Return to part zero after cut

[Skrotskalle]

I have a annoying problem I hope someone can help me with.
After finishing a cut the torch returns to home position (machine X and Y zero). This is really annoying, since I use a watertable and when cutting on a smaller sheet on the middle of the table, the torch will run over uncovered part of the table when the post flow is running splashing water all over.

I am running the latest development version of UCCNC with the Neuron plugin and a NeuronLite THC.

Is there a setting some where to choose between return to part zero or machine zero?

The machine goes where the g-code tells it to go, so this would be a setting in your CAM software.

Here is the g-code from a small part I cut today. I am using Sheetcam by the way.
Last entry is M05 M30 and the there is no move command after that. So why does it return to home position?

have a look in your M30 macro

My neuron M5 is as follows:

Code: Select all

int time = 0;
exec.Stopspin();
while(exec.GetLED(493))   //wait torch retract
{
   if(++time == 50)   //if more then 5 seconds torch will not retracted, return
   {
      return;
   }
   exec.Wait(100);
}


My neuron M30 is as follows:

Code: Select all

//M30, this code is executed on M30 after program end and file rewind


i.e. it is default / not been edited.

Just checked the marcos and they are the same as yours. They have not been edited.

Hi Marcus,

I single stepped through your code in the demo version of UCCNC and it did exactly what the gcode told it to do.

I can't find a setting in UCCNC that would make the axes return to zero after the gcode is complete.

Maybe try single stepping your gcode doing a dry run (torch not on) and see if it still happens. I'm wondering if this is something to do with the Neuron plugin.

I will try this later. I am also thinking it might have something to do with the Neuron plugin. Because I did not have this issue before switching to the NeuronLite THC and Neuron plugin.
I will shot Andrew an email if he doesn't chime in here.

Hello!
Your code is executed as it should. There is no return to part zero. M30 just rewind gcode file.
The plugin doesn't do that either.
You can send me the profile file, I'll check it myself.

[Skrotskalle]

Here is my profile.

I am run with your profile - no return to the part zero.
But I see in the macroloop you have a M25100 macro. Have not this on my machine, but You need to check what the macro is and what it does.
Also I think 20.269 pulses in mm value is low. Try to setup microstep value for the stepper drivers for have 200-300 pulses in mm.
In any case email me and I can login to your machine for help too.
