Title: homing not zeroing axis?
Post by: howling60 on May 14, 2007, 07:27:23 PM

Hey all...

my mill has recently developed a new feature!  of course, this could have very easily been accomplished by someone "fat-fingering" the touchscreen... 

but, here it goes...

started up the machine today and re-homed it.. we utilize prox switches for home switches... with homing speeds @ approx 6 ipm (if that)... @ activation of the prox, the machine reversed direction, and backed off the switch.  I looked @ the DRO, and it did NOT read 0.0 as I would expect?  I went through the entire homing process, and this occured with all 3 axis.

I fortunately, make a backup of all files on the mill every time i work on it, and so i backdated the entire M3 directory to 14 days ago, when i last considered making changes..   Powered up the machine, and it homed just like it was supposed to...  with an axis of 0.0 after the homing.

Am I just missing something really stupid here?  I checked through all my notes, and don't see that I have done anything to M3 since 4-30-07 (when my last backup was), but as i mentioned above, and operator could have "fat-fingered" something on the touch-screen.

any help would be great if someone could possibly help shed some light here..

oh, machine is running Win2k, latest release of Mach3

thanks!

So,

after doing more testing, and using my M3 directory from 5-14-07, I dropped in my XML from 4-30-07 (last backup point), and the homing was working perfectly fine...
I had just wanted to confirm that this was a setting issue, and not an "external file" issue that might be caused by a macropump, or an m-code/etc...

Hello Nate

Did you check the home/limit page for the auto zero?

Please check that the machine coordinates are set to zero. It will not zero the fixture offset on homing.
Thanks

it was in machine coordinates, and i did double-check with the "machine coordinates" button below the DRO's...   I will have to check the "auto zero" in the homing screen...  i don't know how/when that might have gotten changed, but it is very possible...

btw, thanks for the assistance on the machine yesterday Brian.. much appreciated...  it's been up & running the better part of the day, making dust outta foam :)

We may have to get some video of it running someday ;) We will not talk about what you are making  8)

we can most likely do that!

speaking of what we're making..  started on those *other* foam cores yesterday.. talk about entrancing to watch!  found myself leaning closer and closer with some drool hanging out of the corner of my mouth  :P
