Dual Axis homing
« on: July 01, 2012, 10:03:20 AM »
Hello
I try a gantry milling machine with a dual X axis (C slave) to homing.
All axis has its own reference switches. Z and Y works well.
With the hook "Home with Master Slave Axis" will stop the X axis and moves the switch again free. (C Slave the same)
Without active "Home with Master Axis" adjusted the slave axis, but the X axis run over the reference switch.


Mach3R3.043.058W-33
PlugIn: SmoothStepper_v17f

Attached is the xml

How I have to set does the homing also works with the slave?

Regards
Philipp

Would you not be wanting to home the slave with the master anyway?
Its likely a SS issue if its not working right as homing is handled in the SS rather than in Mach.

Hi Hood

To align the gantry, (synchronise the two Axis) I have to disable "Home Slave with Master Axis" ?
It's run with the newest Plug in  :-\


 In the register "Homing/Limits" is a column with "Home Off." but with this values it's changed nothing.
I would like to going a little away from the limitswitch.

Ok I thought that was what it was doing when you said
"With the hook "Home with Master Slave Axis" will stop the X axis and moves the switch again free. (C Slave the same)"

Home Off is not to set a distance to move off the switch, it is there so you can enter a value if you home switches are not at Machine zero.

Hi Hood


Without the hook:
1. Z move up, Z switch, chang the direction move to switch OK (closed)  :)
2. Y move to -Y, Y switch, change direction  and move to the switch is ok  :)
3. X and C move to -X, X switch , both change the direction and move to switch X OK.   ???

        C is not checked the switch.

with the hook:   (1 and 2 are the same)
1. Z move up, Z switch, chang the direction move to switch OK (closed)   :)
2. Y move to -Y, Y switch, change direction  and move to the switch is ok  :)
3. X and C move to -X, X switch , X change the direction and move to switch X OK and immediately again -X over the limitswitch    ???
4.                             C switch , C Axis change the direction and move to the switch is ok.   :)
     
Anything in part 3 going wrong!

Ok I see what you are saying now. Probably best to look on the warp9 forum as I know there have been issues with slaved homing in the past.

I don't know what the SS does, but with the parallel port, when you check "Home Slave with Master", the slave axis switch is not used.

Hi

Yesterday we tested again and we saw, it was the old mach3 version still installed. We deinstalld and deleted all mach 3 programs and folders. and install the newest mach3 version with the ss plugin V17f.

Now it works fine. sorry about the confusion.
