Zeroing A Axis

[findor]

Hello there,

I'm very new to CNC building and am extremely happy that I'm experiencing this wonderful (and agonising) process. I've got a little problem here; well not exactly a problem but I find it rather dumb and was wondering if anyone has a smarter tweak to it.

I am trying to zero my A axis after my cuts after 500+ degrees and I am trying to make it such that it resets at 360 rather than 0. (since they're the same isn't it?) Waiting for it to slowly go back to 0 is such an inefficient method. After browsing through certain really posts some people mentioned that it can be done on a Haas machine turning setting 108 on. I don't have such a luxury here since I don't use those machines.

Does anybody have any smart commands for the above situation? Any input would be great, thanks!

What controller do you have?

You could try:

G92A0.0

After positioning to A360. or A720. or minus those.

Or if you knew you were at A500.000, you could call:

G92A140.

Some machines use G50 instead. An old Cincinnati I used had a Rotary Axis Unwind G-code that did that automagically.

To 5xmill: I'm using the EMC2

To Beege: I suppose it works but it involves me calculating the required degree for each and every single cut. I wonder if its possible to home it without me manually setting a specific code for it.
