plasma torch hight controll

[jcoldon]

masso can you guys please explain to me the masso plasma cut process

1 torch touch finds material height. 2 torch rises to pierce height . torch fires 3 pierce delay all in g codes ?

4 then after pierce height torch lowers to cut height.. some time during this cut height process the THC takes over correct ? or you sending gcode to turn on thc ?

if so how do we put a delay to stop the THC so cut height can start first to allow voltage to settle . I assume the system does allow the cut height g code to be used after pierce height delay .. or are you allowing the g code to turn on and off the thc? how would I put a thc on delay it be used on every cut after pierce delay

if the arc ok signal from thc is delayed what will happen ? does masso need arch ok to do a pierce or just to move off the pierce delay to allow x y z movement to cut height

I ask this my thc can delay arch ok

. second how do I put a max min thc height limit on the z movement when thc is active so if voltage goes stray it wont lift the torch off the able or lower it

and burn up tips

last question can a plasma masso get a software load and make it into a mill version

thanks jeff coldon

yes you can change to mill version any time, just email on support with your serial number and we will email the software.



The gcode should follow this sequence:

1. goto X, Y position
   
2. move Z axis to do a touch using G38.2
   
3. move Z to piercing height
   
4. start plasma using M3
   
5. move Z to cutting height
   
6. switch on THC using M667
   
7. cut material using any X and Y movements.
   
8. switch of THC mode using M666
   
9. switch of plasma using M5

ok now we are getting some were how would I delay #6 that way when at cut height the voltage will settle before #6 THC goes active

also how do you set min max THC z height settings incase voltage goes a stray lifts torch off the table burns out tip or drives the torch in the cut

if we could do the above features for now I see thc running way better

Why could you not put a G04 between #5 and #6. Then just state the dwel you want with a P command. P is in milliseconds so G04P500 is a 1/2 sec dwell.

wait a sec does MASSO support macro programming. That could be a real handy feature with the plasma. So would a a sub program. Just write a custom sub program that has all your custom tweaked torch startup stuff. Then just call that up every time you need to start a cut.
