Mechanical ENdstops
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
image url)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
-
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
-
@94118 said in Help: Temp Sensors and Homing Issues:

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?
