AFAIK Air scribe is controlled pneumatically. You don't need to know where Z is because in pneumatic circuit you will have only 2 positions. Top Up and On The Plate.
Take a look on https://www.youtube.com/watch?v=EPgbngKA0qQ
You will see that you don't have to concern about this

Ha! I just found an interesting feature.... Retry times on plasma missfire.
Could you explain  this feature a little? Do you mean that if from various reasons i don't get arcok Neuron will try to start plasma how many time i choose to get arcok?
If so, it will be great!!!

General Mach Discussion / THC plasma button on mach3

« on: December 14, 2012, 02:13:24 AM »

Hi.
I own an CNC Plasma table.
I keep forgoting activate THC sensor button after Mach3 launched.
There is a way to activate automaticaly or remain activated after previous run?

Is there a way to dynamic control speed (with potentiometer) for plasma machine?

Show"N"Tell ( What you have made with your CNC machine.) / Plasma table ohmic sensing

« on: October 19, 2012, 05:15:40 PM »

I have Diy plasma table with capacitive sensor. Main problem is when machine is cutting on sensor ring is sticking dross, so i have to stop the cutting process and clean sensor ring just because sensing is not working precise or not workin at all.
Is very annoying when i have to cut thicker sheets because i have to clean sensor ring more often.
Can anyone build his own ohmic sensing?
If yes can share informations?

General Mach Discussion / sped between cuts

« on: February 01, 2012, 12:49:00 PM »

1. Is there a way to increase speed between plasma cuts??
Cutting is at 1200 mm / min and mmmmmmving from one cut part to another is 1200 mm/min too
Can i change the moving speed ?


2. When i cut the toch is lifting from 1,5 mm to 4 mm. But if the metal sheet is bent then when not cutting the THC is not sensing the sheet and 4 mm in a point may be -2 mm in another point and torch is touching the metal sheet. Can I increase lifting height?

I'm using sheetcam an mach
For now i'm using Mach3 Flame with THC postprocessor
I have capacitive THC

General Mach Discussion / Controling multiple tools

« on: December 31, 2011, 03:45:31 AM »

I have my plasma table controled by Mach and i need to add laser pointer and a marker tool for drilling aid (3 different outputs)
The problem is the tools will "cut" in different places.
Is there any way to "move" the xy position according to each tool to do the coresponding operation as it should?

Thank you very very very much.
It looks like my problem was solved thanks to you.
I replaced ArcOK from THC with ArcOK from cnc interface i have at my plasma like it should be.
Then i used gcode provided by you with original M3 code and everything works perfect.
I purchased sheetcam a while ago but i didn't knew what postprocesor to use.
Thank you very much.

General Mach Discussion / Re: Mach3 and THC Problem

Sorry but i'm new to CNC.
I'm confusing ARCOK with THC ON (or not. I'm not even sure right now)
My THC send Up/Down/Probe signals to MACH wich i understand what they are doing and configure'it properly.
In addition it send the fourth signal wich tells MACH that torch is in right position and it's ok to fire the torch and start the cut and wich i configured in my system as THC ON
So in my inputs panel things look like this:


As i understood from previous posts ARCOK and THC ON are two different things and MACH will move my torch in position to start the cut, will fire my torch, but if there is no signal comming from plasma or relay that's telling mach the Torch on (ARC OK) then the XY motors will not move to run the program.
Right?
If so then how i configure ARC OK

The macro was provided for cutting is this:


Option Explicit
Dim PierceHeight, PierceTime, PierceTime2,THC_ON, THC_LED, OK, Z_Min_Height, Z_Pos
THC_ON = 123 'torch on screen switch
THC_LED = 24 'torch on screen led
OK = False
PierceHeight = 0
Z_Pos = 0
PierceTime = 0
PierceTime2 = 0
PierceHeight = GetUserDRO(1000)
PierceTime = GetUserDRO(1001)
If Not GetOEMLED (THC_LED) Then
Call DoOEMButton (THC_ON)
Else
OK= True
End If
Z_Min_Height= GetUserDRO(1003)
code "G31Z"&(Z_Min_Height)
While IsMoving()
sleep(100)
Wend
Z_Pos = GetDro(2)
Call SetDro(2,Z_Pos)
code "G4P1"
code "G1Z"&(Z_pos+PierceHeight)
While IsMoving()
sleep(100)
Wend
DoSpinCW()
code "G4P"&(PierceTime)
PierceTime2 = PierceHeight * 200
sleep(PierceTime2)

Ok. I understand.
BUT
As long the device send right signals to mach i'm thinking maybe is my fault because i don't know how to configure mach, or mach software has issues that cannot handle inputs from THC.
The THC is sending right signals to mach and mach recognize'it. The only problem is that X and Y axis is not responding after cut begins
