EndStops
-
Hiya,
I have connected the endstops to the duetwifi to the point of the lights on the board lighting up when the endstops are activated.This is great, however they don't seam to be triggering anything when for example i move the y axis by 100mm.
when i send the M119 command it can tell when whether the endstop is activated or not.
The z probe on my system lights up when a metal peice is touching the sensor, but again the axis doesn't stop.
Please Help.
I am using the Reprap configuration tool to build the config file
Kind Regards,
Nazim
My config file is as follows:

It looks a bit like you are using a probe configuration which is for a very early version of firmware (1.16 or earlier). It would help us if we knew what sort of end stop you are using for each axis, where on the axis they are positioned and what type of probe (if any) that are using for Z.

Endstops only cause homing moves to be terminated, not ordinary moves. Homing moves are G1 moves with the S1 modifier. After homing, software endstops limit the axis movement.

the z probe is connected to one of the vin connectors, and the rest are connected to the E0 connectors
the z probe i've got is similar to the one in this link: NPN, proximity sensor,

Like DC42 said, the endstops will only trigger during the homing sequence. You can crash the endstops prior to homing. There is a way to make it so the endstops act as a fail safe during normal operation and before homing is done but so far my results are buggy at best trying to implement it (can cause emergency stop shutdown loops) I have not yet had time to revisit it to see if i can come up with a working gcode example for you

Thanks guys,
knowing that the endstops, are only activated on homing.how would i define/ apply the following settings using the reprap configuration tool, for software based end stops.
[[language]] #define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS. #define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below. // Travel limits after homing #define X_MAX_POS 220 #define X_MIN_POS -45 #define Y_MAX_POS 220 #define Y_MIN_POS -5 #define Z_MAX_POS 230 #define Z_MIN_POS 0 #define X_MAX_LENGTH (X_MAX_POS - X_MIN_POS) #define Y_MAX_LENGTH (Y_MAX_POS - Y_MIN_POS) #define Z_MAX_LENGTH (Z_MAX_POS - Z_MIN_POS) ```[https://configurator.reprapfirmware.org/](https://configurator.reprapfirmware.org/) -
Just enter the corresponding values in the axis minima and maxima fields on the General tab of the configurator.

a nice learning curve, thanks for your patients,
