Auto Reference point cycle

Hi all

I have a stepper system that due to it's famous behavior, machine should do a home all using a special code inside the part program. I searched for a predefined code but found nothing(G28 is not what i want). Anyone have any idea about this? is this possible at all?

Best solution, fix your step loosing problems.

But to try to do something like what you want, try setting up some sort of probe routine then use that data to make adjustments to your machine coordinates (G54...). This likely won't be possible using limit switches as the probe inputs, but a separate home switch(s) should be workable.

As Todd said you may be able to use a probe routine.

So a sub to...

Possibly use G28 to take the machine close to the switches position.

Then probe one axis at a time.

Then set offset with G10

Then probe next axis.
May work with switches hooked up in series.
