Please see the post from DC42 above. https://forum.duet3d.com/post/134957

You need YAT connected via USB so that we can see if there is communication between the paneldue and the duet.

Direct from YAT: with Duet 2 plugged in to USB talking to Paneldue

If you are using the ribbon cable, make sure it is plugged into the CONN_SD socket on the Duet. Not CONN_LCD.

In your first picture it shows the PanelDue ribbon cable plugged into the wrong port. Are you still connected that way? Have you tried the 4 wire cabling option?

disconnected ribbon cable now it shows Idle And Temps

Phaedrux

So it's working now? Your responses are so short it's hard to know what's actually going on, which makes it very challenging to help you out.

I have and got it working by removing the ribbon cable. Now i think its my endstops conflicting with homing controls and commands (https://drive.google.com/open?id=1DxrsV36-5PN991DjbJJKdIKGP0n85crk) picture included status of endstops state Yes

Phaedrux

If the endstop state says that it' triggered when it's not, then it's likely been defined incorrectly for the switch type.

I don't know what type of switches you have, or how the endstops have been defined in config.g.

https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration

It's likely a case of needing to change an S0 to S1 or vice versa.

Homing still an issue Please review my config.g File i will Send config.g

Yes, but what kind of switch is it? Normally open, or normally closed? Do you have a picture of the switch?

; Endstops
M574 X1 S1 P"xstop"                            ; configure active-low endstop for low end on X via pin xstop
M574 Y2 S1 P"ystop"                            ; configure active-low endstop for high end on Y via pin ystop
M574 Z1 S1 P"zstop"                            ; configure active-low endstop for low end on Z via pin zstop

~~As I mentioned above, you may need to change the S1 to S0.~~

With RRF3 you need to use a ! to invert the signal, so try

; Endstops
M574 X1 S1 P"!xstop"                            ; configure active-low endstop for low end on X via pin xstop
M574 Y2 S1 P"!ystop"                            ; configure active-low endstop for high end on Y via pin ystop
M574 Z1 S1 P"!zstop"                            ; configure active-low endstop for low end on Z via pin zstop

Just replaced Hotend heater and Thermistor did Heater auto tune and it was successful with New 24v 40W Heater Cart. and an NTC 3950 Stud Thermistor

Features:
Using 22AWG cable, the copper inside is very thick, it is resistant to current 2A, voltage 300V.
The nonconductor has a wide range of temperatures, up to 80 centigrade.
It is not easy to be snapped and convenient to be plugged in and unplugged.
For convenience, the plug on the other side is integrated , you can use the plug directly.

Connection description:

Bed wire connect VCC (+ of ramps)
Black wire connect GND (- of ramps)
Green wire connect SIGNAL (s of ramps)

One set includes:

1x endstop switch
1x 3-pin 27.5inch cable

What is in the package:
2 set endstop switches for RAMPS 1.4

Phaedrux

Yes those switches would likely need to be inverted. See my post above.

What firmware version are you running exactly? Send M115 and post the response.

console (2).txt Results posted Fixed my Z and Changed my endstops to inverted with the Exclamation Fix Thanks

M500: Warning: No M501 command was executed in config.g

Don't forget to add M501 to the end of config.g or your tuned values won't be loaded at boot.

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

Phaedrux

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.

Z axis goes a few mm beyond my Z Endstop which forces my endstop to slightly be tilited up

And if you hit the endstop with your finger does the status change in the machine specific tab?
