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

G1 H2 Z5 F6000 ; lift Z relative to current position

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

94118

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?

94118

Yes that is correct

Phaedrux

Can you send movement commands in the console?
Do the paneldue move buttons work?

94118

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.

G91               ; relative positioning
G1 H1 X235 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X5 F6000    ; go back a few mm
G1 H1 X235 F360  ; move slowly to X axis endstop once more (second pass)
G90               ; absolute positioning

Should be

G91               ; relative positioning
G1 H1 X235 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 X-5 F6000    ; go back a few mm
G1 H1 X235 F360  ; move slowly to X axis endstop once more (second pass)
G90               ; absolute positioning

Your homey has the negative, but you don't need the H2 on the second move.

G91              ; relative positioning
G1 H1 Y215 F1800 ; move quickly to Y axis endstop and stop there (first pass)
G1 H2 Y-5 F6000  ; go back a few mm
G1 H1 Y215 F360  ; move slowly to Y axis endstop once more (second pass)
G90              ; absolute positioning

Should be

G91              ; relative positioning
G1 H1 Y215 F1800 ; move quickly to Y axis endstop and stop there (first pass)
G1 Y-5 F6000  ; go back a few mm
G1 H1 Y215 F360  ; move slowly to Y axis endstop once more (second pass)
G90              ; absolute positioning

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

G91               ; relative positioning
G1 H1 Z200 F1800 ; move Z up until the endstop is triggered
G92 Z0            ; set Z position to axis minimum (you may want to adjust this)

Should be

G91               ; relative positioning
G1 H1 Z200 F1800 ; move Z up until the endstop is triggered
G1 Z-5
G1 H1 Z200 F360 ; second pass
G92 Z0            ; set Z position to axis minimum (you may want to adjust this)
G90 ; absolute positioning

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

What exactly do you mean by that? Can you post a photo of what you're trying to use?

I would use the jog controls for filament load and unload as well as jams or clogging

Phaedrux

The extruder motor won't move unless it's at printing temp.

Are the x and y and z jog buttons working?

94118

they will work only if i press the plus side of the controls then press the negative side

Phaedrux

Ok that probably means that your endstop positions and/or your motor directions aren't correct.

Where is the X endstop? Left or right side?
Where is the Y endstop? Front or back?

Perhaps take a look at this guide on commissioning a printer: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+3:+Commissioning/39

X is at the Right, y is at the Left rear corner
