QTPlasmac and mesa7I96 questions

Hello,

Im trying to take a peek at qtplasmac and mesa. I dont have an actual machine but I was thinking about spinning some motors and just playing around with it. I have 2 questions:
- I am not able to home the Y-axis and I dont seem to be able to disable homing.  I assumed that NO_FORCE_HOMING = 1 would allow me to hog without homing but seems thats not the case? I have almost everything disbaled but cant get the machine to "Power ON"
- Laser button, I wanted a user button to toggle an output and thought to use the laser, im doing something incorrectly as I get an error about the button code
BUTTON_7_NAME = LASER
BUTTON_7_CODE = toggle-halpin qtplasmac.laser_on runcritical

 
 

when you config the machine you can choose the force home before being able to do anything. disable this when you set it up.

Laser button to toggle laser on and off. I haven't got this worked out yet but others have. I'm sure they will add to this soon.

Hello,

Thanks the box for "require homing" is already unchecked. I am able to Click home on y and z but not Y (can it be ralted to having a sync axis on y?)

If you check homing configuration in the docs, ther is a heading for immediate homing. I would set up for that. Not sure you can use 2 motors on the gantry that way without home switches so just male it a XYZ machine with 3 motorx.

Hello,

Which doc you refer? I wasnt able find anything from the QTPlasmac doc.

Its nothing to do with QTplasmac. It part of the linuxcnc core.

From the main docs, click open Configuration and there is a link to this. Probably the most important page in the docs!
linuxcnc.org/docs/devel/html/config/ini-homing.html
 

Aah thanks, also the homing issue was about the tandem axis...

Any tips on the user button to toggle an output (I dont need to use the laser, just an output from the mesa).

I am pretty sure you can manually home and jog with a gantry. I have done it before. 

Adding a button in QTplasmac is pretty well documented. 

Add a User Button

Then you can manually edit hal files to do whatever you want.

Ok so I´m a bit lost, something just doesn click in my head...

From the plasmac manual:
The following HAL bit output pins are always created and can be used by either the Toggle HAL Pin or Pulse HAL Pin custom user buttons to change the state of an output.
qtplasmac.ext_out_0
qtplasmac.ext_out_1
qtplasmac.ext_out_2

I cant find these from HAL show or from my "mesa_test.hal". But I tried this anyway:
Mesa_test.ini:
Mesa_test.halBut no dice, I have tried to look from the manuals and the mighty google but there is something that I dont understand or maybe I am doing it wrong.

As far as I understand in the button code I refer to a pin to be toggled and then in the hal file I map the pin to an output. Could someone please point me to the correct direction or give me some bed time reading?

Dont mind the # in the files.
