Hey guys,
Anyone out there familiar with planet cnc and sheet cam? Or either? I have set up my plasma with a floating head with a limit switch located on the bottom of the axis (will need to build a shield for it or move it).
What I’m trying to accomplish, is having the plasma torch touch off, zero itself, then raise to cutting height before starting. I’m also using a thc, but that’s a whole 'nother story.
I believe I need some g code like this inserted before cuts.
G28.1 Z.50 ’ references the head down until it trips the switch
G92 Z0.000 'Sets that point to ZERO
G0 Z0.250 ’ Moves the head UP the amount of the head travel + switch movement
G92 Z0.000 ’ Sets that position to ZERO, that will be TOP of the material,
G0 Z.100 ’ Move the head up to a clearance position
Not every cut will need this though, such as small holes located next to each other. The unintended benefit to this will also be that the program will have longer pauses between cuts, giving muy composite time to keep up and not be running into duty cycle limitations of my plasma torch.
Any advice would be greatly appreciated. Thanks.
Mark
