Is it for the whole project, or just for one part (Say the outline)
EstlCam will basically do stuff like a slicer, using your DOC settings for your tool. There will be a series of moves where it plunges to depth, in increments of your depth of cut.
Let’s say you use 1.75mm as the defined depth of cut. You’ll see a number of moves (With a bunch of other stuff between them):
G1 Z-1.7500 F300
G1 Z-3.5000 F300
G1 Z-5.2500 F300
And so on. Say I wanted to change my code to do the same thing, but cut to 6.5mm. I could just increase the last pass, but that’s potentially bad news, since at some point I determined that 1.75mm is probably as much as I want per pass, and the last pass is not the one I want to plunge further than that.
I would probably do a bunch of global search/replace.
- Replace “G1 Z-5.2500” with “G1 Z-6.5000”
- Replace “G1 Z-3.5000” with “G1 Z-4.3333”
- Replace “G1 Z-1.7500” with “G1 Z-2.1666”
(Somewhere in my brain I’m thinking “:g/G1 Z-5.2500/s//G1 Z-6.5000/g” – too many years using vi)
Well, maybe I’d make the numbers divisible by 0.0025 (One microstep at 400 microsteps/mm) or just round to 2 decimal places as being close enough. This will change your depth per pass
If instead you want to do only one part (say the outline) you would have to segregate that portion of the code (Fortunately EstlCam separates out parts, holes, drills etc into their own chunks, so at least you’ll have comments to figure it out) and then do the same thing. Remember that if you have holding tabs, there will be Z moves in the middle of everything, not just the start and end of a pass.
Can you do it? Well, okay… Should you do it? Probably not if you aren’t 100% sure you can deal with the increased DOC
