Yes that's exactly what it does, I use a probing routine in SheetCam to find the surface before every pierce happens.

Have not used run from here yet

I don't really know if the odd value for my Z zero machine DRO matters, I know the work DRO get zeroed each time it probes.

It does have a home switch but that's at the top and just functions as a limit switch now incase I rack the z up manually too far. No point in homing a z axis on a plasma as it's always changing with material thickness and warpage etc.

Is there a way to manually zero a machine DRO?

Still no reply from CandCNC, are they still going?

I did get one from a guy going by the name of randyray but he said he could not help interface it to my torch as it's not for automation.

Hmm, I read about this gotoZ button but my screen set not seem to have it.

I do have a goto zero button is that the same?

Looking at it another way, if I don't have it then I probably don't need it as I never knew it existed.

Is RFH ref home or all ? If so the my z axis does not move when doing doing a ref all, it can't as there could be nothing under the torch and it will simply plant itself in the slats.

My Z axis machine coordinates never gets zeroed and seems to be at some arbitrary point about 5mm below bed level?

Is there a way to zero machine coordinates manually?

Many thanks, knew there would be a way

Just thought, I can add a button to my screen but what's the best code to put in it?

It would need to jog to the same max Y point as manually jogging would, preferably using the safe deceleration zone near the limit as well.

Hi

could someone spare a minute to explain what safe-z actually does or should do in respect to a plasma table??

I have been seeing the "safe-z turned off......" message today, but it makes little sense. I have tried various settings in the safe-z screen but nothing seems to do what i would expect it to, probably my fault

When is safe-z called?

I have tried the "make safe-z an incremental rise" but that seems to do little

Any advice would be helpful, even if its just "turn it off" as long as that is followed by how to turn it off

Dont forget this is a plasma so Z DRO is zeroed at the top of the workpiece NOT the top of Z travel, this effectively means that Z machine co-ords are never zeroed, currently it seems to think that machine Z zero is at table surface -4mm !!!

In the standard Mach3 Plasma setup, is there a keyboard button or shortcut lurking anywhere that can be pressed to rapid the gantry to Ymax position???

My little machine is front loading and the torch parks at 0/0 which is right in the way.

Thought it would be handy to have a F button or something that just shoots the gantry to the furthest position.

But does it work at speed too?

I have tried contacting them for two days now but no response at all.

No objection to buying one if it works but can't do anything without a reply

Hi

I have rate set at 9 and anti dive at 90%

I tried lowering anti dive but makes no difference, might try turning it off.
