Run from here.......

[gurob]

Hi my friends

I have a CandCNC Bladerunner AIO, using Mach3 and Sheetcam on a Plasma Table.

I have the Floating Head system, and use MP3000 post.

So, my GCode has many G28.1 G92 codes to set the height for the start the torch.

So far so good, it works perfectly, less when I have to STOP the code to change the plasma tips when runing a long code, or other reason.

So I back the code some lines, and click RUN FROM HERE.

The program scroll since the begining, takes me about 5min when in long code (10.000 lines) and change the Z DRO as it passes through the G28.1 G92 codes, and I have to REF Z all the time. It makes me furious.

Does anybody have the same issue? Is it normal in Mach3? I would like just to choose the line I want to start, click RUN FROM HERE, and RUN button. Simple like that. I dont want that Mach3 passes for all the lines before I can continue the program. You can imagine in a 20.000 lines program how much time I spent waiting.

Does somebody can help me?

Thanks in advance.

Use "Set Next Line", then Cycle Start instead of Run from Here.

Or put an M1 stop at a couple of places in the program so you can check the tip.  Do an M1 followed by a Z retract.  Check the tip, replace if necessary, then hit cycle start.  I do this on long programs and usually put an M1 at 50,000 line intervals.

You need to set up a function button to run the TOM (top of material routine) that the CandCnc units use with the floating head.

Then when you need to restart move to the area to restart then run the TOM routine to set the Z ref.

Select the line you wish to restart on then press SetNextLine and then START , AND be ready to refire the torch manually as the torch approaches the restart point.

You may want to restart a little earlier to give you time to be ready to refire.

I have a Auto restart/Refire routine in testing now along with a lot of cool functions for Plasma using TOms new PN200 pendant.

Just a thought, (;-) TP

SetNextLine is what I was looking for. Thanks everybody who told me it.

BR549,
what kind of functions will you put on PN200? I use a XBOX360 wifi controller as pendant today.
I will be greatful if you tell me how to make a macro with the TOM routines, then I can use the macro in a button of my XBOX controller.

'CCC TOM Routine
Code" G28.1 Z0.500
Code" G92 Z0.0"
Code" G00 Z0.1370"  ' The Z value is the amount of switch travel
Code" G92 Z0.0"
Code" G00 Z0.500"
While Ismoving()
Wend
End

Does anybody know where I can change the travel speed used by Set Next Line?

[BR549]

I believe that the SNL uses the current feedrate that is set.

I thought it too, but it is not. I was running my program at speed rate 2400mm/min and SNL was moving the torch at 1000 mm/min. Too slow!

SetNextLine does nothing to the feedrate - it will start running from the line you specify, using whatever feedrate is currently in effect.  I use it all the time, and have never once seen it do anything different.
