Silly homing problem

YYCSparks

So I have a strange problem where my X and Y axis will home just fine and my Z will move and I can probe and everything but when I try to home it using the Home Z button it does not move at all.

Any help on what I did wrong as I am sure its pretty easy fix and just something I overlooked.

Here is my Config:

Remove the G92's
They are unnecessary and may cause issues.
See the G1 command notes

YYCSparks

@OwenD okay thank you I will remove that.

However if I put this into the console nothing happens with the Z axis:

G1 H1 Z{move.axes[2].max*2} F900

It should shouldnt it?

OwenD

@YYCSparks
If your Z axis is energised then I would expect that to work.
Try sending M564 S0 H0 ; allow movement before homing first

YYCSparks

@OwenD thanks man. Appreciate the help.
Apparently it was user error. I was messing around with building a tool probe and it was set wrong causing the Z axis to see the probe as tripped and wouldn’t home.

@YYCSparks said in Silly homing problem:

That'll do it
