Re: [Emc-users] cnc axis "Touch Off"

well, I am comfortable with matrix algebra, but it's probably easier, more practical, to just do that part in freecad or so, and use a separate g code file for that. I was just wondering  what these different coordinate systems are, what they are used for. On 9/11/20 9:26 AM, dave engvall

Re: [Emc-users] cnc axis "Touch Off"

IIRC some controls have a switch to do this.  Also I think you can flip the sign of one axis and get a mirror image but the sense of the cut (climb/conventional) also flips so unless your machine is pretty tight dimensions may also shift. I've always done this the hard way by going back to the

Re: [Emc-users] cnc axis "Touch Off"

Hello Andy, That is interesting, I should learn more about these coordinate systems.  From a math/geometry perspective  there nothing that could keep you from translating, rotating (and even more weird transformations)  a geometry into a custom one. However in an implementation, of course,

ah ok, It sounds like the coordinate systems in essence are the same,  they just have a different origin, for all the other parts,   it's just the same thing, just translated and/or rotated for another part? Ron On 9/10/20 8:04 PM, Jon Elson wrote: On 09/10/2020 08:28 PM, R C wrote: I

Re: [Emc-users] cnc axis "Touch Off"

yup,  that's why I noticed too.  I thought "touch off" would be more like "this is (0, 0, 0)"  and just hit that button once... I guess I got lucky a few times. On 9/10/20 5:28 PM, Dave Matthews wrote: That is how I do it. There are three radio buttons, one for each axis. It defaults to

Re: [Emc-users] cnc axis "Touch Off"

That is how I do it. There are three radio buttons, one for each axis. It defaults to the last axis moved which is usually z. Dave On Thu, Sep 10, 2020, 19:01 R C wrote: > I was just playing with it a bit, > > > I have the idea, that , like homing is done per axis, "touching Off" is > done
