I cut sheet acrylic & zero to the spoilboard. Occasionally I won't get a cut fully through the material & I need to adjust Z0 slightly. To do so, I add what I think I need (usually a few thousandths) to the Z DRO in CONTROL. So if for example Z is sitting at 1.620", and I thought I needed to cut .005" deeper, I enter 1.625" in the Z DRO and Ctrl-Enter. I'd like to have a macro written for this. Either a simple one that changes whatever the current Z value is by .005", or a fancy javascript macro that prompts me to enter a value to adjust Z by. I'm looking for somebody who can create this macro for me (there was a time that I might have been able to do it myself, but not now). If any additional info or clarification is necessary, I'll provide it. Thank you...
This should mimic what you're doing by hand (Create a macro, name it & copy this into the GCode window): G20 G90 G0 Z1.620 G10 L20 P0 Z1.625 Explanation: G20 - make sure we are in inches G90 - make sure we are in absolute mode G0 Z1.620 - rapid move to Z 1.620 absolute, assumed to be a 'safe' Z height - please change to suit. G10 L20 P0 Z1.625 - change the offset of the current coordinate system such that the Z position is now 1.625" (change to be whatever you want the 'new' height to be). N.B. I haven't tested it!
