I have several older machines using fanuc, closest are 10M control's.
Depending on the parameter setup, I have never needed G53. However I understand it's importance. I refer you here... G28 Versus G53 : Modern Machine Shop

this simple macro works for me, again 10M fanuc with tweaked parameters.

I know, each machine has it's quirks.

Thanks but that looks more like a g code insert after looking at it. Or a post fix. I need a Mach 3 m6 start macro to insert .

no G28 will work I was just trying to keep z down a bit so I can change tools easier lol. I will try that 1 out . Thanks

Keep Z down a bit? lol, i'm confused. Tool changer messed up? I often don't see things so...

Yeah, I'm lost, lol.

No my IH cnc has a nice height to it and I'm 5'8" no reason to go to full home unless I have to . That is a lot of travel time .if I use a G53 in place of a G28 I can control the height and won't have to have such a reach to change the tool and I can have it 4 inches lower with out any crash issues with my work piece. I mean I could use a G28 but rather use the G53


@alex i havr tried that tool change macro that worked ok on screen but when I loaded it to my mill it would keep cycling up and down after the tool change message and not go past the m6 t# .
