Random Questions on setup

HOME is where the Z axis moves to at HOME_FINAL_VEL to complete homing, it is not a requirement that this is zero.
linuxcnc.org/docs/devel/html/config/ini-homing.html#_home

So this :
Final Pos = -.125 <<<<<< notice - in front of value
Home switch location = 0
should probably be reversed, is that correct?
I will edit the above post after confirmation, thank you.

It looks to me that he would like Z axis top to be positive and that his limit switch is at the top so I think something like: The MIN and MAX should be set the same in the AXIS and JOINT sections.

A "conventional" setup would more be like:

So this is what I wound up going with
MIN_LIMIT = -7.00
MAX_LIMIT = 0.00
HOME_OFFSET = -2.00
HOME = 0.00

I tried the other configurations and changing home latch direction, some would cause Z to just jam up into the ballnut or put the axis in a bad position for travel. the problem im seeing is im telling it to go to -2.00 but when it parks the DRO reads 2.993 if i change the Home offset to -4.00 it goes to -4.993 so not sure what that is all about.

As it is Homing Z seems sufficient now. but with odd results

OH... while performing all this one of the runs caused the Z to dig into the plate and trip my probe switch. this caused an error and was unable to bypass or override the switch to get the Z axis into a better place. Am I overlooking something? error stated Jogging was not available and since i hadn't homed it all i could MDI my way out of it.

HOME_OFFSET is the location of the home switch.
Where is your z home switch located in relation to the top of Z travel?


Override Limits on the SETTINGS tab should allow you to jog after hitting a limit.
 

Switch is at the top most portion of Z axis.

Ill look on the settings tab again today. still trying to work my way around QTPlasmac.

Also is there a way to change the Velocity position and Size on the screen?
Oh and switch the Buttons on the Jog like switch + and - 

Also is there a way to change the Velocity position and Size on the screen?

Position - not easily (it's an open source project so there's usually always a way)
Size - yes. Follow these directions: linuxcnc.org/docs/devel/html/plasma/qtpl...#_add_a_custom_style

inside of qtplasmac_custom.qss, add these lines:


That will change the size of the VEL: label and the indicator to 14pt font, in this case.

Oh and switch the Buttons on the Jog like switch + and - 

Again, no, not easily. but why would you want to? The X and Y indicators in the preview point toward X and Y positive. The GUI buttons follow as pictured below:



To do anything else would be ... wrong.

Maybe you are expecting the table to behave differently given the orientation of your control console. In that case, .ini file changes are in order....
