Endstops do not work on U,V or W

Jacques2023

Hello all,
I am having major troubles with endstop switches. I can configure them to work on X and Y motors (have not tried Z as this is set as a probe) but cannot get them working on U, V or W. I have high certainty that they are plugged into the correct position on the board as when I press the endstop switch I can see the led going off next to the respective motor.

Below I have put my config file. For testing I can send a gcode line via the web interface. When testing X (and similarly for Y), I send:

g91 g1 h1 x500 f2000

and hitting the endstop switch stops whichever direction the motor is moving

When testing V (and similarly for U), I send:
g91 g1 h2 v100 f2000
but endstop switches do not stop when moving either way. Note I need the h2 here for this particular motor

Here is my config file:

Apologies - I am an idiot. The h2 I was using in my testing line was ignoring the endstops. The reason i was using h2 was my motor would not drive with g91 g1 h1 v100 f2000 but if i use g0it does drive with h1. Apologies again
