Possible to manually use laser on a dry run ?

Thanks Snowgoer,

can't remember offhand but that's certainly possible because I was sometimes on another tab.

I used your gcode example and put it in a subroutine that I call from a button on my pendant. Works fantastic, so for my outer profile dry run I can simply turn the laser on, and use the crosshair as though it was the torch itself.
After that I just press my button "Torch to Crosshair" and it moves the torch over to where the crosshair was.


What exactly is the subroutine you're using?

This is the subroutine:

(FILE NAME IS torch-to-crosshair.ngc)

(NOTE - HARD CODE THE XY PERIPHERAL OFFSETS FOR THE LASER CROSSHAIR)

o<torch-to-crosshair> sub
G91 (Change to incremental mode)
G0 X60 Y40 (Move torch by laser offset amounts)
G90 (Change back to absolute mode)
o<torch-to-crosshair> endsub


However, I realised after my last post I need to "reset" the XY values so I'm going to add this line:

G92 X[#5221-60] Y[#5222-20] (This is for G54 only work offsets)

First of all, forget the G92 addition to my subroutine. It was a disaster, so I think I need to study up on co-ordinates and that command LOL.

Back to the new external pin.
Here's a link to the first video showing my pendant activating the qtplasmac.ext_laser_toggle pin but nothing happening on the plasmac:laser-on output pin. 
I made sure the main tab was open.

So as suggested I tried direct from Halshow.
The Set/Clr buttons for 
qtplasmac.ext_laser_toggle pin were greyed out, no doubt because my demux output pin was connected to it, so I commented that line out in my postgui hal file, then the Set/Clr buttons became active.
With the main tab open, this next video shows me using the Halshow Set/Clr buttons to "pulse" the 
qtplasmac.ext_laser_toggle pin yet the plasmac:laser-on output pin still does not activate.

I've attached a copy of my config file too.

Yea, G92 sure is ... something lol

I was a bit confused because the code I suggested will not persist. What I had intended was that you would run the dry run to a spot where you were concerned with the part fitting on the material, and then click the button with that code, which would move the laser pointer to point to the spot the torch was just above.

Similarly, you could just jog around until the cone is over that spot in the preview window, and then click the button to move the laser point over the spot.

I believe having the offset persist throughout the dry run will require work on the software side.

Both of these links say access is denied.

I am not sure how you made the videos (cell phone or screen recorder), but either way I would suggest using youtube to host them. You can easily upload them to your account from your phone, and you can set the visibility to "unlisted" so that anyone you give the link to can see it. Then post that link here. That's how I share them and it doesnt require anyone to download large unprocessed video files (some people here have expressed that they have small Gb limits form their internet service providers).

For screen recording, I use "simple screen recorder", and upload the result to youtube.

Here is from the virtual machine I run:

If it's still not working with the pin unlinked, something else is going on, so I'm going to hold off on looking through the config for now. I probably need to see your videos to better understand.

Here's the YT links Snowgoer.

USING PENDANT BUTTON


USING HALSHOW:


Something is very different to mine and yours. No sign of any activity on mine.
My 2 week "rest" is over and I'm heading out the door to start my new job in a few minutes. I'll have to wait until after work to try using Halshow in sim mode, and see if mine is the same.

you’ll have to change it from private to unlisted (this is from the YouTube app on my phone).  They default to private.:

click the video options, click edit, click set visibility

I decided to simulate your config this evening.  

You are missing a LASER button, because in the [LASER_OFFSET] section of your BEEFYS_PLASMA_DURAMAX.prefs file, but options "X Axis" and "Y Axis" are equal to zero.  QtPlasmaC takes this as "there is no laser".

I recommend following the  Peripheral Offsets Section  of the user guide, which will help you set the offsets precisely.  

Alternatively, if you really dont want to do that, you could manually edit the aforementioned .prefs file to change those options to whatever their values are.

ext_laser_touchoff would not have worked either.

I should note, if you decide to hand edit the .prefs file, you need to do so with LinuxCNC shut down. Otherwise when you exit QtPlasmaC, your changes will be overridden.

Aha, so that's what it is, thanks a bunch Snowgoer.

I would never have picked that one up without your help. My lasers are not even installed yet, still in their plastic bags. I was getting everything working (pendant, hal, 7i96 output, etc) before installing them, so would never be setting their peripheral offsets before they are installed. I'll stick some dummy offsets in place just for testing.

Sorted out the YT video links too. Things are a bit different now from when I last uploaded a video. I had to go through a few question boxes (one of which is asking if the video is made for kids or not) before YT would publish the video. On the last question box was the setting for Private, Public, etc.

UPDATE:
Working good now Snowgoer. Thanks again.
Can now turn the laser on/off from my pendant, woohoo
