Ouickie: Is their a way to disable and enable motors so that i may level my bed with my Boro glass.
-
-
When homing Z at the end of run Command it is hitting my nozzle causing my bed to tilt a few degrees
-
Post your homing files.
Is it using a probe, or an endstop?
If the nozzle is hitting the bed before the endstop is triggered you'll need to move the endstop so that it gets triggered first. If it's hitting the endstop but not stopping you should test the endstop switch to see if it's triggering at all when pressed.

And if you hit the endstop with your finger does the status change in the machine specific tab?
-
Had to issue M84 and manually lower my bed to test trigger my z endstop status states NO when not hit then turns to YES when Hit

Remove this from homez. Maybe you were already too close to the endstop at the start of homing.
If you lower the bed and then home does it move towards the endstop?
Try and click it with your finger before the bed hits it. If the endstop doesn't stop it moving, power off the printer to prevent damage.You can also use M913 Z40 to reduce the motor current at the start of homez and then use M913 Z100 to return motor current back to normal at the end. That should also help limit the potential for damage.

That worked: Nice soft Stop at my endstop and adjusted my height down to 200mm was set at 205mm would it be better to just remove the Z movement from X and Y also

You could since you aren't using a probe or anything that would need to be raised above the bed before movement.
-
Would i be all good to load filament and try a test print
-
Machine movement controls not responsive i click on the fine movement tabs and it does noting machine is in idle
-
So the printer will home properly but then you can't use the jog buttons in DWC?
-
Yes that is correct
-
Can you send movement commands in the console?
Do the paneldue move buttons work? -
No i cannot send commands from console or paneldue
-
Please post your current config.g and homing files so I can see what state your machine would be in after homing.

In homeX you should have a negative move to back off the endstops.

You may want to add a second slower pass. You're also missing the G90 at the end, which could be your movement problem.

Got it to home correctly still cannot use jog controls for fine movement
