Idea regarding homing for selfbuild CNC was created by daniel79
Hi!
first a question:
I tried the different GUI for EMC2 and in one GUI homing was done for all axes the same time. Is this possible in axis too?
second an idea for selfbuild CNC Mills like i have:
Is it possible to diplay the homing difference between two homing processes:
The idea is:
1. homing
2. running a projekt
3. homing again and if theres a difference there will be a window with the differences inside so that i can see that i have to fix/change my DIY mill

Daniel,
In Axis you have to specify the home sequence in the ini file.

Hi John!
I think this is i have to look for:
HOME_SEQUENCE = <n>
Used to define the "Home All" sequence. <n> starts at 0 and no numbers may be skipped. If left out or set to -1 the joint will not be homed by the "Home All" function. More than one axis can be homed at the same time.
right?
What would be the value I need for homing all 3 axis the same time?
And has anybody an idea to my second question, idea. Any way to see the difference when homing?

Hi!
Sorry for my late reply! I had a lot of work the last weeks.
Homing at the same time works perfect! Thanks John!
But what about my second idea? Is it possible to read somewhere if there was a difference between the estimated and the real homing-point?

It was proposed on the mailing list, and there was some discussion.
I found a way to do it in HAL using existing functions.
thread.gmane.org/gmane.linux.distributio...er/20074/focus=20086
Chris Radek has added a hal pin that reports the homing error to the latest 2.5~pre build.
