Hey All
I have a machine that has 2 drive motors on the Y axis and I am running Mach 3. I was wondering if any one out there has a script (that works) that can both home and square up this axis. I have home switches on both sides just cant find a script to utilize them. If anyone can help it would be greatly appreciated.
Thanks
If one motor is slaved to the other, Mach3 will automatically square them when homing.
Make sure that in General Config, "Home Slave with Master" is NOT checked.
If it doesn't appear to be working, you may need to modify the homing script to use RefCombination for the slaved axis. There's info on modifying the homing scripts in the back of my 2010 Screenset manual. http://home.comcast.net/~cncwoodwork...0%20Manual.pdf
Thank you Gerry for your reply ..... I have the two motors slaved in homing now which will drive both motors at the same time to a single switch.... The problem with that is if one drive is off for some reason the homing will not square the bridge ... i was hoping someone had a script that would home it a slave ... then back off and drive each side to its own switch to square the bridge.
I don't believe there's any way to do that in a script. You'd need to toggle the "Home Slave with Master" setting, and scripts don't have access to it.
I have found a way ..... dual drive home.
Y and B motors are used for dual homing. If the motors are not slaved in software then they are slaved in hardware. You will need to rewire the drivers so one is contorlled with Y (step and direction) and the other is controlled with B.
A home switch for B must be added as well.
The homing can be done with a RefCombination() and if you wanted to do the Y and B it would be done like this
X=1
Y=2
Z=4
A=8
B=16
C=32
Y+B = 2+16 = 18
RefCombination(18)
Add to VB script with "edit button script"
-------------------
BEFORE-
DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )
DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)
------------------------------------
AFTER-
DoButton( 24 )'RefZ
RefCombination(18)'Home Y and B axes
DoButton( 22 )'Ref X
DoButton( 25 ) 'Ref A
DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

Take a look and let me know what you think./ Thanks to Phil at PDJ INC for the program.
Sorry, I could have given you that before, but I misunderstood what you were asking for.
You can remove the DoOEMButton 133-135 portion, as they just zero encoders, which you most likely are not using.
Thank Gerry
I know this thread is mega old.. but i have a problem using dual x axis.. i have a chinese ZK motion board, and had a dula homing option in its own settings... this how ever doesnt seam to work... and after altering the 2010 homing macros i still cannot get dual homing (squaring) to work...i have 2 motors X+C and 2 homing switches X + C
general config is set (unchecked) not to home Slave with Master Axis
i have 4 options on my controller plugin
1 No Homing (non of the homing buttons seam to be active)
2 Single Return no pull off (each press seams to jog 1mm toward the home switch)
3 Single Return pull off (each press seams to jog 1mm toward the home switch)
Dual Return home (X + slave home together (at the same time as on eaxis)
i have edited the homing macro (currently m888 For testing) to use RefCombination(33)
but this still only homes it together not independetly (non squaring)
i have tried slaving the A Axis instead and that made no change,
my conclusion is that the Controller is overiding the macros or doesnt run them as intended, but then the controllers own Dual homing doesnt seam to work either
any suggestions?
1) Try to find a newer plugin for your controller.Quote:
any suggestions?
2) Try a different version of Mach3. Many plugins work differently with different versions of Mach3. A lot of Chines controllers use plugins that work best with older versions of Mach3.
3) Buy a non Chinese controller that actually works.
thanks for the suggestions... i have actually just managed to find firmware update for the controller so i can try that tomorrow, i actually live in china now so its pretty difficult to buy Non chinese controllers, im very happy with the controller its self and it not a cheap $10 board, i was just hoping that maybe i made a rookie mistake with the homing macro (Screen 3.jpg) or overlooked something simple.. but if the maco looks ok to you then i must have to figure another way around the problem
