Reset 4th axis output when reaches -360/+360 degrees

[Anonymous]

Hi,

I have a customized Mach3 post for a 4th rotary axis (A, although it turn around Y). I made it for a RichAuto controlled Blue Elephant ELE1325-8 machine. I have been experimenting with the Rewind or simply limiting the rotation from the MachineConfiguration. I don't really like to rewind the machine after a long Rotary Strategy, and I've just found out that when in jogging mode the machine goes over -359/+359 to 360 it simply nulls the number and goes on from there.

So, my question is, is there a way to trim the rotary axis output in post, so instead of:

G1 A359

G1 A361 ----> i get simply G1 A1, and the same way in the negative direction (A-361 to A-1)

It turns out if I manage to do this, I would not need a long rewind at the end of the program run and still be able to use Spiral mode in the Rotary strategy. (up until now I only used the circular)

Any help appreciated! 🙂

What settings do you have in Mach3 General Configuration for your Rotary axis ??

If you are doing a long Rotary Spiral Toolpath then the machine will do many more degrees than 360 which is what I assume is happening and it is doing the whole Spiral back to the start??

You could remove the A0 at the end of the program and the Rotary will stop at the end of the Lead out that has been set in the program.

Stay Safe
