Need Help!- "Ref all home"

[watsonstudios]

I've had this problem before but forgot how to fix it. It's been almost 2 years since running my machine and I'm having to re-learn Mach.

The problem is: I'm running 3 axis'. I have 2 steppers on my X axis so I am using X and A together in Mach3. When I "ref all home" it homes Z then Y then X then A but I don't have a limit switch on A - so it tries to ref A and messes up my axis. Before, I could get X and A to ref together and both steppers would turn together - now, both turn to reference X (good) then only A turns to ref A(bad) how do I fix this this?

Also, all my settings are the same in Mach as they were when everything was running correctly. Am I missing something, does it have to be in machine coord. mode?

Change the button script to this. Operator menu, Edit Button Script.

DoButton(24)
DoButton(23)
RefCombination(9)

I'm not quite sure I follow you. I went to operator menu, there was a vb script editor but not an "edit button script". I did find a file in the Mach folder called m1076.m1s and opened it with vb script editor bit there were no "DoButton" lines in it.

What version of Mach3 are you using? If an older version, you may need to edit it with the older screen designer, Screen3.

I have the same problem with the REF ALL HOME command. I'm using both Y and A motors for the Y-axis. That command moves my slaved A-axis motor separately from the Y-axis motor (they move together only with manual jog). Here is a screen-shot of the Operator > Edit Button Script menu. What's necessary to do in order to run my A and Y motors always together? Thanks

Wow, thanks for the quick reply I will try this one once I go to my workshop and hopefully this will fix my problem.

Unfortunately, even that code was not able to fix my problem and Y & A axes still move separately ONLY when I activate the REF ALL HOME button. Is there any other way to correct the things?

I did a little trick by jogging the gantry just one millimeter away from the Y/A home switch activation, so when the program activated my Y-axis motor (the slaved A-motor was "dead" at the same time) the gantry's left side moved only ~3 millimeters further and then moved back to the original (set by me) position. I also used a black marker to ensure that the gantry will return to the exact position. This is how I cheated the program after I was unable to do the things via the "software way".

If you only have a single home switch, go to Config>General Config and check "Home Slave with Master Axis".

I double checked anywhere but I still can't see any check box in my General config menu regarding slave and master axis Here is a screen-shot of my current (Mach3 DEMO) configuration:

You need to get a newer version of Mach3. It was added a few months ago.

Well, I suppose this is the main problem with my Mach3 - it's an older version. I have downloaded the demo from www.machsupport.com few months ago and now I see a newer version there. Thanks for the advice, I'm going to install it and obtain a license soon I hope it won't ask me to reconfigure everything after each update.
