PlasmaC questions new setup

Try changing the Z scale in the ini file to -400

Yes it changes the PgUp behavior but still PgDn the DRO counts up positive.

Where is torch home position to be Up or Down?

So PgUp and PgDn both move up?

Z Home should be at or near Z max limit.

Have messing around in INI, Scale -400 is correct for PgUp torch going up towards Max_Limit and Home switch.

But I cannot get DRO to show 90 as it should ? Or am I barking at the wrong tree?
I have total 105mm and want my home to be like 15mm lower than max
DRO to show 90 when homed.

One of the problems is some people use +ve numbers and others like me use -ve numbers Ie on mine I home at the top = 0 then _ going down that is the way a mill would generally be setup.

Now you have changed the scale to -ve to get the pageup/down correct. It will change all the other setting. like I posted earlier

its up to you my working config that I posted is fine for me. When you have it working you never use the Z touch again

I don't want to muddy the waters as to many cooks spoil the broth. There are many ways to skin a cat.

After you home the machine, jog it all the way to the bottom then do a touchoff with a value of zero. Home the machine again and it should be good to go.

EDIT: from the ini file your home switch is near the bottom, 15mm above Z minimum limit.

Where is your home switch located in relation to your Z maximum limit?

So now I have it working.Config with 0 safe height. After cuts torch returns to 0

11mm under Z max

Re extras:
Is there any way in config to always add G0Z50 at the end of finished cut.

This just avoid leaving Z above home switch when shutting down LCNC

From CAM this could be added in PP
