My foldable plasma table

It’s working!!

The only problem I have right now is the cheap plasma I have will not fire reliably! I’m hoping that adjusting the spark gap will help it work better. 

now for some questions about plasmaC. 
1. how do I erase/unload g-code? I can’t find any buttons?
2. How can I move the cutting to not start in 0.0.0 and offset it to a free spot on the plate? I thought that I could move the work coordinate system, but couldn’t find any button for that either.

“You can not, this is not Mach3 !
Maybe QtPlasmaC has it but i never ever found a reason for that to exist.”
I’m totally new with CNC so I haven’t tried any other controllers.
Now when I’m trying to learn I have used  the shapes to make test cuts, and I make small changes run it again. Then it should be nice to flush the g-code without the need for homing it again. But I guess that when I’m fully learned it will not be necessary.
I’m so happy right now to finally have the plasma table up and running! Couldn’t have made it without your fantastic support!! Thank you! *kudos*

phillc54 >> How i understand it work is that if i load G-code to the machine. There is no way to load a new project without closing PlasmaC. So for every new project i have to restart plasmaC and do the homing. If there was a way to clear the G-code without closing PlasmaC then i don´t need to re-home. This will be no problem, it was just me woundering how it works. T

Ok nice! How do i do that? Will it automatically flush the G-code when loading new G-code. I have only tried the inbuild shapes to test the plasma, and i haven´t found a way to erase everything.

Thank you. I must do something wrong then with the shapes
