Scriber -Marking + 2 Oxy-Fuel Torch

Post by Bharat Autotech »

Hello ,
In my application of CNC Plasma Cutting Machine using ET10 Board & Raspberry pi4 ,I need to provide 1Plasma + 2 Oxy-fuel Station + 1Scriber Marking. On operator Console panel I will be using momentary switches for torch lifters. 4 Switches viz 1. Plasma, 2. Oxy-fuel, 3. Oxy-Fuel, 4. Scriber Marking System. Kindly advise how to configure 2 stations of Oxy-Fuel torches and Scriber,what kind of program input required for Scriber!

Good morning. Some documentation wiki information on the scriber on/off procedure: http://docs.pv-automation.com/examples/ ... 6p#scriber

The scriber is turned on/off using the M72/M73 commands in your G-code. Don't forget to set your output pin for the scriber in the pins.h file.

We've had a gas profile implementation with two oxy-fuel torches some time back:

If you'd like, we can share this custom profile with you - bear in mind however that you will have to set it up from the ground up since the settings are most likely different from what you currently have.

In general, complex setups such as this are accommodated through the use of PLC procedures. Custom PLC procedures allow for flexibility through custom code, but they do require you to have some prior knowledge of programming.

PLC documentation: http://docs.pv-automation.com/plc/plc

A lot more PLC examples and sample code is available if you search for PLC on our documentation wiki: http://docs.pv-automation.com/myCNC?do= ... Aplc&q=plc

Hello Ivan,
Kindly see below youtube URL example of combo Plasma + scriber marking.Related to this I have 2 questions,please help out!

https://youtu.be/zl9YA1EaxKE


1.What kind of program file (dxf/nc/cnc file )is required to differentiate between Marking and Plasma/Oxy-fuel Cutting?Are there different layer for Marking & Cutting?
2.In my application Oxy + Plasma + Scriber these 3 processes are used.Is it possible to use combination of Scriber + Plasma or Scriber + Oxy-Fuel?

1) In order to differentiate marking and plasma/oxy-fuel cutting, you simply use the M72/M73 codes in your main G-code file to turn marking on/off. No separate file is needed. If you are importing a DXF file instead of a G-code (.nc, .txt, .cnc, etc) file, that will require you to have a separate layer for the marking process which you will then assign as Marker during the import (the other layer will then be assigned as plasma/gas depending on your application). This layer should be drawn in your software of choice, we use Inkscape, but you are free to use any program with a proper DXF file output.

2) It is possible to use a combination of these technologies.

In order to switch the main technology from plasma to gas and vice versa, you can use the Change Technologies button in your menu (available both in the X1366P and X1366G profiles):

Marking is built into both the Plasma and the Gas profiles so regardless of which profile you are currently on, you still have access to the scriber. Effectively, you will run some job with plasma cutting, then, after the job has been completed the plasma torch will be moved up to the safe parking position and you will switch the technology to gas cutting. Then, after the gas cutting job is done you can switch back to plasma cutting.

Here is a video of a client of ours using a marking / plasma cutting setup:
