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

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?

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

@94118 said in Help: Temp Sensors and Homing Issues:

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
