Dynamic axis minima and maxima
-
Hi,
I'm using the Duet wifi for my cnc router and its working great.
When I start a milling operation, I set the machine's zero point to a suitable location on my stock. Currently I'm just using G92 X0 Y0 Z0 to set my zero point. What I would like to do also is set the axis minima and maxima according to the current position.
I'll give an example of the steps I want to take:
- Let's say I have a machine that can move X500 and Y500
- I home the machine
- I manually move the machine to the spot where I want to start machiening (lets say x100 Y100)
- Then I want to call the macro which sets the minima to X-100 Y-100 and X400 Y400 for the maxima
- After that I want to use G92 to set everything to 0
Is it possible to do this?
-
It maybe easier to leave the machine coordinaye system constant but use tool offset to set a specific point within the macine to (0,0,0)?
G10 P0 Xa Yb Zc
...will offset tool 0 relative to the machine coordinates.

Isn't this what the work coordinate system is for?

Thanks guys, I can't believe I didn't see this in the GCode page, I went over it a few times already. I'm going to give this a try tomorrow

@bearer good shout. I'm coming from the v0.6/0.8.5 side of the fence so need to bodge a few things like that!

I got lucky;)

@bearer I got a chance of testing it today and the work coordinate system works perfectly, this is exactly what I was looking for. Thanks!
