Im doing some work on my 4th axis that requires many turns, basically like a lathe would but with an endmill. Here's the issue, after running code like this, my A axis has made many rotations, sometimes 30 or more. Afterwards I want to get my A axis back to machine zero and this takes forever. My machine doesn't use home switches, it just has a stored location that machine moves to for home. If I send the machine home, it moves very slowly since the A axis has to unturn all those rotations. The other thing I can do is move the machine to x,y,z home position and then ref all home to zero everything including A without having to unturn all those rotations.
Is there a better way to handle this? Like simply enter a code to zero A axis machine coordinates where it sits? If I can't do that, is there anything else I can do to make this easier? Typically I'm hand writing this type of code and use multiples of 360, so having it first move to a consistent angle isn't a concern since it's already there, just need it to zero in place

Ref A

Ref A

I can put in a line of code "ref A"? Or there's a button somewhere? If it's a button, I haven't seen it, only ref all

There's a button on the Diagnostics page.

Ah, perfect. Thanks!

If I wanted this to happen automatically in a program, how would I go about that? Could i do it with a simple macro?

I found the oem code, 1025. How do I activate this code in a macro? Still very new to scripting

Excellent! Thank you

Ok, wrote the macro, named it m100 (tried as m100 and m100.m1s). When running it in vb editor, it works as expected. When using it in gcode or by itself in mdi, does nothing.

Ok, renamed it m3, works now. How do i know what m codes are useable? Originally picked m100 because it wasn't in the m code list and was easy to remember. Any specific reason why it didn't like m100?

Try values over 300. I don't recall which are reserved. Over 1200 might be safer.
If you use M3, then your spindle probably won't start any more.

Not sure what kind of results you'll get running it from g code, but add this after it.

Crap, not sure why I didn't remember m3 was spindle on. Indeed the spindle will not start. How do I get it back? What does the m3 macro look like? Odd thing is, I saw the m3 on list of my macros, I opened it and it was blank, so figured it was for nothing so used it for the ref A. What should be in there?

Ok, figured it out. Looked at m4, same but cw instead of ccw

Saved the ref A as m1200. Seems to work fine without the while wend and I don't think I overwrote anything this time. I think I should probably start saving xml before messing around in the future

I believe it's DoSpin(CW)

Yep, it is. Figured it out by looking at the m4
