Problems with Ref All Home with Dual drive setup
« on: August 09, 2012, 10:28:16 PM »
Hey guys,  let me first say that my machine runs just fine when cutting.  This problem only exists when trying to do a Ref All Home.  I run a dual drive Y axis  (Y & A).  When I do R.A.H., only the Y axis is searching for home.  'A' isn't even turning at all.  It's like it's ignoring the Slave axis function and my gantry starts to twist.  I have to kill it so it doesn't stall out my motor.  What am I doing wrong.  I can't seem to find what I'm missing here.

Thanks for any help on this.

Make sure "Home Slave with Master" is NOT checked in General Config.

Hey, Ger... your a genius.    Mine was actual unchecked before I did anything.  I had to check mark it.  Works great now when I "home" it.  Bumps the switch and then backs off.

I have one last question.  Home works great now.  My limits function work too(except...).  I force the machine to hit the limit and it goes to E-stop mode.  However, Is it supposed to back off as well when it bumps the limit?? Only way I can go active again is to manually turn the lead screw so that the bearing block moves away from the limit switch.  I would like it to do the same thing that it does when it's homing.  Or can't it do that?

Thanks much.

Well after much searching, I think I found what I was looking for.

"2) On the Settings screen, turn ON "Auto Limit OverRide". This allows you to reset the E-stop and move off of the limit switch with manual motion control (arrow keys).  "

^^  I haven't physically tried it yet.  If someone could confirm for me that this is what I want, great!  Basically what I want is, if a limit switch is tripped because of over travel, I want to be able to take my handheld MPG and back off away from the limit switch.  I don't wanna have to manually do it by turning the lead screw. That's a pain especially for my Y axis because it's dual drive.  I then have to re-sync Y & A.

Thanks.

If the slave and master have their own switches, then it should be unchecked.
If they share a single switch, then check it.
