Hey everyone I am in the process of building an air scribe plate marker for my table. I understand the mechanics of it the hose routing and how to wire it. I’m just having a hard time figuring out the sheetcam and Mach 3 programing part.
I am using pin 16 on my break out board to a relay to trigger the solenoid to power the air scribe. I created a new tool in sheetcam made the tool number over 100. Now I need to get into post processing and I am getting quickly over my head.
I’m using a premiere plasma table and have that selected on the post processing section. All of the research I have done everyone seems to be able to select there machine with the plate marker from the drop down menu because I’m assuming its an option with there machine.
Is there a way I can add the plate marker to the premier plasma post process I have selected?
Or can I choose a generic plasma cutter and plate marker from the drop down menu? Id assume I can’t do that because id loose all premiers settings

Re: Plate marker post processing help
I don'd have a copy of the Premier plasma post processor. Could you send me a copy. I'll take a look and see if they have implemented air scribing.

Re: Plate marker post processing help
Thank you I messaged you a copy also.
excuse me if I don't use the correct terminology I know nothing about post processing or g code.
again what I'm trying to do is create a plate marker tool in sheetcam that activates pin 16 through mach 3
function OnAbout(event)
ctrl = event:GetTextCtrl()
ctrl:AppendText("For use with ProTorch CNC Plasma cutting tables")

Re: Plate marker post processing help
In SheetCam go to Options->machine->post processor and select the 'Mach3 THC with scriber' post. Next click on the 'Edit post' button.
Near the start of the file are a number of configuration options. Use these settings:
useRef = true
refHome = false
refDistance = 150
refFeed = 500
switchOffset = 5.08
scriberX,scriberY,scriberZ to suit your scriber. The are the offset of the scriber from the torch tip.
scriberAxis = nil
This assumes your scriber is mounted to the Z axis on a slide that goes down when the coolant output turns on. In other words, pin 16 needs to be configured as the coolant output.
