@SANJR please post your config.g, the homing files, daemon.g and the macros you refer to.

Hi Tony pasted the filesplz take a look .......

@SANJR I believe you have to rethink the daemon.g code or the macros. They should only be active after x,y,z-axes are homed.
You can check for homed axes in the object model.

I'm not sure where the variables for homed axis can be found, maybe someone else can chime in?

Hi

Yes you are correct. The daemon and the macros needs to be active after homing the first motion X,Y,Z axis. I have pasted all the files plz take a look......

And about checking for the homed axes in the object model? Sorry not able to understand where and how to check the object model.... Apologies i am not able to understand.......

    while (global.weldtorchstate == 1) ; maybe an if-condition would be better here?
    G1 H4 U99999 F1000 ;selects the U axis & sets the feedrate

G4 S0.2 ; this delay should be related to the while(true) loop

@o_lampe

Thanks

Modified the daemon file

Problem still exists.

You have no indentation in your second while statement.

Hi Owen,

Is it the while (global.weldtorchstate == 1) refereing to?
And indentation meaning.....could u plz show it in the code plz

@oliof

Thanks oliof

Will check with the indentation modified

Thanks Owen

By changing the indentation was able to get it right

Its good now
