Title: How to make z tool cut deeper on the fly.....
Post by: screwhead on September 28, 2012, 11:01:45 AM

I am cutting wood products, so there's little concern for tool breakage.  I set my Z to touch the work stock before I start cutting.  However, at times due to mild warping, the toolsdoes not fully cut through the work.
Other than changing the length in G code to a longer depth,  is there an easy way to do it with Mach on a temporary basis?  I know I can "fake" the z number before regenerating the toolpath, but then I cannot ever use the "go to zero" because the tool would dig into the surface.
Thanks in advance.

You can fake the 0 as you refer to. You need to set your clearance higher and man the Estop.

All gcode relates to a NON changing surface. There is no easy way that i am aware of to address a changing surface.

It may be possible to use the Torch Height control intended for Plasma, you can set the max distance allowed to jog and can set up hotkeys to do the jogging but whether its a good idea or not I will leave that up to you to decide ;D
