Homing X and Y can't jog after homing?

Ok so I have managed to get the homing all sorted out except after all 3 axis homes the x and y axis won't move when I try jogging them, the z axis jogs no problem. I'm wondering if it's not coming off of the limit switches far enough but I can't seem to find where to change that. If Infact that is the problem?

If it's still on a limit switch after homing it would error.
softlimits could do that.

How are you jogging?

Can you post your config files.

I try jogging with the keyboard and with the mouse on linuxcnc in the - direction.
here are my config. files.

so it doesn;t move at all ?
not even .001 ?

It might move a .001 but I didn't notice it.I wasn't looking at the drop, just watching the table.

My guess (and its a guess) is that you don't have axis direction the same as linuxcnc thinks it is.

Everything hinges on the direction being the way linuxcnc assumes.
The screens show tool direction and depending on your machine it can be opposite of what you expect.

note in this diagram the top right shows tool movement but the movement shown on the machine's table is opposite.
linuxcnc.org/docs/2.8/html/user/user-con...chine-Configurations

Here is a homing example diagram (this is from 2.8 docs, but the diagram is the same in 2.7):
linuxcnc.org/docs/2.8/html/config/ini-ho...witch_example_layout

So you must start with the _tool_ moving in the positive direction when you press the positive jog key, even if it's not the tool moving.

It's kinds hard to explain and that might not be your problem but it seems to lead me there.

I just checked and it moves exactly .001 in both x and y but won't move anymore after that.

ok that pretty much confirms my hunch.
Either your axis directions are backwards on x and y or your homing directions are backwards.

Looks like you are using shared both limits and homing, so there is no way for linuxcnc to know if you homed towards the wrong side.

Can you describe your machine or show a picture. My guess is the tool moves up and down but the table moves for x and y?
If so when you press the positive X jog key, the table should move left.
Positive Y the table should move towards you.

Is that true?

When standing in front of the mill, positive x goes to my right, positive y towards me. The table moves.
