Hello all,
I do apologize ahead of time if I have posted this in the wrong place but I am in need of some help from someone smarter than I in these matters. The problem seems to be when I try to home the x axis. When I try to do a homeall or homex, the endstop stops the motor -or printhead I should say- but I can hear either the driver or motor keep making a noise and the machine does not seem to continue on to run the next gcode command. It hangs after it hits the endstop (or when I manually trigger it) when running G1 S1 X-240 F1800. It does not back off to prepare for the next homing pass (G1 X5 F6000), the next gcode command in the macro. The machine stays busy as I cannot send it any gcode commands manually either. The endstop does show triggered in dwc when I trip it and I have tried a new endstop and that does not change anything. Any ideas on what I can try next in order to diagnose the problem? Thank you in advance!
Here is my homex.g:

G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 X-240 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 X5 F6000 ; go back a few mm
G1 S1 X-240 F360 ; move slowly to X axis endstop once more (second pass)
G1 Z-5 F6000 S2 ; lower Z again
G90 ; absolute positioning
