wrong scale thc of the z axis during cutting on qtplasmac

There is nothing in those to be concerned about, they are just informational warnings.

As a workaround, setp the thc-feed-rate pin to 1500 in the Hal file and see if it works OK for you. In the meantime I will see if I can determine why it is happening.

Also I agree with Greg that you should use Auto Volts.

Edit: Also set PID P to 10 and PID I to 0
 

Auto Volt "should" work best but you have to make sure that your Pierce Hieght is correct after doing some probe tests and also the the Cut Height is correct in the Parameters. With Auto Volts you don't need to worry about the Cut Volts in the Parmeters.
Did the THC work ok after setting it to 1500?
What Locale do you use?
 

Always here, except when sleeping, and i do not do much of that!
Was bussy cutting some keyhangers, need to wire a cnc controlled camera sliders, need to make some extension cables for 3D printers to make them direct drive and get rid of the bowden tube as i am pushing them way beyound what they can handle, monut 2 more Creality CR-10 Max and test them, print some stuff, etc etc.
But still here...

That’s great news!  I am happy you got it all sorted out.  Now you can get to the fun part:  making sparks!  

Enjoy!  

Thank you Billy, i am sure Phill and Snowwy fixed that, i just did not have the time to do a new config as the main machine has more than just ins and outs, has also drive faults....
BTW, all that i said above i had to do, scratch that, i have to go fix the Elumatec, all the drives went dead and they do have power going to them.
