DTHS Issues
« on: July 25, 2014, 08:17:18 PM »
Recently acquired a plasma cutting table running Mach 3 and I am just trying to get the table to jive with the computer.  I am attempting to run the G-code and I keep getting a DTHS setting issue.  I believe this is a digital torch height setting but I am very new to this whole thing and can't figure this out, please help!

Never run Plasma but if you attach your xml I will see if I can find anything obvious.

Thanks for the reply, having a different problem now.  All I want is for the table to run through a .tap file I create in sheetcam and open with Mach3.  The table responds to Mach3 when I load the test.tap file but will not respond to a file I create in Sheetcam with the same .tap extension.  Is there a setting somewhere that is not right or something that needs to be set before the Mach3 program will run the file I create?  On the G-code box it shows activity as if it is running through but the table doesn't do anything.  Also, there is no image of the cut shown in the preview box on the right that shows the xy axis.

When you attach your xml, if you also attach your problem code I will take a look.

N0010 (Filename: Drawing1.tap)
N0020 (Post processor: ldr dthclV.scpost)
N0030 (Date: 26/07/2014)
N0050 F1
N0060 G53 G90 G40
N0070 G00 X0.0000 Y0.0000 Z0.6250
N0080 S900
N0090 M22
N0100 S10 (DTHC is off)
N0110 M22
N0120 M05 M30

Status bar shows that DTHC is off, and I noticed when the test runs it shows that the DTHC Min cut lenght is on and set at 1 units.  I think this may be a clue.

That code is doing nothing or at most moving to XY zero and Z-0.6250 at rapid speed and that is all, if you are already at that point then it will do absolutely nothing.

This is the G-code that my created drawing brings up when I open it in Mach3.  I'm not familiar with G-code yet but it would seem that there is something going wrong between the creation of the file and opening it in Mach3.  I apologize for my ignorance in this field but I am just trying to get any information to get started I can and I appreciate your time.

Mach will only run the file it is being given, if that file is essentially blank then Mach will do nothing.
If you open your file you created out with Mach, in notepad, you will see it is exactly the same.
I have never used SheetCAM so cant help with it but looks to me like you are not defining the toolpath in sheetcam correctly or possibly you are using the wrong post processor in sheetcam.
