Re: [Emc-users] Where are Home and the Current Co-ordinates stored?

Thanks for that, so far, and for clarifying that #5420 is not absolute. This is a big step forward. Now you have me intrigued... so how do I get absolute? I had imagined everything would be absolute internally, then offsets would be added to get current workspace co-ordinates, but if G28 and G30

Re: [Emc-users] Where are Home and the Current Co-ordinates stored?

Ok. That's good info, but I am slightly confused by the wording of that and the previous page you directed me to. In 7.1 Numbered Parameters, it says: 5420-5428 - Current Position including offsets in current program units (X Y Z A B C U V W) But in that last page 7.6 System parameters, it says

Thanks, Andy. I didn't realise the INI file worked that way. I know about G54 etc, but if I want to read the current co-ordinates, where would I find them? Or do I simply use G28.1 or G30.1 then work with the values that puts into 5161-6? I wanted to do it without having to issue a command, alth

[Emc-users] Where are Home and the Current Co-ordinates stored?

I understand G28 and G30 and their use of the parameter blocks 5161-6 and 5181-6 Where are the HOME co-ordinates stored? Where are the Current Co-ordinates of the Controlled Point stored? In either case, I assume these will be expressed in absolute machine co-ordinates. Thanks. Marcus -

[Emc-users] Step & Direction for use on Servo Amps

Can the stepper motor 'step & direction' output from EMC2 be used to run a servo based system that has step & direction input amplifiers where the servo motor encoder feed back goes into the amp and not EMC2?   I believe the Yaskawa Sigma II amps can run in this mode.   My thought was to build

Yeah, I have one of the XYZA ones - works incredibly well. I did get the "breakout board" to ensure that I got the 5v, and the EStop functionality for it. (I started with a USB joystick, but I'm programmed to turn knobs to make things move; joysticks do not do that for me) John A. Stewart.
