hIYA Ian I was just pulling your leg(;-).
I knew that
The G28.1 method uses a % of rapid as defined in Config/homing. It IS adjustable.
In the SECOND stage yes - but the guide says the FIRST stage is done at FEEDRATE - which it isn't - it's done at 100% RAPID.
Also with the G28.1 function there IS a waypoint feature. With this you can direct the Z to move to the way point at rapid then finish the function at home speed.
That's what I'm saying
With Plasma you are rarely anywhere but a 0.100 " or so off the top of material at any time.
Well I'd say that depends on what you're cutting and how much it's warped/may warp upwards for whatever reason - but anyway let's say 0.1 is OK
So I just do
G28.1 Z.500 That sends the Z UP to .500 at rapid as a SAFEZ and then resumes the Home function at the preset speed I have defined.
I don't get this bit. If 0.1 is safely above the material why would you send it further up before coming down again - seems a complete waste of time to me with no benefit.
I use SafeZ as .500 as it is not safe to go zooming around the thin guage material as it warps and there may be kickups hidding that will tear the torch right off the head IF you are just skimming the top of the material.
Sorry if I'm being a bit slow but a minute back you seemed to be saying 0.1 was safe.
