place of code. If I assign spindle brake on off to pin 14, all the hardware works correctly.
I am sure my file is in the correct directory becasue it runs through on the program when I run it. In the configuration file I set pin 14 out 01. I have tried all of the others with no luck.

M101
#!/bin/bash
# file to turn on paraport pin 14 to open the collet closer
halcmd setp parport.0.pin-14-out True
exit 0

M102
#!/bin/bash
# file to turn off paraport pin 14 to open the collet closer
halcmd setp parport.0.pin-14-out False
exit 0
It is set to be an executable and in home /tim/emc/nc

My command in the program test code(which I wrote) is simply M101 and M102.

G20 f95
G1 X9.0000 Y2.0000 A11.0000
M 101
G1 X0.0000 Y0.0000 A0.000
M 102

I use a hobbycnc pro 4 axis driver board


Forgive me for my lack of knowledge, I am still learning. This one thing has been the toughest so far, and the one thing that stops me from production. I have built this machine to manufacture a product I have invented, the entire thing has been a college course or two for me in the past 7 months.

Any help is appreciated.
