Control the Z axis when a program is running.
« on: November 07, 2008, 09:47:32 PM »
Hi, I am running a plasma/flame torch on my table and I was wondering if it is possible to run the z axis manually at the  same time mach 3 is running a program? Let me know if this would work.

What control are you wanting - height and on/off - or is the "target" undulating.

You can search the forum - this question has come up before - and, I think, been answered.

If you look in Config/Ports and Pins/Mill Options you will see a box refering to THC which I think is Torch Height Control. THis allows you (I think) to alter the height of the Z axis whilst "on the move".

I don't know for sure, becasue I don't use the feature.
Not me driving the engine - I'm better looking.

I have searched the forum and can not find any good answers. I will check THC box and see if it lets me do that.

hi, its easy to do.you are almost there.go to ports and pins/inputs/ thc up choose a unused input pin,thc down another input pin. what i use is a arcade joystick which has 2 micro switches.connect to your selected input pins. while i have thc arc control for plasma, i use the manual move for oxyactlyene cutting.
