G28 Error: Failed to enable endstops Sensorless Homing Homing
-
I am trying to make Sensorless Homing work on a core-XY machine but whatever I did so far spits out "G28 Error: Failed to enable endstops"
; Endstops
M574 X S3 ; configure sensorless homing for low end on X
M574 Y S3 ; configure sensorless homing for low end on Y
M915 X Y R0 F0 ; configure stall detection
M915 X Y S5 R2

G31 P500 X16.5 Y-20.2 Z1.89 ; set Z probe trigger value, offset and trigger height
M557 X50:250 Y50:250 S50 ; define mesh grid -
Can you provide the results of M122 and M98 P"config.g"?
Also your full config.g and homeall.g files.

M574 X S3 P"xstop" ; configure sensorless homing for low end on X
M574 Y S3 P"ystop" ; configure sensorless homing for low end on YIf you're using sensorless you can remove the P"xstop" and P"ystop" parts since you;re not using actual switches you don't need to define pins.

@tkdirp I have same issue did you ever find out the resolve?
-
@daimein2007 Same problem I would to declare an axis without homing process

If you have an axis that doesn't need to be homed, use a G92 command to sets its position. For example, if you create a U axis that doesn't need to be homed, put just this command in the homeu.g file:
G92 U0
Also add that command to homeall.g.

@dc42 Thanks You answer quicker than me, I have just did it now by adding M92 C0 in my homing file !
Thanks ! -
@dc42 I'm not sure if this is right for me I'm using 2209's I have installed a RepRap board on an skrv1.3 which converts to duet and uses duet firmware I set everything up for sensorless homing and used the https://teamgloomy.github.io/Configurator/Start
tool to configure it I just keep getting this even after hours and hours of checking all settings G28 Error: Failed to enable endstops it's almost like homing itself is not enabled if that's even possible. I get it when trying x or y z is setup on bltouch cant do z without x and y i have searched every square inch of config and setup my x y and z but nothing is it possible there could be a bug. I have a duet2 wifi on my delta never had this problem. -
